Estimates use tracked list rates. They are not actual charges or a billing commitment. Taxes, tool fees, negotiated rates and provider-specific limits may differ. Provider sign-in is required to buy credits.
Historical rates apply to the named model version and price schedule. They do not imply this model is still available or that an API alias still serves the same version.
This exact listing has no usable recorded price yet. Pricing sources are checked daily; a successful priced observation will establish the baseline, and later changes will extend the chart.
Input and output prices are unknown, not zero. Check collection status or read the provider documentation
Each source has its own history. We don’t join conflicting sources into a single price trend. Standard input prices exclude cache discounts.
These are the earliest and latest successful checks we can prove from our retained polling records. Reconstructing an older price never moves these timestamps backward.
A baseline of these monitoring records was preserved on . The current checks below may be newer.
A successful check of this exact listing has not been established. Stored price observations can still appear above; they do not prove continued availability. Sources are checked daily.
A reconstruction from dated sources. The effective date, publication date, and date we added the evidence are recorded separately. Coverage is incomplete; an absent event does not prove nothing changed.
Earlier launches and price changes have not been verified for this listing. The price chart above uses our recorded observations independently; daily collection does not wait for historical research.
What open-source model catalogs (LiteLLM, models.dev) recorded for this listing, dated by their commits. A range means the catalog changed somewhere between two inspected commits. These are unverified against the provider and never anchor price lines; use the reviewed events above for launch and change dates.
First listing in the inspected snapshots, not necessarily the model’s launch. Provider launch date requires review.
