June 10, 2026

Claude Fable 5 & Supabase integration

Anthropic's most capable model is now generally available in the model picker, and a new one-click Supabase integration unlocks your database, edge functions, and project management inside Viktor.

  • Claude Fable 5 — Anthropic's most powerful model graduates from early access to general availability. Select it in the model picker when you need peak reasoning — it runs at 2× Opus pricing and includes automatic Vertex provider fallback for extra reliability under load.
  • Supabase integration — Connect your Supabase project with one-click OAuth and give Viktor 20+ native tools covering table CRUD, the Management API, migrations, edge functions, log inspection, and TypeScript type generation — no API keys to paste, no project refs to look up.

Workspace personalization settings

Set a personality and custom instructions that shape how Viktor responds across your entire workspace.

  • Workspace personalization — A new section in Settings lets you pick a personality preset and write custom instructions that apply to every Viktor conversation in your workspace. Use it to adjust tone, set standing context ("we're a B2B SaaS company", "always reply in Spanish"), or reduce sycophancy — the instructions are injected into Viktor's system prompt so they take effect immediately, no restart needed.

Claude Opus 4.8

Anthropic's latest frontier model is now available in Viktor's model picker.

  • Claude Opus 4.8 — Anthropic's newest flagship model is now available in the model picker for all workspaces. Select it when you need maximum reasoning depth — it uses adaptive thinking that scales compute to match problem complexity.

Read-only GitHub integration

Connect GitHub in read-only mode so Viktor can browse repos, issues, and PRs without write permissions.

  • Read-only GitHub integration — A separate read-only GitHub connection is now available alongside the existing read-write one. Connect it when you want Viktor to browse your repos, review code, and read issues or PRs without granting write access — useful for security-conscious teams or when full repo access isn't needed.

Redesigned Spaces page

Spaces are now displayed as thumbnail cards with direct app-launch buttons and a grid / list view toggle.

  • Redesigned Spaces page — The /viktor-spaces page now shows each space as a thumbnail card instead of a flat list. You can launch production or preview apps directly from the card without entering the management page first. A grid / list toggle in the header lets you pick your preferred layout — the choice persists across sessions.
May 19, 2026

Media generation chart on the Usage page

A new chart on the Usage Overview shows all your image, audio, and video generation usage in one place — click to drill down by media type.

GPT-5.5, Bigger Claude Outputs & a Refreshed Usage Page

GPT-5.5 joins the model picker, Claude Opus and Sonnet can now produce much longer outputs, the signup page tells you exactly what you're about to install, and the Usage page gets a Scheduled Tasks tab and per-user usage stats.

  • GPT-5.5 in the model picker — OpenAI's newest model is now available for selection across coworker tasks. Kimi K2.6 and Gemini Flash 3 have been retired from the default-model picker.
  • Longer Claude outputs — Output caps for Claude Opus 4.6 / 4.7 and the Sonnet 4 family were raised significantly, so Viktor can now return much longer reports, drafts, and analyses in a single response without truncation.
  • "You're installing X" on signup — When a logged-out user clicks Install on a skill or bundle, the signup page now shows exactly what's being installed, so the install intent survives the sign-in handoff and lands you straight into the right setup.
  • Refreshed Usage page — The Usage settings now include a Scheduled Tasks tab listing every running scheduled task in one place, plus per-user usage stats so workspace admins can see exactly which teammates are spending credits and where.

Google Ads Negative Keywords & Smarter Slack Replies

Manage Google Ads negative keywords from Viktor, and get DM replies that stay in thread with quick status acks.

  • Google Ads negative keywords — New tools to list, add, and remove negative keywords at the campaign or ad-group level, with batch updates and match-type support, so you can prune wasted spend without leaving Viktor.
  • Slack DM replies stay in thread — When you DM Viktor about a specific channel thread, replies now land back in that same thread instead of bouncing to the channel root.
  • Quick acks on status checks — If you ping Viktor mid-task to ask where things stand, you'll get a short Slack status update first before it resumes the work.
April 27, 2026

Pause & Resume Scheduled Tasks

Pause any scheduled task and resume it later — without losing the schedule or rebuilding the cron.

  • Pause & resume controls for scheduled tasks — You can now pause any scheduled task from settings and resume it later. Paused tasks persist across runs and skip their scheduled execution until you turn them back on, so you can quiet a noisy cron without deleting and rebuilding it. The same controls are available to agents, the SDK, and flow APIs.
April 23, 2026

Per-Model Reasoning Controls & GPT-Image-2

Pick reasoning effort per model, choose defaults from a redesigned grid, and generate sharper images with OpenAI's newest model.

  • Per-model reasoning controls — The Default AI model settings page is now a redesigned card grid where you can pick a reasoning effort (Minimal, Low, Medium, or High) for each model, so you can tune depth vs. speed for how you actually work.
  • GPT-Image-2 as the default image model — Image generation now uses OpenAI's newest gpt-image-2 by default, with better fidelity and more accurate token-based cost accounting.
April 22, 2026

Reconnect Integrations, Smarter Approvals & Kimi K2.6

One-click reconnect for broken integrations, always-approve for trusted tools, a softer past-due experience, and a new Moonshot model.

  • One-click reconnect for broken integrations — The integrations page now flags broken OAuth connections with a clear status and lets you reconnect in place. Your row-scoped settings are preserved, so you don't have to reconfigure Meta Ads, Google Ads, Stripe, Linear, Granola and others from scratch.
  • "Always approve this tool" in Slack — When Viktor asks for permission to use a tool in Slack, you can now choose to always approve future uses of the same tool. The preference is saved to your MCP settings so you stop getting re-prompted for tools you trust.
  • Atlassian pre-connect setup guide — Connecting Jira or Confluence now walks you through the steps your workspace admin needs to take first (whitelisting the Rovo MCP domain) before the OAuth flow kicks in, so the connection works on the first try.
  • Moonshot Kimi K2.6 available — Moonshot's newest Kimi K2.6 model is now selectable in the model picker (marked "in testing") alongside the existing frontier models.
  • Clearer account deletion for admins — When you're the last admin deleting a workspace, Viktor now shows exactly which teammates will lose access and how many scheduled tasks each person has, so you know the impact before you confirm.
  • Softer past-due experience — If a payment fails, you'll now see a banner at the top of the app instead of a full lockout. You can keep browsing your usage and settings while the payment recovers.

  • External shared channel → DM handoff — When Viktor is @mentioned in a Slack Connect channel, it now moves the conversation into a private DM instead of replying publicly.

  • Auto-resume after integration connect — When Viktor asks you to connect an integration and you complete the OAuth flow, it now automatically picks up where it left off. No more having to manually say "I've connected it" — the conversation continues seamlessly.

Channel Selection & Personalized Skills

Pick which Slack channels Viktor joins during setup, and each team member now gets their own personalized skills.

Slack Channel Privacy

  • Slack channel privacy — When multiple people share a Viktor workspace, each user's agent now only sees the Slack channels they're actually a member of. Private channels, DMs, and group DMs stay private — matching the access rules you already have in Slack. Access updates automatically when someone joins or leaves a channel.
  • Create group DMs — You can now ask Viktor to start a group DM with specific people directly — no approval step needed.

Group DMs, Custom Sender Names & Channel Controls

Viktor now works in group DMs, scheduled tasks can post under custom names, and you can ask Viktor to leave channels.

  • Custom sender names for scheduled tasks — Scheduled tasks can now post messages under a custom display name instead of always appearing as "Viktor."
