What is Gemini best for?

1 million token context window far exceeds DeepSeek's 64K limit. Real-time Google Search grounding provides live, cited information. US-based infrastructure preferred for organisations with data compliance requirements

What is DeepSeek best for?

Open-source weights allow self-hosting and complete data sovereignty. API costs are 30–50x lower than comparable models — critical for high-volume use. Reasoning model (DeepSeek-R1) matches frontier performance on math and logic tasks

Gemini VS DeepSeek

Gemini (Google) and DeepSeek represent two different approaches to frontier AI. Gemini is a closed, Google-backed model deeply integrated with Search and Workspace. DeepSeek is a Chinese open-source model that offers near-frontier performance at dramatically lower API costs. The decision typically comes down to ecosystem, data residency, and budget.
