Announcing Spice.ai Open Source 1.0-stable: A Portable Compute Engine for Data-Grounded AI — Now Ready for Production

🎉 Today marks the 1.0-stable release of Spice.ai Open Source—purpose-built to help enterprises ground AI in data. By unifying federated data query, retrieval, and AI inference into a single engine, Spice mitigates AI hallucinations, accelerates data access for mission-critical workloads, and makes it simple and easy for developers to build fast and accurate data-intensive applications across cloud, edge, or on-prem.

Enterprise AI systems are only as good as the context they’re provided. When data is inaccessible, incomplete, or outdated, even the most advanced models can generate outputs that are inaccurate, misleading, or worse, potentially harmful. In one example, a chatbot was tricked into selling a 2024 Chevy Tahoe for $1 due to a lack of contextual safeguards. For enterprises, errors like these are unacceptable—it’s the difference between success and failure.

Retrieval-Augmented Generation (RAG) is part of the answer — but traditional RAG is only as good as the data it has access to. If data is locked away in disparate, often legacy data systems, or cannot be stitched together for accurate retrieval, you get, as Benioff puts it, "Clippy 2.0".

And often, after initial Python-scripted pilots, you’re left with a new set of problems: How do you deploy AI that meets enterprise requirements for performance, security, and compliance while being cost efficient? Directly querying large datasets for retrieval is slow and expensive. Building and maintaining complex ETL pipelines requires expensive data teams that most organizations don’t have. And because enterprise data is highly sensitive, you need secure access and auditable observability—something many RAG setups don’t even consider.

Developers need a platform at the intersection of data and AI—one specifically designed to ground AI in data. A solution that unifies data query, search, retrieval, and model inference—ensuring performance, security, and accuracy so you can build AI that you and your customers can trust.

Spice.ai OSS: A portable data, AI, and retrieval engine

In March of 2024, we introduced Spice.ai Open Source, a SQL query engine to materialize and accelerate data from any database, data warehouse, or data lake so that data can be accessed wherever it lives across the enterprise — consistently fast. But that was only the start.

Building on this foundation, Spice.ai OSS unifies data, retrieval, and AI, to provide current, relevant context to mitigate AI “hallucinations” and significantly reduce incorrect outputs-just one of the many mission-critical use cases Spice.ai addresses.

Spice is a portable, single-node, compute engine built in Rust. It embeds the fastest single-node SQL query engine, DataFusion, to serve secure, virtualized data views to data-intensive apps, AI, and agents. Sub-second data query is accelerated locally using Apache Arrow, DuckDB, or SQLite.

Now at version 1.0-stable, Spice is ready for production. It’s already deployed in enterprise use at Twilio, Barracuda Networks, and NRC Health, and can be deployed anywhere—cloud-hosted, BYOC, edge, on-prem.

Data-grounded AI

Data-grounded AI anchors models in accurate, current, and domain-specific data, rather than relying solely on pre-trained knowledge. By unifying enterprise data—across databases, data lakes, and APIs—and applying advanced ingestion and retrieval techniques, these systems dynamically incorporate real-world context at inference time without leaking sensitive information. This approach helps developers minimize hallucinations, reduce operational risk, and build trust in AI by delivering reliable, relevant outputs.

How does Spice.ai OSS solve data-grounding?

With Spice, models always have access to materializations of low-latency, real-time data for near-instant retrieval, minimizing data movement while enabling AI feedback so apps and agents can learn and adapt over time. For example, you can join customer records from PostgreSQL with sales data in Snowflake and logs stored in S3—all with a single SQL query or LLM function call.

Spice includes an advanced suite of LLM tools including vector and hybrid search, text-to-SQL, SQL query and retrieval, data sampling, and context formatting—all purpose-built for accurate outputs.

The latest research is continually incorporated so that teams can focus on business objectives rather than trying to keep up with the incredibly fast-moving and often overwhelming space of AI.

Spice.ai OSS: The engine that makes AI work

Spice.ai OSS is a lightweight, portable runtime (single ~140 MB binary) with the capabilities of a high-speed cloud data warehouse built into a self-hostable AI inference engine, all in a single, run-anywhere package.

It's designed to be distributed and integrated at the application level, rather than being a bulky, centralized system to manage, and is often deployed as a sidecar. Whether running one Spice instance per service or one for each customer, Spice is flexible enough to fit your application architecture.

Apps and agents integrate with Spice.ai OSS via three industry-standard APIs, so that it can be adopted incrementally with minimal changes to applications.

1. SQL Query APIs: HTTP, Arrow Flight, Arrow Flight SQL, ODBC, JDBC, and ADBC.

2. OpenAI-Compatible APIs: HTTP APIs compatible with the OpenAI SDK, AI SDK with local model serving (CUDA/Metal accelerated), and gateway to hosted models.

3. Iceberg Catalog REST APIs: A unified Iceberg Catalog REST API.

Key features of Spice.ai OSS include:

• Federated SQL Query Across Data Sources: Perform SQL queries across disparate data sources with over 25 open-source data connectors, including catalogs (Unity Catalog, Iceberg Catalog, etc), databases (PostgreSQL, MySQL, etc.), data warehouses (Snowflake, Databricks, etc.), and data lakes (e.g., S3, ABFS, MinIO, etc.).

• Data Materialization and Acceleration: Locally materialize and accelerate data using Arrow, DuckDB, SQLite, and PostgreSQL, enabling low-latency and high-speed transactional and analytical queries. Data can be ingested via Change-Data-Capture (CDC) using Debezium, Catalog integrations, on an interval, or by trigger.

• AI Inference, Gateway, and LLM toolset: Load and serve models like Llama3 locally, or use Spice as a gateway to hosted AI platforms including OpenAI, Anthropic, xAI, and NVidia NIM. Automatically use a purpose-built LLM toolset for data-grounded AI.

• Enterprise Search and Retrieval: Advanced search capabilities for LLM applications, including vector-based similarity search and hybrid search across structured and unstructured data. Real-time retrieval grounds AI applications in dynamic, contextually relevant information, enabling state-of-the-art RAG.

• LLM Memory: Enable long-term memory for LLMs by efficiently storing, retrieving, and updating context across interactions. Support real-time contextual continuity and grounding for applications that require persistent and evolving understanding.

• LLM Evaluations: Test and boost model reliability and accuracy with integrated LLM-powered evaluation tools to assess and refine AI outputs against business objectives and user expectations.

• Monitoring and Observability: Ensure operational excellence with telemetry, distributed tracing, query/task history, and metrics, that provide end-to-end visibility into data flows and model performance in production.

• Deploy Anywhere; Edge-to-Cloud Flexibility: Deploy Spice as a standalone instance, Kubernetes sidecar, microservice, or scalable cluster, with the flexibility to run distributed across edge, on-premises, or any cloud environment. Spice AI offers managed, cloud-hosted deployments of Spice.ai OSS through the Spice Cloud Platform (SCP).

Twilio uses Spice.ai OSS as a data acceleration framework or Database CDN, staging data in object-storage that's accelerated with Spice for sub-second query to improve the reliability of critical services in its messaging pipelines. Before Spice, a database outage could result in a service outage.

"Spice opened the door to take these critical control-plane datasets and move them next to our services in the runtime path."

Peter Janovsky

Software Architect at Twilio

With Spice, Twilio has achieved:

• Significantly Improved Query Performance: Used Spice to co-locate control-plane data in the messaging runtime, accelerated with DuckDB, to send messages with a P99 query time of < 5ms.

• Low-Latency Multi-Tenancy Controls: Spice is integrated into the message-sending runtime to manage multi-tenancy data controls. Before, data changes required manual triggers and took hours to propagate. Now, they update automatically and reach the messaging front door within five minutes via a resilient data-availability framework.

• Mission-Critical Reliability: Reduced reliance on queries to databases by using Spice to accelerate data in-memory locally, with automatic failover to query data directly from S3, ensuring uninterrupted service even during database downtime.

"With a simple drop in container, we are able to double our data redundancy by using Spice."
