Plans and quotas - Cortex Docs

Your plan, today’s usage, and the reset timers live under Settings → Plan & billing. The product is the source of truth for numbers; this page explains what each plan is for and how limits behave.

Plan & billing — Free, Go, Plus, and Pro plan cards with their features — Settings → Plan & billing. The plan ladder as shown in the product; the Change plan buttons are marked Coming soon while checkout is being finished.

The plans

Plan	Price	Who it is for	Includes
Guest	—	Anyone before signing in	A daily and monthly message allowance; conversations live in the browser session
Free	$0 / month	Everyday tasks	Limited messages each day and month · Cortex 1 Mini · web search and code runs · image generation with Cortex-Image-1 · written conversations, subject to abuse protection
Go	$8 / month	Everyday work	Everything in Free · more messages each day and month · priority when the fleet is busy · extended memory and context

Plus is the recommended plan in the product. Switching takes effect at the next billing cycle. At the time of writing the Get Free / Go / Plus / Pro buttons and Billing history are marked Coming soon; the ladder above is what the product lists.

Usage and reset timers

Settings → Plan & billing shows today’s and this month’s message counts with a reset countdown for each window.

Guest plan usage — messages today 0 of 100, messages this month 0 of 500, with reset timers — A guest's usage: 100 messages today and 500 this month, each with its own reset timer.

How limits fail

Cortex quotas fail closed: when a window is used up, the product says so and tells you when it resets. Nothing is silently downgraded, and there is no paywall pretending to be a quota.

What happened	Error code	What to do
You used the window for today or this month	`quota_exceeded`	Wait for the reset shown in the product, or move to a plan with higher ceilings
The plan does not include the capability at all	`entitlement_required`	That capability is not on this plan
Too many requests in a short burst	`rate_limited`	Retry after the pause the product suggests
The fleet is at capacity	`no_capacity`	Try again shortly; Go and above get priority when the fleet is busy

Image generation on Free and Guest is metered as images_per_day. Running out is quota_exceeded, not a paywall. See Image generation. The CLI shows the same thing in the terminal: when the agent quota is exhausted the composer is held with the reset time, and /usage shows the details. See CLI troubleshooting.

Model availability

Model availability depends on your plan. During peak hours new chats may fall back to a faster model; the composer chip always shows which model is serving the conversation. See Models.

Frequently asked

Does unused quota roll over?

No. Daily and monthly windows reset on the timers shown in Plan & billing.

Was there a Pro trial?

Through 7 September 2026 a signed-in member could claim one month of Cortex Pro from the product. That window has closed; claiming twice never stacked.
