Google Gemini 3.5 Transcribe Opens API: 2.6% Word Error Rate Ranks Fifth, Real-Time Streaming Has Three Hard Limits
Google officially released Gemini 3.5 Transcribe via the Gemini API on August 26, 2026, achieving a 2.6% word error rate (ranked fifth) in non-streaming benchmarks and 4.0% in real-time streaming. The release splits into batch and streaming endpoints with three hard constraints, while Google's broader strategy extends from API access to embedding voice input directly into Chrome.
