Release Notes

GPT-5.6 Sol, sign-in inside previews, and zero-config AI Gateway for generated apps What's new - GPT-5.6 Sol and a faster Sol Fast tier are available in the model picker, routed through OpenAI on Vercel AI Gateway, at 50% off through September 18. - Apps v0 generates connect to AI features through Vercel AI Gateway with zero-config authentication, covering text, structured output, embeddings, reranking, images, video, speech, and transcription, instead of asking you for provider or Gateway API keys. - Sign in with Vercel from inside a VM preview: the preview and the app share an origin so the session sticks, and sign-in opens in a new top-level window when the preview is embedded. - When a VM dev server fails to boot or install, a compact error bar appears beneath the preview and opens the console log to the exact error when you click it, and the preview keeps its navigation and retry actions in the error state. - Paid chats whose sandbox runs out of CPU or memory are moved up a VM size tier, and restarted in the background instead of timing out. - A "Team or password" visibility option lets a published app require Vercel team sign-in while still allowing access by password. - A new chat started inside a project begins from that project's own source, whether a GitHub branch, a managed repository, or the production deployment, so v0 has the code from the first message. - View revision history for your custom skills, including file paths, authors, timestamps, and text diffs. Bug fixes - The Pull Changes flow reruns the full preview pipeline and restarts the dev server, so dependency, config, and port changes no longer leave a stale preview. - Git auto-push is restored for chats on team-owned projects and for legacy project links that were failing with metadata-mismatch errors. - Git publish recovers when its tracked pull request was closed, moved, or fails to load, reopening or recreating it instead of failing repeatedly, and treats an already-handled post-merge rotation as success. - The publish popover keeps polling for deployment detail and streams live progress instead of getting stuck on Building until a reload, and no longer shows a red error tile on the first publish. - The Production Deployment card shows the selected custom domain for teams with a custom deployment suffix, and the publish flow falls back to a .vercel.app domain when a team's preview-suffix entitlement is off. - Sessions recover more reliably: an invalid or revoked token returns a clear sign-in error instead of a 500, SSO status refreshes when you return to the window, logging out revokes the session server-side, and a cookie-refresh race that could break auth is fixed. - Expired team SSO triggers reauthentication when you publish or open a project instead of surfacing a raw SAML error, and Open in v0 shows an actionable error when a linked GitHub base branch is missing. - Team upgrade and buy-more-credits tax estimates use the team's billing address, and paid scopes no longer see free-tier upgrade prompts. - Duplicate checkout requests are deduplicated so a subscription cannot be created twice, and you return to the chat you upgraded from after a plan change. - Enterprise-managed accounts keep their enterprise billing and gates when they have only team scopes, and a username that collides with a team slug no longer shows a paid team's balance as zero. - Starting a chat from the home composer reliably creates a new chat instead of queueing into the previous chat's stream, pasting into an unfocused composer no longer repeats the text, and removing an attachment cancels its in-flight upload. - Mid-response updates no longer make the task and deployment UI act as though streaming had ended, new sidebar rows show the generated chat title, and layout shifts in the chat header and preview popover on load are gone. - Generated images referenced by relative paths render in responses, as do screenshots with relative URLs, and Firefox no longer gets stuck in an infinite reload loop on affected Next.js dev versions. - Project icons are sourced from Vercel's avatar API again after the old favicon endpoint was removed, fixing letter-fallback icons across the sidebar, library, breadcrumbs, and settings. - Opening the design-mode font picker no longer corrupts fonts in the rendered app. - Figma integrations disconnect only on a confirmed invalid credential, so transient failures stop prompting a false reconnect, and Snowflake shows a retryable busy error instead of a misleading credentials prompt. - Actively used MCP connections stop forcing re-consent every 90 days by extending on use, and the Slack bot no longer posts a spurious "Request failed to complete." - Refocusing a backgrounded tab after a response finishes no longer leaves a stuck blank page, and search shows its loading state correctly. Misc. - Redesigned the settings surface. - Redesigned the header share popover into a centered Invite dialog you can open for any chat, with team sharing defaulting to edit and a View only switch. - Environment variable requests appear above the composer like questions and approvals, with collapse and reopen that keep the values you entered. - Git repository imports go straight to the chat instead of running detection and interrupting with a requirements modal. - Editor modes, Preview, Design, Code, and Database, have illustrated tooltips. - The maximum number of MCP servers per scope increased from 10 to 100. - Drag chats into Favorites in the sidebar, and the web-based code editor in the VM panel is available to everyone. - Download ZIP shows a native Save As dialog where the browser supports it. - The native mobile app gained message queuing, tappable links, shared-chat author avatars, and chat-history and image-caching improvements. - Sidebar polish: the main nav moved into the scrollable area, navigating to a project expands it, restricted chats show a lock on hover, and the Ch...
