- Azure OpenAI in Foundry Models, good for Teams on Azure that need OpenAI models with Entra ID, private networking, EU or US data zones or FedRAMP scope, and one resource that also serves DeepSeek, Llama, Mistral and Grok models. Ahead on Reliability, 80 against 40; Schema & documentation, 87 against 60; Agent ergonomics, 98 against 72; Security & auth, 95 against 64; Maintenance & community, 86 against 46; Transparency & trust, 83 against 53. Also Agent-ready, a grade of BB or better.
- 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.
