The same 0.35 multiplier applies to all three rates.

Night rates: 22:00-08:00 (UTC+8).
The 65% discount also applies after daily half-price rates: Uncached input $0.0525; Output $0.21; Cached input $0.00105 per million tokens.

$20.00 of standard-price usage.

Pay $7.00 for that usage at the offer rates. One allowance per eligible user, shared across all three token types.

Cache savings belong
in the whole bill.

A cache hit is charged at the discounted cache-read rate. Those tokens are not also charged as uncached input.

Your charge combines uncached input, cached input and output. Actual cache hits depend on the requests and provider; the offer does not guarantee a hit rate.

Usage allowance
$20.00 in cumulative usage at the applicable day or night standard rate, before the campaign discount. Uncached input, output and cached input share this allowance. This is a discount allowance, not free account balance.
Eligibility
Automatically available in the earliest active personal workspace of each eligible user. Team and enterprise workspaces and accounts with existing account-specific pricing are excluded.
After the allowance
After the allowance is exhausted or the campaign ends, ordinary applicable pricing resumes, including daily off-peak rates. Allowances are checked periodically; small processing overruns remain discounted.
Other discounts
The 65% campaign discount stacks with daily off-peak half-price rates from 22:00 to 08:00 (UTC+8), including cached input.
