Anthropic, the AI startup company, has introduced its newest AI model, Claude Sonnet 4.5, which the company says is the “best coding model in the world. “Indeed, great news for the entire developer community. The new model pushes the boundaries in terms of reliability and ease of use. Alongside this, the primary goal is to develop production-ready apps that surpass the capabilities typically achieved by preceding AI systems at the prototype level.
The Claude Sonnet 4.5 is available through the Claude API and Claude chatbot, with pricing similar to that of the Claude Sonnet 4: $3 per million input tokens and $15 per million output tokens. As stated by Anthropic, the launch marks a big leap in coding, reasoning, and real-world business applications.
How Does Claude Sonnet 4.5 Perform?
Regarding the results, they stood out on benchmarks such as SWE-Bench, which measures software coding abilities. The AI company says the new model is smaller than Claude Opus 4.1 but smarter in almost every way. It can also run autonomously for up to 30 hours, compared to seven hours with the Claude Opus 4, which enables it to complete complex, multi-step projects with complete focus.
Enterprises have already shared their trial reviews, wherein Claude Sonnet 4.5 not only helped with writing applications but also set up database services, purchased domain names, and performed a SOC 2 audit to maintain security from the outset.
Here is the official statement of Anthropic mentioned in its blog post focused on both capability and safety:
“Claude Sonnet 4.5 is our most aligned frontier model yet. Claude’s improved capabilities and our extensive safety training have enabled us to enhance the model’s behavior substantially, reducing concerning behaviors such as sycophancy, deception, power-seeking, and the tendency to encourage delusional thinking. “
More than a Model: SDK and Tools
With this significant launch, Anthropic also introduced the Claude Agent SDK, which enables developers to build custom AI agents using the same infrastructure that powers Claude Code. There’s a cut-throat competition in the AI space. Considering this, Anthropic is also taking a step forward with the advancements in its flagship models every month.
Lastly, the company recommends starting to use the Anthropic’s Claude Sonnet 4.5 model, which offers excellent performance at the same price. The AI sector is evolving, and it’s your time to grow with the changing scenarios or updates!
