Spice.ai is an open-source, portable data lakehouse and AI runtime that lets teams federate, accelerate, and query data across databases, warehouses, and object storage — then run search and LLM inference on the same engine that scales from a laptop to a multi-node cluster.

Code Arena is a hands-on playground and leaderboard where you can pit leading AI coding models against each other on real web builds, comparing speed, accuracy, and logic in live side-by-side battles.
Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
Watch models construct web apps and websites live, so you can see process and output, not just the final file.
Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
Track which coding models accumulate the most wins over time to identify consistently strong performers.

Spice.ai is an open-source, portable data lakehouse and AI runtime that lets teams federate, accelerate, and query data across databases, warehouses, and object storage — then run search and LLM inference on the same engine that scales from a laptop to a multi-node cluster.
Connect to operational databases, data lakes, and warehouses, and query them through one SQL endpoint. Materialize working sets in-memory or on disk for millisecond access with engines like Cayenne.
Replicate changes from production databases to an isolated analytics replica via high-throughput CDC, so large queries run against near real-time operational data without touching production.
Combine structured filters, vector similarity, and full-text search in a single SQL statement and rank merged results by relevance.
Call hosted or local LLMs inline using SQL UDFs or natural language to translate, summarize, and classify data without leaving the runtime.
