Thoughts on data engineering, state of AI, Microsoft Fabric & Power BI.
Power BI Translytical Task Flows solve writeback for simple cases, but complex workflows outgrow them fast. Fabric Data Apps, built on Rayfin, take a different approach: a proper web app hosted in Fabric instead of a feature bolted onto a report. Includes a working FP&A variance commentary example built in about 10 minutes with a coding agent.
v3.9.119 adds HTML model reports, fully configurable DAX formatting, deeper storage diagnostics, flaky-test classification, combined Power Query commits, and new DAX debugging and performance-tuning skills.
v1.1.39 adds browser and device-code sign-in, test stability classification, order-tolerant baselines, virtualized selectors, steadier run behavior, and model-scoped tests that survive migrations.
Microsoft put Dataflow Gen1 into legacy status in April 2026. The UI migrates one dataflow at a time. Here is how I migrate them in bulk with az rest, including the API and deployment-pipeline problems I hit.
A LoRA fine-tune of GPT-OSS-20B improved DAXBench score from 15/30 to 20/30, with 20% more correct results on an independent evaluation set and dramatically reduced response length and latency.
Truly agentic development requires one thing: feedback loops. Many of them. Here is how I think about building them into AI-assisted Power BI work - and why they matter more than the model itself.
Rayfin gives Power BI developers the customizability they've wanted for years, full web apps instead of constrained reports. But that freedom comes with a UX cost and an engineering cost most teams aren't pricing in yet.
SemanticOps Test Runner is a desktop app for creating and running repeatable tests against Power BI semantic models. Catch broken measures, RLS issues, performance regressions, and model-quality problems before changes reach users or production workspaces.
There's no native move option in the Fabric portal. Here's how to do it with a .bacpac export and import using the SqlPackage CLI.
AI can speed up Power BI development, but DAX is still a sharp edge. Benchmarking 70 models shows the biggest failure pattern is not weak business logic, but DAX grammar.
Most Power Query pagination examples break the moment you publish to Power BI Service. Here's a complete, production-ready pattern for cursor-based REST API pagination using Web.Contents with RelativePath, proper auth handling, and a List.Generate implementation that doesn't skip the last page.
Vibe coding removes the friction that used to force natural pauses. The result is a new kind of addiction - and a cognitive overload nobody's talking about.
SemanticOps MCP, formerly MCP Engine, is a local MCP server that connects AI assistants to your Power BI semantic models. Free tier covers core modeling. Pro adds rollback, test runners, policy engines, data masking, and impact analysis — the guardrails you need before letting AI touch production.
A systematic benchmark of large language models on Power BI formula generation reveals which AI assistants are worth using—and why most of them fail on the same patterns.
