I am not sure why support has not been added as it is simply a matter of updating the model
strings - low risk. There already is a PR
Thanks for surfacing this and linking the PR!
You’re right that adding new model strings is generally low-risk. The PR process for these updates typically involves:
- Testing verification - Team confirms the model works with Letta’s architecture
- Endpoint configuration - Ensuring proper API endpoint mappings
- Context window/capabilities - Verifying model specs match what’s declared
Current status of Grok models:
Based on recent team discussions (October-November 2025), Grok models weren’t supported on Letta Cloud at that time. The team was aware of the gap but was prioritizing stability for currently supported models.
For PR #3043:
The team is likely reviewing it as part of their regular PR queue. Self-hosted users can test the PR branch directly if they need Grok support immediately:
git fetch origin pull/3043/head:grok-support
git checkout grok-support
Timeline expectations:
Model support PRs typically get merged within a few weeks if testing goes well. For the latest status, the team is most responsive in the Discord #
｜support channel if you want to check on merge timelines.
Appreciate you flagging this - community PRs like this help expand model support significantly!
