The AI answer we saw
For developers building custom chatbots, leading platforms with robust API access include OpenAI API (GPT-4/GPT-3.5), Anthropic Claude API, Google Vertex AI (Dialogflow CX), and Cohere. OpenAI's API is widely adopted with extensive documentation and SDKs for Python, Node.js, and more. Dialogflow CX offers strong intent management and is suited for structured conversation flows. For open-source flexibility, consider Hugging Face Inference API or Rasa. Pricing is typically usage-based (per token or per request), so evaluate expected volume against cost before committing.
