Best for: AI Agents
Ranked on multi-step reasoning, tool-use reliability, and long-horizon stability. Agentic workloads amplify small accuracy gaps.
Updated May 2026. Top 3 this month: R1 0528, Qwen3.5 Plus 2026-02-15, DeepSeek V3.
Podium
How we rank
Agents chain dozens of tool calls per run. Even a 95%-reliable tool-use model compounds down to near-zero after 20 steps, so the gap between the top model and the runner-up matters a lot. We weight SWE-Bench Verified heavily because it is the best proxy for long-horizon agentic success, then reasoning benchmarks, then price.

Field notes
Plan for retries. Instrument every tool call with structured logging and a budget ceiling.
Prefer models with native structured-output mode to avoid JSON-fixup loops.
Cache system prompts aggressively — agentic flows repeat the same preamble many times.
