Libraries

How to use wckwan/ALFWorld-OLMo-3-7B-Outcome-GRPO with Transformers:

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

pipe = pipeline("text-generation", model="wckwan/ALFWorld-OLMo-3-7B-Outcome-GRPO")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("wckwan/ALFWorld-OLMo-3-7B-Outcome-GRPO")
model = AutoModelForCausalLM.from_pretrained("wckwan/ALFWorld-OLMo-3-7B-Outcome-GRPO", device_map="auto")
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]:]))

ALFWorld-OLMo-3-7B-Outcome-GRPO

A allenai/Olmo-3-7B-Instruct policy trained with GRPO on ALFWorld text-based embodied household tasks, with outcome-only rewards.

The repository root holds the final policy, at training step 400.

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("wckwan/ALFWorld-OLMo-3-7B-Outcome-GRPO")
tokenizer = AutoTokenizer.from_pretrained("wckwan/ALFWorld-OLMo-3-7B-Outcome-GRPO")

# An intermediate checkpoint
model_step = AutoModelForCausalLM.from_pretrained("wckwan/ALFWorld-OLMo-3-7B-Outcome-GRPO", subfolder="step_20")

Raw FSDP checkpoints

fsdp/global_step_<N>/ holds the unmerged verl FSDP checkpoint (sharded fp32 model state, optimizer state and extra state) for step(s) 400. These are for resuming training, not for inference — use the merged exports above to load a policy.
