Several AI model providers, including Google and ElevenLabs, are implementing significant changes to their APIs and model offerings in November 2026. Google is deprecating older Gemini models like gemini-2.5-pro and gemini-2.5-flash, rerouting traffic to newer versions such as gemini-3.8-flash and gemini-3.5-flash-lite, with associated billing and API changes. ElevenLabs is also deprecating older GPT-5 variants and Claude Sonnet 4.5, migrating users to newer models and adjusting its Realtime API behavior. These changes can impact voice agents by altering voice characteristics, response times, and tool-calling capabilities without requiring explicit deployment by the user. AI
