Code completions are the completions when you edit directly in the code editor, it will then give you code suggestions. With the free plan you get a maximum of 2000 suggestions per month.
For the chat, which is used for the AI Assistant you can do 50 messages per month. There is no token limits.
The 90000 token limit is the maximum that the selected model accepts for the prompt, the output is limited to something like 4096 or 8192 tokens. The full context window of the models are often even bigger.
Sometimes when I am working in code view I get code suggestions in grey text. Is that from the AI assistant? I notice sometimes it is pretty clever. If I wanted to use that suggested code how would I do that?
Thanks again, I have so much to learn about this AI stuff.
