Libraries

How to use AdithyaSK/data-agent-4b-normal-best with Transformers:

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

pipe = pipeline("text-generation", model="AdithyaSK/data-agent-4b-normal-best")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("AdithyaSK/data-agent-4b-normal-best")
model = AutoModelForMultimodalLM.from_pretrained("AdithyaSK/data-agent-4b-normal-best", device_map="auto")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
inputs = processor.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(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

data-agent-4b-normal-best (v0)

A 4B data-science agent finetuned from Qwen/Qwen3.5-4B with GRPO (online RL) to solve data-analysis tasks in a sandboxed bash environment. This repo holds the best-eval checkpoint (peak pass@4, step 200) of the 4b-normal run.

Training

Method: GRPO (Group Relative Policy Optimization) via TRL.
Environment: Harbor task spec + E2B cloud sandboxes; single bash tool, answer submitted to /workdir/answer.txt.
Dataset: AdithyaSK/data_agent_rl_environment_train.
Schedule: 1 epoch (1119 steps), 8 generations/prompt, KL-anchored to the reference. Tasks were presented in random order (standard).
This checkpoint: step 200 (best-eval).

Evaluation

Agentic pass@k on the held-out data_agent_rl_environment_eval suite (366 tasks, 4 samples/task, unbiased estimator):

metric	base (Qwen3.5-4B)	this model	Δ
pass@1	0.600	0.660	+0.060
pass@2	0.677	0.745	+0.068
pass@3	0.715	0.779	+0.064
pass@4	0.740	0.802	+0.062

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer
m = AutoModelForCausalLM.from_pretrained("AdithyaSK/data-agent-4b-normal-best", revision="v0", torch_dtype="bfloat16")
tok = AutoTokenizer.from_pretrained("AdithyaSK/data-agent-4b-normal-best", revision="v0")

Part of the data-agent v0 release. Served non-thinking with a single bash tool (Qwen tool-calling).
