Battle-test AI coding models side by side
Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
Watch models construct web apps and websites live, so you can see process and output, not just the final file.
Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
Track which coding models accumulate the most wins over time to identify consistently strong performers.
Research lab training models that reason and coordinate over long horizons
Trains models that can communicate and coordinate as a team, with collective rather than individual reward signals.
Explores cooperative AI behaviour and safe scaling through multi-agent experiments and environment design.
Publishes model series and research artefacts so the wider community can build on the work.
Benchmarks that measure whether models stay coherent as situations change over long horizons.
