ChatGPT or DeepSeek: which should you choose?
| Dimension | ChatGPT | DeepSeek |
|---|---|---|
| Pricing | Free tier; paid plans for GPT-5.6 Sol, Luna, Sol Pro | Free unlimited chat; pay-as-you-go API with peak/valley pricing |
| Best for | All-in-one assistant: writing, coding, research, image gen, voice/video | Cost-efficient reasoning and agent workflows for developers |
| Key model | GPT-5.5 Instant (free), GPT-5.6 Sol/Luna/Sol Pro (paid) | DeepSeek-V4-Flash (public beta on API) |
| Integrations | Apple Health, MyFitnessPal, Square | None listed |

| Not for | High-security environments (AgentForger vuln, data exfiltration risk) | Teams needing turnkey collaboration or broad language support |
Pick ChatGPT if you want a polished, multimodal assistant that handles everything from image generation to deep research, and you're okay paying for the best models. Pick DeepSeek if you're a developer or cost-conscious team that needs strong reasoning and agent capability at rock-bottom prices—especially if you can tolerate a beta API and handle your own integration. For pure chat on a budget, DeepSeek's free unlimited tier is hard to beat.
