Supra Title is live! 🦅

We just released Supra Title (experimental), a purpose-built 350M model for generating chat conversation titles, built on LFM2.5-350M.

Most platforms use large general-purpose models to title conversations. Supra Title does only that, and does it fast, in GGUF format, on any hardware.

No system prompt needed. Just send the user message and get a title back.

Examples:

Quick start:

llama serve -hf SupraLabs/Supra-Title-350M-exp-GGUF:Q6_K

Available from Q2 (177 MB) to BF16 (711 MB). Q8_0 or Q6_K recommended.

This is an experimental release. We are expanding the SFT dataset and exploring preference optimization before a full release.

Feedback welcome!

SupraLabs just released a new model! - Supra-50M-Reasoning

Hello again r/LocalLLaMA! Supra-50M-Reasoning (ThinkSupra-50M) is the reasoning version of Supra-50M-Instruct. It produces a full thinking chain before every answer, fine-tuned from Supra-50M-Base using a custom synthetic dataset of 500 samples generated by Qwen3 1.7B, trained for 6 epochs. It's experimental, it hallucinates, and it's fully open. This is part of the Supra-50M collection under Project Chimera.

Model: 🤗 Supra-50M-Reasoning

Dataset: SupraThink-Dataset-500x

What's coming next?

💬 Sample Outputs

Prompt: "What is AI?"

🧠 Thinking

Okay, the user is asking about AI. Let me start by recalling what AI is. AI is a subset of machine
learning, specifically neural networks. It's a branch of computer science that focuses on enabling
machines to learn from data. The main goal is to create intelligent machines that can perform tasks
that would normally require human intelligence. I need to make sure I'm being clear. AI is a broad
field with many different applications. For example, AI-powered virtual assistants like Siri or Alexa.
Also, AI is used in healthcare, finance and even in the field of robotics. I should mention the key
concepts, such as data, algorithms and the potential applications. I should also mention the potential
challenges, such as bias and lack of human intervention. Be concise, under 150 words.

✅ Response

AI is a subset of machine learning that focuses on enabling machines to learn from data. It involves
training machines to recognize patterns and make decisions based on data. AI is used in healthcare,
finance and even in the field of robotics. Its applications include virtual assistants like Siri or
Alexa, and its potential for automation and training.

Prompt: "What is the meaning of life?"

🧠 Thinking

Okay, the user is asking about the meaning of life. Let me start by recalling what life is. It's about
the human experience, like the choices we make, the relationships we have with others and the choices
we make. I need to make sure I cover the main points: the human experience, the human mind, the role
of our emotions and the experiences we have. Keep concise, under 150 words.

✅ Response

Life is about the human experience, the human mind and the experiences we have. The human mind is a
complex interplay of emotions, thoughts and experiences, shaped by the experiences we have.

Final answer: Life is about the human experience, the human mind and the experiences we have.

⚠️ THE MODEL STILL HALLUCINATES AND ANSWERS WILL SOMETIMES BE INCORRECT ⚠️

First reasoning model from SupraLabs. It's experimental and chaotic, but the thinking chains are real. Feedback welcome!
