# Anura R1 Ultra

**Anura R1 Ultra** is an agentic coding model by **Genysis IQ** (version 1.0.0).

- Agentic software engineering: reads and edits code, runs commands and tests, plans multi-step work
- Web search and crawling for current information, with cited sources
- Vision: screenshots, diagrams, UI mockups, charts and photos
- Fast local inference on Apple Silicon with MLX (mixture-of-experts, ~3B active parameters per token)
- 128K-token context in the default engine configuration

## Results (measured on an Apple M5, 32 GB)

| | Anura R1 Ultra |
|---|---|
| Identity, held-out questions (Anura system prompt / served with identity preamble) | 26/26 · 26/26 |
| Identity, bare weights under a generic third-party prompt | 24/26 |
| Vision (shapes, OCR, code screenshot, chart, UI→HTML) | 5/5 |
| Agent coding tasks, pass@1, 40 verified tasks in 6 languages | 36/40 |
| Decode speed | ~48 tok/s |
| Cached follow-up prefill (14.7K-token prompt) | 0.18 s |

The coding tasks are the suite the training trajectories came from, so they show the fine-tune kept the
foundation's skills; they are not a held-out benchmark.

## Format

MLX 4-bit weights plus the Anura R1 Ultra LoRA adapter in `anura_adapter/`, applied at load time. The chat
template is Anura R1 Ultra's own (`chat_template.jinja`). About 20 GB of memory is needed (32 GB Apple
Silicon Mac recommended).

## Running it

The intended runtime is the Anura engine and CLI from Genysis IQ (`anura serve`, `anura`), which adds the
agent tools, sessions, web UI and an OpenAI-compatible API. To load the weights directly with mlx-vlm:

```python
from mlx_vlm import load, generate

model, processor = load("<this repo>", adapter_path="<this repo>/anura_adapter")
```
