Common errors and solutions ​

Error messagePossible causeSolution
Error messagePossible causeSolution
400 InvalidParameter: Range of input length should be [1, xxx]The input exceeds the allowed length.1. Create a new session to resolve the error. 2. To avoid this error, simplify your input or switch to a model with a longer context window. For details, see What are the context windows for each model? How do I handle inputs that exceed the context window? 3. If you use OpenCode, configure limit to limit the context window. For more information, see OpenCode.
401 invalid access token or token expired1. You used a general-purpose Model Studio API key (which starts with sk-xxx) instead of your plan-specific API key. 2. Your Coding Plan subscription has expired. 3. The API key is incomplete, contains extra spaces, or is malformed.1. Use your plan-specific API key. 2. Go to the Coding Plan page Coding Plan page to check whether your subscription has expired. 3. Go to the Coding Plan page Coding Plan page to copy your API key again. Ensure that it is complete and contains no extra spaces. 4. If the error persists, reset your API key on the Coding Plan page Coding Plan page and update your configuration with the new key.
model 'xxx' is not supported1. The model is not supported by the Coding Plan. 2. The model name is misspelled, has incorrect case, or contains extra spaces.Use a model ID supported by Coding Plan. Model IDs are case-sensitive and must not contain leading or trailing spaces.
403 invalid api-keyYou are using the general-purpose Model Studio base URL instead of the plan-specific base URL.Anthropic-compatible endpoint: https://coding.dashscope.aliyuncs.com/apps/anthropic OpenAI-compatible endpoint: https://coding.dashscope.aliyuncs.com/v1 Anthropic-compatible endpoint: https://coding-intl.dashscope.aliyuncs.com/apps/anthropic OpenAI-compatible endpoint: https://coding-intl.dashscope.aliyuncs.com/v1
404 status code (no body)The base URL path is incorrect. For example, you have incorrectly set the base URL to https://coding.dashscope.aliyuncs.com/v1 in Claude Code. The correct URL is https://coding.dashscope.aliyuncs.com/apps/anthropic.Anthropic-compatible endpoint: https://coding.dashscope.aliyuncs.com/apps/anthropic OpenAI-compatible endpoint: https://coding.dashscope.aliyuncs.com/v1 Anthropic-compatible endpoint: https://coding-intl.dashscope.aliyuncs.com/apps/anthropic OpenAI-compatible endpoint: https://coding-intl.dashscope.aliyuncs.com/v1

Claude Code: "Switched to native installer" message ​

This does not affect the normal use of Claude Code. You can run claude install in the terminal to migrate Claude Code to the official native installation, and follow the command returned in the terminal to complete the configuration migration.

Claude Code: "Unable to connect" error ​

plaintext
Unable to connect to Anthropic services
Failed to connect to api.anthropic.com: ERR_BAD_REQUEST
Please check your internet connection and network settings.
Note: Claude Code might not be available in your country. Check supported
countries at https://anthropic.com/supported-countries

Cause: On its first startup, Claude Code attempts to connect to api.anthropic.com for initial authentication. This connection fails because Claude Code is not available in some countries and regions.

Solution:

  1. Add "hasCompletedOnboarding": true as a top-level field in ~/.claude.json.

For an automated solution, use Qwen Code. Launch Qwen Code by running qwen in your terminal, and then send the following chat message: Please add "hasCompletedOnboarding": true as a top-level field in the ~/.claude.json file without overwriting existing content.

bash
{
     "hasCompletedOnboarding": true
}
  1. Save the file and restart Claude Code.
bash
claude

OpenCode: "Request entity too large" error ​

This error indicates that the request content, such as code context or conversation history, exceeds the maximum input limit. To resolve this issue:

  1. Run /new to create a new conversation, or run /compact to compress the context. For more methods to mitigate context overflow, see the documentation.

  2. If the issue persists, update OpenCode to version 1.2.16 or later. This version includes a fix for this issue.

OpenCode: "thinking_budget" parameter error ​

Cause: The value of budgetTokens in the opencode.json configuration file exceeds the maximum thinking_budget supported by the current model. Limits vary by model. Adjust your configuration according to the table below.

Model nameMax thinking budget
Model nameMax thinking budget
qwen3.7-plus262,144
qwen3.6-plus81,920
qwen3.5-plus81,920
qwen3-max-2026-01-2381,920
kimi-k2.581,920
glm-532,768
glm-4.732,768
MiniMax-M2.5Enabled by default. The budgetTokens parameter is not required.
qwen3-coder-nextThinking mode not supported.
qwen3-coder-plusThinking mode not supported.

Solution: Open the OpenCode configuration file opencode.json and adjust the options.thinking.budgetTokens value so that it does not exceed the model's limit. For models that do not support thinking mode, such as qwen3-coder-next and qwen3-coder-plus, remove the options.thinking configuration item. For details, see OpenCode.

OpenCode: "max_tokens" range error ​

Cause: The value of limit.output in the opencode.json configuration file exceeds the maximum number of output tokens (max_tokens) supported by the current model.

Solution: Modify the opencode.json configuration file and adjust the limit value for the corresponding model according to OpenCode.

Do Coding Plan models support thinking mode? ​

Most Coding Plan models that support deep thinking have thinking mode enabled by default. To enable it in common tools:

The model you are using must support thinking mode.

For details, see OpenCode. Configure the options parameter as follows:

json
{
  "thinking": {
    "type": "enabled",
    "budgetTokens": 1024
  }
}

budgetTokens is the maximum number of tokens for thinking. You can adjust it as needed.

Open ~/.qwen/settings.json, and in the modelProviders property, set the enable_thinking parameter to true to enable thinking mode:

json

To enable thinking mode in OpenClaw, follow these steps:

  1. Check the OpenClaw version

Run openclaw tui in the terminal to enter the TUI. In the dialog box, enter openclaw --version to check if your OpenClaw version is v2026.03.02 or later. Earlier versions of OpenClaw may not be able to enable thinking mode.

bash
openclaw --version
OpenClaw 2026.3.8 (commit: 3caab92)
  1. Select a thinking level

In the OpenClaw TUI, enter the /think high command to select the thinking level (in this example, high is selected as the thinking level for the current session).

plaintext
/think high
→ high

  1. Modify the configuration file

  2. Setcompat parameter

    Refer to OpenClaw, open the configuration file, and add the compat parameter to the model configuration that supports thinking mode:

    json
    "compat": {
    "thinkingFormat": "qwen"
  }

  3. Setreasoning parameter

    In the same model configuration, set the reasoning parameter to true:

    json
    {
  "id": "qwen3-max-2026-01-23",
  "name": "qwen3-max-2026-01-23",
  "reasoning": true,
  "compat": {
    "thinkingFormat": "qwen"
  },
  "input": [\
    "text"\
  ],
  "cost": {
    "input": 0,
    "output": 0,
    "cacheRead": 0,
    "cacheWrite": 0
  },
  "contextWindow": 262144,
  "maxTokens": 65536
}

  4. Restart the OpenClaw Gateway

After you save the configuration file, run the following command in your terminal to restart the OpenClaw Gateway and apply the changes.

bash
openclaw gateway restart

OpenClaw: Call records for unconfigured models ​

Reason: The openclaw.json file lacks the agents.defaults.models configuration to restrict the range of available models.

Solution: In ~/.openclaw/openclaw.json, explicitly declare the list of allowed models in agents.defaults.models to restrict OpenClaw to calling only the configured models. For more information, see OpenClaw.

OpenClaw: Chat unresponsive after connecting ​

Possible causes include the following:

  1. A local proxy (VPN/HTTP Proxy) intercepts or fails to correctly forward requests to coding.dashscope.aliyuncs.com.

  2. The Base URL in the OpenClaw cache file ~/.openclaw/agents/main/agent/models.json points to an incorrect address, and requests are sent to an unresponsive endpoint.

Solution:

  1. Try to disable the local proxy, or ensure that the proxy can access coding.dashscope.aliyuncs.com.

  2. Delete the ~/.openclaw/agents/main/agent/models.json cache file and restart OpenClaw. After the restart, the cache file will be automatically rebuilt based on the configuration in ~/.openclaw/openclaw.json.

OpenClaw: "OAuth token refresh failed" error ​

This error indicates that you are connected to a third-party OAuth service, not a Coding Plan.

Solution:

  1. Configure the Coding Plan in OpenClaw. For details, see OpenClaw.

  2. Clear the old OAuth credentials and model cache, and then restart OpenClaw.

Before deleting old OAuth credentials, back up the files to allow for a rollback if needed.

bash
rm ~/.openclaw/agents/main/agent/auth.json
     rm ~/.openclaw/agents/main/agent/models.json
     openclaw gateway restart

OpenClaw: "Unknown model" error ​

This error indicates that OpenClaw cannot find the specified model in the configuration file. Check the following items in order:

  1. Incorrect configuration of the models.providers key or model prefix

When you use the Coding Plan, models.providers must contain the bailian key (which can coexist with other providers). In addition, agents.defaults.model.primary must be prefixed with bailian/. The correct structure is as follows:

json
// Configuration file: ~/.openclaw/openclaw.json
{
     "models": { "providers": { "bailian": {...} } },
     "agents": { "defaults": { "model": { "primary": "bailian/qwen3.6-plus" } } }
}
  1. Residual configurations from old providers are causing routing conflicts

If you have previously used other providers such as qwen-portal, leftover provider configurations can cause model routing confusion. Clean up irrelevant providers and ensure that the model pointed to by the primary field is correctly defined in the models.providers.bailian.models list. For configuration information, see OpenClaw.

What is qwen-portal/coder-model? ​

qwen-portal/coder-model is a free model provided by the Qwen Chat web version and is not part of Model Studio. If you try to use this model in Model Studio or Coding Plan, you will receive an error indicating that the model does not exist. Use models supported by Model Studio.

OpenClaw: "No API key found" error ​

This error indicates that OpenClaw cannot find the API key for the provider (xxxxx) specified in the error message. Check the following items in order:

  1. The corresponding provider configuration is missing in models.providers.

Open the configuration file ~/.openclaw/openclaw.json and confirm that a key that matches the provider name in the error message exists under models.providers.

  1. If you connect to Coding Plan, the configuration must include the bailian key (can coexist with other providers).

  2. If the key is missing, add the corresponding provider configuration.

  3. The API key for the provider is incorrectly configured.

    • Ensure that you have entered a valid API key that is not empty and has no extra spaces.

    • If you use Coding Plan, make sure to use the dedicated key (sk-sp-xxx).

    • If the web UI displays __OPENCLAW_REDACTED__, the API key is already saved and does not need to be re-entered. If it is blank or displays YOUR_API_KEY, you must enter the key again.

  4. An outdated local credentials cache is preventing the new configuration from taking effect.

Before deleting old credentials, back up the files to allow for a rollback if needed.

bash
# Delete old credentials and model cache
rm ~/.openclaw/agents/main/agent/auth-profiles.json
rm ~/.openclaw/agents/main/agent/models.json
# Restart the Gateway to apply the new configuration
openclaw gateway restart

OpenClaw: "API rate limit reached" error ​

Check the following items in order:

  1. Incorrect OpenClaw configuration

If the base URL or model provider is configured incorrectly, requests may not be routed through the dedicated Coding Plan channel and are instead routed to general API calls, triggering a rate limit.

  • If you use the Coding Plan subscription, verify that the models, agents, and gateway (including nested fields) in the OpenClaw configuration file are consistent with the configurations in the documentation. For example, the structure for a model service provider is { "models": { "providers": { "bailian": {...} } } } .

  • If you do not have a Coding Plan subscription, switch to one to obtain a dedicated quota.

  1. Subscription quota exceeded: Check your subscription usage on the Coding Plan page Coding Plan page.

  2. Try resetting the API key : If the issue persists after completing the preceding checks, go to the Coding Plan page Coding Plan page to reset your API key.

OpenClaw: "Failed to discover" error on startup ​

OpenClaw shows one of the following errors on startup:

  • Failed to discover Alibaba Cloud models: TimeoutError: The operation was aborted due to timeout

  • Failed to discover Alibaba Cloud models: 404 Not Found

Cause: OpenClaw attempts to query the list of models for the Model Studio Coding Plan, but this model list cannot be queried through an API.

Solution:

  1. This message does not affect the normal operation of OpenClaw and can be ignored.

  2. If OpenClaw does not run properly, check for other error messages.

  3. To suppress this prompt, delete alibaba-cloud:default profile from the ~/.openclaw/agents/main/agent/auth-profiles.json file. For example:

json

OpenClaw: "auth.profiles" error ​

You may see errors similar to the following when using OpenClaw:

  • auth.profiles.qwen-portal:default.mode: Invalid input

  • auth.profiles.qwen-portal:default: Unrecognized key: "apiKey"

Cause: The auth.profiles field in the openclaw.json file was incorrectly modified, such as changing the mode to an invalid value or adding the apiKey field. The auth field stores only authentication metadata, not secret keys. Coding Plan does not need to be configured in auth.profiles.

Solution

  1. Fix the auth.profiles configuration by deleting incorrectly added or modified fields and unnecessary profiles.

  2. Confirm that the API Key for the Coding Plan is configured in models.providers.bailian.apiKey. For more information, see OpenClaw.

"HTTP 401: Incorrect API key provided" error ​

Possible causes:

  • Invalid API Key format: The API Key is empty, has an incorrect format, is incomplete, or contains extra spaces. Make sure that you use the dedicated API Key API Key for Coding Plan, which starts with sk-sp- . Copy the entire key and ensure that it does not contain extra spaces.

  • Expired or invalid Coding Plan subscription: A Coding Plan-specific API key depends on the subscription status. If your Coding Plan subscription has expired or is invalid, the corresponding key will no longer work. Ensure that your subscription is active.

  • Incorrect Base URL: You have configured a Coding Plan-specific API Key (which starts with sk-sp- ), but the Base URL is still set to the standard Model Studio address, such as https://dashscope-intl.aliyuncs.com/compatible-mode/v1. Based on the AI tool that you are integrating, replace the Base URL with the corresponding Coding Plan-specific address from the table below.

ToolProtocolBase URL

VSCode ClineOpenAI-compatiblehttps://coding-intl.dashscope.aliyuncs.com/v1
Qwen CodeOpenAI-compatiblehttps://coding-intl.dashscope.aliyuncs.com/v1

  • Incorrect API Key used: You configured the dedicated Base URL for Coding Plan, but incorrectly entered the general-purpose API Key for Model Studio, which starts with sk-. Please update the API Key to the one dedicated to Coding Plan: API Key API Key.

  • Configuration error caused by a stale OpenClaw cache: In the ~/.openclaw/agents/main/agent/models.json file, delete the providers.bailian configuration item, and restart OpenClaw.

"Authentication failed" error with ModelScope token ​

This error indicates that you are connected to the third-party ModelScope service, not a Coding Plan. To connect to a Coding Plan, see Connect to client or development tools.

This error occurs when you provide an incorrect credential for the ModelScope API service. Check the following items in order:

  1. You entered the wrong access credentials for the platform: A ModelScope token is in the format ms-xxx , while a general API Key for Alibaba Cloud Model Studio is in the format sk-xxx. The two are independent platforms, and their access credentials are not interchangeable. Go to ModelScope to obtain a token.

  2. Incorrect format: Ensure that there are no extra spaces or line breaks when you copy the ModelScope token.

"Only available for Coding Agents" error ​

This error indicates that the call was made from an unsupported tool or environment.

The Coding Plan is exclusively for use within programming tools, such as Claude Code and Qwen Code, and is not supported in tools like curl, Postman, or Dify.

Billing and quota issues ​

Unexpected charges with a Coding Plan ​

If you continue to incur charges or have an overdue payment after subscribing to a Coding Plan, this may be for one of the following reasons:

  1. Incorrect configuration of the plan-specific API Key and Base URL (Most common reason)

    • Cause: If you configure your AI tool with a general-purpose API Key (in the format sk-xxx) and a general-purpose Base URL (which does not contain the coding keyword), the system identifies the calls as pay-as-you-go and bills them accordingly.

    • Solution: You must use the configuration dedicated to the Coding Plan. The API Key  must be in the format sk-sp-xxx, and the Base URL  must contain the  coding  keyword (such as https://coding-intl.dashscope.aliyuncs.com/xxx). For more information, see Obtain a Dedicated API Key and Base URL for a Plan.

  2. Overdue payment caused by billing delays (charges incurred before subscribing to the Coding Plan)

    • Cause: Bills are aggregated by the minute, and bill generation may be delayed by a few minutes. For example, an API call made at 16:00 might not be billed until 16:05, which could be after you subscribed to the Coding Plan.

    • Solution: Charges are based on the actual billing time. For details, see Bill queries and cost management.

  3. Using general-purpose API credentials by mistake

    • Cause: If both general-purpose and plan-specific configurations are saved in your tool, some tools (such as OpenClaw) might automatically route requests using the general-purpose credentials, resulting in charges.

    • Solution: We recommend removing the general-purpose API configuration from your tool and ensuring you select a model supported by the Coding Plan. For example, in OpenCode, select a model with the provider labeled 'Model Studio Coding Plan'.

  4. Client cache not cleared

    • Cause: After you configure new credentials, some tools might still use cached versions of the old general-purpose API credentials.

    • Solution: Clear the cache and restart the tool. For example, with OpenClaw, delete the ~/.openclaw/agents/main/agent/models.json file, run openclaw gateway restart to restart the service, and then reconfigure it according to the OpenClaw documentation.

Quota exhaustion ​

  • Lite plan: If you use up your 5-hour or weekly quota, wait for it to reset automatically. If you use up your monthly quota, you must wait until the next subscription cycle for it to reset.

  • Pro plan: If you use up your 5-hour or weekly quota, wait for it to reset automatically. If you use up your monthly quota, you must wait until the next subscription cycle for it to reset.

Auto-switch to pay-as-you-go ​

No. After your Coding Plan quota is exhausted, further API calls will fail with an error, and usage will not automatically switch to pay-as-you-go. To continue using the service, you must wait for your quota to reset in the next subscription cycle.

Free trial and Coding Plan ​

The Coding Plan is a standalone subscription. Its billing and quota system is separate from the free trial program for general-purpose models in Model Studio.

Subscription period calculation ​

Your subscription becomes active at the moment of purchase and expires at 23:59:59 (UTC+8) on the corresponding day of the following month. If the following month does not have a corresponding day, the subscription expires at 23:59:59 (UTC+8) on the last day of that month.

For example: If you subscribe to a Coding Plan on February 3, 2026, it will be valid until March 3, 2026.

Viewing token consumption ​

This is not currently supported. The Coding Plan's quota consumption is based on the number of model calls, not on token consumption. You can view your usage information on the Coding Plan page.

Usage by specific model ​

This is not supported. The Coding Plan page only displays the overall consumption and remaining quota for the entire plan.

Annual subscription ​

Currently, the Coding Plan is only available as a monthly subscription. An annual plan is not yet available.

Auto-renewal failure ​

This may be due to the following reasons:

  1. Setting not yet in effect: Auto-renewal takes effect the day after you enable it, not immediately.

  2. Insufficient funds: Auto-renewal charges are deducted from the payment methods linked to your account. Please ensure your payment methods are valid and have sufficient funds.

Renewal after expiration ​

No, renewal is not supported after the subscription has expired.

Duplicate renewal error ​

Cause: You have already renewed your subscription for the next month, and renewing for additional months is not supported.

Early renewal service period ​

When you purchase a one-month plan, the subscription duration is calculated by calendar month. The plan becomes active upon purchase and expires at 23:59:59 (UTC+8) on the corresponding day of the following month. If the next month does not have a corresponding day, it expires at 23:59:59 (UTC+8) on the last day of that month. If you renew early, the new period extends from the original expiration date.

For example:

  • An initial subscription on March 15 at 10:00 expires on April 15 at 23:59:59.

  • If you renew for one month on April 10, the new expiration date extends to May 15 at 23:59:59.

Using coupons for renewal ​

Yes, you can use general-purpose coupons.

Subscription renewal ​

You can renew the Pro plan on the Coding Plan page or the Renewal page. For information about the discontinuation of renewals for the Lite Basic plan, see the Announcement.

Product features ​

Supported models ​

Both the Lite and Pro plans support all models included in the plan (including Qwen, GLM, Kimi, and MiniMax). For a complete list of models, see the Coding Plan Overview.

Model list updates ​

The list of supported models is updated periodically. For the current list, refer to the Coding Plan Overview page.

Subscription limit ​

Each Model Studio account can subscribe to only one Coding Plan at a time (regardless of whether it is the Lite or Pro plan).

Can you use models not on the list of supported models ? ​

The Coding Plan only supports models on the list of supported models. Using any other model results in an error.

Response speed of Lite and Pro plans ​

The Lite and Pro plans offer the same response speed because they use the same model resources and inference service.

Lite plan renewal and upgrade ​

Effective April 13, 2026, the Lite plan will no longer be available for renewal and cannot be upgraded to the Pro plan. For details, see the announcement.

  • If you have a Lite plan, you can use it until it expires.

  • If you have enabled auto-renewal for your Lite plan, the system will automatically deactivate it 30 days after the announcement date. You can continue to use the plan until the current service period ends.

Thank you for your understanding and support of Alibaba Cloud Model Studio.

Downgrading to the Lite plan ​

No, downgrading is not supported.

Concurrency limit ​

Yes, the Coding Plan has a concurrency limit. The platform dynamically adjusts this limit based on the overall resource load to prevent overload during peak hours and ensure a stable response speed and inference quality for each agent. If you reach the concurrency limit, wait a few moments and retry.

Multi-user support ​

The Coding Plan API key is for personal use only and must not be shared. If the system detects that your API key has been publicly exposed, it may be automatically disabled.

Sharing a Pro plan ​

No. Keep your API key secure. Do not share it with others or expose it in client-side code. If the system detects that your API key has been publicly exposed, it may be automatically disabled.

Model context windows and overflow handling ​

glm-4.7202,752

If you encounter an error for exceeding the context window, we recommend starting a new session. You can also use the following methods to avoid this issue:

  1. Switch models: Switch to a model that supports a larger context window, such as qwen3.7-plus, qwen3.6-plus, qwen3.5-plus, or qwen3-coder-plus.

  2. Reduce irrelevant files: We recommend starting your AI coding tool in the specific project directory and keeping only necessary project files.

  3. Break down tasks: Split complex tasks into smaller subtasks and ask about them individually to reduce the context used in a single request.

  4. Provide precise instructions: Vague requests can trigger unnecessary file scanning. Use clear and specific questions or instructions when using an AI coding tool.

Specific operations vary by tool. For details, refer to Connect to Clients/Development Tools.

Resetting the API key ​

On the Coding Plan page Coding Plan page, click the Reset button next to your Coding Plan API key.

Note

After resetting your API key, you must update it in all the tools where it is used. Otherwise, these tools will stop working.

If a Coding Plan expires and is not renewed, is the API Key reset upon reactivation? ​

Yes, it will be reset. If you renew before the expiration date, your API key will not be reset.

Expiration reminders ​

Yes. The system sends renewal reminders 7, 3, and 1 day before your subscription expires via in-site messages, emails, SMS, and automated voice calls.

Configuring expiration notifications ​

This is not supported. The system automatically sends expiration reminders 7, 3, and 1 day before your subscription expires via in-site messages, emails, SMS, and automated voice calls. Manual subscription is not required.

Multiple API keys ​

No. Currently, only one API key is supported per Coding Plan subscription.

IP allowlist support ​

No. If your API key is compromised, reset it on the Coding Plan page Coding Plan page.

RAM user access to API key ​

Please contact the Alibaba Cloud account owner or a RAM user with administrative permissions to add the Subscription Plans permission to your account.

Using with VSCode ​

Use a VS Code extension that supports OpenAI- or Anthropic-compatible APIs, such as Qwen Code or Claude Code.

Model quantization ​

The models in the Coding Plan, such as glm-5 and qwen3.5-plus, are full-featured versions that have not been subject to quantization or feature reduction.
