Ask HN: Did Google kill its enterprise workhorse model?

The Gemini 2.5 Pro and Flash models will be retired in October, leaving no general-availability Pro-class model for heavy reasoning tasks. Google is urging users to switch to Gemini 3.x Flash, which outperforms the older Pro models on benchmarked tasks but does not match their capability on large-document comprehension, where Gemini handled thousand-page inputs with only 300 k tokens. This raises concerns about Google’s ability to meet enterprise needs compared with competitors.
