Open-sourcing Metals v2: Databricks’ Java and Scala language server for multi‑million line codebases
Summary
Metals v2 brings full Java support alongside its established Scala language server, letting teams with some of the industry's largest Java codebases pilot it for multi-million line monorepos that outgrow conventional JVM tooling. Now open source, the v2 architecture is built around the priorities AI coding shifts toward: low setup cost, fast feedback, and reliable codebase orientation over broad autocomplete and refactoring features.

What are AI Hallucinations?
What are AI hallucinations, why does it matter, and what can enterprises do about it? Newer reasoning models from OpenAI and DeepSeek are actually hallucinating more than their predecessors, not less, making detection and prevention a must for any production deployment. Enterprises can curb the risk with retrieval-augmented generation, domain-specific fine-tuning, systematic evaluation frameworks, and strong data governance.
Smart Routing in Unity AI Gateway: Match frontier quality with 30%+ lower cost per task
Smart Routing in Databricks Unity AI Gateway automatically directs coding tasks to the optimal model and harness across the price/performance frontier, matching frontier-level quality while cutting cost per task by more than 30%. The feature addresses the growing diversity of models and harnesses practitioners face by handling that selection for them rather than requiring manual tuning.
Databricks Network Configuration delivery to Tens of Millions of Serverless VMs
Databricks rebuilt serverless network configuration delivery around an event-driven pipeline, replacing synchronous upstream calls with background pre-computation served from a snapshot store, which removed expensive multi-service aggregation from the cluster-startup path. At billions of requests per day, the change cut RPC p99 latency by 98.5% (5,000ms to 75ms), lifted availability to 99.99%, and reduced upstream call volume by 86%.
