Gemini
Gemini 3.1 Pro — Google
Google's multimodal workhorse. Upload literally anything — text, images, audio, video, entire PDFs — and it'll process it all in a single prompt. Nano Banana 2 (now on Gemini 3.1 Flash Image) makes it brutally effective at image generation with sharper text and better instruction following.

Overview
Gemini is Google DeepMind's flagship AI, and the 3.1 Pro release is their most capable model to date — ranking #1 on 12 of 18 benchmarks with 2x the reasoning power of its predecessor.
What truly sets Gemini apart is its native multimodal architecture. While other models bolt on vision or audio as afterthoughts, Gemini was built from the ground up to process text, images, audio (up to 8.4 hours), video (up to 1 hour), and PDFs (up to 900 pages) all in a single prompt. No preprocessing, no separate APIs, no workarounds.
The Deep Research mode is a standout: it analyzes hundreds of sources in real-time and generates comprehensive research reports in minutes — think graduate-level literature reviews on demand.
Access for free at gemini.google.com, or start with Google AI Plus at $7.99/mo for expanded access. Power users will want AI Pro ($19.99/mo) for the full Gemini 3.1 Pro experience with Deep Research. If you need the heaviest reasoning firepower, AI Ultra ($249.99/mo) unlocks Deep Think mode and cutting-edge features. Flash Live brings real-time voice dialogue to the mix.

Limitations
Long-context reliability degrades past ~120-150K tokens with rising "summary drift" and hallucinated content
Verbose outputs — generates 4x more tokens than average in evaluations, driving up costs
Structured output inconsistency — only 84% schema-valid JSON responses without retries
Strict rate limits — even Tier 1 paid users limited to 250 requests/day
Scanned PDFs need OCR preprocessing; raw uploads lead to mangled tables
High time to first token (33.59 seconds for reasoning mode)
Regional access restrictions can disrupt professional workflows
