Key figures, per million tokens
| Energy | CO₂e | Water | Price | |
|---|---|---|---|---|
| Input tokens | 424 Wh | 48 g | 1.9 L | €0.44 |
| Generated tokens | 2.5 kWh | 290 g | 11.3 L | €1 |
Of the 26 models in the TokenClimate registry, Mistral Large 3 ranks 9th for carbon intensity per million generated tokens, below the median (681 g). The gap with GPT-6 Luna, the registry's most frugal, is still ×12.
One million generated tokens represents about 2 km in a combustion car.
Frequently asked questions
How much CO₂e for 1 million tokens with Mistral Large 3?
About 290 g per million generated tokens and 48 g per million input tokens (factors ecologits-0.10.2-replay-2026-09 of the TokenClimate registry).
Where do these figures come from?
Factors published in TokenClimate's versioned registry, each with its citation on this page. The full equations and parameters are in the public methodology, at tokenclimate.com/en/methodology.
What is the confidence level?
Medium confidence: derived from a fitted model, or a partial fit completed by a convention.
How can you measure your organisation's real usage?
The TokenClimate dashboard connects to your organisation's Anthropic, OpenAI or OpenRouter admin keys (stored encrypted) and measures cost and CO₂e per team and per model. You can see it in the demo: tokenclimate.com/demo. Locally, the open source plugin claude-carbon measures a Claude Code session.
