Anthropic Releases Claude Opus 5

On July 25, Anthropic officially released Claude Opus 5. Positioned as a more thoughtful and proactive frontier model, it is primarily designed for complex tasks. The model achieves a new SOTA across multiple programming and knowledge work benchmarks, with overall intelligence approaching that of Fable 5, but at only half the token cost. It is now available on the paid tier.

Confirmed

* **Model Positioning**: Claude Opus 5 is described as a more "thoughtful and proactive" reasoning model tailored for complex tasks.

* **Benchmark Performance**: Both the official announcement and industry observers note that Opus 5 leads on most benchmarks, particularly in coding and agentic capabilities, achieving a new SOTA.

* **Pricing Strategy**: While delivering frontier-level intelligence on par with Fable 5, Opus 5 is priced at just half the token cost of Fable 5 (some early posts mentioned pricing identical to Opus 4.8).

* **Availability**: The new model is now available on the paid tier.

Why It Matters

The release of Opus 5 signals a more aggressive cost strategy by Anthropic in the frontier model market. By combining top-tier benchmark performance with halved token prices, the model directly challenges competitors' pricing models and is poised to lower the barrier to entry for developers and enterprises tackling complex coding and multi-step agentic tasks.
