About Qwen3-Swallow

Qwen3-Swallow is a bilingual Japanese-English large language model developed by the Swallow Project at the Institute of Science Tokyo (formerly Tokyo Institute of Technology) and AIST. Built upon Qwen3 through Continual Pre-Training (CPT), Supervised Fine-Tuning (SFT), and Reinforcement Learning (RL), it achieves strong performance on both Japanese and English tasks while maintaining capabilities in mathematics and coding.

For more details, see the original model card.

Usage

Quick Start (Python)

from mlx_lm import load, generate

model, tokenizer = load("tocchitocchi/Qwen3-Swallow-32B-RL-v0.2-MLX-fp16")

messages = [{"role": "user", "content": "hello"}]
prompt = tokenizer.apply_chat_template(
    messages, add_generation_prompt=True
)

response = generate(model, tokenizer, prompt=prompt, verbose=True, max_tokens=512)

Interactive Chat

mlx_lm.chat --model tocchitocchi/Qwen3-Swallow-32B-RL-v0.2-MLX-fp16

OpenAI-Compatible Server

mlx_lm.server --model tocchitocchi/Qwen3-Swallow-32B-RL-v0.2-MLX-fp16 --port 8080

Then connect with any OpenAI-compatible client at http://localhost:8080/v1.
