I've reviewed existing issues and found no exact duplicates for this specific model reversion behavior. However, the following related issues about model handling may be worth checking:

• [FEATURE]: Default model #12248: [FEATURE]: Default model - discusses needing persistent default model settings
• [BUG]: Empty content error when switching from Cerebras GLM to Claude Opus #11991: [BUG]: Empty content error when switching from Cerebras GLM to Claude Opus - related to model switching issues
• Local Ollama models not included in model listing, breaking plugin model discovery #12243: Local Ollama models not included in model listing - related to model discovery and availability

This appears to be a unique issue involving model state not persisting properly when sending messages, especially with child processes. The model switching back to a default ('big pickle') suggests a state management or fallback logic issue specific to how the currently selected model is tracked during message sending.

Similar thing, started a session in one model, randomly changed to a different one on the fly, seemingly the previously used model
