Anthropic added WebSocket support to its Responses API to reduce latency in agentic workflows by enabling persistent connections and caching. The optimization reduced API overhead for multi-turn agent loops, with connection-scoped caching handling repeated requests without regenerating responses. This allows agents to execute tool calls and process feedback faster without repeated network round-trips.

Microsoft, meanwhile, logged a $3.2 billion gain on its Anthropic investment while marking down OpenAI by $600 million, signaling a subtle shift in which AI bets the company trusts most. Both executives are racing toward agent-based business models they believe will unlock new revenue streams beyond advertising.
