More Agent Bricks and Mosaic AI releases
Every Agent Bricks and Mosaic AI releaseUnity Gateway Skills API and developer tools are available in Beta
The Unity Gateway Skills REST API is now available in Beta , with create, read, update, list, delete, and finalize support across Databricks developer tools: Databricks CLI Python SDK Go SDK Go Modular SDK Java SDK JavaScript SDK See the Skills API and SDK reference .
Agent memory pipelines are in Beta
Agent memory pipelines are in Beta . A memory pipeline connects a session store to a memory store. Each run uses an LLM to distill durable facts, preferences, and decisions from stored conversations into memory entries that your agent recalls in later conversations. You can run a pipeline on demand or about every 24 hours. See Agent memory pipelines .
Knowledge Assistant and Supervisor Agent are now legacy
Knowledge Assistant and Supervisor Agent are now legacy offerings. For new agents written in code, Databricks recommends the Agent Bricks CLI . To build agents without code, use Genie Agents . See Legacy agent offerings .
Use request tags in Unity Gateway service policies (Beta)
Custom service policies in Unity Gateway can now check caller-supplied request tags, such as requiring a tag before a model request or MCP tool call proceeds. See Request tags .
Use OpenJev as the evaluator for LLM-as-a-judge service policies (Beta)
You can now select OpenJev (Qwen3.5 4B) as the evaluator model service of a custom LLM-as-a-judge service policy. OpenJev classifies content without generating output tokens, so it typically responds faster than a chat evaluator. See Use OpenJev as the evaluator .
Unity Gateway supports Amazon Bedrock Mantle
You can now access Amazon Bedrock Mantle models through Unity Gateway model provider services, with Unity Catalog permissions, rate limits, budgets, and inference tables. See Model providers external to Databricks .
Anthropic Claude Haiku 5.5 is now available on Unity Gateway
Anthropic Claude Haiku 5.5 is now available on Unity Gateway. You can access this model using Foundation Model APIs . Customers are responsible for ensuring their compliance with applicable terms .
Enforce partner guardrails with external service policies (Beta)
You can now enforce a third-party guardrail on Unity Gateway traffic. An external service policy sends request and response content to your guardrail vendor and blocks the call when the vendor denies it, with no changes to your applications. See Enforce a partner guardrail with an external service policy .
Also shipped on Oct 13, 2026
Databricks in October 2026What's included:
- Three training methods: Supervised fine-tuning (SFT) , direct preference optimization (DPO) , and reinforcement learning with group relative policy optimization (GRPO) . Each method trains a low-rank adapter (LoRA) or the full model weights. Custom loss functions : Train with any objective you compute in PyTorch from the model's log-probabilities.
The AI.AGG function is generally available (GA)
The AI.AGG function is generally available (GA). You can use this function to semantically aggregate unstructured input data based on natural language instructions.
BigQuery generative AI functions now support the gemini-4-argon model
BigQuery generative AI functions now support the gemini-4-argon model. This model is generally available .
Gemini 4 Argon in CodeMender (Preview)
CodeMender now supports Gemini 4 Argon. To use it, pass --model gemini-4-argon to cm find , cm verify , or cm fix . Gemini 3.8 Flash remains the default model. For more information, see Specifying the model .
Gemini 4 Argon and Gemini 4 Argon Cyber Permissive
Gemini 4 Argon ( gemini-4-argon ) is available in General Availability (GA) . Gemini 4 Argon is Google's frontier model that excels at deep work in complex, real-world tasks across domains including coding, finance, legal, cybersecurity, and science.
