Notion's sixth-generation agent harness stretches task runtime from five minutes to 24 hours

A rebuilt agent infrastructure, computer and browser access, and an upgraded Auto router that Notion says cuts average inference cost by about 90% remove the biggest practical ceiling on what a small team can delegate overnight.

Notion on October 19 rebuilt the infrastructure behind Notion Agent and Custom Agents, lifting the ceiling on a single autonomous task from five minutes to more than 24 hours. Co-founder Akshay Kothari calls the sixth generation of the harness “more powerful, more reliable, and more efficient,” which is corporate for: the old one couldn’t do the work customers were already trying to make it do.

The five-minute cap was the real story under the story. It quietly disqualified every job a five-to-thirty-person company actually wants delegated: overnight prospect research, a week of draft content, a competitive sweep. Notion says more than a million Custom Agents have been created since the broader agent push began, which reads less like a milestone than like evidence of pent-up demand running into a wall.

The new harness pairs the longer runtime with browser access, a built-in computer Notion claims is faster and cheaper than spending model tokens on the same work, and an upgraded Auto router. Across more than 20 common use cases, Notion says Auto matches Opus 5.5 and Astra at roughly 90% lower average cost, stretching credits about ten times further. Agents run up to 50% faster on web and mobile. Custom Agent runs cost about 30% less in testing. Uptime, the company reports, sits above 99.9%.

Economics matter here because they decide whether this is enterprise theater or small-team infrastructure. A 24-hour run that burns a month of credits isn’t usable; one that doesn’t is.

Seven new models from Anthropic, OpenAI and open-weight providers landed in the past month, and tool connectors have gone from a few dozen earlier this summer to hundreds via MCP. Safety got Plan Mode and a “Review for me” step. A new two-pool credit system, 1,500 Standard and 500 Select for Business and Enterprise seats, hits new customers today and existing workspaces on November 2.

The competitive geometry is now legible: Copilot embedded as the default OneDrive brain, Gemini turned into a workplace agent across Workspace, and Notion betting that the surface people already write inside is where the overnight work gets queued.
