Google's multimodal LLM with very long context

Quick answer

Pick DeepSeek when the bill is the constraint: near-frontier reasoning and code at roughly $0.30 in and $0.50 out per million tokens, which is the reason it is the default cheap model in cost-sensitive automations. Pick Gemini when the input is the constraint: 2M+ tokens of context and real multimodal handling of video and PDFs. They are cheap-per-token versus big-per-prompt, not better versus worse.

DeepSeek and Gemini are alternatives in the LLMs category. DeepSeek: Frontier-grade reasoning at 1/10th the cost. Gemini: Google's multimodal LLM with very long context. DeepSeek is free; Gemini starts at $19.99/mo.

When to pick which
DeepSeek
Pick DeepSeek when
  • You are running high-volume automations where API cost per million tokens decides the architecture.
  • You want reasoning and code quality close to the frontier labs without their rates.
  • You want a free chat tier for everyday use and a very cheap API for everything scripted.
  • The work is text in, text out, and you do not need multimodal input.
Pick Gemini when
  • You need to feed in a whole codebase, a video, or a stack of PDFs in a single prompt.
  • Context length is the actual limit you keep hitting, since Gemini handles 2M+ tokens.
  • Multimodal input is core to the workflow rather than an occasional screenshot.
  • You want a flat consumer subscription at $19.99/mo Advanced instead of a metered bill.
