Actian Zen v17 AI: Your Database Just Became AI-Ready

Actian Zen v17 AI brings AI and vector search to the embedded database organizations already trust.

I’m excited to announce the general availability of Actian Zen v17 AI. This is one of the biggest capability releases in Zen’s history, and the first to bring native AI directly into the embedded database engine our customers have trusted for decades.

If you’ve built on Zen, you already know what makes Zen special: a zero-admin, embedded database that runs everywhere from a Raspberry Pi to an enterprise server, without a DBA in sight. With Zen v17 AI, we’re extending that same promise to AI and vector workloads.

Why We Built This and Why it’s Important

Over the past year, nearly every conversation we’ve had with ISVs and OEMs building on Zen has circled back to the same question: How do we add AI-powered search and retrieval to our application without bolting on a separate vector database?

It’s a fair question, and until now, a hard one to answer. Standalone vector databases mean new infrastructure to deploy and a new sync pipeline to keep your relational and vector data consistent. For customers running on-prem or in air-gapped environments, this is a non-starter because most vector databases assume constant cloud connectivity.

Zen v17 AI solves this by putting AI capability inside the engine you’re already running, not next to it. That means less infrastructure to manage, less complexity to maintain, and a faster path to AI.

New Capabilities for the AI Era

Native vector search, right in SQL. Zen v17 AI introduces a native VECTOR data type that stores embeddings alongside your relational data. Cosine, Euclidean, and dot-product similarity queries run directly in standard SQL. Store up to a million vectors out of the box, with approximate nearest-neighbor (ANN) indexing for fast retrieval as your dataset grows. No separate vector store, no export/import step, no new query language to learn.

AI-powered hybrid search. This is where native AI becomes especially powerful: Zen v17 AI lets you combine relational filters, metadata, SQL joins, and vector similarity search in a single query. Ask for “invoices similar to this dispute, from Q3 only,” and get one result set back, not two systems you have to stitch together in application code. One engine, one query, one latency budget.

A built-in MCP server. Zen v17 AI ships with a native Model Context Protocol (MCP) server, so AI agents and LLM tooling such as Claude, ChatGPT, Gemini, or any MCP-compatible agent can query your application’s data the day Zen v17 AI is installed. OAuth 2.1 and HTTP/SSE are supported out of the box, so there’s no custom API layer to build and no integration sprint per AI provider.

Still the Zen you know. The capabilities that made Zen what it is are still here: zero-admin operation, ANSI SQL and Btrieve/Btrieve 2 access, full ACID writes, AES 256-bit encryption, and backward compatibility with every prior PSQL release. No data migration, no rewrites, no excuses to skip the upgrade.

Built for Where Your Data Actually Lives

A theme we hear constantly from Zen customers in manufacturing, healthcare, and financial services is that their AI strategy can’t depend on a cloud connection. Factory floors, hospitals, trading desks, and defense installations frequently can’t route traffic through the cloud, and that shouldn’t mean they’re locked out of AI.

Because Zen v17 AI runs the complete stack–vector storage, ANN indexing, hybrid SQL search, and the MCP server–entirely offline, it’s built for those exact environments:

• Manufacturing: semantic search across equipment manuals, anomaly pattern matching on sensor data, and AI agents generating work orders from real-time maintenance logs, all running at the factory edge.
• Healthcare: RAG-powered clinical knowledge bases and similar-case retrieval that keep patient data inside the facility’s perimeter, supporting HIPAA-compliant deployments.
• Financial services: transaction similarity matching for fraud detection and semantic search over regulatory filings, without data ever crossing the security boundary.

For teams that already have vector application logic built, Zen v17 AI exposes a native vector API alongside SQL access. You can add structured relational queries without rewriting what you’ve already shipped, or let your SQL developers query vectors without learning a new interface. Same engine, your choice of access pattern.

Get Started Today

Zen v17 AI is available now for Enterprise Server and Cloud Server deployments. If you’re already running Zen, upgrading is the same low-friction process it’s always been. If you’re evaluating Zen for the first time, there’s never been a better moment: you can ship AI-powered search and RAG-ready applications without standing up a single new piece of infrastructure.
