Which model should you use?

For coding: Claude Opus 4.7 — 64.3% on SWE-bench Pro, 70% on CursorBench. The new king of coding benchmarks. If you want near-Opus quality at lower cost, Sonnet 4.6 at $3/$15 is still excellent.

For reasoning & research: Gemini 3.1 Pro — 77.1% on ARC-AGI-2 and 94.3% on GPQA Diamond. Best for complex analytical tasks.

For computer use / agents: GPT-5.4 — 75% on OSWorld, native software control. First model to beat human baseline on desktop tasks.

For huge documents: Any of the 1M-context models (Claude 4.6, GPT-5.4, Gemini 3.1). All three now support 1M tokens.

On a budget: MiMo-V2-Flash at $0.10/$0.30 per million tokens — open source, 73.4% SWE-Bench. Gemini 3.1 Flash-Lite at $0.25/$1.50 is another option.

For privacy: Llama 3.1 405B. Run locally with Ollama — your data stays on your machine.
