Training a Rust 1.5B Coder LM with Reinforcement Learning (GRPO)

DeepSeek-R1 flips the script on training LLMs. Armed with GRPO, it challenges the industry heavies like OpenAI's o1 by playing smart with custom data and cleverly designed rewards. Imagine this: a humble 1.5B model, running on merely a single H100, clocks in at an 80% build pass rate. It’s nibbling at the heels of those bulkier models. GRPO hands the reins to budget-conscious developers, opening up a sandbox where creativity and innovation reign.
