H2O-Lightning-4B

H2O.ai's multimodal decision family: the 4B on Qwen3.5 (text plus record images, one pass per decision, runs on unmodified vLLM behind a stdlib shim, Apache 2.0) and the 31B on Gemma-4-31B-it (v1.3.0, FP8, one-engine overlay) that ranks #4 on JevBench v1.8's open capability view (84.3, I 79.3), #7 official, and #9 on the Decision Index's Nov 6 draw — note the 31B's license turned gated-custom in November (the 4B stays Apache). The 4B topped the v1.6.1 composite when the board held 76 systems; the family has stayed top-ten through every reshuffle since. Live ZeroGPU demo on HF Spaces.
