Interactive FrontierBench v0.1 leaderboard with GPT-5.6 Sol at 34.4%, Claude Fable 5 at 33.8%, and 8 models ranked by professional computer-work task completion. From the team behind Terminal-Bench.
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 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.
Head-to-head comparison of GPT-5.6 Terra vs Gemini 3.5 Flash across coding, agentic, reasoning, and multimodal benchmarks. Terra leads on terminal coding (87.4% vs 76.2%), Gemini dominates tool use (83.6% MCP Atlas) and costs 40% less. Full pricing, speed, and benchmark analysis.
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 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 Fable 5 (80.3% SWE-bench Pro, $50/1M) vs Claude Sonnet 5 (63.2%, $15/1M). Fable 5 leads all 8 shared benchmarks by +8.2 pts avg — but Sonnet 5 delivers 79% of the capability at 30% of the price. Full comparison with 4 custom charts, pricing deep-dive, tokenizer analysis, and a 10-point verdict matrix.
