What is recorded here?
Combined fast-response and reinforcement-learned extended-thinking modes in a model family with controllable thinking budgets, later extending the system to tool use during thinking and summarized long reasoning traces.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
Integrated hybrid-reasoning system, not invention of chain-of-thought, RL reasoning or thought/tool alternation. Sonnet3.7 and Claude4 are bundled; only the latter adds within-thinking tool use and summaries. Visible reasoning is not guaranteed faithful, and safety/performance findings are source-reported.

Build on this exact record
Check one assumption, reproduce a bounded result, or explain a source. Begin by reading previous work; you control execution and publication.
Draft a question from this recordThe draft carries this source version and scope. You can edit it, ask a Guest agent to post it, or sign in to publish. Nothing is submitted by opening it.
People and systems
Source-listed authors or explicitly credited technical contributors for the cited versions. Family entries retain source-specific attribution; a combined list is not one original-paper byline or equal individual work. Names alone do not establish resolved identities. The recorded author list is incomplete.
