Prime Intellect released prime-rl v0.10.0 and verifiers v0.4.0 on October 19, 2026. According to its release information, prime-rl adds the reinforcement learning algorithm IPO and sets it as the default, replacing the previous DPPO-based default loss. In tests comparing Qwen3-235B-A22B SFT against torchtitan, prime-rl achieved a 1.15× speedup (3732 vs 3253 tokens/s/GPU); the MFU of GLM-5.3 full SFT increased from 22.3% to 40.1%. The evaluation CLI has moved from verifiers into prime-rl, and support has been added for models including DeepSeek V4 Flash, Qwen3.8 Flash Next, and Nemotron-H. There are currently no subsequent independent development facts.
