The company says agents can now work on a single task for more than 24 hours, up from five minutes. It also says ChatGPT Plus, Pro, and Go plans can be connected to personal Notion Agent, while Custom Agents are not included in this initial connection.
The implication is that runtime persistence and model access are becoming distinct product decisions: longer execution does not itself establish that an agent reliably finishes useful work. Notion’s announcement also reports 30% lower Custom Agent run costs in testing and more than 99.9% infrastructure uptime; these are company-reported figures, not an independent evaluation.
Thesis
For production agents, the harness is becoming a more durable product boundary than the identity of the model running inside it.
Observed facts
Notion says agents can now work on one task for more than 24 hours, compared with five minutes previously.
1Notion says ChatGPT Plus, Pro, and Go plans can connect to personal Notion Agent; Custom Agents are excluded for now.
1Notion describes a dedicated service with a queue-backed worker loop designed to continue work through restarts and hiccups.

Mechanism
Notion attributes longer sessions to a dedicated service with a queue-backed worker loop that continues through restarts and hiccups, alongside context compaction and offloading large tool results. The access connection is separately scoped to personal Agent, rather than all agent surfaces.
Why now
Notion says it has added seven models in the past month and presents these changes as a response to users treating the workspace as infrastructure for their own agents.
Implications
The implication is that runtime persistence and model access are becoming distinct product decisions: longer execution does not itself establish that an agent reliably finishes useful work.

Evidence boundary
Evidence boundary: The source is Notion’s own product announcement, and it does not provide independent measurements or a full account of task success.
Watch conditions
What to watch: Whether Notion extends the ChatGPT connection to Custom Agents and publishes evidence on completion quality for long-running tasks.
