Memory is the weights at that precision plus 20% for the runtime and a short context; a long context needs more. Prices are the lowest on-demand hourly rates in the SAVRN Index, read Sep 18, 2026.

SAVRN's Notes on Octen-Embedding-8B

Eighteen point two gigabytes: that is what Octen-Embedding-8B needs in 16-bit, against 15.1 GB of weights, and it is the figure that decides where this model lives. The lowest-priced host is one MI300X at $1.85 per hour on-demand, which leaves most of the card for the rest of a retrieval stack. Drop to 8-bit and the need falls to 9.1 GB; 4-bit is 4.5 GB. Octen-Team fine-tuned it from Qwen/Qwen3-Embedding-8B for semantic search and retrieval across multiple languages, and it runs through the sentence-transformers library.

Licensing is not the obstacle here: Apache 2.0 permits commercial use, modification and redistribution, with notices kept, significant changes stated and an express patent grant. Check one thing before committing: the configuration lists 40,960 tokens of context while the publisher's summary says up to 32,768, so test at the window you intend to index. Run the base it derives from as the comparison point.
