Gemini 2.5 Flash
Gemini 2.5 Flash is a closed, API-only model of undisclosed size. No weights exist to download, so this page covers what it does, how to reach it, and what to run locally instead.
Why you can't run Gemini 2.5 Flash locally
The vendor has not published a parameter count, which means no honest VRAM figure exists — every sizing page that quotes one is guessing. No weights have been released at all (official source linked below), so self-hosting is not a question of hardware budget.
What works instead: the hosted API. For most workloads, the open models below deliver the same job on hardware that fits under a desk.
Cloud/API only Gemini 2.5 Flash optimized for speed and efficiency. Parameter count undisclosed (cloud API).

What is the best local alternative to Gemini 2.5 Flash?
Qwen3 235B A22B is the strongest local model we track (235B, from 192 GB machines), with Qwen3.5 122B-A10B Instruct close behind. Both run on a single high-memory Mac or GPU — see their pages for exact hardware.
