A diffusion language model with delete and insert tokens nearly doubled its tool-calling score

inclusionAI’s LLaDA2.2-mini reached 47.68 per cent on BFCL v4 function calling, up from 25.05 per cent for LLaDA2.0-mini. It runs 1.4B active parameters against 16B total, over 256 experts. DELETE and INSERT control tokens let it rewrite spans in place rather than decode strictly left to right, and it ships Apache-2.0.
