How does Claude Opus 4.7 compare?
Detailed Breakdown
Energy Consumption
Claude Opus 4.7 focuses on long-running agentic work. We carry over the Opus-class estimate of ~6.5 Wh per query; Anthropic has published no per-query energy figures for any Claude model. Note that agentic sessions chain many queries, so a single task can consume far more than one query estimate suggests.
Power Source & Carbon
Served via AWS and Google Cloud. We apply the ~350 gCO2/kWh blended intensity used for other Anthropic entries. California SB 253 requires Anthropic to file Scope 1 & 2 emissions during 2026 — the first official disclosure to watch for.
Water Usage
At ~12 mL per query using the ~1.85 L/kWh water factor applied to AWS-hosted Anthropic entries.
About Claude Opus 4.7
Claude Opus 4.7 is a text and chat model from Anthropic, released in April 16, 2026. Long-running agentic work focus — succeeded Opus 4.6 in April 2026. Each query uses 6.5 Wh of energy and produces 2.3 g of CO₂. That's 22x the energy of a Google search — reflecting the computational demands of text and chat.
These figures are estimates derived from hardware specifications and API benchmarks — Anthropic has not published official energy data for Claude Opus 4.7. Actual consumption may vary significantly depending on batching, quantisation, and infrastructure optimisations that we cannot observe from outside.
