- Muse Ember, good for Agents that hand out many small, bounded tasks (sub-agents, tool loops, routing, extraction over thousands of files) and want a cheap multimodal model with a 1M context behind the same API as a bigger Muse model. Also No incidents deducted, where Vercel AI Gateway loses 3 points for them.
- Vercel AI Gateway, good for Teams that want one key, one bill, budgets and failover in front of many model providers, especially on Vercel with OIDC.
