API billed per token, separate bill.
Free plan
Yes - permanent free tier with unlimited everyday text chat, but ad-supported and with separate caps on uploads, images, voice and research.
Free trial
No standalone free trial of Plus/Pro; the free tier serves that purpose. Business trials are handled through sales.
Usage limits to consider
Free and Go have capped uploads, image generation, voice, deep research and memory. Plus uses a rolling message cap resetting every few hours plus a weekly cap on extended-reasoning messages. Pro is 'unlimited subject to abuse guardrails' with no published cap. Context tops out around 128K instant / 400K reasoning tokens on Pro.
