Libraries

How to use open-thoughts/OpenThinkerAgent-32B-SFT-100K with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="open-thoughts/OpenThinkerAgent-32B-SFT-100K")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("open-thoughts/OpenThinkerAgent-32B-SFT-100K")
model = AutoModelForCausalLM.from_pretrained("open-thoughts/OpenThinkerAgent-32B-SFT-100K")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

OpenThinkerAgent-32B-SFT-100K

OpenThoughts-Agent is an open-source effort to curate the best datasets for training agents. Our release includes datasets, models and our research codebase.

OpenThinkerAgent-32B-SFT-100K is post-trained from Qwen/Qwen3-32B with full-parameter SFT on the 100,000-example OpenThoughts-Agent-SFT-100K dataset (Top-4 task sources, GLM-4.7-AWQ teacher in the terminus-2 harness, ≥5-turn trace filter).

Homepage: https://www.openthoughts.ai/blog/agent
Repository: https://github.com/open-thoughts/OpenThoughts-Agent

Performance

Evaluated in the terminus-2 harness (pass@1, mean over 3 stochastic re-runs):

Model	Harness	SWE-Bench-Verified-100	OpenThoughts-TBLite	Terminal-Bench 2.0
Qwen/Qwen3-32B	Terminus-2	26.7	13.7	7.5
OpenThinkerAgent-32B-SFT-100K	Terminus-2	55.7	41.3	26.2

Data

The model is trained on OpenThoughts-Agent-SFT-100K: (task, agent-trajectory) pairs from the Top-4 task sources (SWE-Smith, StackExchange-SuperUser, StackExchange-Tezos with synthetic augmentation, IssueTasks). Trajectories are generated by GLM-4.7-AWQ in the terminus-2 harness and filtered to traces with at least 5 model turns.

Training hyperparameters

learning_rate: 4e-05
lr_scheduler_type: cosine, warmup_ratio 0.1
global_batch_size: 96
num_epochs: 5
cutoff_len: 32768
precision: bf16, DeepSpeed ZeRO-3
