If you're a cost-sensitive API builder who needs high-quality performance without the frills, DeepSeek is your best bet. Its open-weight models allow for self-hosting, making it an excellent choice for teams who want more control while keeping costs low. However, if strict data residency is a concern or you're looking for a highly polished consumer product, you should avoid it.
On the other hand, if you're heavily integrated into the Google ecosystem, particularly if you use Google Workspace, then Google Gemini is the ideal choice. Its multimodal capabilities and tight integration with Google services provide a powerful tool for users who can leverage its strengths. However, if you prefer open-source solutions or want to stay away from Google, Gemini would not be suitable for you.
