IBM's Granite 4.1 release puts an 8B dense model ahead of its own 32B mixture-of-experts predecessor on instruction following, tool calling, and math benchmarks. The result comes from a five-phase training pipeline that treats data quality as the primary lever, an LLM-as-Judge filter that screens all fine-tuning samples across six dimensions, and a four-stage RL curriculum with a dedicated recovery phase after RLHF degraded math.
