Building safe AGI that benefits all of humanity
AI research lab providing GPT models, image generation, embeddings, and an Assistants API.
The API is the most reliable and fastest in production of any frontier model provider — consistent latency under load
GPT-4o is genuinely capable across a huge range of tasks including code, analysis, and vision without requiring model-specific prompting tricks
The ecosystem of libraries, tutorials, and third-party integrations built around OpenAI's API is unmatched — every framework has an OpenAI adapter
Function calling and structured outputs make it practical to integrate LLM responses into typed TypeScript applications reliably
The Assistants API with file search and code interpreter handles complex RAG use cases without building your own vector database setup
Pricing for GPT-4 class models is high enough that a popular app with heavy AI usage can burn through thousands of dollars quickly
Vendor dependency on a single company for a critical product feature is risky — rate limits and outages have impacted production apps
Context window costs mean long conversations or large document analysis gets expensive fast compared to alternatives like Gemini Flash
The Assistants API is complex and has inconsistent behavior — many teams end up building their own simpler orchestration layer on top of the Chat API
