Frequently Asked Questions
- How much VRAM does Opus Therapy 9B need?
Opus Therapy 9B requires 5.9 GB of VRAM at Q4_K_M, or 19.8 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 9B × 4.8 bits ÷ 8 = 5.4 GB
KV Cache + Overhead ≈ 0.5 GB (at 2K context + ~0.3 GB framework)
VRAM usage by quantization
Q4_K_M5.9 GB- What's the best quantization for Opus Therapy 9B?
For Opus Therapy 9B, Q4_K_M (5.9 GB) offers the best balance of quality and VRAM usage. Q5_K_M (7.0 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 4.2 GB.

- Can I run Opus Therapy 9B on a Mac?
Opus Therapy 9B requires at least 4.2 GB at Q2_K, 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 Opus Therapy 9B locally?
Yes — Opus Therapy 9B can run locally on consumer hardware. At Q4_K_M quantization it needs 5.9 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Opus Therapy 9B?
At Q4_K_M, Opus Therapy 9B can reach ~491 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~110 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: AMD Instinct MI300X → 5300 ÷ 5.9 × 0.55 = ~491 tok/s
Estimated speed at Q4_K_M (5.9 GB)
~491 tok/s~110 tok/s~367 tok/s~303 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Opus Therapy 9B?
At Q4_K_M, the download is about 5.40 GB. The full-precision BF16 version is 18.00 GB. The smallest option (Q2_K) is 3.83 GB.
- Which GPUs can run Opus Therapy 9B?
