Frequently asked questions
How often is this timeline updated?
It's updated as major new flagship or notable mid-tier models are released — see the last-verified date at the top. It focuses on major releases from OpenAI, Anthropic, and Google rather than every minor update or regional rollout.
Why does the pace of releases look like it's accelerating?
Major AI labs have genuinely shortened their release cycles — early entries in this timeline are roughly a year apart, while recent ones are weeks apart, reflecting real competitive pressure across the industry, not just more entries being tracked.
Does a later release date mean a strictly better model?
Not necessarily — a later date means newer, but 'better' depends on the specific task and which tier (budget, balanced, flagship) is being compared. See the AI Model Comparison tool for current capability and pricing tiers side by side.
