What is Notion?

Notion is building the place where other companies' agents come to work

The 3.5 and 3.6 releases turned Notion into a developer platform: Workers run custom code on Notion's infrastructure, a CLI and Markdown API exist for coding agents, and External Agents bring Claude and Cursor onto a shared board where a team can assign and watch them. Custom Agents have accumulated the surrounding machinery in the weeks since — five more MCP connections, calendar tools, Outlook mail, Microsoft file read and write, audit-log coverage, and a people directory. The most recent entries are smaller and mostly about wiring: sharing context from the Share menu, sharing Workers across a team, and surfacing Worker usage in the credits dashboard before the free beta ends.

What is opus?

Opus put neural networks inside the codec, then pushed the sample rate to 96 kHz.

Opus is at 1.6.1, a small fix release on top of 1.6. The two releases that matter in this window are 1.5, which made the first extended use of machine learning in the encoder and decoder through Deep Redundancy and Deep PLC, and 1.6, which built on that with a wideband-to-fullband bandwidth extension module, 96 kHz support under the Opus HD name, and a 24-bit API. Between and around them sit build fixes and checksum-only patches.

Notion is building the place where other companies' agents come to work

◆ Current state

The 3.5 and 3.6 releases turned Notion into a developer platform: Workers run custom code on Notion's infrastructure, a CLI and Markdown API exist for coding agents, and External Agents bring Claude and Cursor onto a shared board where a team can assign and watch them. Custom Agents have accumulated the surrounding machinery in the weeks since — five more MCP connections, calendar tools, Outlook mail, Microsoft file read and write, audit-log coverage, and a people directory. The most recent entries are smaller and mostly about wiring: sharing context from the Share menu, sharing Workers across a team, and surfacing Worker usage in the credits dashboard before the free beta ends.

◆ Where it's heading

Notion is positioning itself as the orchestration layer rather than another agent vendor, which is a different bet than most of its competitors are making. The supporting work is consistent with that: Workers to run the code, a credits dashboard to price it, an audit log to govern it, and sharing so one person's Worker becomes a team asset. The recent shift from platform launches to permissions, sharing and billing surfaces is what a product does after the capability lands and adoption becomes the constraint.

◆ Prediction

Workers move onto paid credits on August 11, so the near-term work should keep clustering around usage visibility and cost controls. The trigger surface is the other thread to watch — meeting notes became an agent trigger this window, and the same pattern applied to other Notion events is the obvious next step.

0.0

Opus put neural networks inside the codec, then pushed the sample rate to 96 kHz.

◆ Current state

Opus is at 1.6.1, a small fix release on top of 1.6. The two releases that matter in this window are 1.5, which made the first extended use of machine learning in the encoder and decoder through Deep Redundancy and Deep PLC, and 1.6, which built on that with a wideband-to-fullband bandwidth extension module, 96 kHz support under the Opus HD name, and a 24-bit API. Between and around them sit build fixes and checksum-only patches.

◆ Where it's heading

Opus is moving in two directions that would once have looked contradictory: reconstructing audio that was never transmitted, via ML-based redundancy and loss concealment at very low bitrates, and carrying far more of it, via 96 kHz and 24-bit paths. Both extend a codec whose IETF-standard core has been frozen for years, by adding layers around it rather than changing the bitstream everyone already decodes.

◆ Prediction

With 1.6.1 confined to minor fixes and the bandwidth-extension module newly landed, the next releases are likely to tune and optimize the existing ML modules rather than add another.
