Models & Research

Microsoft’s first streaming transcription model debuts atop Artificial Analysis accuracy rankings — Microsoft AI released MAI-Transcribe-2-Streaming, its first streaming speech-to-text model, which it says ranks first for both final and partial transcript accuracy on Artificial Analysis. The release also includes two text-to-speech models: MAI-Voice-2.1 and the faster, cheaper MAI-Voice-2.1-Flash. Microsoft ↗

My takeaway: Streaming transcription returns initial partial transcripts in just over 100 ms, and Flash speech generation costs $15 per million characters. This can be really a good option for those service with voice agents. Just FYI, the $0.54-per-hour transcription price is introductory through the end of 2026.

ElevenLabs unveils Eleven v4, its most emotive speech model — ElevenLabs introduced Eleven v4, a text-to-speech model it describes as its most expressive yet, designed to adapt delivery to the speaker and context. The release also includes a low-latency variant, Eleven v4 Turbo. Elevenlabs ↗

My takeaway: I listened to a few samples and was really impressed by how expressive the model sounded, especially when conveying anger or laughter. You can try it for free.

Cloudflare launches Clef, open-source models for fast AI decisions — Cloudflare introduced Clef and Clef-flash, models that classify text and images and return structured answers with probabilities for tasks such as routing support tickets, selecting tools, and detecting threats. Available on Workers AI and under an Apache 2.0 license, the models prioritize speed, with Clef-flash achieving roughly 39 ms median latency in Cloudflare’s benchmarks. The company also announced a hands-on reinforcement-learning fine-tuning service, with a self-service platform planned. Cloudflare ↗

My takeaway: Following growing interest in Jev, Cloudflare released its own decision models, Clef and Clef-flash. These open-weight models support image inputs and outperform Jev on many of Cloudflare's reported benchmarks. You can find both on Cloudflare's Hugging Face page.
