Overview

Gemini 3.5 Pro is Google DeepMind's newest flagship, unveiled at Google I/O 2026 and reaching general availability in July 2026 with the largest production context window (2M tokens) and a gated 'Deep Think' extended-reasoning mode. It is positioned as the multimodal and ultra-long-context leader. As a brand-new release it is effectively pre-benchmark — Google had not published official evals or final pricing at launch — so the figures here are provisional, and its real-world long-horizon agentic-coding reliability (historically Gemini's weak spot versus the Claude/GPT frontier) remains to be proven independently.

Strengths

  • Largest production context window (2M tokens)
  • Deep Think extended-reasoning mode
  • Natively multimodal (image/audio/video/PDF)
  • Frontier knowledge, math, and vision pedigree

Trade-offs

  • Pricing and benchmarks unconfirmed at launch (provisional)
  • Deep Think gated to top/enterprise tiers
  • Gemini agentic-coding reliability historically below Claude/GPT
  • Limited-preview rollout at GA

Fit

Best for

  • Ultra-long-context document and codebase analysis
  • Multimodal reasoning over image, audio, and video
  • Deep research and math/science

Not ideal for

  • Unsupervised long-horizon coding agents (unproven)
  • Cost-sensitive high-volume workloads

Capabilities

Ten axes, normalized 0–100 and scored the same way across the whole catalog — so a 78 here means what a 78 means anywhere else on the bench.
