What Users Are Saying
Gemini 1.5 Pro Users
“Users are amazed by its ability to recall information from massive documents and videos. However, some find its reasoning consistency slightly behind GPT-4o in short-context tasks.”
Llama 3.1 405B Users
“ The open-source community celebrates Llama 3.1 405B as a milestone for democratizing AI. It's powerful but requires significant hardware resources to run locally.”
Final Verdict
Gemini 1.5 Pro excels in multimodal understanding and massive context. Llama 3.1 405B is the choice for text-heavy, high-intelligence tasks where open weights and privacy are non-negotiable.
