Strengths	+ Purpose-built second-stage reranking improves precision of any retriever + Multilingual and handles semi-structured JSON documents + Pro/Fast split lets builders trade quality against latency and throughput	+ 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	− API-only (no open weights) − Adds an extra network hop and per-query cost to the retrieval pipeline	− 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
