Frequently Asked Questions
How much VRAM does Internlm2 5 7B Chat need?
Internlm2 5 7B Chat requires 4.8 GB of VRAM at Q4_K_M, or 14.6 GB at BF16. Full 33K context adds up to 4.0 GB (8.8 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 7B × 4.8 bits ÷ 8 = 4.2 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 ≈ 4.6 GB (at full 33K context)
VRAM usage by quantization
What's the best quantization for Internlm2 5 7B Chat?
For Internlm2 5 7B Chat, Q4_K_M (4.8 GB) offers the best balance of quality and VRAM usage. Q5_K_M (5.6 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 3.5 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Internlm2 5 7B Chat on a Mac?
Yes — Mac Mini M2 Pro (16 GB) and 133 other Macs can run Internlm2 5 7B Chat. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 4.8 GB of usable unified memory (RAM minus macOS overhead).
Can I run Internlm2 5 7B Chat locally?
Yes — Internlm2 5 7B Chat can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Internlm2 5 7B Chat?
At Q4_K_M, Internlm2 5 7B Chat can reach ~1006 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~137 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 ÷ 4.77 × 0.65 = ~1090 tok/s
Estimated speed at Q4_K_M (4.8 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Internlm2 5 7B Chat?
