New features
Compare up to 8 models per generation — The per-generation model cap doubled from 4 to 8, so you can line up more side-by-side comparisons in a single run. This applies uniformly to image and video, and the landing page picker now supports multi-select for video too. See multi-model generation.Stacked session workflow by default — New sessions now open in the stacked layout, putting your generation surface, gallery, and chat in a single coherent view. Learn more about working in sessions.Archived chat tabs in every session — You can keep parallel chat explorations alongside your work. Each session now supports multiple chat tabs that auto-name themselves from your first message, so threads stay organized as you branch ideas. See sessions for details.Voice dictation in chat — Speak your prompts directly into the chat input. The new dictation flow transcribes on the fly so you can ideate without typing.Reasoning effort control for chat — A new pill on the chat composer lets you set reasoning effort to Off, Low, Medium, or High. Higher levels give you deeper assistant reasoning when you need it; lower levels keep things snappy. Your choice is remembered per browser. See the prompt assistant.Image edit toolbar (Phase 1) — A new in-canvas toolbar adds crop, split-grid, and download actions directly to your generated images, so quick edits no longer need a round trip to another tool.Free trial support — New users can start a free trial to try premium features before picking a plan. See plans for what’s included.Cross-device preferences — Generation preferences (model, aspect ratio, video defaults, and more) now sync to your account, so your setup follows you between devices. See settings.In-app notifications — A new notification broadcast system delivers product updates and important account messages directly inside the app.Updates
Inline outpaint controls — Outpaint now lives on the canvas surface with a slider, directional arrows, prompt input, and generate/cancel controls — replacing the old drag-handle popover for a more direct editing experience.New Mux video player — Video playback was rewritten on the official Mux player, giving cleaner autoplay, posters, and interaction handling, plus fewer console errors. See the video generation guide.GIF size preference — A newgifMaxSizeMB preference lets you control output file size for animated thumbnails by tuning maximum frame count. Manage it from your generation settings.Image-first gallery — The persistent model badge on each card was moved into a hover toolbar, paired with the provider icon. The masonry grid was also tightened so artwork leads, not labels.Auto-named chat tabs — Chat tabs now derive a 3-word title from your first message, making it faster to scan parallel threads.Streamlined generation toolbar — Model selector ordering was prioritized for the most-used controls, and the input scroll area was reworked so long prompts no longer push the toolbar around.Bug fixes
- Toolbar text bleed-through — Long prompts no longer leak visually behind the model selector and settings pills.
- Outpainted images in history — Outpainted results now render correctly in the generation history view.
- Session intro prompt flicker — Fixed a race where the intro prompt could be wiped mid-stream while chat tabs were still resolving.
- Assist image plan ratios — Malformed aspect ratios from the assistant are now handled gracefully instead of failing the plan.
- Prompt history & local sessions — Prompt history linkage and local auth sessions are now preserved correctly across sign-ins.
