By default, what happens to the conversation history when a user starts a new API call to Claude?
Select an answer to reveal the explanation.
Short Explanation
Every API call to Claude starts fresh — like calling a very knowledgeable friend who has amnesia between calls. You have to remind them what you talked about last time.
Full Explanation
Claude's API is stateless by design. Each API call is independent, and Claude has no built-in mechanism to remember previous interactions. To maintain conversation continuity, developers must explicitly include prior messages in the 'messages' array of each API request. This is a key architectural pattern when building conversational applications. The claim that Claude automatically remembers all previous conversations for that user is false — there is no automatic cross-session memory. The claim that the previous conversation is stored in Claude's memory for 24 hours is false — no 24-hour retention exists. The claim that Claude stores conversation history in a built-in database accessible via a special API endpoint is false — no built-in conversation database endpoint exists in the Anthropic API.
