openai
OpenAI is the developer of the GPT series and the o-series reasoning models, offering multimodal capabilities including ChatGPT, Sora, DALL·E, and Whisper. Its API supports both the Chat Completions and Responses interfaces, making it one of the most widely used LLM APIs in the world.
GPT-5.x series (flagship / recommended / ultra-fast and economical tiers); o-series reasoning models; DALL·E image generation; Sora video generation; Whisper speech recognition; TTS speech synthesis; text-embedding-3 vectorization; Function Calling; Structured Output; Assistants API; Batch API at half price; cached_input automatic caching at half price.
Conversation and customer support; code generation; image generation (DALL·E); video generation (Sora); speech transcription and synthesis; vector-based retrieval; agent workflows; structured data extraction; enterprise knowledge bases.
Image generation is billed per image (not by token); video generation is billed per second; no native long-context cache writes (no cache_write concept); high concurrency requires a quota increase request; data residency requires the enterprise edition.
