| content.faq | `[{"answer":"Cohere offers a comprehensive AI platform with multiple generative language models (Command, Aya), speech recognition, document parsing, and semantic representation capabilities. The platform supports both cloud-based API access and private deployment options (VPC, on-premises, or dedicated Model Vault) with enterprise-grade security and data control. It is indexed under NLP Apis.","source":"https://cohere.com/fr/pricing","question":"What is Cohere?","confidence":0.6},{"answer":"Cohere offers a free tier, so you can start without paying. Paid plans start at $0.30. Prices are published openly on the vendor's own pricing page. Pricing changes often, so verify at source before relying on it.","source":"https://cohere.com/fr/pricing","question":"Is Cohere free?","confidence":0.6},{"answer":"We have confirmed browser-based access to Cohere. That is the extent of what we could verify from public sources, so it may well offer desktop or mobile clients we have not indexed.","source":"https://cohere.com/fr/pricing","question":"What platforms does Cohere support?","confidence":0.6},{"answer":"Yes. Cohere can be deployed cloud / SaaS, hybrid, on-premise and self-hosted, so it does not have to run on the vendor's infrastructure.","source":"https://cohere.com/fr/pricing","question":"Can Cohere be self-hosted?","confidence":0.6},{"answer":"We have independently confirmed SOC 2 and GDPR for Cohere. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as Cohere not holding them. Always confirm compliance directly before you rely on it.","source":"https://cohere.com/de/security","question":"What security certifications does Cohere have?","confidence":0.7}]` | `[{"answer":"Provides access to linguistic corpora and text processing tools for tokenization, classification, parsing, and semantic analysis.
