# Flatbot-micro-4M

**Try it online:** https://chat.flatseek.io

Flatbot-micro-4M is the flagship demonstration model for **Flatseek**.

It is a compact conversational language model trained entirely from scratch using the Flatseek ecosystem. Rather than competing with large language models, Flatbot demonstrates the complete lifecycle of building an AI model—from dataset creation and tokenizer training to transformer training, checkpoint export, and inference.

Powered by a **4.1M-parameter** language model in just **20 MB**, Flatbot was trained from scratch on approximately **2,500 conversational examples**, built with **FlatBuild**, and served by **FlatRun**.

> **Experimental model:** Expect occasional hallucinations, factual errors, and inconsistent responses. Flatbot is intended for learning, experimentation, and showcasing the Flatseek ecosystem rather than production use.

```

### FlatRun Inference

```bash
pip install flatrun
flatrun chat --model flatbot-micro-4M.gguf --temp 0.2
```

```text

## Purpose

Flatbot-micro-4M demonstrates the complete Flatseek pipeline:

1. Build a dataset
2. Train a tokenizer
3. Configure a transformer
4. Train from scratch
5. Export checkpoints
6. Convert to GGUF
7. Run inference with FlatRun

The entire workflow is reproducible on consumer hardware and is designed for education, experimentation, and research.

## Limitations

Flatbot-micro-4M is a compact language model trained on a relatively small dataset. Compared with modern large language models, it has limited factual knowledge, reasoning ability, and context capacity. Its primary purpose is to demonstrate an end-to-end open-source training and inference pipeline, not to serve as a production-grade AI assistant.
