Performance Metrics

Usage

⚠️ IMPORTANT: This model expects Gemma-3 turn-based prompt format

This model was fine-tuned using Gemma-3's native turn markers. Using the correct format is critical for optimal performance.

Correct Prompt Template:

from transformers import AutoTokenizer, AutoModelForCausalLM
from peft import PeftModel
import torch

# Load model
tokenizer = AutoTokenizer.from_pretrained("google/gemma-3-1b-it")
base_model = AutoModelForCausalLM.from_pretrained(
    "google/gemma-3-1b-it",
    torch_dtype=torch.float16,
    device_map="cuda:0"
)
model = PeftModel.from_pretrained(base_model, "sweelol/chronos-gemma-3-1b-v1")

# Build prompt with Gemma-3 turn markers
prompt = """<start_of_turn>user
Write a horological editorial in the style of A Collected Man based on these specifications.

Technical specifications:
Brand: Rolex, Model: Submariner, Reference: 126610LN, Case Size: 41mm

<end_of_turn>
<start_of_turn>model
"""

# Generate
inputs = tokenizer(prompt, return_tensors="pt").to("cuda")
outputs = model.generate(**inputs, max_new_tokens=500, temperature=0.4, top_p=0.9)
print(tokenizer.decode(outputs[0], skip_special_tokens=False))
