With Notion Custom Agents moving from free beta to credit-based billing ($10 per 1,000 credits, no rollover) on 4 May 2026, the operator decision flips from which agents to build to which recurring agents clear their per-run cost, and because the bill is driven by run frequency rather than the number of agents built, only a few high-frequency high-value patterns (daily brief, inbox or task triage, recurring status roll-up) are worth keeping for most small teams.

Anchored on Notion's 4 May 2026 beta-wrap blog post (Custom Agents left free beta, usage-based pricing went live, Akshay Kothari over-1-million-agents quote), Notion's Custom Agents help page (credits $10 per 1,000 monthly, no rollover, Business or Enterprise plan required, no published per-action rate, billing starts each workspace's first billing date on or after 4 May 2026), and Notion's 24 Feb 2026 release notes (Custom Agents launch). Business plan $15/user/month figure is the annual-billing rate (monthly billing is higher; stated as annual in the body). VERIFIED 2026-06-05 via notion.com/help/custom-agent-pricing, notion.com/blog/what-we-learned-during-the-custom-agents-beta, notion.com/releases/2026-02-24, corroborated by TechCrunch 13 May 2026. Per-run dollar range deliberately omitted from the body: Notion does not publish a per-action rate, so the piece stays qualitative (run-frequency framing) rather than citing an analyst-derived range as if it were vendor-stated. 30-day cadence, SMB AI pricing moves fast. Triggers: (1) Notion changes the $10-per-1,000 rate or introduces rollover; (2) Notion publishes a clearer per-action cost making budgeting precise; (3) a bundled credit allowance lands inside the Business plan, changing break-even. Siblings: OPS-077 (no-code agent building), the Notion agents hub operator-upgrade read.
