Anthropic announced in February 2025 that they had developed the first hybrid reasoning model in the literature.

They also introduced Claude Code, a command line tool for developers.
This is a super development, but we already have reasoning models like OpenAI o3 mini, DeepSeek-R1, Gemini 2.0 Flash Thinking. This is not a new technology.
But Anthropic’s claim is that it has a different philosophy than other reasoning models on the market.
The philosophy of the hybrid approach of the Claude 3.7 Sonnet is based on the fact that the act of reasoning takes place in a single version, rather than in different versions like other models.
They argue that reasoning should be an integrated capability into existing LLM models, just as humans use a single brain for quick reactions and deep thinking. They argue that this hybrid approach will improve the user experience.
