Brilliant vs TAO Testing: at a glance
What is Brilliant?
Brilliant launches Koji, a graphical AI tutor — its first product move in 15 months.
Brilliant ships infrequent, essay-style blog posts that read as much like product manifestos as changelog. The most recent post announces Koji, framed as a graphical AI tutor — the first new headline product in this ten-entry window. The rest of the timeline is course-design philosophy around algebra, programming, and learning-game evals.
What is TAO Testing?
TAO opens the 56.15 line with a database index while patching a bad migration on three branches.
TAO's core cut 56.15.0, whose only listed change adds a database index for ReadonlyLiteral properties. On the same day it shipped 56.14.11, 56.14.8.1 and 56.13.1.3, each deprecating a bad migration on its branch. Earlier October releases were single-fix 56.14 patches on Resource Manager and task logging.

3.8EDTECH
Brilliant launches Koji, a graphical AI tutor — its first product move in 15 months.
◆ Current state
Brilliant ships infrequent, essay-style blog posts that read as much like product manifestos as changelog. The most recent post announces Koji, framed as a graphical AI tutor — the first new headline product in this ten-entry window. The rest of the timeline is course-design philosophy around algebra, programming, and learning-game evals.
◆ Where it's heading
The throughline across these posts is the same: lean on visual, game-like interaction and use AI to scale the tutor-style feedback loop the team keeps writing about. Koji is the first concrete productization of that thesis after a long stretch of essays describing the approach. Cadence remains slow, which suggests Brilliant publishes only when something is meaningfully different.
◆ Prediction
Expect Koji to roll out across more subjects following the same algebra-then-CS pattern earlier posts described, and for future entries to attach Koji-specific course launches rather than announce new products from scratch.
TAO Testing
5.0EDTECH
TAO opens the 56.15 line with a database index while patching a bad migration on three branches.
◆ Current state
TAO's core cut 56.15.0, whose only listed change adds a database index for ReadonlyLiteral properties. On the same day it shipped 56.14.11, 56.14.8.1 and 56.13.1.3, each deprecating a bad migration on its branch. Earlier October releases were single-fix 56.14 patches on Resource Manager and task logging.
◆ Where it's heading
The project is still in maintenance mode ahead of its 2026-11 LTS, and the migration fix backported to three branches shows it supports several release lines at once. Opening 56.15 with a performance index instead of features suggests the LTS may be cut from the new line.
◆ Prediction
Expect more single-fix patches across 56.13–56.15 and then the November LTS. The entries don't show which line the LTS will be based on.
