description: "Claude Fable 5 is now generally available on Databricks, with rollout across AWS, Azure, and Google Cloud through Unity AI Gateway. The Mythos-class model targets long-running, complex, and ambiguous work, including autonomous enterprise workflows, document question answering, code investigation, and multimodal tasks. In Databricks' OfficeQA Pro benchmark, Fable 5 achieved 57.9% correctness, setting a state of the art; compared with Claude Opus 4.8, it was 20% more accurate and used 12% fewer tool calls, but ran approximately 30% slower and generated 2.5x more output tokens. Unity AI Gateway provides unified API access, fine-grained permissions, Unity Catalog logging, request and tool-call guardrails, and spend controls. Agent Bricks supports domain-specific agents, while Anthropic's policy includes 30-day retention for trust and safety purposes only."

## Summary

Claude Fable 5 is now generally available on Databricks, with rollout across AWS, Azure, and Google Cloud through Unity AI Gateway. The Mythos-class model targets long-running, complex, and ambiguous work, including autonomous enterprise workflows, document question answering, code investigation, and multimodal tasks. In Databricks' OfficeQA Pro benchmark, Fable 5 achieved 57.9% correctness, setting a state of the art; compared with Claude Opus 4.8, it was 20% more accurate and used 12% fewer tool calls, but ran approximately 30% slower and generated 2.5x more output tokens. Unity AI Gateway provides unified API access, fine-grained permissions, Unity Catalog logging, request and tool-call guardrails, and spend controls. Agent Bricks supports domain-specific agents, while Anthropic's policy includes 30-day retention for trust and safety purposes only.

## Context

Databricks customers need to run highly autonomous, long-running AI workflows against enterprise data while retaining governance, access control, auditability, safety protections, and visibility into increased model spending.

## Approach / What changed

Claude Fable 5 is offered through Unity AI Gateway across Databricks cloud environments, with unified API access, permissions, logging, LLM and tool-call guardrails, spend controls, and cost analytics. Agent Bricks enables domain-specific agents that can deploy as managed Databricks Apps with authentication, access controls, and Lakebase-powered memory.

## Takeaways

- On the OfficeQA Pro benchmark, Claude Fable 5 reached 57.9% correctness, with 20% higher accuracy and 12% fewer tool calls than Claude Opus 4.8, while running about 30% slower and producing 2.5x more output tokens.
- Unity AI Gateway logs requests, responses, and tool-call actions to Unity Catalog or Delta tables, while policies can block operations, restrict them to admins, or require consent for writes.
- AI Spend Controls support thresholds by user, use case, workspace, and account, and Cost Analytics breaks spending down by model, provider, workspace, and user.
