Frequently asked questions about o1
How much does the O1 API cost?
No input rate is available.
Which channel has the cheapest O1 API?
No input rates are available to compare.
What is the O1 cache-read price?
No cache-read rate is recorded; missing prices do not imply free caching.

Is there a free O1 API?
No available recorded channel lists both input and output at zero. Missing prices, free cache reads or a free chat tier do not establish a free API; check provider terms for trial credits.
How do I calculate O1 token costs and monthly spend?
Metered API cost = input tokens / 1M × input rate + output tokens / 1M × output rate. No complete input/output quote is available for a total-cost example. This excludes caching, tools, retries and other service fees; the lowest input rate does not guarantee the lowest total bill.
