Frequently asked questions

Is Claude 3.5 outdated?

It's older than 3.7/4 but still very capable for everyday questions, and it's free to use here.

How does it compare to ChatGPT 4o?

They're similar in quality on common tasks. Claude 3.5 tends to write longer, more structured responses; 4o is faster and more conversational.

Why use 3.5 instead of 3.7?

3.5 is on the free tier — it costs no extra credit multiplier. Pick it for casual or unlimited use.

Will Claude 3.5 stop working someday?

Eventually, yes — Anthropic will deprecate older versions. We'll switch this page to a successor when that happens.
