Groot-280B-A16B-261023

Groot is a family of open-weight reasoning models from GrootTeam, listed on Hugging Face in four sizes (19B-A3B, 65B-A6B, 238B-A18B and 280B-A16B), all created on 23 October 2026. Only the 280B-A16B model card is detailed in the page. It is a natively multimodal mixture-of-experts model with 280B total and about 16B active parameters per token, a 1M-token context and adjustable reasoning effort (1 to 100). It starts from DeepSeek-V4.1-Flash-1017 and is tuned for reasoning and tool use. The card reports a 16-benchmark average of 58.85, against 58.78 for GLM-5.3-Flash and 55.25 for DeepSeek-V4-Flash-0731, and on DeepSWE 1.1 64.2% pass@1 at about $0.13 per task, against 63% at $0.24 and 53% at $0.46 for those two models. These figures are the team's own, run at maximum reasoning effort. Architecture: 192 routed experts plus one shared, 6 routed experts active per token, plus a 197B-parameter Engram lookup memory and multi-token-prediction draft layers. The card lists an MIT licence tag, with the licence link pointing to DeepSeek-V4.1-Flash-1017. Weights come as FP8 with FP4 experts (365.8 GB) and GGUF UD-Q4_K_XL (356.2 GB), and the 1M context is said to fit on GPU on 4x 96GB cards.
