GPT-4o
GPT-4o is a model you reach through an API — too large to self-host, so this page covers what it does, how to access it, and what to run locally instead.

Frequently asked questions
Can I run GPT-4o locally?
Not realistically. GPT-4o is a vendor-undisclosed-size model; a Q4-class build would need far beyond any consumer machine. The hosted API or a smaller open model is the practical path.
How do I access GPT-4o?
Through the vendor-hosted API. See the official source linked on this page.
What is the best local alternative to GPT-4o?
Qwen3 235B A22B is the strongest local model we track (235B). It runs on a single high-memory Mac or GPU; see its page for exact hardware.
