all-mpnet-base-v2 How much memory it needs, what its licence allows, and whether it fits an office box.
Short answer. all-mpnet-base-v2 needs about 1.6 GB of memory at 4-bit, 1.6 GB at 8-bit and 1.7 GB at full 16-bit precision, including runtime overhead. It has about 109 million parameters and a 514-token context window. Licence in short: commercial use allowed. By memory alone, on ANVE’s launch configurations: ANVE One fits at BF16, ANVE Office fits at BF16, ANVE Office Pro (GPU) fits at BF16. These are estimates from its published size, not benchmarks.
01
What it is
all-mpnet-base-v2 is an embedding model that turns text into vectors for document search, published by the Sentence Transformers project on Hugging Face on 2 March 2022. It has about 109 million parameters and a configured context window of 514 tokens.
Its card lists the licence as Apache 2.0. In short, the licence allows commercial use, modification and redistribution, with attribution and a copy of the licence, and includes a patent grant.
Hugging Face counted about 19,146,408 downloads of it in the 30 days before we checked (7 Oct 2026), and 1,381 people have liked it there.
02
How much memory it needs
The arithmetic: parameters × bits per weight ÷ 8 gives the weights, plus about 1.5 GB for the runtime. These are planning estimates, not measurements.
Inputs are short, so working memory is small next to the weights.

Will it fit on ANVE?
Arithmetic against the launch specification, not a test: about three quarters of ANVE One’s 64 GB of unified memory for the model (as AMD’s Variable Graphics Memory allows), and the 24 GB on the graphics card in ANVE Office and ANVE Office Pro, which keep the rest of the stack in 64 GB and 128 GB of system memory. ANVE’s tested default is Qwen 3.8 27B; this model is not yet validated on ANVE.

What an office would use it for
For an office, embeddings are what make "find the clause about late fees" work across thousands of documents. The model is small, so it runs beside the main language model without crowding it.

Variants with the same size
all-distilroberta-v1: a distilled, smaller-step version (same parameter count, so the memory figures above apply).
paraphrase-mpnet-base-v2: a variant with the same size and memory needs (same parameter count, so the memory figures above apply).

Questions people ask
How much memory does all-mpnet-base-v2 need?
About 1.6 GB at 4-bit, 1.6 GB at 8-bit and 1.7 GB at full 16-bit precision, including about 1.5 GB of runtime overhead. These are estimates from its parameter count.
Can all-mpnet-base-v2 run on a 24 GB graphics card?
Yes, at BF16 by this estimate, with room left for context.
Is all-mpnet-base-v2 free for commercial use?
Its card lists Apache 2.0, which allows commercial use, modification and redistribution, with attribution and a copy of the licence, and includes a patent grant. Read the licence itself before relying on this summary; it is not legal advice.
What is all-mpnet-base-v2’s context window?
Its configuration sets 514 tokens. Longer contexts need more memory for the KV cache, so the practical limit on a given machine can be lower.
