[Mistral Vibe @mistralvibe]

Mistral Medium 3.5, a new flagship model in public preview by @MistralAI that merges instruction-following, reasoning, and coding into a single 128B dense model with a 256k context window and configurable reasoning effort. It's a new default model for Mistral Vibe and Le Chat. Released as open weights, under a modified MIT license.

🆕 Today, we're releasing the public preview of Workflows, the orchestration layer for enterprise AI.

🌎 Enterprise teams have capable models. What they don't have is a way to run them reliably in production. That's the gap Workflows fills. It takes AI-powered business processes from prototype to production, with the durability, observability, and fault tolerance that production actually requires.

Leading organisations like ASML, ABANCA, CMA-CGM, France Travail, La Banque Postale, Moeve, and many others are already using Workflows to automate critical processes.

🔊Introducing Voxtral TTS: our new frontier open-weight model for natural, expressive, and ultra-fast text-to-speech

🎭Realistic, emotionally expressive speech.
🌍Supports 9 languages and accurately captures diverse dialects.
⚡Very low latency for time-to-first-audio.
🔄Easily adaptable to new voices

[Chubby♨️ @kimmonismus]

Mistral AI released Voxtral TTS, a 3-billion-parameter text-to-speech model with open weights that the company says outperformed ElevenLabs Flash v2.5 in human preference tests roughly 63% of the time on standard voices and nearly 70% on voice customization.

The model runs on about 3 GB of RAM, achieves 90-millisecond time-to-first-audio, supports nine languages, and can clone a voice from just five seconds of reference audio, including cross-lingual adaptation that preserves the speaker's accent.

Really proud to be part of the release of Voxtral Realtime in AI Studio!

[Mistral AI for Developers @MistralDevs]

Since launching Voxtral Realtime, the community response has been remarkable. Today, we share the technical report, launch the Realtime playground in Mistral Studio, and share the model in Hugging Face Transformers. 🧵

@dadoonet Les plafonds restent assez haut pour la majorité des personnes. Malheureusement, en France sauf exception la majorité gagne moins que ces plafonds ...

I was curious to see @dev_lagarde talk about frontend monitoring considering how much effort we put inside of my talk and it was so interesting 🙌🙌 I didn't work with Open Telemetry much, so it was really great to hear more about it 💡💡I think that it could be interesting to try it out! @DevoxxUK #conference #frontend #monitoring #observability

[DevBcn @dev_bcn]

👀 Frontend deserves love too!
Henry Lagarde (@dev_lagarde) joins #devbcn25 to show why observability shouldn’t stop at the backend.
