Big War in AI: ChatGPT o1-preview, o3-mini, and Claude 3.7 Sonnet - Which is the Best?


As you know, Anthropic announced the new Claude model: Claude 3.7 Sonnet. Developed by Anthropic and released in February 2025, this AI model is the first hybrid reasoning model that combines both general-purpose language processing and logical reasoning capabilities under one roof. Claude 3.7 Sonnet made significant progress with an accuracy rate of 62.3% on SWE-bench Verified, surpassing Claude 3.5 Sonnet's 49.0% rate. Additionally, it achieved higher accuracy rates in tasks related to retail and airlines compared to previous versions. This model is particularly strong in coding and front-end web development. Anthropic also offers a command-line tool called Claude Code, which allows developers to delegate tasks like writing code, testing, and pushing to GitHub. Furthermore, Claude 3.7 Sonnet is designed to better adapt to real-world tasks. It excels in handling complex codebases, planning, and full-stack updates. The model is priced at $3 per million input tokens and $15 per million output tokens, which is more expensive than some competing models.
