What runs Gemma 4 26B-A4B IT
Gemma 4 MoE with 25.2B total and 3.8B active parameters. The most downloaded Gemma 4 size, quick on 16-24 GB GPUs and 32 GB Macs.
- Parameters
- 25.2B, 3.8B active
- 4-bit file
- 15.9 GB
- Q4_K_M
- Needs at 8k context
- 17.4 GB
- context memory estimated
- Longest context
- 262,144 tokens
Context memory: 10,240 bytes per token, an estimate from the config: 5 global layers x 2 KV heads x 512 x 2 bytes, K only; 25 sliding-window layers are fixed-size. 25 of 30 layers use 1,024-token sliding-window attention; 5 global layers use 2 KV heads of dim 512 with keys shared as values. Only the global layers grow with context. Card gives no per-token figure. How context memory works.
Measured on this hardware
Machines that hold the 4-bit file with 8,192 tokens of context and have published runs on the same chip or cards, fastest first. Median of single-user runs with plain decoding.

Estimated, not measured
These fit but nobody has published a run we could match. The figure is memory bandwidth divided by the bytes read per token, scaled by the share of that ceiling measured runs reach. How estimates work.
