Strengths	+ Excellent tool-use and structured-output reliability + Long context supports large codebases / document sets + Best-in-class for agentic coding workflows	+ Only stable GA model in the Gemini 3.x family as of June 2026; positioned for agentic execution and sub-agent deployment + 1M-token context window with thought preservation across multi-turn agent loops + Rich built-in tool ecosystem (search/maps grounding, code execution, file search, function calling)
Tradeoffs	− More expensive than Haiku for high-volume classification − API-only (no on-prem / open weights)	− Per Google docs: Computer Use is not supported at this moment (it was available in the Gemini 3 Flash Preview) − Output capped at 65k tokens, lower than competing flagships' 128k
