Many models, not one.
Betting a product on a single model provider is a bet on a market that reprices every few weeks. Muse Mesh builds the layer underneath that assumption: one API across 300+ models from 50+ providers, and the app that proves it works.
Switching model is one line
The argument for a routing layer, in the only form worth making it: something you can check.
client = OpenAI(
base_url="https://mume.ai/api/v1",
api_key=…
)
client.chat.completions.create(
model="anthropic/claude-sonnet-4.6",
messages=…
)One line. The SDK, the base URL and the request shape are unchanged — that is the whole migration.
Two ways to work with us
The same routing layer, reached two ways.
What running it has taught us
Measured across our own production traffic, because the alternative is guessing about the market you are building for.
This is why a routing layer matters to us and not only to a buyer: the model that answers a question best is often not the one that answers it best in English.
Why a mesh
Three things stop being your problem the moment models are interchangeable.
No provider lock-in
Switching model is a string change, not a migration. When a cheaper or better model lands, you move that afternoon.
One bill, one key
Twenty provider accounts, twenty invoices and twenty rate limits collapse into one of each.
Per-provider transparency
Every model page publishes what each upstream provider does with a prompt — trains, retains, or keeps nothing.
Where we are
Honestly stated, because a vendor evaluation finds out anyway.
Tell us what you are building.
Volume pricing, data-handling questions, or something the API does not do yet — all of it starts the same way.
