Notre méthode

Nous partons des tailles et quantifications documentées, réservons de la mémoire au système et traitons le cache comme un coût en plus. MoE utilise le total.

Nous séparons paramètres totaux, paramètres MoE actifs, poids quantifiés, support et performances mesurées.

  • Memory fit is an estimate, not a speed measurement.
  • Size MoE by total parameters; shared and distributed memory need additional checks.
  • Vendor claims, community measurements, runtime conditions and unknowns are disclosed separately.

Does a 24 GB GPU run a 30B model?

Often at Q4/INT4 with a conservative context. Qwen3 30B-A3B and Gemma 3 27B are representative fits, but cache and runtime overhead still matter.

Are active MoE parameters the memory requirement?

No. Active parameters affect compute per token; total parameters still need to be stored in memory or offloaded.

Which runtime should a beginner choose?

Ollama for a terminal-first setup or LM Studio for a visual desktop. llama.cpp is the portable fallback; vLLM is for higher-throughput GPU serving.

How do you report speed?

Exact device-and-model measurements are labeled measured. Relative manufacturer figures are labeled vendor claims. Every other combination stays unknown instead of receiving an invented tokens-per-second estimate.
