Qwen3-30B-A3B-Thinking-2507-FP8
This repository contains Qwen/Qwen3-30B-A3B-Thinking-2507-FP8
together with a Furiosa Executable Bundle (FXB) for running it on
FuriosaAI RNGD with Furiosa-LLM.
The same model also runs on other frameworks (such as vLLM, SGLang, and
Transformers); for usage with those, see the upstream
Qwen/Qwen3-30B-A3B-Thinking-2507-FP8 model card.
Overview
Qwen3-30B-A3B-Thinking-2507 is the updated (2507) thinking variant of Qwen3-30B-A3B,
an auto-regressive Mixture-of-Experts (MoE) transformer with 30.5B total
parameters of which about 3.3B are activated per token. It operates in thinking
mode only — it produces an internal chain of thought before its final answer —
and offers strong reasoning over text, instruction following, multilingual
coverage, and tool usage. Its intended use is the same as the upstream
Qwen/Qwen3-30B-A3B-Thinking-2507-FP8,
and it is released under the Apache 2.0 License.
- Architecture: Qwen3-MoE (Mixture-of-Experts)
- Input / Output: Text / Text
- Supported Inference Engine: Furiosa LLM
- Supported Hardware: FuriosaAI RNGD
Quantization
Weights are quantized to FP8 (static), following the upstream FP8 release,
and activations use dynamic FP8 quantization at runtime (per-token / per-block).
The KV cache stays in 16-bit precision.
Features
- Reasoning. Qwen3-30B-A3B-Thinking-2507 is a thinking model that always produces a chain of thought before its final answer. Launch the server with the
qwen3 reasoning parser to have Furiosa-LLM parse the reasoning into a separate field (see Basic Usage below).
- Tool calling. The model supports tool (function) calling through the
hermes tool-call parser, the parser used by the Qwen3 series.
Parallelism Strategy
On RNGD, Qwen3-30B-A3B-Thinking-2507-FP8 runs with a tensor-parallel size of
32 PEs, which maps to four RNGD cards (8 PEs per card).
Usage
To run this model with Furiosa-LLM, follow the example commands below after
installing Furiosa-LLM and its prerequisites.
Launch the server
Qwen3-30B-A3B-Thinking-2507-FP8 always reasons. Serve it with the qwen3
reasoning parser so the chain of thought is returned in a separate field:
To also enable tool (function) calling, add the hermes tool-call parser (the
parser used by the Qwen3 series):
When the server is ready, you will see:
Basic Usage
The server exposes an OpenAI-compatible API. You can send a request with curl:
Qwen3-30B-A3B-Thinking-2507-FP8 returns its reasoning separately from the final
answer:
response.choices[].message.reasoning (non-streaming)
response.choices[].delta.reasoning (streaming)
Note: The reasoning field is not part of the OpenAI API specification but
is a widely followed convention (the OpenAI Agents SDK, vLLM, and others). It
appears only in responses that contain reasoning content; accessing it otherwise
raises an AttributeError.
Advanced Usage
Tool calling. With the server launched using
--enable-auto-tool-choice --tool-call-parser hermes (see
Launch the server), pass tools in the request and let the
model decide when to call them. See the
Tool Calling guide
for a complete client example and details on tool-choice options.
