• 2026-10-17 (ai window, single-source): Sarvam AI announced Bulbul V4 Flash on October 13, 2026 — a real-time text-to-speech model covering 11 Indian languages. Covered only by Analytics Insight (https://www.analyticsinsight.net/artificial-intelligence/sarvam-ai-bulbul-v4-flash-real-time-voice-model-for-indian-languages), four days after the stated launch date; no independent verification, no pricing, and no shipped-evidence in the window. Debut threads: nothing on Sarvam exists in the storyline memory; the nearest neighbors are the frontier voice stacks (Grok Voice 3.0, GPT-Live-1/1.1, Google TTS), which this does not extend — it is a regional Indian-languages entrant at the application layer. Watch: independent confirmation of the launch, whether it reaches production deployments in Indian consumer/government stacks, and any pricing published.
