KLM 1.5-Chat Preview

Chats with a small 99M-parameter language model in the browser, with an optional reasoning mode, a calculator and live web search. It suits people who want to try a tiny chat model.

About

What it is: This Space is a preview of a chat model with 99M parameters, built on KLM 1.5. You can turn reasoning on or off, and the chat can call a calculator and a web search that brings back live results. The model is small and often wrong, so you should check anything important yourself.

Who it suits: It suits people who want to see what a tiny chat model can do, and how far a calculator and a search tool carry it.

Industry | Who uses it | How they use it | Example
AI research | Researchers studying small models | Try a tiny chat model with and without reasoning | Compare answers with reasoning switched on and off
Education | Teachers and students | Show how tools help a small model | Ask a sum and watch the calculator step in
Software | Developers | Check how a compact model feels in a chat | Read the Gradio app code to see how tools plug in

You can skip it if you need reliable answers, since the source warns that the model is often wrong.

Where to use it: You can use it in these places:

• A browser: open the Space's page on Hugging Face and nothing needs installing.
• Windows, macOS or Linux: run your own copy with Python 3.12.12.

Use case | Who | What they get back
Trying a small chat model | Curious users | Short chat replies from a 99M-parameter model
Math questions | Students | An answer worked out by the calculator tool
Questions needing fresh facts | Anyone testing search | A reply that draws on live search results

How to set it up: You need these first for a local copy:

• Python 3.12.12
• pip

The online page needs none of this. For your own copy, follow the steps below.

1. Install the Hugging Face tools.
2. Download the Space's files into a folder.
3. Move into that folder.
4. Install Gradio at the version the Space uses, then the other packages.
5. Start the app.

pip install -U huggingface_hub
hf download Eclipse-Senpai/KLM-1.5-Chat-Preview --repo-type space --local-dir KLM-1.5-Chat-Preview
cd KLM-1.5-Chat-Preview
pip install gradio==6.30.0
pip install -r requirements.txt
python app.py

How to use it: Open the Space in a browser, or start your own copy with the command below. Then type a message in the chat and choose whether reasoning and the tools are on.

python app.py

Tool | What it does
Reasoning | Can be switched on or off for a reply
Calculator | Works out arithmetic for the model
Web search | Fetches live results the model can use

Example: You ask a question that needs a sum, with the calculator turned on. The chat works out the figure with the tool and answers in a short reply. You still need to check the result.

For newcomers and experts: If you are new to this, open the Space in your browser and ask something simple, like a short sum. Then switch reasoning on and ask the same thing again to see how the reply changes.

If you know the field, this is a 99M-parameter model, tiny next to common chat models, so it trades accuracy for size and speed. The repository holds separate files for a calculator and a search tool, and a chat page. Search results can improve answers, but the model can still get them wrong.

You type a message
The model decides if it needs a tool
Calculator or web search runs
The model writes a reply
You check the answer

Good to know: Its answers can be wrong with search or without it. Check anything important before you rely on it.

• License: apache-2
• Cost to run: none named
• Data it reaches: the web, through the optional search tool that retrieves live results
• Not for: answers you cannot check, since the model is often wrong
