💡 Our Take
Choose DeepSeek if you are a developer or cost-conscious startup wanting o1-class reasoning at roughly 5% of ChatGPT's API price, or if you need to self-host open weights. Choose ChatGPT if you want the largest ecosystem, GPTs store, image/voice/video modalities, and an enterprise offering with Western data residency that non-technical teams can adopt without engineering effort.
