DeepSeek Reasoner (R1): cost, energy and CO₂ per token
This model has been retired, or is being retired, by its provider (shutdown on 24 July 2026). The sheet stays online for reference and to quantify past usage; the current range is on the model sheets page.
What is the footprint of DeepSeek Reasoner (R1)? DeepSeek Reasoner (R1) emits about 14.1 kg of CO₂e, uses 154 L of water and 17.4 kWh of electricity per million generated tokens. Per million input tokens: 2.4 kg of CO₂e, 25.7 L of water, 2.9 kWh. Public price: €2 per million generated tokens, €0.48 for input.

Key figures, per million tokens
| Energy | CO₂e | Water | Price | |
|---|---|---|---|---|
| Input tokens | 2.9 kWh | 2.4 kg | 25.7 L | €0.48 |
| Generated tokens | 17.4 kWh | 14.1 kg | 154 L | €2 |
One million generated tokens represents about 100 km in a combustion car and 3 showers.
Frequently asked questions
How much CO₂e for 1 million tokens with DeepSeek Reasoner (R1)?
About 14.1 kg per million generated tokens and 2.4 kg per million input tokens (factors tokenclimate-v4-2026-07 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.
