Open-Source AI Index Tuning That Runs Inside SQL Server

If your Power BI models sit on top of SQL Server, whether that is DirectQuery, Import from relational sources, or composite models, the indexes on the source tables have a lot to say about how fast your visuals and refreshes run. aisqltuner-index-tuner is a free, MIT-licensed project that does AI index tuning from inside the database, with one stored procedure. What it does sp_AIIndexTuner collects the index diagnostics for a database, sends them to your own Azure OpenAI deployment, stores the recommendations in a table, and can create the new indexes it is able to verify. EXEC dbo.sp_AIIndexTuner; -- recommend only (the default) EXEC dbo.sp_AIIndexTuner @SchemaName = N'Sales', @TableName = N'Orders'; EXEC dbo.sp_AIIndexTuner @Mode = 'CREATE'; -- also create verified new indexes The model sees missing index suggestions, index usage, duplicate and overlapping indexes, the top plan cache statements, Query Store wo...

AI SQL Tuner Studio 1.0.40 Adds Dark Mode, a New UI, and Export SQL

If your Power BI models sit on top of SQL Server, whether that is DirectQuery, Import from relational sources, composite models, or a dedicated warehouse, the speed of your reports is tied to the speed of the database underneath. AI SQL Tuner Studio 1.0.40 is out, and the headline change is the interface. The product now has a reworked UI, a new Paper and Teal color palette, full Dark Mode, one-click Export SQL, and an upgraded Help menu. What's actually new Version 1.0.40 is a user experience release. The tuning engine and the AI models are unchanged from the previous version.

The six tuning goals (Server Health Check, Fix Deadlocks, Index Tuning, Locking and Blocking Analysis, Code Review, and Query Tuner) are now tappable cards instead of a list. The console moved into a collapsible drawer at the bottom of the window, which gives the HTML report a lot more room. The tuning goal panel collapses as well, and the...

AI SQL Tuner Studio 1.0.28 — Introducing Query Tuner

AI SQL Tuner Studio 1.0.28 is now available, and it introduces a significant new capability: Query Tuner . This release also rolls up Index Tuning improvements that shipped in 1.0.27 but were never formally announced. Query Tuner: AI-Powered Execution Plan Analysis Query Tuner is a new tuning goal that analyzes a single SQL query in depth. Point it at any stored procedure, ad-hoc query, or batch, and it captures the estimated execution plan via SET SHOWPLAN_XML ON , then parses the plan XML to identify referenced tables, operators, warnings, and missing index hints. From there it collects targeted metadata — index usage stats, DMV missing indexes, table sizes, foreign keys, column cardinality, and statistics settings — scoped only to the tables your query actually touches. Everything is sent to the AI model, which returns prioritized, evidence-based recommendations specific to that query. What You Get in the Report The Query Tuner report is structured around actionable secti...
