Chatbots and conversational assistants rely on models that hold context, match brand voice, and stay consistent over long exchanges. In 2026, the line between “consumer chat” (ChatGPT, Claude, Gemini) and “embedded chat” (API for your app or site) is blurring.
Consider: cost per conversation (input + output), rate limits (requests per minute), and customization (system prompt, memory). “Reasoning” models (o1, Claude) help with complex questions; lighter models (GPT-4o mini, Mistral) are enough for simple support or FAQ. Consumer plans (ChatGPT Plus, Claude Pro) often include a fixed quota; the API suits control and scale.
