ea-dev-final

This is checkpoint final (step 471) from fine-tuning Qwen/Qwen2.5-3B-Instruct for evaluation agent tasks.

Checkpoint Details

• Checkpoint: final
• Global Step: 471
• Epoch: 3.00
• Training Loss: 0.8296
• Learning Rate: unknown
• Base Model: Qwen2.5-3B-Instruct
• Task: Multi-modal quality assessment with CoT reasoning

Model Description

This checkpoint is from training an evaluation agent that can assess:

• Video Quality: Temporal consistency, motion smoothness, object consistency (VBench)
• Image Quality: Aesthetic quality, semantic alignment, visual fidelity (T2I-CompBench)
• Open-ended Evaluation: Custom quality assessment tasks

The model uses Chain-of-Thought (CoT) reasoning to provide detailed explanations for its evaluations.

Files Included

This checkpoint contains:

• Model Weights: model*.safetensors - The actual model parameters
• Tokenizer: Complete tokenizer configuration and vocabulary
• Configuration: Model and generation configuration files

Note: This checkpoint contains only inference files (no optimizer states).

Usage

For Inference

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

# Load the checkpoint
model = AutoModelForCausalLM.from_pretrained(
    "ea-dev-final",
    torch_dtype=torch.bfloat16,
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained("ea-dev-final")

# Example evaluation prompt
prompt = """Please evaluate the quality of this video based on the following criteria:
1. Visual quality and clarity
2. Temporal consistency
3. Motion smoothness

Video description: A person walking through a park with trees swaying in the wind.

Let me think step by step:"""

inputs = tokenizer(prompt, return_tensors="pt")
with torch.no_grad():
    outputs = model.generate(
        **inputs,
        max_length=512,
        do_sample=True,
        temperature=0.7,
        pad_token_id=tokenizer.eos_token_id
    )

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

Resume Training (if optimizer states included)

# Use with LLaMA-Factory
