Plan usage

Every plan includes usage of Quant, our coding agent, and the Strategy Screener. Plan usage is measured over two windows, a 5-hour session and a week, and both refill on their own. On a paid plan, extra usage keeps you going when plan usage runs out.

Over a month, every paid plan includes at least 3× the Quant it did on monthly credits, and Free far more. Prices are unchanged. Read the announcement: More Quant on every plan.

How it works

• The session. Your first message starts a 5-hour session. Session usage refills 5 hours after the session started.
• The week. Weekly usage resets for everyone every Friday at 5:00 PM ET, shown in your own time zone.
• One pool. Quant and the Strategy Screener draw from the same plan usage.
• Usage follows the request. Bigger requests and longer conversations use more, because the whole conversation is context for every new message, so start a new chat when you move to an unrelated script.
• Compile fixes don't count. Compile errors Quant fixes in the same reply don't count toward your usage.
• Plan changes. When you subscribe or change plans, your limits follow the new plan. When a paid plan ends, they drop to Free's.

Your session and weekly usage, with when each resets, are on the Usage page of your account (app.luxalgo.com/account/usage). Your plan is on the Plan & Usage page (app.luxalgo.com/account/plan).

Big builds

Before a big build, Quant shows a plan: the parts it will write, about how many lines, and about what share of your session and week it will use.

• When Quant waits. If a build would use 10% or more of your session, or 5% or more of your week, Quant waits for Build it or Make it smaller. Smaller builds start right away, at full size.
• A live checklist. While Quant works, a checklist ticks off each part as it compiles.
• Split scripts. A build too big to load quickly as one script is split into a few.

Not charged and paused replies

A line under a Quant reply tells you when it wasn't charged or why it stopped:

• Not charged: Quant hit an error before answering. The message didn't count toward your usage.
• Paused to check in. Continue to keep going. On a long reply, Quant stops to check in. Its work so far is kept. Click Continue to pick up where it stopped.
• Reaching a limit mid-reply. If you reach your session or weekly limit while Quant is answering, it finishes the reply within a small margin, and that counts toward your week. Your next message waits for the reset, or, on a paid plan, goes on to extra usage.

When you've reached a limit, a notice above the prompt says when it resets. On a paid plan, Continue with extra usage keeps you going now; on Free, Upgrade shows the plans.

Extra usage

On a paid plan, extra usage keeps Quant going past your plan usage instead of pausing until the reset. It's a prepaid dollar balance, bought in one click and managed on the Usage page (app.luxalgo.com/account/usage).

You can also add any amount from $10 to $2,000.

• On by default. Extra usage is on unless you turn it off. Plan usage is always used first.
• Monthly limit. Optionally set a monthly limit on what extra usage can spend.
• Auto-reload. Off unless you turn it on. When your balance falls below the amount you choose, it adds more from your saved card, and it never goes past your monthly limit.
• No expiry. Your extra usage balance doesn't expire.

Extra usage isn't covered by the money-back guarantee; see Refunds.

Credits you bought before

Credit packs you bought became extra usage at the price you paid. A partly used pack carried over its unused share.

Referrals

Referrals on the Referrals page (app.luxalgo.com/account/referrals) work as "Give $20, get $20". When a friend you referred upgrades, you each get $20 of extra usage, or $50 each when they choose a yearly plan. Your friend's arrives with their first payment; yours arrives after the 30-day refund window.

Referral rewards expire 12 months after you earn them, and they work on Free too: once Free plan usage runs out, Quant can keep going on your referral rewards.
