# Claude Opus 5

Anthropic, released 2026-07-24

**Verdict: recommended.** Claude Opus 5 delivers near-Fable 5 intelligence at $5/$25 per 1M tokens, with a 1M-token context and 128K output. Anthropic now lists it as legacy: still available, retirement not before 24 July 2027, and Claude Opus 5.5 ($4/$20) is its recommended starting point. Recommended for teams already running Opus 5; new workloads should start on Opus 5.5, which is cheaper per token. Last verified 2026-09-30.

## Pricing

- Input: $5.00 / 1M tokens
- Output: $25.00 / 1M tokens
- Context: 1M ctx; 128K out; legacy; fast $10/$50

## Strengths

- Everyday coding at near-Fable 5 quality — SOTA on Frontier-Bench v0.1 and within 0.5% of Fable 5 on CursorBench 3.2
- Scientific research — strongest generally available model for life sciences, organic chemistry, and bioinformatics
- Cost-effective frontier work — same $5/$25 pricing as Opus 4.8 but with dramatically better performance
- Agentic coding with strong verification — checks its own work, builds test harnesses, catches edge cases other models miss
- Cybersecurity exploitation — intentionally not trained on cyber tasks; Mythos 5 is stronger for vulnerability exploitation
- Maximum raw capability — Fable 5 still leads on the hardest benchmarks and edge-case reasoning
