FAQs

Common Questions

1. What makes ZeroEntropy different from traditional search engines?

Traditional search uses static keyword or semantic matching. ZeroEntropy is optimized for retrieval quality out of the box — combining dense, sparse, and reranked relevance in a single API.

We treat every query as a learning opportunity:

You get state-of-the-art relevance, not a bag-of-words match.
You don’t need to tune BM25 weights, vector thresholds, or rerank configs — we handle that.
You don’t maintain an infra Frankenstein of vector DBs, LLMs, pipelines — we unify it.

2. Does ZeroEntropy handle PDF parsing and chunking?

This is the answer.

3. How does ZeroEntropy process the data I send? Can you deploy on premise?

We take security very seriously. ZeroEntropy is SOC 2 Type 2 and HIPAA compliant.
We also offer a fully managed EU-based instance to comply with regional boundaries.
For additional control, ZeroEntropy can be deployed on-premise.

4. Is there a free trial?

Yes. You can try our Starter plan free for two weeks, including 1,000 queries and 1M tokens of ingestion.

5. What is the query latency?

Here is a table summarizing latencies for both the search engine and reranker:

	Reranker (75 kb payload)	Retrieval API (205MB of UTF8 bytes)	Retrieval API + Reranker
p50	129.7 ms	156.1 ms	220.5 ms
p90	146.1 ms	181.4 ms	253.1 ms
p99	193.9 ms	276.2 ms	320.2 ms
