What runs Phi-4
Dense 14B model from December 2024 and the most downloaded full-size Phi on Hugging Face. Short 16K context; fits 12 GB GPUs at 4-bit.
- Parameters
- 14.7B
- 4-bit file
- 8.3 GB
- Q4_K_M
- Needs at 8k context
- 11.3 GB
- Longest context
- 16,384 tokens
Context memory: 204,800 bytes per token. Standard GQA: 2 x 40 layers x 10 KV heads x 128 head dim x 2 bytes (fp16); head dim = hidden_size 5120 / 40 heads (config has no head_dim). 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.
No published run on a machine that fits it.
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.
