GPT-5 vs Mistral Large 2: side-by-side benchmarks, pricing, context windows, coding ability and deployment. Pick the right model for your stack.
Overview
GPT-5: GPT-5 is OpenAI's August 2025 reasoning model for coding, reasoning, and agentic tasks. The API model supports text input and output, image input, configurable reasoning effort, and an immutable gpt-5-2025-08-07 snapshot; OpenAI now classifies it as a previous-generation model.
Mistral Large 2: Mistral Large 2 is Mistral AI's 2024 flagship commercial model with a 128,000-token context window, built for instruction following, multilingual tasks and function calling in agentic workflows. Both releases are now retired on Mistral's own API: mistral-large-2407 on 30 March 2025, replaced by Mistral Large 3, and mistral-large-2411 on 31 May 2026, replaced by Mistral Medium 3.5.
Context window: GPT-5 accepts up to 400,000 tokens, Mistral Large 2 up to 128,000. Confirm the limit for your specific deployment channel before relying on it.
