I find this new model at HF:

"Built for demanding work. A 262 144-token context window, adjustable reasoning effort, tool calling, and text, image and video understanding.

Architecture

Agnes-3.0-Flash is a hybrid-attention decoder: three of every four layers run a gated delta rule (recurrent, with per-layer state independent of sequence length), and the fourth runs standard global attention. Only 18 of the 72 layers therefore hold a KV cache that grows with context."

|Context length|262 144 tokens|
|:-|:-|
|Decoder layers|72 = 54 delta-rule recurrent + 18 global attention, alternating 3 : 1|
|Hidden size|5120|
|Global attention|24 query heads / 4 KV heads (6 : 1 GQA), head dim 256; RMS-norm on q and k, sigmoid-gated output|
|Delta-rule layers|16 key heads / 48 value heads, head dim 128; causal conv (kernel 4) in front, gated RMS-norm; recurrent state in fp32|
|Feed-forward|SwiGLU, intermediate size 17408; plus a parallel SwiGLU 2048 branch in every layer|
|Positions|3-axis rotary (text / height / width), interleaved mrope sections 11 : 11 : 10, base 1e7, applied to the first 25 % of each head dim (64 dims)|

Edit: AA shows its 'Proprietary model'. The name is same as at HF but benchmarks results and context are different. So maybe it's not same model - https://artificialanalysis.ai/models/agnes-3-0-flash

Edit2: As they edit readme at HF to clarify: both models are totally different and AA score isn't correct for HF model (I can't edit title post to remove it tho).
