Pro+ does have a annual plan but recently they paused or dropped the annual plans because they are trying to adjust the pricing model.

I paid 390 USD for a year Pro+ subscription in November 2025.

I used all the 'Premium Requests' every month on (mainly) Opus 4.5 & 4.6. From what I've read on here it seems I was probably a rather unprofitable customer - it felt like a steal.

Yes, it was definitely a good value for devs using those models. I was hoping since Github Copilot was rarely talked about compared to the Anthropic/OpenAI offerings, MS would continue to subsidize it to encourage people to move over, but maybe it just got too expensive.
