Model weight size calculator
Estimate theoretical weight-only storage from model parameter count and bit width. Results do not represent runtime VRAM requirements.

Theoretical weight-only floor
17.50 GB
35 × 10⁹ × 4 ÷ 8 bytes
This does not tell you whether a model will run
This estimate only computes parameter count × bit width ÷ 8. Quantisation metadata changes the file size, while runtime also needs a KV cache, compute buffers, framework overhead and system headroom. Architectures such as MoE can further change memory needs depending on where weights are placed.
GB uses decimal bytes (10⁹); GiB uses binary bytes (2³⁰). This is a rough planning aid, not a measurement or a fit guarantee.
