Frequently Asked Questions
How much VRAM does OTel 2.0 LLM 31B IT need?
OTel 2.0 LLM 31B IT requires 20.4 GB of VRAM at Q4_K_M, or 64.2 GB at BF16. Full 262K context adds up to 33.0 GB (53.4 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 31.3B × 4.8 bits ÷ 8 = 18.8 GB
KV Cache + Overhead ≈ 1.6 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 ≈ 34.6 GB (at full 262K context)
VRAM usage by quantization
Can NVIDIA GeForce RTX 4090 run OTel 2.0 LLM 31B IT?
Yes, at Q5_K_M (23.9 GB) or lower. Higher quantizations like Q6_K (27.4 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
What's the best quantization for OTel 2.0 LLM 31B IT?
For OTel 2.0 LLM 31B IT, Q4_K_M (20.4 GB) offers the best balance of quality and VRAM usage. Q5_K_M (23.9 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 14.9 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run OTel 2.0 LLM 31B IT on a Mac?
Yes — Mac Mini M5 Pro (24 GB) and 106 other Macs can run OTel 2.0 LLM 31B IT. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 20.4 GB of usable unified memory (RAM minus macOS overhead).
Can I run OTel 2.0 LLM 31B IT locally?
Yes — OTel 2.0 LLM 31B IT can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is OTel 2.0 LLM 31B IT?
At Q4_K_M, OTel 2.0 LLM 31B IT can reach ~235 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~32 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 ÷ 20.4 × 0.65 = ~255 tok/s
Estimated speed at Q4_K_M (20.4 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of OTel 2.0 LLM 31B IT?
