Our pick

For most workloads, choose Gemini 2.5 Pro.

  • 2.5× the context window — better for long documents and agents
  • 17% faster throughput — matters for streaming UX and voice agents

Largest context window in the top tier (1M tokens). Tradeoff: pricier than DeepSeek and slower TTFT than GPT-5 — pick when whole-codebase or whole-PDF tasks matter.

Choose GPT-5 instead if: Best across-the-board quality but the most expensive token rate in the table; pick GPT-5 when reasoning depth or function-calling reliability outranks per-million-token spend.
