Introducing Supra Title 50M, our latest and most compact chat title generation model. Built on our newest 50M-parameter foundation model, it features an extended context length for its size, enabling stronger input understanding and more accurate title generation. Designed for efficiency, Supra Title 50M delivers fast inference while advancing the capabilities of small language models.
About Model...
Supra Title uses SupraLab's latest foundation model (SupraLabs/Supra-1.5-50M-Base-exp) to power title generation with SupraLab's title dataset (which currently is the world's biggest dataset for chat titles).
The model features an extended 4k context length, making this one of only models that can run seamlessly on a wide range of hardware, ranging from very low-end CPUs to server-grade GPU clusters.
The amazing team at SupraLabs has open-sourced the chat title dataset and the models for finetuning & inference!
| model | repository |
|---|---|
| SupraLabs/supra-title-50m-pre | (this model) |
| SupraLabs/supra-title-50M-pre-gguf | Supra Title 50M GGUF |
We recommend using the Supra Title 50M PREV model for finetuning/RL, and Supra Title 50M GGUF (at Q8) for inference.
Model Generation Samples...
Our model outputs the chat title as the response, reducing complexity!

Devs can use the raw output as the title, which reduces the complexity of JSON or other formats!
Model Inference...
To run our model, you can use the provided code, which automatically downloads the model from HuggingFace.
import os
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
def main():
# Path to your final trained model directory
model_path = "./title-model-final-FINAL"
if not os.path.exists(model_path):
print(f"[!] Error: Model path '{model_path}' does not exist.")
print("Please check your OUTPUT_DIR or copy your trained model here.")
return
print(f"[*] Loading tokenizer from {model_path}...")
tokenizer = AutoTokenizer.from_pretrained(model_path)
print(f"[*] Loading model onto available device...")
model = AutoModelForCausalLM.from_pretrained(
model_path,
torch_dtype=torch.bfloat16,
device_map="auto"
)
model.eval()
print("[+] Model and tokenizer loaded successfully.\n")
print("=" * 60)
print("Chat Title Generator Interactive Loop")
print("Type your message/article below. Type 'exit' or 'quit' to stop.")
print("=" * 60 + "\n")
while True:
try:
user_input = input("User Message > ").strip()
except (KeyboardInterrupt, EOFError):
print("\n[*} Exiting...")
break
if not user_input:
continue
if user_input.lower() in ["exit", "quit"]:
print("[*] Goodbye!")
break
# Format the prompt exactly like during training
prompt = f"User: {user_input}\nTitle: "
# Tokenize inputs
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
# Generate with optimized hyperparameters for concise title generation
with torch.no_grad():
outputs = model.generate(
**inputs,
max_new_tokens=24, # Titles should be very short
do_sample=True, # Enables dynamic sampling
temperature=0.4, # Lower temperature prevents random word drift
top_p=0.85, # Nucleus sampling for high-probability tokens
top_k=40, # Limits vocabulary choices to top 40 candidates
repetition_penalty=1.2, # Hard safety rail against repeating words (like Emanuel Emanuel...)
pad_token_id=tokenizer.pad_token_id,
eos_token_id=tokenizer.eos_token_id
)
# Extract only the newly generated tokens
generated_ids = outputs[0][inputs["input_ids"].shape[1]:]
predicted_title = tokenizer.decode(generated_ids, skip_special_tokens=True).strip()
print(f"Generated Title > {predicted_title}")
print("-" * 60)
if __name__ == "__main__":
main()
With this code, you can run supra-title-50M-pre-gguf in your terminal. After loading in, type your prompt to get chat titles!
Our model works by analyzing the user input that a user sends to an LLM, then generating a 2-4 word title!
We recommend using the current settings, or:
- temp=0.55
- top_K=15
- top_P=0.85
- repitition_penalty=1.35
- max_tok=10
