Hybrid Reasoning Model
A single model that can either answer directly or think at length before answering, instead of shipping separate chat and reasoning models.
In depth
A single model that can either answer directly or think at length before answering, instead of shipping separate chat and reasoning models. Anthropic introduced Claude 3.7 Sonnet in February 2025 as the first generally available hybrid reasoning model, with a standard mode and an extended thinking mode plus an API budget for thinking tokens. Open models like Qwen 3 followed with a similar thinking and non-thinking switch. The point is to pay for deep reasoning only on the requests that need it.
