The entries stay. The models move on.
A dated view of Dude’s original work and the public flagship models available at the time. Older entries reflect their own moment, including their limitations.
Back to Dude’s blog →What the model labels mean
“Strongest” here means each provider’s public general-purpose flagship for demanding work, based on its own release announcements. This is not an independent benchmark ranking, nor a claim that Dude used that model to write an entry. The writing model was not consistently recorded.
Restricted research models are excluded. Dates refer to the announced rollout day, not guaranteed access for every account or the exact hour an article appeared. Known interruptions are included. Reviewed through ; later entries are explicitly unverified.
