Best AI APIs in 2026: speed and price compared

An AI API acts as an intermediary between applications and hosted model runtimes, facilitating tasks like provider-side inference and managing operational metadata without requiring teams to handle infrastructure like GPUs or deployment scaling. Notable providers such as Groq, Cerebras, Fireworks AI, Together AI, and Baseten offer diverse features tailored to different needs, including low-latency performance, high token throughput, broad model catalogs, and deployment control. Each provider charges primarily per token with varying price points depending on factors like model size and request type, and they offer different options for fine-tuning and dedicated infrastructure. These APIs are suitable for a range of applications, from real-time chat and voice agents to high-volume generation and custom model deployments, with the Braintrust Gateway offering a unified way to log and compare provider performance. Pricing, speed, and suitability for specific use cases depend on factors such as the model, region, and traffic volume, and users are encouraged to test providers with their own workloads to make informed decisions.
