Memory envelope

What changes the fit.

Weights establish the floor. Context, concurrent sequences, cache precision, and runtime overhead determine whether the deployment remains stable.

Efficient

45.7 GiB

Useful starting point for local evaluation and cost-sensitive inference.

Quality-first

155.9 GiB

Preserves original weight precision and establishes a conservative serving baseline.
