Anthropic's Claude Opus 4.6 is arguably the most capable AI model available — but at $7.50/$37.50 per million tokens, it's also the most expensive. For most tasks, you don't need Opus-level power.

  1. DeepSeek V3 ($0.34/$0.50) — 98% cheaper. Rivals Claude Sonnet for coding.
  2. DeepSeek R1 ($0.34/$0.50) — Chain-of-thought reasoning. Matches Claude for math/logic.
