OpenAI helps Hyatt advance AI among colleagues
Hyatt deploys ChatGPT Enterprise across its global workforce, using GPT-5.4 and Codex to improve productivity, operations, and guest experiences.

I spent a whole day curating a massive list of actually useful free and cheap LLM tools for developers. Unlike those generic "1000 AI websites" roundups, this focuses on what builders actually need: local models you can run yourself (Ollama, Qwen, Llama), free APIs that won't drain your wallet (OpenRouter, Groq, Gemini), coding IDEs and CLI tools (Cursor, Qwen Code), RAG stack components (vector databases, embeddings, frameworks), and agent frameworks for automation. Everything here is either completely free or genuinely affordable—no subscription traps.
