Title troubleshooting for XAI

[matthewknill]

What happened?

For all xAI chats, it seems that no titles are being generated even after multiple responses on the same chat:

Version Information

ghcr.io/danny-avila/librechat-dev                latest    ce3b00be875a   2 days ago      1.13GB
ghcr.io/danny-avila/librechat-rag-api-dev-lite   latest    8858d2bd9ff5   2 weeks ago     1.48GB

Steps to Reproduce

1. Select any xAI model
2. Attempt to chat with the model
3. Notice that there are not titles being created

What browsers are you seeing the problem on?

Microsoft Edge

Code of Conduct

[danny-avila]

Working on my end. To help troubleshoot, please share your custom endpoint config, and relevant error logs (only logs for mongo and meilisearch were shared).

Please paste relevant logs that were created when reproducing the error.

Log locations:

• Docker: Project root directory ./logs
• npm: ./api/logs

There are two types of logs that can help diagnose the issue:

• debug logs (debug-YYYY-MM-DD.log)
• error logs (error-YYYY-MM-DD.log)

Error logs contain exact stack traces and are especially helpful, but both can provide valuable information.

Please only include the relevant portions of logs that correspond to when you reproduced the error.

Please also review relevant title settings for your custom endpoint config:

https://www.librechat.ai/docs/configuration/librechat_yaml/object_structure/custom_endpoint#titleconvo

[danny-avila]

Also recommended to update, updating Instructions (docker):
https://www.librechat.ai/docs/local/docker#update-librechat

[matthewknill]

I can confirm I am on the latest LibreChat version.

The following is my config (which is derived from here):

  custom:
    - name: "xAI"
      apiKey: "${XAI_API_KEY}"
      baseURL: "https://api.x.ai/v1"
      models:
        default: ["grok-4", "grok-4-heavy", "grok-3", "grok-3-mini"]
        fetch: false
      titleConvo: true
      titleMethod: "completion"
      titleModel: "grok-4-0709"
      summarize: false
      summaryModel: "grok-4-0709"
      forcePrompt: false
      modelDisplayLabel: "Grok"

Oddly I noticed that the doco had summarize: false so I tried removing it but it did not solve the issue. I also tried removing summaryModel: "grok-4-0709" which didn't work either.

It seems that it does not produce any error logs but this is the debug log (i.e. debug-2025-07-28.log):
