Gemini 3.1 Flash TTS drops granular Audio Tags

Google’s Gemini 3.1 Flash TTS enables intuitive, natural language control over vocal delivery, pace, and mood via "Audio Tags." Achieving a top-tier Elo score of 1,211 on the Artificial Analysis leaderboard, the model brings high-fidelity, multimodal speech to 70+ languages with native SynthID watermarking for developer and enterprise use.

// ANALYSIS

Google is matching ElevenLabs' naturalness while undercutting on latency and cost through direct API integration. Audio Tags replace complex SSML with natural commands, simplifying high-quality audio production for developers. Native SynthID watermarking signals Google's commitment to safety, though detection efficacy remains a challenge. The 1,211 Elo score marks a significant leap in expressivity, moving Gemini TTS from a functional utility to a creative tool. Integrated Speaker-level Specificity and Scene Direction allow for consistent, localized brand voices across global projects.

Claude Code defaults to Opus 4.8

Claude Code v2.1.154 promotes Opus 4.8 to the default high-effort model, adds dynamic workflows that can orchestrate work across dozens to hundreds of background agents, and improves fast mode economics and speed on Opus 4.8. The release also refines cleanup flows with a lighter `/simplify` path, renames effort labels for clarity, and tightens several CLI and agent workflows for heavier terminal-based coding sessions.
