Independent LLM API price desk: compare AI model pricing across providers.
Peplio's take
AI pricing changes constantly, and most comparison pages are outdated the week they’re published or quietly copied from other aggregators. AI // COST takes the opposite approach: every number comes straight from the vendor’s own page, carries a verification date, and any correction is logged publicly. That level of transparency is rare and makes the data genuinely trustworthy.
The calculators are the most practical part. Knowing a model costs a few dollars per million tokens doesn’t tell you what your app or agent will actually cost each month. Turning rates into a real bill, including caching and batch discounts, helps developers and businesses avoid nasty surprises. The live price tape is also great for anyone who needs to react quickly to price drops or new releases.
The trade-off is that it’s a data site for people already using AI APIs, so casual users may find the token pricing a bit technical. Some links are affiliate links, which the site openly discloses. Best for developers, startups, AI product builders and anyone comparing the real cost of AI models.
