Notion on October 19 announced a rebuilt foundation for its AI agents, which it calls its sixth-generation agent harness. According to Notion’s release notes and blog post, agents can now work on a single task for up to 24 hours. One report puts the previous limit at about five minutes.
What changed in the agent
Notion says each agent session now runs on a dedicated service with a queue-backed worker loop, designed so that work continues through restarts. Agents also get their own computer and browser, and the company describes improved context management: long conversations are compacted, and large tool results are offloaded rather than kept in the model’s context window.
A new “Review for me” mode adds safety checks, according to the release notes. Notion has not published independent benchmarks of the new harness, so the long-running claims come from the company itself.
Auto router and credits
Alongside the harness, Notion upgraded Auto, its model router. The company says Auto delivers results comparable to frontier models at about 90% lower average cost. That figure is Notion’s own claim and may not hold for every workload.
Notion also introduced a new AI credit system. Per the announcement, it applies to new workspaces now and to existing workspaces on November 2. Users can connect a ChatGPT Plus, Pro or Go plan to the personal Notion Agent, while bring-your-own-key for enterprises is in private alpha. An AI Command Center for administrators is listed as coming soon.
Why it matters
Longer-running agents shift workspace tools from answering prompts toward completing multi-step work unattended, which raises the stakes for review controls and cost predictability. Notion’s pairing of a long-horizon harness with a cost-optimizing router and credit billing reflects a wider push to make agent usage affordable at scale. How the credit system affects what teams actually pay after November 2 is the thing to watch.
