StableLM 2 12B Chat

by Stability AI

The weights fit entirely in accelerator memory on 16 of 22 reference machines. The KV cache or runtime state is not fully modelled, so this is a memory floor, not a "runs" verdict.

Sizes come from the runtime registry or repository listing. The memory floor adds the KV cache for 4,096 tokens when that figure cannot over-count; it is an estimate, not a requirement.

Definitive answers ("runs", "does not fit") come from the calibrated engine or a physical run. "Potential" rows only compare the weights with memory: the rest of the requirement is not modelled, so they are not verdicts. Unknown is never a failure.

Hardware for this model

At least 8 GB of VRAM is needed just to hold the smallest weights (6.49 GB). The complete requirement is higher and not modelled yet.

  • Smallest catalogued artifact: 6.49 GB of weights (Q4_0).
  • A GPU with at least 8 GB of VRAM holds those weights.
  • Not modelled yet: unknown.
