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:

from mlx_vlm import load, generate

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

License and provenance
