Strengths & weaknesses
Strengths
- Very high sustained token throughput — built for real-time, high-volume work
- Holds a persona and multi-turn instructions far better than earlier Lite models
- Drives a desktop and works over long inputs better than its size implies
Weaknesses
- Time to first token can feel unresponsive in chat even though it streams quickly once started
- Small-model ceiling: it executes well but won't reason its way out of an unfamiliar problem
Model card reports SWE-Bench Pro 54.2%, OSWorld-Verified 74.0%, MLE-Bench 39.2%, CharXiv 74.5% no tools / 76.5% with tools; Google published none of the site's other tracked benchmarks at launch. GPQA Diamond 83.8% and HLE 17.5% are Artificial Analysis-measured figures relayed by BenchLM — AA's own model page publishes only the composite Intelligence Index (36) — so treat both as third-party. LMArena Elo 1459 is the 'gemini-3.5-flash-lite' text-arena listing (rank 43, arena.ai). Also rolling out inside Google Search. Speed per Artificial Analysis' Gemini 3.5 Flash-Lite page (Google's API), which carries no effort label.
