this is f*cking insane, Claude Code agents turned a reading list into a lab you can run in your browser Boris Cherny (creator of Claude Code) gave 12 agents 64 research papers and one assignment: build a browser lab where readers can rerun the experiments pick a fluid simulation, change the conditions and watch how the result changes switch methods while keeping the same scene. inspect the equations, code and measurements beside the animation give each group a specific job: → readers extract equations, assumptions and experimental settings → builders turn the methods into runnable code → reviewers compare outputs against the papers → interface agents build the controls for exploring each experiment a simulation can look convincing while producing the wrong answer reviewers check whether it preserves mass, stays stable and matches the paper's measurements before accepting the implementation every experiment has to show: > the claim being tested > the conditions used > the difference from the reference result > the details still needed to verify it the lab covered 11 methods across 28 reference scenes. seven matched the selected reference results within the stated tolerances; four stayed marked for further review give Claude Code your paper collection, then ask: "Turn these papers into an interactive browser lab 1. Extract implementable methods, equations and experimental settings. Attach page references and flag missing details 2. Assign independent methods to separate agents. Use shared inputs and measurement tools so the results can be compared 3. Have reviewers check each implementation against the paper. Record discrepancies and keep unverified results clearly marked 4. Build controls for changing parameters, comparing methods and opening the code behind each result" start with one paper and reproduce one reference experiment before adding more agents include the inputs, dependencies and checks so the next reader can rerun it from a clean checkout watch the agents at work below

Introducing Claude Opus 5.5, the first model in our new Claude 5.5 family. It performs at the level of Claude Fable 5.1 for most tasks, and costs 40% less to run than Opus 5.
