Frequently Asked Questions
How much VRAM does Param 1 2.9B Instruct need?
Param 1 2.9B Instruct requires 6.3 GB of VRAM at BF16. Full 8K context adds up to 0.8 GB (7.1 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 2.9B × 16 bits ÷ 8 = 5.7 GB
KV Cache + Overhead ≈ 0.6 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 ≈ 1.4 GB (at full 8K context)
VRAM usage by quantization
Can I run Param 1 2.9B Instruct on a Mac?
Yes — Mac Mini M2 Pro (16 GB) and 133 other Macs can run Param 1 2.9B Instruct. Apple Silicon uses unified memory, so the model shares RAM with the system. At BF16 you need at least 6.3 GB of usable unified memory (RAM minus macOS overhead).
Can I run Param 1 2.9B Instruct locally?
Yes — Param 1 2.9B Instruct can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Param 1 2.9B Instruct?
At BF16, Param 1 2.9B Instruct can reach ~763 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~104 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 ÷ 6.29 × 0.65 = ~827 tok/s
Estimated speed at BF16 (6.3 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
