- DeprecatedClaude Sonnet 4.6
Deprecated across Copilot, with an exception for annual individual plans.
GitHub states Claude Sonnet 4.6 remains available to individual Copilot subscribers on annual plans so they retain a Sonnet offering; the deprecation does not apply to those customers. Replacement named: Claude Sonnet 5.

- DeprecatedGemini 3.1 Pro
Deprecated. Replacement named: Gemini 3.6 Flash.
Gemini 3.1 Pro was simultaneously one of only three models GitHub listed under visual work and one of six under deep reasoning — the comparison page was recommending it on the day it was retired.

- DeprecatedRaptor mini
Deprecated. Replacement named: MAI-Code-1-Flash.
The named successor is itself deprecated nine days later. Following the migration literally means moving twice; MAI-Code-1.1-Flash is the destination that survives both dates.

- ChangedTask groupings
Task groupings realigned to exactly the models GitHub places in each group.
This dataset previously assigned every Opus release to deep reasoning and every Flash release to fast work by inference. GitHub names five models under general-purpose and three under fast; 20 of 32 models sit in no group at all. A model GitHub does not place now carries an empty grouping rather than one this site inferred.
About this record
Every entry names the source it was read from and the date we read it. Nothing here is reconstructed from a version number or inferred from a release note we did not see — an unsourced changelog is a rumour feed, and this one is meant to be citable.
The record begins when this site started checking rather than when the product did. A backfilled entry is indistinguishable from an observed one once published, so there are none.
Corrections to our own datasets appear here too. When we get something wrong and fix it, that is a change worth recording for anyone who copied the earlier version.
