Intended Use

Qwen3-32B-ABC is intended for:

• Agent-style instruction following for backend development tasks
• Code editing / patch generation in real repositories
• Command-line oriented debugging and step-by-step problem solving
• Research on automated software engineering and agent evaluation

Usage

Transformers (Python)

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model_id = "OpenMOSS-Team/Qwen3-32B-ABC"

tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto",
    trust_remote_code=True,
)

prompt = "Write a FastAPI endpoint that returns health status as JSON."
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)

with torch.no_grad():
    output = model.generate(
        **inputs,
        max_new_tokens=256,
        do_sample=True,
        temperature=0.7,
        top_p=0.9,
    )

print(tokenizer.decode(output[0], skip_special_tokens=True))
