curl https://api.gammainfra.com/v1/chat/completions \
  -H "Authorization: Bearer sk-gammainfra-..." \
  -H "Content-Type: application/json" \
  -d '{
    "model": "mistral/devstral-2512",
    "messages": [
      {"role": "user", "content": "Hello, Devstral 2512!"}
    ]
  }'

Or via any OpenAI SDK — see the integrations page for setup with Cursor, Cline, LangChain, the Vercel AI SDK, and others.

Smart routing — or pin this model

You can call mistral/devstral-2512 directly (as above), or let GammaInfra's router pick the best-fit model per prompt. Use gammainfra/auto as the model name for task-aware routing, gammainfra/fast for latency-optimized hedged requests, or gammainfra/cheap for cost-optimized routing. The router considers task type, latency, and your X-GammaInfra-Cost-Quality dial when picking.

Frequently asked questions

How much does Devstral 2512 cost through GammaInfra?
Devstral 2512 (mistral/devstral-2512) is billed at the Mistral pass-through rate — $0.4 per 1M input tokens and $1.6 per 1M output tokens, with 0% token markup. GammaInfra's fee is taken at top-up time (3% during the launch window through 2026-06-23, 5% after), not per token; the BYOK option is 1–2% per request instead. Every response returns X-GammaInfra-Cost-USD with the exact spend for that call.
What is Devstral 2512's context window?
Devstral 2512 accepts up to 128K tokens of input context and returns up to 32K output tokens per request. GammaInfra passes the full window through with no truncation. Check this model's Specifications and notes above for any provider long-context surcharge on very large prompts.
Does Devstral 2512 support tool calling, vision, and JSON mode?
Tool / function calling: Yes. Vision (image input): No. Native JSON / structured-output mode: Yes. When tool calling is used, GammaInfra translates tool-call IDs across providers so OpenAI-shaped agent code keeps working regardless of which provider serves the request.
How do I call Devstral 2512 through GammaInfra?
Point any OpenAI-compatible SDK at https://api.gammainfra.com/v1 with your sk-gammainfra-... key, then set the model to mistral/devstral-2512 to pin Devstral 2512 directly — or use gammainfra/auto to let the smart router pick it when it is the best fit. Only base_url and api_key change; the rest of your OpenAI SDK code is unchanged.
When does GammaInfra's router pick Devstral 2512?
Devstral 2512 heads or appears in GammaInfra's code dispatcher chains. With gammainfra/auto the router selects it when a prompt classifies into one of those task types and your cost/quality preference fits; pin mistral/devstral-2512 to force it regardless of routing. The X-GammaInfra-Endpoint response header always reports which model actually served the request.
