Anthropic Releases Claude Sonnet 4.5: Top Coding and Computer-Use Model with Agent SDK
Anthropic has released Claude Sonnet 4.5, claiming it is the best coding model and strongest model for building complex agents, with a 61.4% score on OSWorld (up from 42.2% for Sonnet 4) and state-of-the-art performance on SWE-bench Verified. The release is accompanied by major product upgrades including checkpoints in Claude Code, a native VS Code extension, a Claude Agent SDK giving developers access to the same infrastructure powering Claude Code, and new context editing and memory tools in the Claude API. Pricing is unchanged from Sonnet 4 at $3/$15 per million input/output tokens. Early enterprise customers including Cursor, GitHub Copilot, Devin, Canva, and Figma report significant gains in coding, agentic, and long-context tasks.
Anthropic Launches Claude Haiku 4.5: Near-Frontier Performance at $1/$5 per Million Tokens
Anthropic has released Claude Haiku 4.5, a small model priced at $1/$5 per million input/output tokens that delivers coding performance comparable to Claude Sonnet 4 at one-third the cost and more than twice the speed. The model surpasses Sonnet 4 on computer use tasks and achieves 90% of Sonnet 4.5's performance on agentic coding evaluations, running 4-5x faster than Sonnet 4.5. Notably, Haiku 4.5 is classified under ASL-2 safety standards—less restrictive than the ASL-3 applied to Sonnet 4.5 and Opus 4.1—and is described as Anthropic's safest model by automated alignment metrics. It is available via the Claude API, Amazon Bedrock, and Google Cloud Vertex AI.
