Hermes Wingtips #39: the missing provider prefix
if a model id ever answers you with a 404 error, check the id before you check your keys.
providers know their models as vendor/model, and an id that lost its prefix (nemotron-3-ultra-550b-a55b instead of nvidia/nemotron-3-ultra-550b-a55b) returns a 404, so it reads like an outage.
a fix just merged for the next release: the error now names the model and suggests the prefixed id.
until then, the habit to keep in mind: vendor/model, always, and hermes model picks it correctly for you.
