“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 5 Table 8.1.A, p.148–149
Claude Opus 5 results use adaptive thinking at max effort, averaged over five trials (ARC-AGI-3 at high effort). GPT-5.6 Sol's FrontierBench figure uses Codex and its ARC-AGI-1 figure is at xhigh. The Fable 5 HealthBench Professional figure carries a footnote reading "Mythos 5". Competitor figures come from the developers' own published results or leaderboards.
- Gemini 3.1 Pro p.4
Results as of February 2026, Gemini at Thinking (High); competitors at their highest reported settings, as listed by Google.
- Claude Sonnet 5 Table 8.1.A, p.115–116; SWE-bench variants §8.2, p.116
Claude Sonnet 5 results use adaptive thinking at max effort, averaged over five trials. BrowseComp is the single-agent score (86.6% multi-agent) with a 10M-token limit and compaction. GPT-5.5 Terminal-Bench 2.1 figure uses Codex CLI. Competitor figures come from the developers' own published results.
- Claude Opus 4.7 Table 8.1.A, p.191–192
Opus 4.7 uses adaptive thinking at max effort with default sampling, averaged over 5 trials (Terminal-Bench 2.0 with thinking disabled; Finance Agent at high effort). Competitor figures come from the developers' own published cards or leaderboards.
- Seed 2.0 Pro Tables 3, 8, 11 (pp.9, 13, 16)
ByteDance's own runs. Competitor columns are as printed in the Seed2.0 card (frontier models available in early 2026). Codeforces is an Elo rating. HLE-text under Agentic is with search tools.
- Seed 2.0 Lite Tables 4, 8, 12 (pp.10, 13, 17)
ByteDance's own runs from the Seed2.0 model card, which predates the 260428 snapshot served now. Codeforces is an Elo rating. Seed 2.0 Mini is shown for comparison (same table).
Only each model's own maker's number is shown; scores a maker reports for rival models are left out.
