“Best value”: no other model here reports a higher score at a lower cost for your workload. Scores are self-reported by each maker with different settings, so treat close calls as ties.

How each maker reported it

  • Claude Opus 4.6 Table 2.3.A, p.18

    Opus 4.6 results average 5 trials (SWE-bench: 25) with adaptive thinking at max effort and default sampling. MCP-Atlas is the max-effort score (62.7% at high). Gemini 3 Pro ARC-AGI-2 is Deep Thinking.

  • Claude Opus 4.5 Table 2.3.A, p.19

    Average of 5 trials with a 64k thinking budget, 200k context, default (high) effort and default sampling. SWE-bench, τ²-bench and MCP Atlas are without extended thinking; Terminal-bench uses a 128k budget (57.8% at 64k). GPT-5.1 MMMU is from the MMMU leaderboard.

  • Claude Sonnet 4.6 Table 2.1.A, p.15
