The OpenAI o3-mini is a high-speed, cost-effective reasoning model designed for STEM applications, with strong performance in science, mathematics, and coding. Launched in January 2025, it includes essential developer features such as function calling, structured outputs, and developer messages. The model offers three reasoning effort levels—low, medium, and high—allowing users to optimize between deeper analysis and faster response times. Unlike the o3 model, it lacks vision capabilities. Initially available to select developers in API usage tiers 3-5, it can be accessed via the Chat Completions API, Assistants API, and Batch API.
Claude 3.7 Sonnet is Anthropic's most advanced AI model yet and the first hybrid reasoning system on the market. It offers both standard and extended thinking modes, with the latter providing transparent, step-by-step reasoning. The model demonstrates significant improvements in coding and front-end web development, achieving state-of-the-art results on SWE-bench Verified and TAU-bench. Available via Claude.ai, the Anthropic API, Amazon Bedrock, and Google Cloud's Vertex AI, it sets a new standard for intelligent AI-powered problem-solving.
