Which GPUs Can Run Ornith 1.0 35B?
Q4_K_M · 21.4 GBOrnith 1.0 35B (Q4_K_M) requires 21.4 GB of VRAM to load the model weights. For comfortable inference with headroom for KV cache and system overhead, 28+ GB is recommended. Using the full 262K context window can add up to 10.7 GB, bringing total usage to 32.1 GB. 7 GPUs can run it, including NVIDIA GeForce RTX 5090.
All compatible consumer-level GPUs are running near their VRAM limit. You may also want to consider professional GPUs (e.g., NVIDIA A100, H100) which offer significantly more VRAM. For more headroom and better throughput, consider a multi-GPU configuration with tensor parallelism (supported by tools like vLLM, llama.cpp, or text-generation-inference).
Which Devices Can Run Ornith 1.0 35B?

Frequently Asked Questions
- How much VRAM does Ornith 1.0 35B need?
Ornith 1.0 35B requires 21.4 GB of VRAM at Q4_K_M, or 70.6 GB at BF16. Full 262K context adds up to 10.7 GB (32.1 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 35.1B × 4.8 bits ÷ 8 = 21.1 GB
KV Cache + Overhead ≈ 0.3 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 11 GB (at full 262K context)
VRAM usage by quantization
Q4_K_M21.4 GBQ4_K_M + full context32.1 GB- Can NVIDIA GeForce RTX 4090 run Ornith 1.0 35B?
Yes, at Q4_K_M (21.4 GB) or lower. Higher quantizations like Q5_K_S (24.5 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
- What's the best quantization for Ornith 1.0 35B?
For Ornith 1.0 35B, Q4_K_M (21.4 GB) offers the best balance of quality and VRAM usage. Q5_K_S (24.5 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XXS at 10.0 GB.

- Can I run Ornith 1.0 35B on a Mac?
Ornith 1.0 35B requires at least 10.0 GB at IQ2_XXS, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run Ornith 1.0 35B locally?
Yes — Ornith 1.0 35B can run locally on consumer hardware. At Q4_K_M quantization it needs 21.4 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Ornith 1.0 35B?
At Q4_K_M, Ornith 1.0 35B can reach ~205 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~31 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: NVIDIA B200 → 8000 ÷ 21.4 × 0.65 = ~242 tok/s
Estimated speed at Q4_K_M (21.4 GB)
~242 tok/s~31 tok/s~242 tok/s~205 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Ornith 1.0 35B?
