What Users Say
SIMA 2
With a 1M token context window, we use Gemini to collate data across companies with huge article libraries to detect trends and power predictive sales analytics to power Claude Opus.
Gemini 1.5 Pro offers long context, smart code gen, and seamless GCP integration—ideal for QA.
The only model that supports video input today, up to 50 minutes, so the only multi-modal model that enables this on the planet. Not even openAI or Anthropic supports this yet.
