OpenAI
OpenAI is the company behind ChatGPT and the GPT models. Through its API platform, you can build your own AI applications on top of them.
OpenAI is the company behind ChatGPT, the GPT models, and DALL-E, founded in San Francisco in 2015. This entry covers the platform: You build your own products on top of these models via the API; ChatGPT itself is merely the most well-known showcase and has its own dedicated entry.
Typical projects include: Support automation with proprietary knowledge, document analysis in the back office, and AI features in your software. Its strength lies in its ecosystem; there's hardly a library or no-code platform that doesn't integrate OpenAI first.
Anthropic, with Claude, offers a strong alternative for long texts and code, while Google entices with Gemini through pricing and context size. OpenAI remains the benchmark, but it has its quirks: models are quickly deprecated, which incurs maintenance costs for ongoing integrations, and token costs at scale warrant a close look.
Ideal for teams with developers looking to integrate AI into products and processes. If you're just looking for a work assistant, check out the ChatGPT entry; for API alternatives, Claude and Mistral are worth considering.
