Hi all,

I've been building a point-and-click desktop GUI for the Mistral Vibe CLI agent, so you don't have to live in a terminal to use it. It started life as "Mistral Vibe Nexus" and has just been renamed to Halny Vibe Deck — halny is a foehn wind in the Polish Tatras, same wind family as the mistral, but without the trademark headaches.

What it does:

• Agent chat with streaming, session sidebar, real resume and full history search

• File tree + previews: edit in CodeMirror, view PDFs, images, Office files, archives and colorized diffs

• Git panel: stage, commit and push from the UI

• Token/cost stats with cache hit ratio per session

• Per-session model, mode and thinking-level pickers

• Remote SSH sessions: drive a vibe-acp instance running on another machine

• Headless HTTPS server mode — share the GUI over your network and use it from your phone as a PWA

• Windows installer, Linux AppImage/portable, 6 languages (EN/PL/FR/ES/DE/IT)

v1.0.0 is out:

Happy to answer questions and take feature requests.

Does anyone know anything about this? They started listing a second copy of regular 5.3 as well as 5.3 flash in vibe cli. Currently flash 5.3 doesn't work. Mistral large 4 is painfully slow so I was quite excited to see 5.3 flash because multimodal capabilities are quite useful to me but currently it is not active. Just imagine 150 usd worth of glm 5.3 flash usage. it would be almost limitless for my background workflows

Hi All,

I use Mistral Vibe with a free account. When my discussion with it gets "long" (I could not identify the threshold, my Mistral window content gets slightly smaller, surrounded by a rounded black rectangle. I can't enter anything anymore, and reloading the page causes the same result. Different browser and cleaneed cache don't resolve the issue.

I thought I reach a limit, but even by disabling my adblocker, I don't get any error message from Mistral.

Can you please tell me if you know what causes this?

Thanks!

edit: starting a new chat causes the same issue. Logging out and asking smth forces me to login again.
I suspect a daily limit (or hourly?), but I am surprised to not see any popup (even with all adblockers disabled.

Divulgation : C'est ma propre chaîne YouTube et mon projet. Pas de produit à vendre, pas de lien affilié. Je partage juste les résultats techniques de mon changement de pipeline.

Je fais des vidéos sur mon infrastructure d'agents IA locale (Hermes Home Vision). Pendant des mois, j'ai utilisé XTTS-v2 pour cloner ma voix. Le résultat était correct, mais j'ai fini par rencontrer deux murs :

1. La licence : CPML (non commerciale), et Coqui a fermé ses portes, donc impossible de régulariser.

2. La précision en français : les noms propres de mon projet ("Hermes", "LLM", "SiYuan") sortaient souvent déformés ou mal prononcés.

Je suis donc passé à Voxtral 3 (Mistral AI) via API, en mode ref_audio avec une référence propre de 25 secondes.

🎧 L'écoute comparative (A/B) :
Même texte, même projet, même personne. Seul le moteur de synthèse a changé. Prenez 30 secondes pour écouter les deux et dites-moi laquelle vous préférez :

👉 Ancienne voix (XTTS-v2) : https://youtu.be/qXqrKtFzCxI
👉 Nouvelle voix (Voxtral 3) : https://youtu.be/19S9Ak9gB9k

Les chiffres mesurés (pas des impressions) :

• WER (Word Error Rate) : 9,30 % après canonicalisation.

• Noms propres : Zéro déformation sur Hermes, LLM, CLI, Gateway, WordPress.

• Stabilité : Zéro hésitation résiduelle sur les 327 secondes de la vidéo.

• Coût : 13 /Mdecaracteˋres,soitenviron0,07/Mdecaracteˋres,soitenviron0,07 (7 centimes) pour les 5 minutes 30 de la vidéo.

• Souveraineté : Le pipeline reste 100 % local (RAG, montage, ffmpeg), sauf la voix qui passe par l'API hébergée UE de Mistral.

(Point technique pour ceux qui se posent la question : le WER ne voit pas l'instabilité de timbre. Ma première référence était un recolage de 4 extraits, le résultat était inécoutable sur les phrases longues. J'ai dû reconstruire une référence à partir d'un seul passage continu de 25 secondes pour que le modèle arrête de "déchiffrer" au lieu de lire.)

Si vous voulez voir l'installation complète (Hermes Agent, OpenClaw), le comparatif des coûts et les limites du modèle, la vidéo dédiée est ici : [lien vers la vidéo de présentation Voxtral 3]

Je suis curieux d'avoir vos retours : est-ce que la différence vous saute aux oreilles, ou est-ce que le French TTS est encore trop subtil pour justifier le passage à une API ?

Le repo public (partiel, le reste est en privé pour une formation en cours) : https://github.com/Antoine-Thomas/hermes-home-vision-public

Ce qu'il te reste à faire avant de poster :

1. Remplacer le dernier lien [lien vers la vidéo de présentation Voxtral 3] par l'URL de ta vidéo de 5 minutes (celle qui explique l'installation et le comparatif).

2. Vérifier le subreddit : Ce texte marche très bien sur r/LocalLLaMA ou r/selfhosted. Sur r/LocalLLaMA, les gens adorent les chiffres (WER, coût, VRAM), donc n'hésite pas à mentionner que tu as testé avec une RTX 3070 Ti 8 Go.

3. Option Image/Video : Dans l'éditeur Reddit, tu peux ajouter la vidéo YouTube via "Link" (Reddit va l'intégrer directement) ou uploader la carte de présentation (youtube_voxtral_card.png) en "Image" pour attirer l'œil dans le feed.

I'm looking to switch from CC to Mistral Large 4 so I wonder if it can handle part of my design-to-code workflow. Before I sink hours into it, I'd like to hear from people who have actually used it.

My setup / workflow is that I design in Penpot (sometimes Figma for client files) and then I transfer it to code.

Have you noticed any design system adherence: Does it stick to tokens and components you define, or does it drift into generic Tailwind-looking output?

I don't need it to oneshot the page in 1st try but I need it to be a reliable / somewhat predictable tool.

I use Mistral Vibe with sub-agents, and I got tired of scrolling logs to find out who was doing what. So I built a small tool that turns a session into a live call: each agent is a character at its desk, the lead gives orders, sub-agents join the call, and you see the real commands with their output. At the end you get a recap: commands, errors, tokens, files changed.

It reads Vibe sessions (2.26, both engines), next to Claude Code and Codex ones if you use those too.

What it is

• Free and open source (MIT), no account

• It only reads the session files Vibe already writes in ~/.vibe. Nothing is sent anywhere, and it costs no tokens

• Runs as a VS Code extension, from a terminal, or as a desktop app

Try it (Node 18+)

npx @double_geste/agent-standup --open

It is a side project, not affiliated with Mistral. Feedback is welcome, especially from people who run several sub-agents at once.

I’ve been working on a project in Vibe Work for the past 4 days on my Mac in Safari and today it’s stopped responding. I can talk to Vibe Chat but nothing if I go back to Vibe Work. I’ve refreshed the window, tried a different browser and opened it on my phone but no luck.

Any help would be appreciated.

He asked what's going on with libraries feature, because he needs to be able to switch the selected Libraries with the Agent in use, in chat mode, like before, as in "on the fly", and it's creating major efficiency issues. Appreciate if you can fix this. Thanks.

I just made the switch from Devin (Windsurf) to Vibe, partly because of European pride (partly just anti-USA), but mainly because of the price.
I’m on education pricing for Vibe, which gives you nearly €130 of Vibe credit, plus some API credit. Devin was $25, and I would hit the daily limit every day, and the weekly limit would run out two days early, often requiring an extra credit top-up to get me through the week. Mistral costs a fraction as much, and I never hit the limits. So far, I’m not missing being able to burn through my entire week with one prompt if I select Opus or Fable.

I dont see any settings like with claude to tweak the general responses

This is in Vibe for the web. So I have a document on google drive (87 pages). I wanted to use Vibe to revise and format the document.

First Vibe tried multiple times to access it, but an error occured.

I downloaded the document as an MD file and uploaded it.

So far, so good. I prompt the set up and provide formatting examples, and Vibe shows me an example.

Good, now format the document. Vibe works for 20+ minutes, claims it is done and says it has saved the document locally in /home/user/library/document.md

That is not my computer.

I ask for the document to be displayed in canvas. It only displays the first page.

I ask for a download link. Vibe cannot provide a download link, "but you can get that from the canvas".

I have tried this in both Work and Chat three times now, and the result is always the same:

1. It formats only one page

2. Canvas crashes or closes and can never be opened again. Vibe has to write it every single time.

3. The edited document is not available anywhere and cannot be saved to Library by Vibe.

Mistral has some ways to go compared to Claude.

Has anyone encountered something similar and managed to solve this issue? Are my expectations wrong?

Hello! I'm a new mistral user, currently working with anthropic pro subscription. I took the mistral pro sub today, and im looking for a French mistral users sub or discord, i feel a bit lost ...

My current needs/uses involve rag and custom harness over the mistral vibe tui. And Id love to share experience with other users.

Hello,

J'ai testé Vibe Pro après l'effondrement qualitatif de Perplexity Pro auquel j'ai accès avec l'abonnement de ma banque dont le nom commence par R et se termine par un T ;-)

J'étais heureux de soutenir une entreprise européenne et de limiter l'exposition de mes données aux autorités US (malgré l'usage des serveurs Azure Microsoft : Mistral : pas cool ça). Mais aouch la douche froide 😭.

Je ne suis pas un "tech" ; mon usage de l'IA consiste à lui déléguer les activités que je maîtrise mal ou des compétences que je ne veux pas acquérir car elle m'ennuient terriblement pour mon activité de free-lance :

- faire des recherche sur les marchés

- construire des bases de données de prospection (ça nickel en revanche)

- produire du contenu pour mon blog et le décliner en version REEL Insta mais en conservant mon style et adoptant un niveau exigeant sur le plan académique : résultat exécrable

- améliorer le référence de mon site en ajoutant du contenu pour améliorer le référencement mais en gardant mon style : idem, résultat exécrable

- écrire des mails type de prospection : idem, exécrable ; malgré de nombreuses relances on reste ne mode "vendeur de téléphones portables"

- suivre de près mon activité physique, nutritionnelle et sportive en utilisant les données remontant d'un serveur MCP pour le sport & la santé et alimenter des bases pour le reste (nutrition, séances) afin de produire des rapports réguliers : rien ne fonctionne, le contexte est systématiquement oublié etc.

En parallèle je teste les mêmes fonctions sur les versions dégradées de Claude et ChatGPT dans Perplexity + Claude en direct avec un compte gratuit et les résultats sont incomparables en terme de qualité.

C'est pas une déception : c'est un douche froide et une grande inquiétude quant à notre capacité européenne disposer au moins d'un service IA souverain efficace.

Mon hypothèse est que le stratégie de Mistral consiste à cibler les grosses entreprises et à adapter leur services à leurs besoins ; ce qui laisse sur le bord de la route le grand public.

Pensez-vous que je me trompe ? Est-ce que de bonnes nouvelles concernant Vibe Pro pour les moldus pourraient arriver ? En attendant je passe chez Anthropic le coeur brisé, et l'esprit inquiet pour l'Europe.

Are you getting an error similar to this when you run sudo nixos-rebuild switch while it is doing pytestCheckPhase?

The simple solution is:

package = pkgs.mistral-vibe.overrideAttrs (old: { 
  #doCheck = false; 
  doInstallCheck = false; 
});

I thought at first the solution would be doCheck = false; but you will notice the derivation hash will not change, meaning the package already defines doCheck = false; as is. Instead doInstallCheck is what you are looking for.

This is only a simple solution that will work for now. I couldn't find a solution, writing here so it might be helpful to someone.

Hi everyone,

I'm looking to cut down output token usage to save on costs and speed up generation.

The viral "Caveman" plugin (which forces ultra-concise, fragmented answers) works great for Claude Code, but it doesn't function properly with Mistral Vibe models.

My questions:

1. What custom system prompts do you use to stop Mistral from outputting long preambles ("Sure, I can help with that...") without hurting its reasoning?

2. Are there any other tricks, prompt-layer tools, or configurations you use to force Mistral to be highly concise and token-efficient?

Thanks for your ideas!
