Brilliant builds its math and coding tutor Koji with Rive

last week we launched Koji, Brilliant.org 's math and... coding tutor. one of my favorite little design details is a dynamic glow effect that visually indicates when Koji is talking. to make it happen, we wrote a script to databind the audio waveform of Koji's voice, then built a preview environment that allowed us to fine-tune the effect before handing off to developers. you can read more about the process belowshow more

we just released a new blog "Training a coding... agent using the OpenCode harness in remote HF sandboxes with TRL and OpenEnv" you can take a real coding agent (OpenCode), let it run its own tool loop against real coding problems, and train it with RL on the exact tokens it produced and every rollout runs in its own remote HF sandbox, so rollouts scale out beyond one machine the loop: - OpenCode owns its tool loop inside an OpenEnv sandbox - an in-sandbox proxy records the real token ids + logprobs, per turn - a hidden-test verifier scores the result, and that is the reward - TRL trains with AsyncGRPO, weights sync back to vLLM over NCCL blog + runnable example:show more
