Frequently Asked Questions
- How much VRAM does Manaca 1B Instruct need?
Manaca 1B Instruct requires 1.4 GB of VRAM at Q4_K_M, or 3.9 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 1.7B × 4.8 bits ÷ 8 = 1 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 0.5 GB (at full 4K context)
VRAM usage by quantization
Q4_K_M1.4 GBQ4_K_M + full context1.5 GB- What's the best quantization for Manaca 1B Instruct?
For Manaca 1B Instruct, Q4_K_M (1.4 GB) offers the best balance of quality and VRAM usage. Q5_K_M (1.6 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 1.1 GB.

- Can I run Manaca 1B Instruct on a Mac?
Manaca 1B Instruct requires at least 1.1 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 Manaca 1B Instruct locally?
Yes — Manaca 1B Instruct can run locally on consumer hardware. At Q4_K_M quantization it needs 1.4 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Manaca 1B Instruct?
At Q4_K_M, Manaca 1B Instruct can reach ~3357 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~458 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 ÷ 1.4 × 0.65 = ~3636 tok/s
Estimated speed at Q4_K_M (1.4 GB)
~3636 tok/s~458 tok/s~3636 tok/s~3357 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Manaca 1B Instruct?
At Q4_K_M, the download is about 1.03 GB. The full-precision BF16 version is 3.44 GB. The smallest option (Q2_K) is 0.73 GB.
