Mistral Medium 3 vs GPT-5.6 Terra

Compare recorded price, context, output limits, speed, latency, capabilities, and input/output support. Every missing value stays visible, and unsourced benchmarks are excluded.

This Mistral Medium 3 vs GPT-5.6 Terra comparison is designed for teams choosing between two production model records, not for declaring a universal winner. Mistral Medium 3 by Mistral AI currently records 131.1K context, 131.1K maximum output, $0.40 input per 1M tokens, $2.00 output per 1M tokens. GPT-5.6 Terra by OpenAI records 1.1M context, 128K maximum output, $2.00 input per 1M tokens, $12.00 output per 1M tokens. The tables below separate documented capabilities, commercial limits, directory measurements, and source-linked benchmark evidence so you can see where the data is complete and where independent testing is still required.

Evidence

Verified shared benchmarks

A score appears only when both records include a verified source. It is not treated as a universal ranking.

These two models haven't been measured on the same benchmark yet, so there's nothing meaningful to chart. Comparing scores from different tests would tell you more about the tests than the models — the specs and pricing above are the better guide here.

Workload guidance

Which model should you choose?

Mistral Medium 3 currently leads on larger maximum output, lower recorded input price, lower recorded output price. GPT-5.6 Terra currently leads on larger context. Choose according to the constraints that matter to your workload, then run the same representative prompts against both models before making a production commitment. Neither the larger number nor the lower price is automatically the better choice: prompt quality, tool reliability, modality support, rate limits, data policy, and provider implementation can change the result. Use this page to build a shortlist, confirm current terms in the linked sources, and validate quality, latency, and cost with your own traffic.

Sources and data limits

Prices and hosted performance can change. SyncDev records source references and clearly separates documented specifications from measured values; confirm commercial terms with the provider before deployment.

Questions people ask

It compares recorded context and output limits, token prices, output speed, time to first token, Intelligence Index, modality support, tool and structured-output capabilities, release information, and only source-linked benchmarks verified on both records. Missing information is labeled rather than inferred.
