Released: April 18, 2026
TL;DR — AI SQL Tuner Studio 1.0.29.0 adds two new AI models from Anthropic: Claude Sonnet 4.6 and Claude Opus 4.6. Both run alongside the existing GPT-5.4 option. Sonnet 4.6 is available in every edition. Opus 4.6 is exclusive to the Corporate edition. The Free edition runs at low reasoning effort; Standard, Pro, and Corporate unlock medium and high reasoning effort as well.
What’s new in 1.0.29.0
Version 1.0.29.0 expands the AI model menu inside AI SQL Tuner Studio. Until now, recommendations were powered by GPT-5.4. Starting with this release, you can also choose one of Anthropic’s Claude models for every tuning task — Server Health Check, Query Tuner, Index Insights, Deadlock Analysis, and Code Review.
The new models are built in. You don’t need your own Anthropic API key, an Azure resource, or an AWS Bedrock account to use them. Pick the model from the dropdown, run the analysis, and read the report.
The new model lineup
| Model | Provider | Available in |
|---|---|---|
| Claude Sonnet 4.6 | Anthropic | Free, Standard, Pro, Corporate |
| Claude Opus 4.6 | Anthropic | Corporate only |
| GPT-5.4 | OpenAI | Free, Standard, Pro, Corporate |
Sonnet 4.6 is Anthropic’s balanced model — fast, cost-effective, and well-suited to the majority of tuning jobs. Opus 4.6 is Anthropic’s most capable model and is reserved for the Corporate edition, where the deepest analysis is most useful.
How reasoning effort works
Every AI recommendation in the Studio runs at a reasoning effort level. Higher effort means the model thinks longer and returns more detailed findings. Lower effort returns a quicker, shorter report.
| Edition | Low | Medium | High |
|---|---|---|---|
| Free | ✅ | — | — |
| Standard | ✅ | ✅ | ✅ |
| Pro | ✅ | ✅ | ✅ |
| Corporate | ✅ | ✅ | ✅ |
Free users run at low reasoning effort. That’s still enough to produce a complete Server Health Check or query recommendation — just with shorter explanations and a tighter focus on the top issues.
Standard, Pro, and Corporate users can dial reasoning effort up to medium or high when a deeper review is worth the extra thinking time. High effort is a good fit for complex query plans, stubborn deadlocks, and broad health checks across large servers.
Which model should you pick?
Both model families produce useful recommendations. A simple rule of thumb:
- Start with Claude Sonnet 4.6 or GPT-5.4 for day-to-day tuning. They’re quick, and they handle the majority of Server Health Check findings and query rewrites well.
- Reach for Claude Opus 4.6 (Corporate) when you’re chasing a tough problem — a query with a subtle logic issue, a complex execution plan, or a health check on a busy server where you want the most thorough write-up.
- Turn up reasoning effort on any paid edition if a report feels too brief or you want the AI to consider more alternatives.
You can run the same analysis under a different model and compare the two reports side by side. That’s often the fastest way to build confidence in a recommendation before you change production.
See it in action: sample report
We’ve generated a sample Server Health Check report using Claude Opus 4.6 at low reasoning effort, so you can see the format, structure, and level of detail before you install.

How to get the new models
- Update to 1.0.29.0. Open AI SQL Tuner Studio and let the built-in updater run, or download the latest installer from the Downloads page.
- Open or create a connection. Connect to the SQL Server instance you want to review.
- Pick a goal. In the Tuning panel, choose Server Health Check, Query Tuner, or another goal.
- Select the AI model. The AI Model dropdown now shows Claude Sonnet 4.6, Claude Opus 4.6 (Corporate only), and GPT-5.4.
- Choose reasoning effort. Free edition runs at low. Paid editions can select low, medium, or high.
- Run analysis. The HTML report opens in the Preview pane. Save it or open it in your browser for sharing.
Read-only permissions are still all that’s required on the SQL Server side: VIEW SERVER STATE and VIEW DATABASE STATE. The Studio does not write to your server.
Frequently asked questions
Do I need an Anthropic API key to use Claude Sonnet 4.6 or Opus 4.6? No. Anthropic models are built into AI SQL Tuner Studio 1.0.29.0. There are no separate API keys, endpoints, or cloud accounts to configure.

Can I switch between Claude and GPT without reinstalling? Yes. The AI Model dropdown is a per-run setting. You can re-run the same analysis under a different model and compare the results.
Does this change which SQL Server editions are supported by which product edition? No. SQL Server edition coverage is unchanged. Free supports SQL Server Developer Edition; Standard covers SQL Server Standard and Managed Instance General Purpose; Pro covers Enterprise and Managed Instance Business Critical; Corporate covers multi-instance environments for corporations and ISVs.
