What Article 50 covers (plain map)

Art. 50(1) — Inform natural persons they are interacting with an AI system (chatbots, agents, voice UIs), unless obvious or excepted.
Art. 50(2) — Machine-readable marking of certain generated / manipulated content (provider technical duty; SaaS still tracks what is in scope).
Art. 50(3) — Emotion recognition / biometric categorisation notice where deployers use such systems.
Art. 50(4) — Deepfake and certain public-interest text disclosure by deployers.

Provider vs deployer matters. OpenAI may be GPAI provider; if you place the chatbot on the market, you may still own interaction disclosure and evidence. See OpenAI-powered SaaS.
