Align OpenAI model defaults and examples with GPT-5.4 variants

[PeterDaveHello]

Update the default OpenAI model configuration and align the commented reasoning and weak model examples with the GPT-5.4 family.

Refresh the configuration-facing documentation so that local setup requirements and reasoning-effort guidance match the updated configuration examples.

⚡ Recommended focus areas for review Possible Issue The fallback model configuration has been updated to ["gpt-5.4-mini"], but it is unclear whether this model provides sufficient reliability compared to the previous fallback models (["gpt-4o", "gpt-3.5-turbo"]). If gpt-5.4-mini has narrower capabilities or higher latency, it could degrade performance in scenarios requiring robust fallback handling. # Add a fallback model for better reliability config.fallback_models: '["gpt-5.4-mini"]' Configuration Clarity The commented lines for model_reasoning and model_weak introduce new optional configurations (gpt-5.4-mini and gpt-5.4-nano). However, their intended use cases and impact on performance are not explained. This could lead to confusion for users attempting to customize their setup. #model_reasoning="gpt-5.4-mini" # dedicated reasoning model for self-reflection #model_weak="gpt-5.4-nano" # optional, a weaker model to use for some easier tasks
