Cohere adds third-party open models to Model Vault

Cohere has added third-party open models to Model Vault, expanding its managed inference service beyond Cohere’s own models.

At the November 3 launch, Cohere’s standard Model Vault matrix listed DeepSeek, GLM, MiMo, Gemma, Nemotron, GPT-OSS, Phi and Tencent’s Hy3 as available. The Model Vault Encrypted column listed only Gemma, GPT-OSS and Phi among those third-party families, making the encrypted offering a narrower catalog rather than a security mode available for every standard-vault model.

The catalogs are evolving. Cohere’s current standard-vault documentation lists DeepSeek, GLM, MiMo, Nemotron, Gemma, GPT-OSS, Phi, Qwen and the Mistral AI families Ministral, Devstral and Leanstral. Cohere’s current encrypted-vault list includes Gemma, GPT-OSS, Phi, Qwen, Ministral and Devstral. Cohere says exact model and GPU availability can vary by region and change over time.

Standard Model Vault is available in the United States, European Union and Canada, while Model Vault Encrypted currently runs only in the United States; Cohere describes EU and Canadian encrypted serving as coming soon. Cohere says customers choose a region when creating a vault, every model and inference request stays in that region, and the region cannot later be changed. The company presents that setup as helping customers address residency and regulatory requirements, not as a compliance guarantee.

Cohere says a standard vault uses dedicated, logically isolated infrastructure, protects data in transit and at rest, and has zero data retention enabled by default. It says Model Vault Encrypted adds end-to-end encryption, confidential computing, hardware-backed trusted execution environments and remote attestation so prompts and responses are exposed in plaintext only inside the protected environment, not to Cohere or the cloud operator. Third-party models are served through an OpenAI-compatible Chat Completions API at the customer’s vault endpoint.
