Deep dive
The capability footprint differs most on vision: Gemini Deep Research Preview, multimodal input: Gemini Deep Research Preview, function calling: Gemini Deep Research Preview, tool use: Gemini Deep Research Preview, and structured outputs: Gemini Deep Research Preview. Both models share the core language-model surface, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
For cost, Gemini Deep Research Preview lists $2/1M input and $12/1M output tokens on the cheapest tracked provider, while DeepSeek V3 0324 lists $0.27/1M input and $1.12/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts DeepSeek V3 0324 lower by about $4.47 per million blended tokens. Availability is 1 providers versus 3, so concentration risk also matters.
Choose Gemini Deep Research Preview when long-context analysis and larger context windows are central to the workload. Choose DeepSeek V3 0324 when provider fit, lower input-token cost, and broader provider choice are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
FAQ
Which has a larger context window, Gemini Deep Research Preview or DeepSeek V3 0324?
