Late last year was like 3 months ago.
I'm bullish on Claude. It will see a surge in users, and will likely surpass Perplexity this year. However I don't think it will catch up to even Meta AI (which had 10x the number of users) this year.
I’m aware of how long ago late 2025 was.
Anthropic’s revenue in Q1 2026 has skyrocketed.
I use Claude. I use Codex. I've never heard of or used Meta AI. Nor do I have a Facebook account. Never have, never will.
I am also a software developer. So while the numbers of "people" that use one AI or another may be higher than either of these, it's not a useful metric for myself.
