Estimate from the version's published specs, benchmarks and reviews, 0-5; scores are only comparable within one criteria year. Scored as launched (Claude Sonnet 4, 22 May 2025): 200K-token input window (the 1M-token beta came on 12 Aug 2025, after launch); price $3 in / $15 out per 1M tokens = $6 blended at 3:1 (Anthropic, TechCrunch); text and image input. Anthropic: SWE-bench Verified 72.7%; its original Terminal-Bench figure is a different benchmark from Terminal-Bench 4.0, so coding null. Reasoning null (no launch-version AA index opened), speed null (no tokens/s published). Reviews: Zvi, Tom's Guide (7 prompts vs Gemini 2.5 Pro), 16x Engineer, Latent Space AINews; early reactions rather than long-run tests.[3]
Sonnet 4 is probably best in its class for many purposes, and deserves the 4 label because of its agentic aspects but isn't a big leap over 3.7 for other purposes.
Claude 4 Sonnet pulls ahead with its emotional intelligence, creative flair and technical depth.
For most day-to-day coding tasks, Sonnet 4 delivers frontier performance without the premium price, making it the more practical choice for regular development work, replacing the old Claude 3.7 Sonnet.

系统卡仅标注“2025 年 5 月”,因此以发布文章的日期为准:“Claude 4 隆重登场,2025 年 5 月 22 日”——“今天,我们推出下一代 Claude 模型:Claude Opus 4 和 Claude Sonnet 4”;TechCrunch[4] 报道该发布于 Anthropic[3] 开发者大会“周四”(5 月 22 日)进行。
"On May 22, 2025, Anthropic[1][3] released two more models: Claude Sonnet 4 and Claude Opus 4", with a code execution tool, MCP connectors and a Files API for developers; the article's screenshot shows a Claude Sonnet 4 answer.
Anthropic's[1] launch post, dated "May 22, 2025": Sonnet 4 "is a significant upgrade to Claude Sonnet 3.7", free users get it, it scores 72.7% on SWE-bench and costs $3/$15, and GitHub[5] will make it the model behind Copilot's new coding agent. The system card that is the source prints only "May 2025", so this row dates the pin.
TechCrunch, 2025-05-22: Anthropic[1][3] launched Opus 4 and Sonnet 4 "during its inaugural developer conference Thursday"; free and paying users get Sonnet 4, designed as a "drop-in replacement" for Sonnet 3.7, at $3/$15 per million tokens on the API, Bedrock and Vertex AI.
GitHub's changelog of 22 May 2025: Sonnet 4, "the successor to the developer-loved Claude Sonnet 3.7", comes to all paid Copilot plans in Copilot Chat on github.com, VS Code and GitHub Mobile, and "is also coming to agent mode and the coding agent"; Opus 4 is limited to Copilot Enterprise and Pro+.
