Ornith 1.0 397B — Hardware Requirements & GPU Compatibility

ChatFunctions

Ornith-1.0-397B is a Mixture-of-Experts model from Deep Reinforce, the largest member of the original Ornith family, built for agentic coding. It was post-trained on top of Google's Gemma 4 and Alibaba's Qwen3.5 using a self-improving reinforcement-learning framework that learns to generate not just solution rollouts but the scaffolding that drives them, aiming for better search trajectories on tasks like terminal use and repository-scale software engineering. It supports a 262,144-token context window and is released under the MIT license, described by its publisher as globally accessible with no regional limits. At roughly 397 billion parameters, 4-bit quantization needs around 228GB of memory, putting local use in server or multi-GPU territory.

Frequently Asked Questions

How much VRAM does Ornith 1.0 397B need?

Ornith 1.0 397B requires 238.5 GB of VRAM at Q4_K_M, or 794.0 GB at BF16. Full 262K context adds up to 3.9 GB (242.4 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 396.8B × 4.8 bits ÷ 8 = 238.1 GB

KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.

KV Cache + Overhead ≈ 4.3 GB (at full 262K context)

Can I run Ornith 1.0 397B on a Mac?

Yes — Mac Pro M2 Ultra (128 GB) and 14 other Macs can run Ornith 1.0 397B, the smallest at IQ2_XS. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 238.5 GB of usable unified memory (RAM minus macOS overhead), from Mac Studio (M3 Ultra, 256GB).

Can I run Ornith 1.0 397B locally?

Yes — Ornith 1.0 397B can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Ornith 1.0 397B?

At Q4_K_M, Ornith 1.0 397B can reach ~70 tok/s on AMD Instinct MI350X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = 1000 ÷ (active GB ÷ (bandwidth GB/s × efficiency) × 1000 + layers × routing ms)

Mixture-of-Experts: just the active experts get read for each token, along with a fixed routing cost per layer.

Example: NVIDIA B300 → 10.7 GB active ÷ (8000 × 0.65) = 2.06 ms, plus 60 layers × 0.055 ms = 3.30 ms, so 1000 ÷ 5.36 ms = ~187 tok/s

Estimated speed at Q4_K_M (238.5 GB)
