Greptile Summary

This PR makes two distinct improvements to the Sim platform's model handling and real-time collaboration. The primary change corrects the GPT-5 model definitions by removing temperature capabilities from all GPT-5 variants (gpt-5, gpt-5-mini, gpt-5-nano, gpt-5-chat-latest) and their Azure equivalents. This aligns with OpenAI's actual GPT-5 API capabilities, similar to how reasoning models like o1 and o3 also lack temperature support in the existing codebase. The change affects 8 model definitions total, ensuring that the application's model configurations accurately reflect what parameters are supported by each model type.

The secondary change optimizes collaborative editing responsiveness by reducing the debounce timeout for subblock operations from 50ms to 25ms in the operation queue store. This store manages real-time synchronization of workflow changes, and the debounce mechanism batches rapid consecutive updates to prevent overwhelming the server. The reduction improves user experience by making collaborative editing feel more responsive, particularly when multiple users are simultaneously editing workflow components like input fields or dropdown selections.

Both changes integrate well with the existing architecture: the model capability system already has established patterns for models without temperature support, and the operation queue's debounce mechanism is designed to be tunable for balancing responsiveness against server load.

Confidence score: 4/5

• This PR is safe to merge with low risk as it corrects model capabilities and improves user experience
• Score reflects straightforward configuration changes that align with established patterns in the codebase
• Pay attention to the model definitions to ensure GPT-5 temperature removal is intentional and correct
