Use Cases
Chatbots & Virtual Assistants
Chatbots & Virtual Assistants
Build conversational AI that understands context and provides helpful responses. Our chat models support multi-turn conversations with streaming for real-time interaction.
Semantic Search
Semantic Search
Convert text into embeddings for similarity search. Find relevant documents, answers, or products based on meaning rather than keywords.
Content Moderation
Content Moderation
Automatically detect harmful content, spam, or policy violations before they reach your platform. Protect your users and brand.
RAG Applications
RAG Applications
Combine embeddings with chat completions to build retrieval-augmented generation systems that answer questions from your knowledge base.
Voice Applications
Voice Applications
Build voice-enabled applications with speech-to-text and text-to-speech capabilities in 100+ languages.
