[Bug] Activate function calling on OpenAI and Anthropic models available on OpenRouter

[nils010485]

Edit: Change feature request to bug.

🥰 Feature Description

Hello,
Currently, when using OpenAI or Anthropic directly as a provider, the models like

• ChatGPT-4o,
• ChatGPT-4o-mini,
• Claude 3.5 Haiku
  Are marked as compatible with function calls.

However, when accessing these same models through the OpenRouter.ai provider, they are not marked as supporting function calls. This discrepancy means that while these models appear function-call compatible on their native platforms, they seem to lose this designation when routed through OpenRouter.ai.

Have a nice day,

🧐 Proposed Solution

Mark them as function call compatible (knowing that sonnet3.5 does not have this issue and is marked as function-compatible on both platforms).

Update: Same issue on Gemini Flash 1.5 (function calling is working on Google as a provider but not on OpenRouter).
A possible alternative would be to let us manually decide which model is compatible with the functions (this prevents being stuck in cases like this...)

Fixed in the last version thanks !
