Plan-and-Act Actor 70B

This is the Actor (Executor) model used in the Plan-and-Act framework from the paper:
Plan-and-Act: Improving Planning of Agents for Long-Horizon Tasks
Code: https://github.com/SqueezeAILab/plan-and-act

The Actor maps observations and plan steps into low-level actions for task execution.

Usage

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model_id = "xTRam1/plan-and-act-actor-70b"
tok = 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 = "Obs: 'Flight search page loaded'. Plan step: 'Enter departure city: SFO'. Predict the next action."
inputs = tok(prompt, return_tensors="pt").to(model.device)
out = model.generate(**inputs, max_new_tokens=256)
print(tok.decode(out[0], skip_special_tokens=True))
