Agnes-3.0-Flash Preview

Model version clarification

This repository contains an earlier open-weight Preview checkpoint of Agnes 3.0 Flash. It is distinct from the newer production/API checkpoint listed on Artificial Analysis. The Preview release has 33B parameters and a context window of 262,144 tokens. The production/API model uses a different checkpoint and configuration, with a 1M-token context window. Its benchmark results should not be attributed to the Preview weights released here. This repository was initially published as Agnes-3.0-Flash without the Preview suffix. The model card now explicitly identifies this release as Agnes-3.0-Flash Preview to clarify the distinction between the open-weight release and the production/API model. The specifications and Agnes benchmark results below refer to the Preview checkpoint. Hello! 👋 Today we are introducing Agnes-3.0-Flash Preview, an open-weights multimodal preview model built for people who want flagship-class reasoning without flagship-class hardware. Highlights:

Competitive across core capabilities. Agnes-3.0-Flash Preview posts competitive results across reasoning, coding, and instruction-following evaluations.
Built for demanding work. A 262 144-token context window, adjustable reasoning effort, tool calling, and text, image and video understanding.

Benchmarks

Benchmark scope: The Agnes results in the chart and table below belong to the Agnes-3.0-Flash Preview open-weight checkpoint released in this repository. They are not results for the production/API Agnes 3.0 Flash model listed on Artificial Analysis.

The Agnes-3.0-Flash Preview scores in the chart correspond to the open-weight checkpoint released in this repository. Reference results across contemporary models are shown below. The figures were compiled from different sources, harnesses, and model snapshots and do not constitute a controlled head-to-head comparison.

Higher is better for every row. Header parameter figures mix total and active counts, and harnesses and snapshot dates differ across sources, so treat cross-column comparisons as reference values rather than a controlled head-to-head evaluation.

Architecture

Agnes-3.0-Flash Preview 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)
Vocabulary	248 320
Vision tower	27 layers, hidden 1152, patch 16, 2 × 2 spatial merge, projected to 5120

Quickstart

REMOTE CODE REQUIRED

Agnes-3.0-Flash Preview ships its own model implementation. Always load it with trust_remote_code=True.

Requirements

Tested on transformers 5.12.1. Image and video inputs go through the bundled processor, which needs torchvision.

Transformers

python

from transformers import AutoModelForCausalLM, AutoTokenizerpath = "Agnes-AI/Agnes-3.0-Flash"tok = AutoTokenizer.from_pretrained(path)model = AutoModelForCausalLM.from_pretrained(    path, dtype="bfloat16", device_map="auto", trust_remote_code=True)msgs = [{"role": "user", "content": "请用三句话解释什么是人工智能。"}]ids = tok.apply_chat_template(msgs, add_generation_prompt=True, return_tensors="pt").to(model.device)out = model.generate(ids, max_new_tokens=256)print(tok.decode(out[0][ids.shape[1]:], skip_special_tokens=True))

Images and video

Image and video inputs go through the bundled processor (also remote code):

python

from transformers import AutoProcessorproc = AutoProcessor.from_pretrained(path, trust_remote_code=True)msgs = [{"role": "user", "content": [{"type": "image", "image": "photo.jpg"},                                     {"type": "text", "text": "描述这张图。"}]}]inputs = proc.apply_chat_template(msgs, add_generation_prompt=True, tokenize=True,                                  return_dict=True, return_tensors="pt").to(model.device)out = model.generate(**inputs, max_new_tokens=256)print(proc.batch_decode(out[:, inputs["input_ids"].shape[1]:], skip_special_tokens=True)[0])

Reasoning effort

The chat template exposes three reasoning levels — high (default), medium, low — plus a thinking-off switch:

Tool calling

The chat template renders tool definitions for you. The model emits calls as <tool_call><function=…><parameter=…>, and you feed results back as a tool role message:

python

tools = [{    "type": "function",    "function": {        "name": "get_weather",        "description": "Look up current weather for a city",        "parameters": {            "type": "object",            "properties": {"city": {"type": "string", "description": "City name"}},            "required": ["city"],        },    },}]msgs = [{"role": "user", "content": "What's the weather in Beijing right now?"}]ids = tok.apply_chat_template(msgs, tools=tools, add_generation_prompt=True,                              return_tensors="pt").to(model.device)out = model.generate(ids, max_new_tokens=256)reply = tok.decode(out[0][ids.shape[1]:], skip_special_tokens=True)
# <tool_call>
# <function=get_weather>
# <parameter=city>
# Beijing
# </parameter>
# </function>
# </tool_call>
# run the tool, append the result, generate the final answermsgs += [{"role": "assistant", "content": reply},         {"role": "tool", "content": "Clear, 26°C, light northeasterly wind"}]

Over the OpenAI API pass tools= the same way. The server returns the text above verbatim by default; to get structured tool_calls, configure sglang with a tool-call parser matching this format (likewise a reasoning parser, if you want the thinking span in reasoning_content).

SGLang

serve.sh starts a server from a stock public image, overlaying three files onto the image's sglang package and nothing else. See sglang_patch/README.md.

bash

docker run --gpus all --shm-size 64g -p 30001:8080 \    -v /path/to/agnes-3.0-flash:/model \    lmsysorg/sglang:nightly-dev-20260908-20ca564b \    bash /agnes-3.0-flash/serve.sh --served-model-name Agnes-3.0-Flash

serve.sh forwards extra command-line arguments to sglang, which is how --served-model-name takes effect; --tp 2 works the same way. The server listens on port 8080 inside the container:

python

from openai import OpenAIclient = OpenAI(api_key="EMPTY", base_url="http://localhost:30001/v1")response = client.chat.completions.create(    model="Agnes-3.0-Flash",    messages=[{"role": "user", "content": "Design a fault-tolerant event processing architecture."}],    temperature=1.0,    max_tokens=2000,)print(response.choices[0].message.content)

Pass stream=True for streaming; tools= and reasoning_effort= are accepted the same way.

Hardware Requirements

Resource	Recommendation
GPUs	1 × NVIDIA H200 141 GB or NVIDIA H100 80 GB (or equivalent) at bf16
Tensor parallel	`--tp 1`; `--tp 2` for maximum context and concurrency
Weights on disk	Approximately 66 GB for the bf16 checkpoint
Host memory	128 GB or more recommended

Actual context length and concurrency depend on KV-cache allocation, runtime overhead, and tensor-parallel configuration; validate the target workload on the intended hardware.

Recommended Inference Settings

These are the checkpoint's own generation_config.json defaults.

Model Capabilities

Capability	Support
Advanced reasoning	Yes, with `high` / `medium` / `low` effort levels
Coding and debugging	Yes
Long-context analysis	262 144 tokens
Image understanding	Yes
Video understanding	Yes
Tool calling	Yes (`<tool_call>` / `<tool_response>`)
Streaming	Yes
OpenAI-compatible APIs	Chat Completions via sglang
