Summary
Prime-rl adds a first-class algorithms layer with six built-in RL algorithms (GRPO, MaxRL, OPD, OPSD, SFT, ECHO), making it easier to implement custom algorithms with a single file.

We spend a lot of time designing an elegant algorithm api in prime rl that expressive and extensible but doesn’t sacrifice on performance
Prime Intellect (@PrimeIntellect): Today, prime-rl gets a first-class Algorithms layer — the first step toward making it the most expressive RL codebase.
Six algorithms ship built-in: GRPO, MaxRL, OPD, OPSD, SFT, and ECHO.
Bringing your own algorithm is writing one file, not rewriting trainer internals.
