"On Monday, Anthropic launched a new frontier model called Claude Sonnet 4.5, which it claims will state-of-the-art on coding benchmarks. The company says Claude Sonnet 4.5 is capable of building "production-ready" applications, a leap in reliability from previous AI models. Claude Sonnet 4.5 will be available via the Claude API and in the Claude.ai chatbot. The pricing for developers is the same as Claude Sonnet 4: $3 per million input tokens (roughly 750,000 words, or more than the entire Lord of The Rings series) and $15 per million output tokens."
"In the last year, Anthropic's AI models have emerged as a favorite among developers and enterprises, in large part due to their strong performance on software engineering tasks. Apple and Meta reportedly use Claude AI models internally, and Anthropic has made a significant business selling API access to AI coding applications such as Cursor, Windsurf, and Replit. Recently, OpenAI's GPT-5 has challenged Anthropic's dominance in the space, outperforming Claude models on a variety of coding benchmarks."
"Hershey says he's seen Claude Sonnet 4.5 code autonomously for up to 30 hours during early trials with some enterprise customers. In that time, he watched the AI model not only build an application, but stand up database services, purchase domain names, and perform a SOC 2 audit to make sure the product was secure."
Claude Sonnet 4.5 is a new frontier model released by Anthropic that claims state-of-the-art coding benchmark performance and the ability to build production-ready applications. The model will be available through the Claude API and the Claude.ai chatbot at the same developer pricing as Sonnet 4: $3 per million input tokens and $15 per million output tokens. Anthropic highlights strong enterprise adoption, citing internal use at large companies and API partnerships with coding tools. Competitors like OpenAI's GPT-5 have recently outperformed Claude models on some coding benchmarks. Early trials reportedly showed autonomous multi-day coding, system setup, domain purchases, and SOC 2 audit steps.
