Google DeepMind's Gemini 1.5 Pro, released in February 2024, is built on a Mixture of Experts (MoE) architecture and introduces the largest context window of any commercially available model.
**Context Window**
The headline feature is the 1 million token context window (with a 2 million token experimental version). This allows processing of hour-long videos, entire software repositories, or thousands of documents simultaneously.
**Multimodal**
Gemini 1.5 Pro natively handles text, images, video, audio, and code. Video understanding in particular is a differentiator — it can answer detailed questions about specific moments in long videos.
**Performance**
It matches Gemini 1.0 Ultra on most benchmarks despite being more efficient. On MMLU it scores 81.9%. Coding performance is strong but slightly behind Claude 3.5 Sonnet.
**Google Ecosystem Integration**
Deep integration with Google Workspace, Search, and Cloud makes it compelling for enterprise users already in the Google ecosystem.
**Pricing**
Available via Google AI Studio and Vertex AI. Pricing starts at $3.50 per million input tokens for prompts under 128K tokens.
**Verdict**
For tasks requiring massive context — video analysis, large codebase review, or document-heavy workflows — Gemini 1.5 Pro has no real competitor.
