How it works
Variants
Open weights ship in several sizes and precisions. One page, all the variants — pick the one that fits your GPU. VRAM figures are estimates from model size.
Using it via the API
Once AxForge deploys minicpm-o-4-5 for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (minicpm-o-4-5 below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/chat/completions \
-H "Authorization: Bearer $AXFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"minicpm-o-4-5","messages":[{"role":"user","content":"Hello"}]}'
