PR Summary by Qodo

Fix OpenAI fallback model for resolution search

🐞 Bug fix 🕐 Less than 5 minutes

AI Description

• Replaces the invalid OpenAI fallback identifier with the supported gpt-4o model.
• Restores multimodal image resolution search when OpenAI is the default provider.

High-Level Assessment

Using gpt-4o is appropriate because the existing model-selection code already uses it for OpenAI vision-capable requests. Broader provider or configuration changes would add unnecessary scope to this targeted fix.

• Replaces the invalid 'gpt-5.6-terra' identifier with 'gpt-4o' in the default OpenAI provider path. This restores model initialization for multimodal resolution searches.
