Problem

This morning all models went down on Telegram, completely breaking the bot. Every user hit the same error:

Sorry, I encountered an error (ValueError).
Model MiniMax-M2.7 has a context window of 32,768 tokens, which is below the minimum 64,000 required by Hermes Agent.  Choose a model with at least 64K context, or set model.context_length in config.yaml to override.

The same error fired for kimi-k2.6 (also 32,768 context) on a cron job (facebook-groups-daily-scan):

ValueError: Model kimi-k2.6 has a context window of 32,768 tokens, which is below the minimum 64,000 required by Hermes Agent.

Impact

• Telegram bot completely unresponsive for all users
• Cron jobs also failing with the same error
• Previously working models (MiniMax-M2.7, kimi-k2.6) suddenly rejected with no config change on our end

Environment

• Hermes v0.13.0 (2026.5.7)
• macOS
• Telegram polling
• Models affected: MiniMax-M2.7 (32,768 ctx), kimi-k2.6 (32,768 ctx)

Notes

• Both models were working fine before this error appeared
• No config changes made by user
• Error message suggests setting model.context_length in config.yaml to override — but this was not needed before, suggesting Hermes introduced a new minimum context length requirement in a recent update
