What it is

Ornith's open-weight mixture-of-experts vision-language model, MIT (card frontmatter license: mit; LICENSE at https://huggingface.co/ornith-ai/Ornith-1.5-122B/blob/main/LICENSE). The download is not gated. The card says "122B MOE". Hugging Face safetensors metadata lists 125,086,497,008 parameters, all BF16. 125.09B is that count to two decimals, so this row stores 125.09 and paramsEstimated is false. The card does not state how many parameters are active. Community posts that say about 10B active are unverified and are not stored. Config: Qwen3_5MoeForConditionalGeneration, model_type qwen3_5_moe. 48 layers, 12 full_attention and 36 linear_attention (full_attention_interval 4), so the full-attention share is 12/48. Hidden size 3072. 32 attention heads, 2 KV heads, head dim 256, vocab 248,320. 256 experts, 8 routed per token, moe intermediate size 1024, shared expert intermediate size 1024. Linear-attention layers are stored with a sliding window of 0 so this formula gives them no token KV. The KV figure uses only the 12 full-attention layers and is an FP16 estimate. Config max_position_embeddings is 262,144. The card says YaRN with a scaling factor of 4 grows that window to roughly 1M tokens; this catalog uses 262,144. Text, image and video in, text out. The card's example reads a <think> trace from reasoning_content. Public launch 20 Oct 2026: https://x.com/ornith_/status/2112553477457268799. Hugging Face lists the repo as created on 16 Oct 2026. Speed is not estimated: the formula streams every weight and understates sparse MoE, and no speed figure is stored.
