Mistral Medium 3.5 API — pricing, context window & access
Mistral Medium 3.5 is Mistral's balanced mid-tier model, with strong general reasoning, coding, and multilingual performance backed by a 256K-token context window and up to 16,384 output tokens. It targets the workhorse tier between small and flagship models.
YepAPI serves Mistral Medium 3.5 over an OpenAI-compatible endpoint with one key that also reaches Mistral Small 4, the coding-focused Devstral 2, Claude, Gemini, Grok, Qwen, and Perplexity Sonar, plus SEO, SERP, and scraping APIs.
What is Mistral Medium 3.5?
Mistral Medium 3.5 is the mid-tier model from Mistral, the European AI lab. It is built to be a balanced workhorse — strong on general reasoning, coding, and multilingual tasks without the cost of a flagship. It carries a 262,144-token context window and returns up to 16,384 output tokens, which covers long documents and most codebases. With particular strength across European languages, it suits teams that want capable, efficient general-purpose inference and value Mistral's multilingual and data-residency positioning.
Build with Mistral Medium 3.5 via YepAPI
Call Mistral Medium 3.5 through YepAPI's OpenAI-compatible /v1/ai/chat endpoint with the model set to mistral-medium-3-5. Existing OpenAI SDK code works after a base-URL and model-name change. For cheaper bulk work, switch to Mistral Small 4; for heavy coding, Devstral 2 — each is a one-string change. The same key reaches Claude, Gemini, and Sonar, so multi-model routing needs no extra integration.
Mistral Medium 3.5 API pricing — $2.10 / $10.50 per 1M tokens
Mistral Medium 3.5 costs $2.10 per 1M input tokens and $10.50 per 1M output tokens on YepAPI. That sits comfortably in the mid tier — above the ultra-cheap Small model but well under flagship reasoning models — making it a sensible default for general production traffic that needs decent quality at a controlled cost. Billing is per token with no minimums.
Mistral Medium 3.5 for multilingual general-purpose work
Medium 3.5 is well suited to everyday production tasks with a European or multilingual slant: customer support, content generation, summarization, and general coding across languages. Its 256K-token window handles long inputs, and its balanced tuning keeps quality high without flagship costs. For teams that prefer a European model or need strong non-English coverage at a mid-tier price, it is a natural default.
