#32033 Add "azure/mistral-ocr-4-0" in "model_prices_and_context_window.json"
The new Mistral OCR model is supported for Mistral API and Vertex AI but not yet for Microsoft Foundry (Azure)
We need to update both [model_prices_and_context_window.json](https://github.com/BerriAI/litellm/blob/88e03e548716a45284597edf2b7f47a7e6a66d5f/model_prices_and_context_window.json) and [model_prices_and_context_window_backup.json](https://github.com/BerriAI/litellm/blob/88e03e548716a45284597edf2b7f47a7e6a66d5f/litellm/model_prices_and_context_window_backup.json) to reflect the new model.
