Claude Opus 5
Anthropic · Released Jul 2026
Recommended
Near-Fable 5 intelligence at half the price ($5/$25 per 1M tokens). SOTA on Frontier-Bench and CursorBench with 85% fewer cyber safeguards than Fable 5. The workhorse frontier model for everyday coding and knowledge work.
Is it right for you?
Good for
- 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
Not good for
- 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
