Anthropic adds message threads to its API, but the token bill stays the same
Anthropic has launched message threads in public beta on its API: an agent sends the full conversation once and afterwards only the new messages. According to The New Stack, the token bill does not fall.
Who is affected and how
- senior developer
- If you build your own agent on the Claude API, threads may speed up response times, but do not expect lower costs.
- startup founder
- Token costs have to be optimized another way, because threads help with latency, not with the bill.
