Anthropic introduced Claude Opus 5, its latest flagship model, which claims to match Fable 5 performance while costing half as many tokens. The model achieved a 30.2% score on the ARC-AGI-3 benchmark, outpacing GPT‑5.6 Sol.

- Claude Opus 5 claims near‑Fable 5 performance with half the token cost.
- Achieved a 30.2% score on the ARC‑AGI‑3 benchmark, far surpassing GPT‑5.6 Sol.
- Leads coding and knowledge‑work benchmarks, indicating strong developer utility.
Anthropic announced its new flagship language model, Claude Opus 5, positioning it as a cost‑effective alternative to the high‑performing Fable 5 system. The company says the model delivers comparable results while requiring roughly half the token consumption, which could lower inference costs for users.
In benchmark testing, Opus 5 recorded a 30.2% score on the ARC‑AGI‑3 suite, a metric designed to evaluate novel problem‑solving abilities. This score is nearly four times higher than the reported performance of GPT‑5.6 Sol on the same test.
The model also topped coding and knowledge‑work evaluations, suggesting it may be well suited for developer tools, code generation, and enterprise knowledge‑base applications. Anthropic highlighted the token‑price advantage as a key differentiator for businesses seeking scalable AI solutions.
Lower token costs can reduce expenses for code‑generation and AI‑assisted development tools.
