HN debate: Google sunsets Gemini 2.5 Pro in October, leaving enterprise users stranded

waldrews · hn · 2026-09-12

An HN poster raises alarm that Google plans to sunset the Gemini 2.5 Pro/Flash models in October before any Pro-class model reaches general availability in the 3.x generation (with geo restrictions still in place), pushing everyone to 3.x Flash.

Flash beats the older Pro models on benchmarks, but isn't equivalent for reasoning-heavy tasks like complex reasoning over very large documents. The poster highlights Gemini's unique niche in document comprehension — thousand-page inputs consuming only 300k tokens — something neither OpenAI nor Anthropic offers even at 10x the token-adjusted price. He calls it a totally unnecessary own goal by Google and is weighing whether to engineer around competitors' limits instead.
