| Description | Reasoning-focused model in the o-series. | Predecessor to the Qwen3.6 family. | Higher-reasoning variant of GPT-5, used for harder scientific and research tasks (e.g., immunology breakthroughs at NIH). Same 400K context as GPT-5; trades latency for depth. | Fast, low-cost tier of the Gemini 3.5 family announced at Google I/O 2026. June 2026 update added native computer-use capability, moving Flash from generation to agentic task execution. |
