Peak VRAM for serving this model, computed by lib/deployment/hardware.ts from weights + KV cache + 15% runtime overhead. Inputs: 27.4B parameters, 8,192 tokens of context (assumed — none fetched yet), 4 concurrent requests (assumed).

  The step up when answer quality matters more than price: a 32B model at 4-bit with generous KV cache, or a 14B model at fp16 with a long context. ECC memory and a standard 2U chassis mean it belongs in a rack or comms room rather than under a desk.

  Sizing basis

  • Weights: 27.4B parameters × 2 bytes per parameter (fp16) = 54.86 GB.
  • No model configuration was supplied, so the KV cache uses the size heuristic for this band: 0.262 MB per token, from Qwen2.5-32B-Instruct (64 × 8 × 128).
  • KV cache: 0.262 MB per token × 8,192 tokens of context × 4 concurrent requests = 8.59 GB, sized for every user holding a full context at once.
  • Overhead: 15% of weights plus KV cache for the runtime, activations and memory fragmentation = 9.52 GB.
  • GB means 10⁹ bytes, matching how GPU memory is advertised.
  • KV cache held at fp16 (2 bytes per element); quantising weights does not by itself quantise the cache.
  • Peak figure, not average: prefix caching and paged attention usually keep real usage lower, while speculative decoding, CUDA graphs and a second resident model push it higher.
  • "Concurrent" counts requests generated at the same instant, not people: 4 simultaneous requests is the worst case this estimate is built on — measure yours before buying.

  Quiet, standard-socket power draw, and a large memory pool — about 75% of installed unified memory is addressable by the GPU, which is where the 96 GB figure comes from on a 128 GB M4 Max. Memory bandwidth, not capacity, sets the ceiling: excellent for a pilot, a partner workstation or a single heavy user, weak for 40 people at once. Runs Ollama, llama.cpp and MLX; does not run CUDA builds of vLLM.

  For a 70B-class model at fp16/int8 with tensor parallelism, or several mid-size models served side by side. Needs real data-centre conditions: 4–8 kW of power, front-to-back cooling and a rack. The price band is wide because A100 and H100 are several times apart.
