H2O-Lightning-31B is a 31B-parameter decision model from H2O.ai, built on google/gemma-4-31B-it. It answers typed decision questions about a record (a document, a ticket, a policy, a conversation), and about images that come with the record. It returns a - yes/no (noul): gives the probability that a statement is true. - #1 of 167 — Intelligence (open and API models within the board's cost and speed caps), JevBench board release v1.6.39, 2026-10-22; ahead of Chon-1.0-12B (79.86) (details) - #2 of 196 — Composite (open-weight models; behind only our H2O-Lightning-4B), JevBench board release v1.6.39, 2026-10-22; ahead of Torchcast Decision 4B (73.03) (details) - #1 of 65 — Capability (all…

Gemma is a family of open models built by Google DeepMind. Gemma 4 models are multimodal, handling text and image input (with audio supported on E2B, E4B, and 12B) and generating text output. This release includes open-weights models in both pre-trained and instruction-tuned variants. Gemma 4 features a context window of up to 256K tokens and maintains multilingual support in over 140 languages. Featuring both Dense and Mixture-of-Experts (MoE) architectures, Gemma 4 is well-suited for tasks like text generation, coding, and reasoning. The models are available in five distinct sizes: E2B, E4B, 12B, 26B A4B, and 31B. Their diverse sizes make them deployable in environments ranging from…

Quantized version of Ateron/Gemma-4-Writers-31B. Offline-quantized W8A16 FP8 in the float-quantized format: weights in float8e4m3fn with per-output-channel symmetric scales, activations kept in bf16/fp16. For each linear layer, every output row gets its own scale starting from amax / 448, refined by an MSE clip search over ~9 clip fractions (0.8–1.0× amax) picking the lowest-error scale per row. Weights are then quantized q = e4m3(w / scale) with round-to-nearest and saturation. This per-channel + clipping scheme gives better SNR than vLLM's online per-tensor --quantization fp8 path. Only 2D linear projection weights are quantized (attention q/k/v/o, MLP gate/up/down). Embeddings, norms…
