A dated log of releases, retirements and research in computer use — every item with one source, and a plain statement of what it changed in the directory. Including, often enough, nothing.

Correction
Project Mariner appears to have shut down on 4 May 2026. It sat in this directory as a live research preview until today.
What it changed here: Project Mariner moved from Research preview to Superseded, and is flagged unconfirmed because no formal retirement notice exists. Its source label now says the vendor index no longer lists it.
Correction
The canonical repo is now a Rust harness based on Codex. The Python project continues as a community fork — under a different licence.
What it changed here: Open Interpreter's URL now points at the community fork, its licence is corrected from Apache-2.0 back to AGPL-3.0, and its description records the split.
Method
The first pass to check all 23 entries at once, in both directions. Here is everything it changed, including the things that make us look bad.
What it changed here: Every one of the 23 entries now carries a checked date of 8 October 2026. No date was advanced without an actual check.
Release
You subclass one and write a method per tool against your own automation. The loop everyone was writing by hand is now scaffolded.
What it changed here: Nothing. Toolset, surface and stage are unchanged; this is ergonomics, not capability.
Release
Dots are persistent agents in ChatGPT. Each gets a cloud computer and browser of its own, and keeps working after you close the tab.
What it changed here: Dots was added to the directory as a new entry, flagged secondary because openai.com refuses automated access.
Release
On Opus 5.5 and Sonnet 5.5, computer_20251124 returns a 400. The beta tool still works — just not on anything new.
What it changed here: Claude Computer Use keeps its GA stage; its profile now records that the older tool is rejected on the newest models.
Method
Google's always-on personal agent connects to Gmail, Drive and Calendar. Its own page does not claim it drives a browser or a computer.
What it changed here: Nothing. Recorded so the boundary is visible, and so the decision can be revisited if Google's documentation changes.
Release
The Mac app organises files, fills forms and works in Messages, Calendar, Notes and mail — with permission, and with approval before destructive steps.
What it changed here: Meta Muse was added as a new entry, surface Desktop, flagged secondary. Its watch-out records the unresolved question of whether it runs locally or in a cloud VM.
Release
Both toolsets reached Vertex the day after leaving beta, for all five supported Claude models.
What it changed here: Both Anthropic entries now record Google Cloud availability and the narrower coverage elsewhere.
Release
Computer use went GA as computer_toolset_20260801 with no beta header, and a separate browser use toolset launched the same day.
What it changed here: Claude Computer Use moved from Beta to GA in the directory, and Claude Browser Use was added as a new entry.
Retirement
Atlas stopped working on 9 August. ChatGPT agent was withdrawn in the same window. The capability did not disappear — it moved.
What it changed here: ChatGPT Agent moved from GA to Superseded, flagged as verified via secondary sources because help.openai.com refuses automated access. Operator's entry was rewritten to follow the lineage forward.
Infrastructure
Kitesurf drops tabs, themes and pixel-perfect rendering, runs in V8 isolates on Workers, and claims 3–7× less CPU and memory than Chromium.
What it changed here: Nothing. Kitesurf is a browser runtime, not an agent, and the directory lists agents.
Research
A confinement approach to cross-site prompt injection that constrains both what the agent sees and what it can do, with no per-site annotations.
What it changed here: Nothing directly. Recorded because it bears on the risk notes on every browser agent profile.
Release
An agent inside ChatGPT that takes an outcome rather than a task, gathers context across your apps, and returns finished sheets, slides, docs and web apps.
What it changed here: Nothing yet. ChatGPT Work is not listed, because its documented capability is producing deliverables rather than operating a screen. We will revisit if OpenAI documents it as driving a session directly.
Release
Public preview support in Gemini 3.5 Flash added built-in browser, mobile and desktop environments, configurable safety policies and prompt injection detection.
What it changed here: Nothing this pass. This is the source behind the Both surface and the Preview stage already recorded against Gemini Computer Use.
This vocabulary moves fast enough that a directory without a changelog is a directory that is quietly wrong. Four of the nine corrections in our last full pass were to the stage field alone — the one readers most reasonably assume is current.
So every change to the data is logged here with its source and its date, including the items that changed nothing. A news feed that only carries launches is a press release. The interesting entries are the retirements, and the releases that turn out not to matter.
