Greptile Summary

This PR adds GPT-5 specific temperature handling to the operatorHandler.ts file to maintain consistency with existing patterns in the codebase. The change detects when a model name contains 'gpt-5' and sets the temperature to 1.0, while keeping the existing temperature of 0.1 for all other models.

This modification aligns the operator handler with the established pattern already implemented in inference.ts, where GPT-5 models use a higher temperature setting (1.0) compared to other models (0.1). The change ensures that all inference calls across the codebase handle GPT-5 models consistently, addressing a gap where the operator handler was missing this model-specific configuration.

The implementation follows the exact same pattern used elsewhere: checking if the model name includes 'gpt-5' and conditionally setting the temperature parameter in the chat completion options. This creates uniformity in how GPT-5 models are configured across extract, observe, and operator functions.

Confidence score: 5/5

• This PR is safe to merge with minimal risk as it's a simple configuration change following an established pattern
• Score reflects the straightforward nature of the change and consistency with existing codebase patterns
• No files require special attention as the change is isolated and follows existing conventions
