Claude Opus 4.7
Anthropic
Anthropic's most capable generally available model (April 2026), with a step-change improvement in agentic coding over Opus 4.6. Features a 1M-token context window at standard pricing, adaptive thinking, and a new tokenizer that contributes to its improved performance (and may use up to ~35% more tokens for the same text).
Strengths
- Anthropic's most capable model with step-change agentic coding gains over Opus 4.6
- 1M-token context window at standard pricing
- Adaptive thinking balances latency and reasoning depth
- 128K max output (up to 300K via Batch API beta header)
- January 2026 knowledge cutoff - among the most recent of any frontier model
Caveats
- New tokenizer may use up to ~35% more tokens for the same text (affects effective cost)
- Premium Opus pricing ($5/$25) versus Sonnet 4.6 ($3/$15) or Haiku 4.5 ($1/$5)
- Extended thinking is not offered (adaptive thinking only)
