Gemini 3.8 Flash and DeepSeek V4.1 Flash on every plan
Whether the one-time free trial reaches each model, then each paid plan's messages on it.
| Plan | Price | Gemini 3.8 Flash | DeepSeek V4.1 Flash |
|---|---|---|---|
| Free | $0 | Not in the trial | Not in the trial |
| Plus | $10 a month | Up to 125 a month | 30 a day |
| Pro | $20 a month | Up to 250 a month | 60 a day |
| Max | $50 a month | Up to 800 a month | 120 a day |
| Ultra | $100 a month | Up to 1,800 a month | 200 a day |
| Studio | $200 a month | Up to 4,000 a month | 200 a day |
Prices don't include tax, which is added where it applies and shown before you pay. A paid plan's month is one allowance shared by every model, so each monthly count is the most you get if all of it goes to that model. It renews each billing period; everyday models refill daily at 00:00 UTC. Long chats count more per reply. How pricing works.
Every limit is published. Paid plans also have a monthly fair-use limit on AI cost: Plus $3.75, Pro $7.50, Max $20, Ultra $42, Studio $85. Using every message on your plan at typical sizes stays under it; very large messages and heavy research use it faster. Every limit, explained.
