Best when you are still exploring providers, freshness, cached pricing coverage, and headline token rates before narrowing the shortlist.

Use providers for ecosystem coverage, changes for fresh movement, and methodology or data sources when trust or sourcing questions block the click.

Why teams can trust this pricing

This section exists to reduce trust friction before you make a cost decision or share the numbers with someone else on the team.

Methodology Data sources

Official-first, with verified fallback

Each stored price prefers the provider's public pricing page first. If that path blocks crawlers, the site keeps a verified fallback label visible instead of pretending the number came from a live official crawl.

Timestamped stored snapshots

Every number is tied to a stored snapshot time, so freshness is visible instead of implied by the render time of the page.

Normalized pricing terms

Input, output, cached, and batch fields are translated into the same pricing language across home, list, compare, and calculator views.

Decision tools use the same pricing base

The calculator and compare flows read from the same pricing layer instead of a separate rough estimation table.

Coverage snapshot

A quick operational summary of what is live now, where deeper pricing detail already exists, and where coverage still waits on fresh snapshots.

Live model pricing 16 / 16 Models with a stored pricing snapshot right now.
Providers live now 3 / 3 Providers already feeding ranking, compare, and calculator flows.
Providers awaiting snapshots 0 Catalog exists, but fresh pricing is not stored yet.
Models with listed batch pricing 3 Counts models where a normalized batch price is currently listed, not blanket provider-wide support.

Browse by provider

Provider pages are the fastest way to inspect one ecosystem at a time, including freshness, model count, and current pricing depth.

How to read pricing

Most confusion comes from a few repeated pricing terms. Keep these definitions consistent before you interpret any ranking or calculator result.

Glossary FAQ Methodology Data sources

Input price

The cost for prompt tokens. Prompt-heavy, retrieval-heavy, or tool-heavy workloads should scan this first because it often drives baseline spend.

Output price

The cost for generated tokens. Long-form generation, summarization, and agent responses often lean on this field more heavily.

Cached pricing

A discounted input rate for reusable prompt context when the provider exposes it clearly enough to normalize.

Batch and blend

Blend is a ranking shortcut based on 75% input and 25% output. Batch counts on this site mean a provider-listed batch price could be normalized for that model, not that every provider workflow runs that way by default.

What to do first

The site supports four common first steps. Pick the one that matches the decision you need to make right now.

Step 1 for budget planning Start with the calculator

Use calculator first when you already know rough token volume and need monthly spend, cache leverage, batch savings, or budget fit.

Monthly spend Budget fit Scenario templates

Step 1 for shortlist decisions Compare the same workload

Use compare when the request shape is already known and you want a side-by-side answer without rebuilding the math in a spreadsheet.

Step 1 for fresh signals Check the changes feed

Use changes first when price motion matters more than the current static table and you need to see recent up or down events across providers.

Provider coverage

Compact provider coverage makes it easier to scan who is live, how much depth exists, and where pricing gaps still remain. Batch counts here mean listed batch pricing fields, using the same contract as the providers page.
