Code changes

The Git diff shows the following changes to the useCreateNewThread.ts file:

1. Variable Renaming:

   • The variable model is renamed to defaultModel. This change ensures that the function uses the default model settings consistently.

2. Consistent Use of Default Model:

   • In both overriddenSettings and overriddenParameters, the code now checks if the engine of defaultModel is local using !isLocalEngine(defaultModel?.engine). This ensures that the settings are applied based on whether the model's engine is local or not, maintaining consistency.

3. Token Limit Adjustment:

   • The token limit in overriddenParameters now correctly uses defaultModel?.parameters.token_limit ?? 8192. This means that if token_limit is not defined for defaultModel, it defaults to 8192.

These changes make the code more consistent and clear, ensuring that model-specific settings are applied correctly based on whether the engine is local or not.
