Cohere has appointed cybersecurity leader Jaya Baloo as CISO following her role as co-founder of AI-native cybersecurity company AISLE. Baloo previously served as CISO at Rapid7, Avast, and KPN Telecom and has advised the World Economic Forum and Europol’s European Cybercrime Centre, with experience in cyber resilience, critical infrastructure, vulnerability management, and quantum readiness. AISLE developed autonomous AI systems to discover, validate, and support remediation of unknown software vulnerabilities, reporting more than 500 such findings across over 100 codebases during its first year out of stealth. At Cohere, Baloo will shape security strategy for a platform combining frontier AI models, agentic applications, secure deployment infrastructure, and cybersecurity capabilities, supporting the company’s aim to let organizations deploy governed and secure AI wherever their data resides.

Cohere announced that its Embed 5 and Rerank 5 retrieval models are available through OpenRouter, allowing developers to build retrieval-augmented generation pipelines through a single API key, client, and billing system. The walkthrough describes an offline indexing stage that embeds document chunks with Embed 5 Pro for quality, followed by an online process that embeds queries with lower-latency Embed 5 Fast, retrieves semantically similar candidates, reranks them with Rerank 5, and sends only sufficiently relevant sources to a chat model for cited answers. Embed 5 Pro and Fast share an embedding space, enabling a quality-focused index with faster query-time retrieval, while Rerank 5 provides calibrated relevance scores that support a consistent threshold for filtering weak context. The example uses an in-memory NumPy vector store and fictional API documentation, but recommends production vector databases and potential extensions including hybrid keyword-vector search, smaller vectors, support for images and PDFs through parsed text, and evaluation using labeled real-world queries.

Cohere has expanded its Model Vault platform to let enterprises run both Cohere models and selected third-party open models, including DeepSeek, Gemma, GPT-OSS, Phi, GLM, MiMo, Nemotron, and Hy3, within a managed inference environment designed for regulated and sensitive workloads. Model Vault uses isolated single-tenant infrastructure, supports regional data residency in the United States, European Union, and Canada, and applies zero retention of prompts and outputs by default. Model Vault Encrypted, currently available in the United States, adds confidential-computing protections intended to keep data encrypted during processing so that neither Cohere nor cloud providers can access prompts or outputs. Cohere describes this approach as sovereign inference, enabling organizations to control data location, access, model choice, and deployment while avoiding the operational burden of managing their own infrastructure. The company plans to add encrypted regional support in the EU and Canada, support larger confidential workloads, and broaden its model and regional availability.
