Claude Opus 5 vs Kimi K3: Opus 5 leads the independent BenchLM aggregate 85.88 to 79.98 and posts a 43.3–43.5% Frontier-Bench score that K3 has never even been tested on.
Claude Opus 5 vs Claude Fable 5: Opus 5 beats Fable 5 on 7 of 12 benchmarks including Frontier-Bench (+9.6) and OSWorld 2.0 — at half the price ($25 vs $50/1M output). Fable 5 edges SWE-bench Pro by just 0.8 pts. Full comparison with radar charts, pricing, data retention, and verdict.
Claude Opus 5 vs GPT-5.6 Sol: Opus 5 leads 9 of 12 benchmarks including SWE-bench Pro (+14.6 pts) and ARC-AGI-3 (3.9× better). Sol counters with Terminal-Bench 2.1 (91.9% Ultra) and DeepSWE. Opus 5 costs 17% less on output ($25 vs $30/1M). Full comparison with radar charts, pricing, and verdict.
Kimi K3 vs GPT-5.6 Sol: Sol leads 6 of 9 shared benchmarks including DeepSWE and Terminal-Bench 2.1. K3 wins FrontierSWE, BrowseComp, and AA-Briefcase at 40% lower cost. Sol Ultra hits 91.9% on Terminal-Bench. Full comparison with radar charts and pricing.
Kimi K3 vs Claude Fable 5 across 35 benchmarks: Fable wins 22, K3 wins 12, 1 tie. K3 leads Terminal-Bench 2.1, SWE Marathon (+7), BrowseComp, and took #1 on the Frontend Code Arena — all at 70% less cost. Fable dominates FrontierSWE (+5.4), HLE (+9.8), and vision. Full scorecard with radar charts and pricing analysis.
Kimi K3 vs Claude Opus 4.8: K3 leads all 9 shared coding benchmarks and costs 40% less. Opus 4.8 counters with independently verified scores, adjustable reasoning, and mature production tooling. Full comparison with radar charts and pricing tables.
GPT-5.6 Luna vs GPT-5.4 mini compared across official coding, reasoning, tool-use, multimodal, computer-use and long-context results, plus pricing and a practical routing strategy.
GPT-5.6 Luna vs MiniMax M3 compared across coding, browsing, 1M context, video input, agent workflows, pricing and open-weight deployment. Luna leads published coding rows; M3 brings multimodal value.
GPT-5.6 Luna vs DeepSeek V4 Pro: a sourced comparison of coding, 1M context, reasoning modes, MIT weights, caching, pricing, tools and deployment economics.
GPT-5.6 Luna vs GLM 5.2 compared across coding, reasoning, long context, tools, pricing, licensing and deployment. Luna has the stronger managed capability package; GLM 5.2 brings MIT weights and lower output cost.
GPT-5.6 Terra vs Claude Sonnet 5: nearly identical standard output pricing, 1M+ context, and a close SWE-bench Pro result—yet sharply different terminal scores, tooling, availability, and intro pricing.
Hy3 (295B MoE, Apache 2.0, $0.80/1M) vs GPT-5.5 (proprietary, $30/1M). GPT-5.5 leads coding (+11-42 pts), but Hy3 fights back on agents: wins MCP Atlas (+3.8), edges HLE w/tools (+1.0), near-ties BrowseComp (84.2 vs 84.4). All at 1/37th the cost. 5 charts, full breakdown.
