💡 Our Take
Choose DeepSeek if you need a free reasoning model, open weights for self-hosting, or API access at roughly 1/30th the price of OpenAI's equivalent tier. Choose ChatGPT if you need the broadest plugin ecosystem, image generation, voice mode, enterprise compliance with U.S./EU data residency, and proven reliability under load.
