An API provider is a company that serves AI models over an API — either its own proprietary models or open-weights models it hosts for customers.
The market has two broad camps. Model creators such as OpenAI, Anthropic, and Google serve their own proprietary models directly. Alongside them, cloud platforms resell those models with enterprise billing, and specialist hosts serve open-weights models, competing on price and speed for identical weights.
The same open model can differ several-fold in price across providers, and quality is not guaranteed to be identical either, since hosts choose their own hardware, quantization, and serving configurations.
Choosing a provider involves more than the per-token rate: latency and throughput, rate limits, uptime record, data retention and training policies, regional availability, and compliance certifications all weigh into the decision, particularly for production and enterprise workloads.
