Kimi K3 (Max) takes the top spot on Arena’s new full-stack coding benchmark, ahead of GPT-5.6 Sol (xHigh) and Claude Fable 5.
The benchmark goes beyond code snippets and asks models to build working web apps end to end. It evaluates whether models can plan the build, edit files, run commands, connect databases, handle authentication and APIs, and produce a deployable application.
Human judges then compare the apps for functionality, usability, and how closely they match the requested behavior. The result suggests Kimi K3 is currently stronger at coordinated full-build execution than its rivals on this test.
