Anthropic launches Claude Sonnet 5 as a low‑cost AI agent model

Anthropic has announced the release of Claude Sonnet 5, a new large‑language model that expands the company’s lineup with enhanced agentic capabilities, lower pricing, and strengthened safety features. The update positions Sonnet 5 as a cost‑effective alternative to leading competitors such as OpenAI’s Opus, GPT‑5.5, and Google’s Gemini Pro, offering businesses a more affordable option for advanced AI applications.

The model’s agentic improvements allow it to execute multi‑step tasks, maintain context over longer interactions, and manage more complex workflows than its predecessor. Anthropic has also reduced the per‑token cost, making the service more accessible for smaller enterprises and developers. In addition, the company has integrated new safety mitigations that aim to reduce hallucinations and mitigate bias, addressing concerns that have plagued earlier iterations.

With Claude Sonnet 5, Anthropic broadens its competitive stance in the AI market, providing a lower‑priced yet capable alternative to the high‑end offerings from OpenAI and Google. The launch underscores the company’s strategy to balance performance, affordability, and responsible AI deployment.
