OpenAI Platform for humans

The OpenAI Platform is the developer product: models, embeddings, speech, images, batch, fine-tuning, and the dashboard that holds keys. ChatGPT is the consumer twin; this is the machine twin. Docs, playground, and SDKs are why almost every demo starts here. We keep it as its own entity so agent buyers are not sent to the chat app's marketing site. Twin Score on this directory is 74 for humans and 95 for agents, using the public rubric (interface, onboarding, human docs, collaboration, support, pricing fairness, accessibility, reliability versus API quality, MCP or tool surface, CLI, structured docs, machine auth, quotas, determinism, and skill packaging). OpenAI Platform is sold by OpenAI, founded 2020, headquartered in San Francisco, USA. Pricing in public materials: Usage-based tokens, tools, storage, and fine-tuning. Separate from ChatGPT subscriptions. Machine capabilities we record: API excellent, MCP basic, CLI basic, docs excellent, auth API keys, org roles, service accounts.
