GPT-5.6 Sol vs Claude Fable 5: Sol leads on agentic coding and price; Fable leads SWE-bench Pro and aggregate intelligence. Rich charts, radar, cost math, and sourced guidance.
GPT-5.6 Sol vs Terra: a detailed family comparison across pricing, 1M context, coding, professional work, science, computer use, charts, radar, and a practical routing strategy.
GPT-5.6 Sol vs Claude Opus 4.8: detailed comparison across pricing, caching, 1M context, coding and professional benchmarks, long context, MCP Atlas, graphs, radar, and routing guidance.
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.
Hy3 (295B MoE, Apache 2.0, $0.80/1M) vs Claude Sonnet 5 (proprietary, $10/1M). Sonnet leads every shared benchmark (+0.5 to +8.7 pts). But Hy3 ties on BrowseComp (84.2 vs 84.7), leads MCP Atlas (79.1%), costs 12.5x less. Open-weight agent vs proprietary coder — 5 charts, 10-point verdict.
Hy3 (295B MoE, Apache 2.0, $0.80/1M) vs GLM 5.2 (753B MoE, MIT, $4.40/1M). GLM 5.2 wins every coding benchmark by 4-18 points. Hy3 counters with MCP Atlas #1 open-weight (79.1%), BrowseComp 84.2%, DeepSearchQA 91.0%, 47% fewer tokens, and 5.5× cheaper. Full comparison with 5 charts and a 10-point verdict.
Claude Sonnet 5 vs DeepSeek V4 Pro: Sonnet leads every coding benchmark (+7.8 Pro, +9.2 HLE tools). DeepSeek is #1 global on LiveCodeBench (93.5%), MIT open-weight, and 7.8× cheaper per task ($0.12 vs $0.90). Is 7.8 more Pro points worth 7.8× the cost?
Claude Sonnet 5 vs Qwen 3.7 Max: Sonnet leads coding (+2.6 Pro, +4.8 Verified). Qwen dominates math (92.4% GPQA), runs 35-hour autonomous agents, and is 2.7x cheaper ($3.75 vs $15 output). The coder vs the marathon runner — full comparison.
Claude Sonnet 5 vs Gemini 3.5 Flash: Speed vs Depth. Sonnet leads every coding benchmark (+8.1 Pro, +4.2 TB). Gemini leads MCP Atlas (83.6%), is 4x faster (289 tok/s), 2x cheaper. Coding specialist vs tool orchestration speed king — pick your weapon.
Claude Sonnet 5 vs GLM 5.2: near-ties on every benchmark (±0.6-2.7 pts). GLM 3.4x cheaper on output, MIT open-weight, self-hostable. Sonnet has OSWorld, BrowseComp, Anthropic safety ecosystem. Proprietary premium vs open-weight value.
Claude Sonnet 5 ($3/$15, June 30) beats GPT-5.5 ($5/$30, April 23) on every directly comparable benchmark: +4.6 SWE-bench Pro, +2.2 Terminal-Bench 2.1, +5.2 HLE with tools. At 40% cheaper input and 50% cheaper output. Full benchmark comparison.
