Compare OpenAI API and Fireworks AI on deployment, pricing, model support, and more.
OpenAI API
- Tagline
- GPT-5.6, embeddings, image, and speech APIs — the default LLM API for most AI apps
- Description
- Programmatic access to OpenAI models: GPT-5.6 (Sol / Terra / Luna), legacy GPT-4o IDs where still offered, image and speech models, embeddings, and agent/assistant APIs. OpenAI-compatible Chat Completions remain the industry default interface. Confirm current model IDs and pricing on platform.openai.com — GPT-4 branding is outdated for new builds.
