What Enterprise adds to Team

Enterprise includes everything in Team, without the two-server limit and with more than twice the analyses.

	Team	Enterprise
Server connections	Up to 2	Unlimited
Analyses per month	150	400
GPT-5.6 Luna and GPT-6 Sol	✓	✓
Reasoning effort	Low, Medium, High	Low, Medium, High
Bring your own AI endpoint, with no monthly limit	✓	✓
All six tuning goals	✓	✓
Every SQL Server platform	✓	✓

• Every server, one license. Tune production, staging and development across on-premises SQL Server, Azure SQL Database, Managed Instance and Fabric, with no connection limit.
• 400 analyses a month. Enough for regular health checks across your estate, index and code reviews before every release, and the incidents in between.
• Both models, every reasoning level. Run hard problems through GPT-6 Sol and GPT-5.6 Luna and compare the advice before you change anything.

Built for large SQL estates

• Consultants and ISVs. Tune every client or customer server under one license, with reports you can hand over: an executive summary, prioritized findings and ready-to-run T-SQL.
• Platform and DBA teams. Run Server Health Checks across your fleet, then go deep with Index Tuning, Code Review and Fix Deadlocks where the problems are.
• Regulated environments. Bring your own AI endpoint to keep the AI processing in your own Azure tenant, with no monthly limit.

Two models: GPT-6 Sol and GPT-5.6 Luna

Both models are hosted on Microsoft Foundry in Azure, and both earned their place on real benchmark workloads, where we apply each model’s advice and measure what it actually does to the workload.

• Query Tuner: with the execution plan in hand, GPT-6 Sol’s advice cut our benchmark query’s run time by 97 to 100 percent in every run.
• Index Tuning: on our OLTP benchmark with a realistic workload history, GPT-6 Sol’s index advice cut total workload time by a median of 44 percent.
• About a minute per report at Medium reasoning effort, with either model.

Pick the model for each analysis. For GPT-6 Sol, use Medium or High reasoning effort. See the benchmark results.

Six tuning goals, one desktop app

Every goal collects the right diagnostics from your server, sends them to the AI, and returns an HTML report with an executive summary, prioritized findings and T-SQL scripts you can review and run.

Goal	What you get
Query Tuner	Paste a slow query. Studio reads its execution plan and every table it touches, then returns the costliest operators, index scripts with their estimated size, and a rewritten query.
Index Tuning	Database-wide index advice from Query Store and usage statistics: missing, duplicate and unused indexes, each with the storage it adds or frees. Drop advice waits until the server has been up long enough to trust the numbers.
Server Health Check	An executive-level view of your instance: configuration, memory, waits, storage, tempdb, and patch level, with the issues that matter most first.
Code Review	A review of your stored procedures, functions, triggers and views, with full replacement scripts for the code that needs fixing.
Fix Deadlocks	Reads your deadlock history, pulls the code each session was running, and returns rewritten procedures that prevent the deadlock.
Locking and Blocking Analysis	Shows what is blocking what right now, why, and the changes that keep work flowing.

Bring your own AI endpoint

Enterprise can also send analyses to an AI model you run in your own Azure subscription instead of our hosted service.

• No monthly limit. Analyses on your own endpoint don’t count against your 400. Your AI provider bills you for the usage directly.
• Your data path, your rules. Studio sends the diagnostics straight from your machine to your endpoint. They never pass through AI SQL Tuner’s service, which only confirms your license is active.
• Your choice of model. Use GPT models deployed in Azure OpenAI, or Claude models deployed in Microsoft Foundry.
• Your key stays on your machine. Your API key is entered in Studio and saved locally only if you choose to. It is never sent to AI SQL Tuner.

Setup takes about five minutes: Configure your own AI endpoint in 5 steps.

Advice you can check

AI SQL Tuner Studio is built to give advice you can verify, not guesses:

• Grounded in your data. Every figure in a report is quoted from what Studio collected, or clearly labelled as an estimate with what it is based on. When data is missing, the report says so.
• Storage sizes on every index change. Know what a recommendation will cost on disk before you run it.
• Ready-to-run scripts. Reports include complete T-SQL, not vague suggestions.
• Tested on real workloads. We benchmark every model on real Index Tuning, Query Tuner and Code Review workloads and measure what the advice actually does.

How it works

1. Start your free trial. Check out with your email address and a payment card. Nothing is charged today; your $20 monthly subscription starts after 14 days unless you cancel.
2. Install and activate. Download Studio, click License…, and paste the license key from your purchase receipt.
3. Connect and run. Connect each server with a least-privileged SQL login, pick a tuning goal and a model, and click Run Analysis. Your report starts streaming in within seconds.

No agents to install on your servers. No log shipping. No changes to your databases unless you choose to run a script.

---

Your data stays under your control

• You see everything before it’s sent. Before each run, Studio shows a run plan listing every collector and the system views it reads. Nothing is sent until you approve it. Save the plan as JSON to attach to a change-control ticket or a security review.
• Only metadata leaves your machine. Studio sends diagnostic metadata, such as query text, execution plans, index statistics and configuration, to the AI model: our hosted models on Microsoft Foundry in Azure, or your own endpoint. Table data and query results are never sent.
• Nothing is kept by default. Each analysis is answered and discarded. You can opt in to share analyses to help improve the advice, and delete anything shared from inside the app.
• Read-only by design. Studio runs with a least-privileged login and never changes your databases on its own.

Frequently asked questions

How does the 14-day free trial work?

You get the full Enterprise edition, including GPT-6 Sol and unlimited server connections, for 14 days. A payment card is required at checkout, but nothing is charged until the trial ends. After that, Enterprise is billed at $20 a month, plus applicable tax, until you cancel.

What does “unlimited server connections” mean?

Enterprise has no limit on the number of SQL Server instances, Azure SQL servers, Managed Instances or Fabric SQL databases you can connect to. Pro and Team are licensed for up to two.

What counts as an analysis?

Each run of a tuning goal on our hosted AI service counts as one analysis, with either model. A run that times out does not count, and runs on your own AI endpoint never count. The app shows how many analyses you’ve used and when your count resets.

What happens when I use all 400 analyses?

Hosted runs pause until your monthly count resets. You can keep tuning on your own AI endpoint, which has no monthly limit.

Does bringing my own AI endpoint use my monthly quota?

No. Analyses on your own endpoint are unlimited and never count against your 400. Studio calls your endpoint directly, and your AI provider bills you for the usage.

Which AI models are included?

On our hosted service, GPT-5.6 Luna and GPT-6 Sol, both chosen from our benchmark results and hosted on Microsoft Foundry in Azure. With your own endpoint, you can use GPT models deployed in Azure OpenAI or Claude models deployed in Microsoft Foundry.

I bought AI SQL Tuner Studio Corporate. What changed?

Corporate is now called Enterprise, at the same price. Your existing license key keeps working and activates as Enterprise. The hosted Claude Opus models were retired after GPT-6 Sol outperformed them on every workload we tested; GPT-6 Sol is included in Enterprise, and you can still use Claude models through your own AI endpoint.

Can I change editions later?

Yes. You can switch to Team or Pro at any time if you no longer need unlimited connections.

Is my data stored in the cloud?

No, not by default. Each analysis is answered and discarded. Studio sends diagnostic metadata to the AI for analysis, never table data or query results, and you see the full run plan before anything is sent. With your own endpoint, the diagnostics go only to your endpoint.
