A browser chat demo for DeepSmolLM3-3B, a 3B-parameter reasoning model, that shows the model's long thinking apart from its answer. For anyone who wants to try a small reasoning model without an API key. DeepSmolLM3 3B Chat is a kit in the Developer category, listed by Mindket. It is free. This is version 1, last updated on 2026-11-12. Download it on this page, a zip of its files. Nothing in it runs by itself. Made by Oxygen-Low ## About ### What it is DeepSmolLM3 3B Chat is a chat demo for DeepSmolLM3-3B from Oxygen-Low, a reasoning model with 3B parameters. The model was fine-tuned from HuggingFaceTB's SmolLM3-3B on the Jackrong/DeepSeek-V4-Pro-Distilled-200K dataset. You talk to it in the browser, and its long reasoning appears apart from the answer. ### Who it suits It suits people who want to watch a small reasoning model work through a problem. Who might use this demo | Industry | Who uses it | How they use it | Example | | --- | --- | --- | --- | | Machine learning | Researchers | Read the reasoning a 3B model produces | Ask a logic puzzle and read the thinking shown apart from the answer | | Software | Developers | Test how sampling settings change replies | Raise the temperature and compare two answers | | Education | Students | See a model work through a problem step by step | Ask for a maths check and follow the reasoning | If you need a hosted API for your own app, you can skip it, since this is a chat page. ### Where to use it You can use it online or run a copy yourself. - Web browser: the Space's page on Hugging Face, with no API key needed - Windows, macOS or Linux: a local copy that runs with Python - Hugging Face Spaces: where the hosted chat runs, on ZeroGPU What the demo is good for | Use case | Who | What they get back | | --- | --- | --- | | Chat with a reasoning model | Anyone curious | Replies with the thinking shown separately from the answer | | Tune generation settings | Researchers | Replies shaped by system prompt, length, temperature and top-p | | Compare thinking on and off | Developers | The same question answered with and without extended reasoning | ### How to set it up The hosted chat needs nothing. A local copy needs Python and pip. - Python, with pip - The Python packages that requirements.txt lists 1. Install the huggingface\_hub package. 2. Download the Space's files into a folder. 3. Move into that folder. 4. Install Gradio 6.5.1. 5. Install the packages from requirements.txt. 6. Start the app with Python. ```sh pip install -U huggingface_hub hf download Oxygen-Low/DeepSmolLM3-3B --repo-type space --local-dir DeepSmolLM3-3B cd DeepSmolLM3-3B pip install gradio==6.5.1 pip install -r requirements.txt python app.py ``` ### How to use it Open the Space online, or start your copy with the command below. Then type a message, watch the reply stream in, and adjust the settings when you want a different result. ```sh python app.py ``` The controls you will use | Tool | What it does | | --- | --- | | Thinking mode toggle | Turns the model's reasoning on or off | | /think | Asks for extended thinking, and the long reasoning is displayed in its own place | | System prompt | Replaces SmolLM3's built-in reasoning instructions when you fill it in | | Output length | Sets how long a reply can be, up to 8192 tokens | | Temperature and top-p | Control how varied the replies are | ### Example You ask, "Is 91 a prime number? Explain your reasoning." The reasoning model works through the question, its long thinking appears apart from the answer, and then the final reply streams in. ### For newcomers and experts If you are new to this, leave the system message empty and ask one question. That way the model uses its own reasoning instructions, and you see how it thinks. If you know the field, this is a 3B model fine-tuned from SmolLM3-3B on a distilled dataset, and the app streams tokens with transformers on ZeroGPU. Filling in a system prompt swaps out SmolLM3's default reasoning instructions, and the model may then answer without thinking first. You type a message → The model reasons at length → The thinking shows apart from the answer → The final reply streams in ### Good to know Thinking is optional, and settings change what you get. - Thinking: you can switch reasoning on or off - System prompt: a custom one can make the model skip its thinking, so leave it empty to keep the reasoning - Length: replies can run up to 8192 tokens - License: apache-2 - Cost to run: no API key is required, and no other paid service is named - Data it reaches: the messages you send, plus the Python packages pip installs from requirements.txt - Not for: keeping the model's reasoning when you use a custom system prompt ## README ````markdown # DeepSmolLM3 3B Chat A browser chat demo for DeepSmolLM3-3B, a 3B-parameter reasoning model, that shows the model's long thinking apart from its answer.
