Perch Ultra
No 5-hour limit. Three times the room.
Ultra is $30 a month: everything in Pro, three times the weekly room, and Claude Fable 5.1 and GPT-6 Astra.
No 5-hour limit
Long agent runs, parallel chats and helper agents keep going. No 5-hour window pauses you mid-task on either usage lane; the weekly and billing-period limits are the only walls, so a whole week's amount is there in one sitting if the work needs it.
Three times the room
Roost allows 60,000 PT per rolling 7 days, against Pro's 20,000, with no fixed monthly cap. Picking models by hand allows $112.50 per rolling 7 days and $225 per billing period, against Pro's $37.50 and $75. A notice appears at 50% and 80% of each weekly limit.
Two models only Ultra can pick
Claude Fable 5.1, with a 1M-token context window, and GPT-6 Astra, with 1.05M. Both write up to 128K output tokens. You pin them by hand; Roost never chooses them. They draw from Ultra's manual allowance like every other pinned model.
Coming from Pro
Same subscription. Bigger limits once the difference is paid.
Moving up keeps your subscription and billing date. The prorated difference for the rest of the current billing period is charged right away, and Ultra's limits apply as soon as that payment succeeds. Usage you have already spent this period counts toward the bigger limits.
To go back, choose Switch to Pro at renewal in Settings → Billing. Ultra stays active until your next renewal, then Pro continues at its $10 price. Until then you can choose Keep Ultra. Coming from Starter, Ultra is a normal checkout, like Pro.
Questions
Before you upgrade.
- What does Ultra add over Pro?
- No 5-hour limit, three times Pro's weekly limits on both usage lanes and three times its billing-period allowance for manual model selection, plus Claude Fable 5.1 and GPT-6 Astra. Roost allows 60,000 PT per rolling 7 days with no fixed monthly cap. Manual model selection allows 112,500 PT per rolling 7 days and 225,000 PT per billing period. A notice appears at 50% and 80% of each weekly limit. Everything else matches Pro.
- What happens when I reach a weekly limit?
- That usage lane pauses until enough earlier usage is more than seven days old, so a used-up week frees gradually rather than all at once. Roost and manual model selection have separate limits, so reaching one leaves the other available. If the 225,000 PT manual allowance for the billing period runs out, switch back to Roost or wait for the next billing period.
- Can I switch between Pro and Ultra?
- Yes. Moving from Pro to Ultra keeps your subscription and billing date: the prorated difference for the rest of the current billing period is charged right away, and Ultra's limits apply as soon as that payment succeeds. To move back, choose Switch to Pro at renewal in Settings → Billing; Pro starts at your next renewal at its $10 price, and until then you can choose Keep Ultra to stay.
- Is any Ultra data handled differently?
- Claude Fable 5.1's host keeps prompts and replies for up to 30 days and may have people review them for safety. Security and data explains how Perch handles model requests. Ultra activity is excluded from the Starter Data Program, like Pro.
- Can I cancel Ultra?
- Yes, from Settings → Billing. Ultra stays active through the period you already paid for, then the account moves to Starter. Perch does not charge usage overages.
- Does Ultra include direct API access?
- No. Like Starter and Pro, Ultra includes Perch-hosted model usage through Perch AI Web, Desktop, and CLI. You can bring your own API key on any plan, and usage you pay your provider for does not count against Ultra's limits.
Every limit and billing detail is in the Ultra plan guide. To see Ultra beside Starter, Pro and Enterprise, compare plans.
