Claude Opus 4.7 vs DeepSeek R1 (0528)
Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.
Anthropic · Mar 2026
The early-2026 Opus release that pushed SWE-bench past 82% and extended the 1M context to the whole Opus line.
DeepSeek · May 2025
The open reasoning model that started it all — RL-trained chain-of-thought, MIT licensed, and a research landmark.
The verdict
These two models don't yet share verified results on the benchmarks we track, so judge them on specs, pricing and intended use. On price the gap is dramatic: DeepSeek R1 (0528) works out roughly 10x cheaper per blended million tokens. Claude Opus 4.7 also takes 1M of context versus 128K for DeepSeek R1 (0528). And DeepSeek R1 (0528) is open-weights (MIT), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
