New Features
Save Credentials Once, Reuse Everywhere: You can now save secrets such as API keys or database passwords once in User Settings and reuse them by name across all sessions. No more re-entering credentials every time you start a new session.
Install on Windows via Winget: Plotly Studio can now be installed on Windows using the Windows Package Manager: winget install Plotly.Studio. Future releases will be published to the winget repository automatically.
Note: We are awaiting approval for our package to be included in the WinGet repository. Approval is expected in the next 1 to 2 weeks.
Improvements
Faster AI Responses: AI processing now runs on a more efficient backend, resulting in faster and more reliable responses throughout the app.
Faster Chart Review and Notes: Chart review and notes generation after running code now complete faster thanks to backend performance improvements.
Fixes
Session Previews Restore Correctly After Restart: Restarting a session preview could previously leave required files missing, causing the preview to fail. Previews now restart reliably every time.
Saved Code Now Persists in Artifact History: Fixed a bug that prevented code changes from being saved in an artifact's version history, so saved versions now correctly reflect your code.
Faster Dash MCP Connections in Deployed Dash Apps: Deployed Dash apps were experiencing slow MCP client connections due to an overly permissive setting. This has been corrected, so deployed apps connect significantly faster and produce quieter logs.

Every app now has a compute mode and an app size that you can change any time from the Compute tab.
Compute modes
Automatically Sleep (default): the app sleeps after 15 minutes of inactivity and wakes automatically on the next request. You only spend credits while it's awake, so it's ideal for internal or occasionally used apps. The trade-off is a 10–30 second cold start on the first request after sleeping.
Always Awake: the app stays running and responds instantly every time. Perfect for widely shared apps, embedded dashboards, or apps running scheduled background jobs.
App sizes
Pick the CPU and memory that fit your workload, from Starter (0.5 vCPU · 1 GB) up to Performance L (8 vCPU · 16 GB). Start small and scale up as traffic and data grow. The Starter size is free in Automatically Sleep mode.
Metered, credit-based billing
Compute draws from your team's shared credit balance and is metered per 5-minute window — you're only charged while the app is actually awake. A new Estimate your credit usage slider on the Compute tab lets you preview monthly cost for any mode and size before you save.
👉 Learn more in the Compute Mode and App Size documentation, or get started by visiting the Compute tab for any of your apps on Plotly Cloud.

Plotly Studio
Improvements
Upgrade to Dash 4.3.0: Plotly Studio now runs on Dash 4.3.0, bringing the latest fixes and improvements from the Dash framework. Your existing projects and sessions will update automatically the next time you restart the app.
Fixes
MacOS Keychain Popup Fix: Fixed an issue on macOS where Plotly Studio would trigger unexpected Keychain permission popups when accessing saved credentials.

Plotly Studio
New Features
Manual Override for Credential Redaction
A confirmation dialog now appears before any secrets redaction is applied. This allows you to avoid accidental redaction for strings that the LLM misidentified as a secret.
Personalized AI-Generated Notes
Notes and methodology generation now takes your personal preferences into account, including language settings. AI-generated content will feel more consistent with how you work.
Fixes
Duplicate Messages No Longer Appear
Messages containing line breaks were occasionally displayed twice in a session. They now appear correctly every time.
All Credentials Are Saved When Set Together
When the AI suggested setting multiple credentials at once, only the first value was being saved. All credentials are now submitted together in a single step.
Charts and Tables Handle Large Content Better
Wide tables with many columns and large stat cards were overflowing their containers. Content now truncates cleanly without breaking the layout.
Long Sessions Are Managed Correctly
In very long conversations, an error related to session length limits was not being caught properly, which prevented automatic session management from working. This has been fixed.
Windows App No Longer Blocked by Antivirus
Some antivirus programs on Windows were quarantining a file created at startup, preventing Plotly Studio from launching. The startup process has been updated to avoid triggering this behavior.

Plotly Studio
New Features
Methodology Section for Analysis Steps: AI-generated analysis steps now include a Methodology section that explains the reasoning behind each step. You can review how Studio arrived at a particular result and verify the approach before acting on it.
Universal Deployment Support: You can now deploy any type of content created in Studio (not just apps) to Plotly Cloud or Dash Enterprise. Previously, only Dash apps could be published.
Fixes
Dependency Update: Updated an underlying library dependency to a newer stable version, resolving minor bugs that could surface in edge cases.

Plotly Studio
New Features
Your preferences now follow you across sessions. You can add personal context to your Studio settings. You can add things like preferred color schemes, data conventions, or output formatting rules, and the AI will apply them automatically in every session without you having to repeat yourself each time.
Improvements
Longer AI responses now complete reliably. When Studio's AI hits a length limit mid-response, it automatically picks up where it left off, so complex code generation and multi-step analyses are no longer cut short without explanation. If a response still can't complete, you'll see a clear message instead of a silent truncation.
Sessions start faster. Studio now handles chart-rendering setup before a session begins rather than during it, which noticeably reduces the time before you can start working.
Your prompts are better protected. Studio has expanded the masking of user-entered text in its analytics pipeline, so the content of your queries is not captured in usage data.
Error messages in the footer are now context-aware. The footer shows "click for details" when an error is collapsed and "click to hide" when it's open, making it easier to tell at a glance what action is available.
Fixes
Fixed an issue where switching between Dash Enterprise and Plotly Cloud authentication could leave stale settings behind, causing unexpected behavior until you logged out and back in.
Fixed a stuck "Loading…" state that appeared on sessions requiring credentials, and resolved a related issue where the credentials prompt didn't appear correctly when previewing an app.
Fixed intermittent delays and errors during chart export and code execution caused by unhandled edge cases in the rendering engine.

New Features
Skills
Skills are reusable prompts you run inside any agentic session to handle common tasks without retyping the same instructions. Nine built-in skills are available, and custom skills can be created additionally. Invoke any skill from the Skills panel or by typing its slash command directly in the prompt box.
Skills are great for spot checking your analysis, one-button creation for Dash apps, and even as a way to create a data source template when connecting to your data sources at the start of each session.
Start Sessions With Just a File Upload
You no longer need to write a prompt to start a session. Upload your data files and Studio will begin working from them. Session names also update automatically to reflect the names of your uploaded files.
Improvements
Redesigned session list. The session list now uses a cleaner layout that gives each session and its charts more room. The masonry grid has been replaced with a design that makes it easier to scan past work at a glance.
Smoother loading and startup. Loading animations in agentic mode are smoother, and startup errors now surface clear feedback instead of failing silently.
Navigation and account menu updates. The header has been reorganized and the user menu consolidates options, making team switching and account settings easier to find.
Fixes
Fixed an issue on Windows where Python processes would stay running after Studio closed, causing file locking errors on the next launch.
Fixed a bug where sessions could load stale data instead of the latest version.
Fixed spinner freezing during long operations.
Fixed an issue where Dash app code could render as plain text due to mismatched tags in the output.
Session thumbnails now show a placeholder when a chart image cannot be saved, rather than showing nothing.
Tables now match height correctly when displayed alongside charts.
Fixed terminology and interaction issues in the credential management UI.
Long prompts now collapse automatically in the input field.

Plotly Studio
New Features
Upload files during a session: You can now upload files at any point during a session, not just at the start. This makes it easier to bring in new data mid-analysis without restarting.
Sample sessions: When you first open Studio, you can now explore an example session while the backend loads in the background.
Fixes
Fixed a scrolling issue where submitted answers would briefly disappear. The "scroll to bottom" button is also no longer hidden behind the input field.
Fixed a Windows-specific issue where background processes continued running after an app update, which could prevent the app from restarting successfully.
