# MonarchSLM

A Monarch Mixer decoder-only model (sub-quadratic sequence mixing, RMSNorm, SwiGLU) trained on classical philosophy texts, implemented in Julia with Lux.jl. Serves an OpenAI-compatible API with streaming support.

## Endpoints

- `GET /` — Health check and model info
- `GET /v1/models` — List available models
- `POST /v1/chat/completions` — Generate text (supports streaming, top-k, top-p)

## Usage

```bash
# Non-streaming
curl -X POST https://your-space.hf.space/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{"messages": [{"role": "user", "content": "the nature of"}], "max_tokens": 200}'

# Streaming
curl -X POST https://your-space.hf.space/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{"messages": [{"role": "user", "content": "the nature of"}], "stream": true, "temperature": 0.7, "top_k": 40}'
```

## Architecture

- **Model**: ~5M params, 256d embed, 8 layers, 8 Monarch heads
- **Sequence mixing**: Multi-head Monarch Matrix (sub-quadratic) + Causal Depthwise Conv + Learned Gate
- **Tokenizer**: BPE (2000 tokens)
- **Framework**: Lux.jl (explicit parameter/state management)
- **Normalization**: RMSNorm (pre-norm)
- **Feed-forward**: SwiGLU activation
- **Weight tying**: Shared embedding/output projection
- **Inference**: CPU-only, no Lux dependency at runtime (pure NNlib)

## Environment Variables

- `HF_REPO` — HuggingFace model repo (default: `LisaMegaWatts/MonarchSLM`)
- `PORT` — Server port (default: `7860`)
