# Claude AI **Entity class:** Artificial-intelligence model family **Domain:** Artificial intelligence / governance / public knowledge **Maturity:** Developed ## Definition Claude is Anthropic's model family and agent platform. Anthropic's 2026 reporting describes Claude writing a large share of production code and taking the lead on a growing share of internal research-and-development tasks. ## Relationships [[wiki/Anthropic|Anthropic]] · [[wiki/Research Acceleration|Research Acceleration]] · [[wiki/AI Research Automation|AI Research Automation]] · [[wiki/Automated AI Researcher|Automated AI Researcher]] - **Source dossier:** [[research/Why Are We Sprinting Off the AI Cliff - Ezra Klein on Recursive Self-Improvement|Why Are We Sprinting Off the AI Cliff?]] ## Sources and provenance - [Source or authoritative context](https://www.anthropic.com/institute/recursive-self-improvement) — accessed for the October 2026 integration. - [[research/Why Are We Sprinting Off the AI Cliff - Ezra Klein on Recursive Self-Improvement|Why Are We Sprinting Off the AI Cliff?]] — reconciled episode conversion and quotation inventory. ## Evidence boundary Time-sensitive roles, forecasts, model capabilities and incident details remain attributed to the dated sources above. This node records the relationship established by the source corpus and does not convert a forecast or reported event into an independently proven fact. ## Simple Reminders, Quotations, and Thoughts > In February 2025, a tiny fraction of the code added to Anthropic's codebase was written by Claude, but by May 2026 it was over eighty percent. Anthropic also categorized the ways its employees were using Claude for R&D work to make better versions of Claude. An employee could use Claude minimally, as an assistant, as an equal collaborator, or give Claude the lead on a task. A year ago, there were basically no examples of Claude being the lead. By August 2026, Anthropic classified Claude as the lead on twenty-six percent of its R&D tasks. > **— Adapted from Ezra Klein**, *The Ezra Klein Show, September 2026* [[reminders/Scientific Acceleration/Claude Became the Lead on a Quarter of Anthropic Research Tasks by Ezra Klein|Claude Became the Lead on a Quarter of Anthropic Research Tasks by Ezra Klein]]
