Code.org vs TAO Testing: at a glance
What is Code.org?
The rebrand is finishing while a challenge-evaluation subsystem quietly assembles.
Code.org ships a deploy log almost every weekday, and the codeai-next rebrand that flipped default in early August is down to its long tail: dialogs, hero art, icon colors, share panels. Two other threads run through nearly every deploy — image moderation wired into App Lab and Sketch Lab, and a challenge-evaluation model, job, and frontend arriving piece by piece. The remaining bulk of each entry is Playwright test ports, dependency bumps, and Kubernetes plumbing.
What is TAO Testing?
One feature, four branch tags — TAO's feed is backport plumbing, not release news.
Every entry in this feed is a backport. Three of the five tags carry the same change — the AUT-4590 dual preview feature and its flag — fanned across the v56.1, v56.3.1, and v56.3.5 construct lines, while the v55.0.1 line receives only dependency bumps. Release bodies are a PR reference and a version range; none describes what the change does for users.

The rebrand is finishing while a challenge-evaluation subsystem quietly assembles.
◆ Current state
Code.org ships a deploy log almost every weekday, and the codeai-next rebrand that flipped default in early August is down to its long tail: dialogs, hero art, icon colors, share panels. Two other threads run through nearly every deploy — image moderation wired into App Lab and Sketch Lab, and a challenge-evaluation model, job, and frontend arriving piece by piece. The remaining bulk of each entry is Playwright test ports, dependency bumps, and Kubernetes plumbing.
◆ Where it's heading
Two things are being built behind the rebrand noise. Moderation is being added everywhere a student can supply an image — URL moderation in App Lab, upload moderation and backpack-save blocking in Sketch Lab — which is the groundwork any classroom-facing generative feature needs. Challenge evaluation is landing in the order a graded, auto-assessed activity would require: model foundations, then a background job, then frontend and status, while Web Lab's preview traffic moves onto its own codeaiprojects.org domain.
◆ Prediction
Challenge evaluation should surface as a student- or teacher-facing feature within the next few deploys, and the Web Lab preview domain move has a stated part two still to land.
TAO Testing
2.5EDTECH
One feature, four branch tags — TAO's feed is backport plumbing, not release news.
◆ Current state
Every entry in this feed is a backport. Three of the five tags carry the same change — the AUT-4590 dual preview feature and its flag — fanned across the v56.1, v56.3.1, and v56.3.5 construct lines, while the v55.0.1 line receives only dependency bumps. Release bodies are a PR reference and a version range; none describes what the change does for users.
◆ Where it's heading
TAO is maintaining several customer-pinned construct lines simultaneously and moving work between them rather than shipping forward on a single trunk. The version numbers run non-monotonically as a result — v55.0.1.13 is newer than v56.3.5.2 by date — so tag order says nothing about what a given release contains. Nothing here indicates development on new capability.
◆ Prediction
Expect more per-branch backport tags with contentless notes as features already merged upstream are pulled into supported lines. Whether dual preview reaches the v55 line is not visible from these entries.
