Question 1

How many dimensions do the embeddings have?

Accepted Answer

Up to 4096. The model supports user-defined output dimensions from 32 to 4096 (MRL support per the model card), so you can truncate vectors to fit your vector database and latency budget with modest quality loss.

Question 2

What is the maximum input length?

Accepted Answer

The Hugging Face config sets max_position_embeddings to 40,960 tokens, and the model card lists a 32K sequence length. For retrieval quality, chunking long documents into passages is still standard practice.

Question 3

Do I need to add an instruction to my inputs?

Accepted Answer

For queries, yes, ideally: format them as 'Instruct: Query: '. The model card reports a 1-5% retrieval improvement from query-side instructions. Documents should be embedded as-is without an instruction.

Question 4

Can I call it with the OpenAI SDK?

Accepted Answer

Yes. Point the SDK at base_url https://chutes-qwen-qwen3-embedding-8b-tee.chutes.ai/v1 with your Chutes API key and call client.embeddings.create(model="Qwen/Qwen3-Embedding-8B-TEE", input="..."). The endpoint follows the OpenAI embeddings contract.

Question 5

What does the TEE suffix mean?

Accepted Answer

The model runs inside a Trusted Execution Environment: confidential-compute hardware that keeps prompts and outputs encrypted in memory and attestable. It is a serving-level property and does not change the embeddings the model produces.

Question 6

What license is Qwen3-Embedding-8B under? Can I use it commercially?

Accepted Answer

Apache-2.0, per the Hugging Face repo Qwen/Qwen3-Embedding-8B. Apache-2.0 permits commercial use, modification, and redistribution with attribution and license notice.

Question 7

How good is it compared to other embedding models?

Accepted Answer

Its model card reports 70.58 mean task score on MTEB multilingual (No.1 on the leaderboard as of June 5, 2025), 75.22 on MTEB English v2, and 73.84 on C-MTEB Chinese, ahead of gte-Qwen2-7B-instruct, NV-Embed-v2, and text-embedding-3-large in the card's comparison tables.
