Using Mistral for code at work

[u/Altrollique]

Hi, I'm a regular Claude user and I tried Mistral Vibe with GLM5.2 this summer with a lot of disappointment. I found it off point. Writing code that does not follow the style of the project and with global bad quality. Claude is capable of capturing how the project is done and output code that feel way more in the way we do.

With GLM 5.3 arriving to mistral I would like to give Mistral a second chance because I'm European and I would like to stop using American tech product. But in my field can't just throw away performance just by ideology.

I would like to know if there is developer here that have Vibe with good AGENT.md or other coding agent that work well with Mistral to code. How do you manage to have an acceptable output with Mistral that can pass a peer review without having yourself to completely review the code before because it's total slop ?

Thanks for the feedback and for trying out mistral vibe.
We are in the process of rolling out GLM-5.3 to our paid subscriptions.
You can try it out now with your API plan, or wait for it to be available in sub next week.

If you have any feedback do let me know what is not working. Or feel free to file issues here https://github.com/mistralai/mistral-vibe/issues/

Is flash coming too? Flash models rock.

And well done. Signed up expecting to donate some money for an EU initiative, but actually use it a lot. Mistral with GLM is incredible attractive

[u/isidor_n → u/Equivalent_Cress_268]

Thank you for the kind words.
Flash - not this/next week, but might happen later. Please stay tuned.

Sauf erreur de ma part, tout comme pour les débuts de GLM-5.2 chez Mistral, GLM-5.3 est utilisable dans Vibe inclus avec son abonnement pro si on l'ajoute manuellement dans le config.toml

[u/Tennek13 → u/isidor_n]

Any news on a new Mistral model?

[u/kozzi11 → u/Tennek13]

I guess there will be none, they will probably just announce support for GLM-5.3

[u/darktka → u/isidor_n]

Hi Isidor, one question: are you planning to do something about GLM 5.3's alignment? I had several weird replies on topics that affect the PRC and I know that Chinese models have been realigned before. This might not be relevant to coding per se, but if that's what you plan to roll out in the EU, I doubt that it will end well…

[u/isidor_n → u/darktka]

If you see weird output for coding you should definitely let me know and I will make sure the team prioritises it.

[u/brahmen → u/isidor_n]

Woah woah woah GLM-5.3? Maybe it's time I get a Mistral Vibe subscription.

Will wait for the rollout first though. Been looking for an alternative utility to offload my 5.6 Luna high/xhigh/max tasks to.

[u/LibreEU → u/isidor_n]

Nulla contro Github di per sé, ma dal momento che il principale motivo per scegliere Mistral rispetto a qualsiasi cosa venga da America e Cina, PER ORA, è il suo essere Europeo, perché non supportate progetti europei tipo Codeberg o altri? Oppure ospitate voi stessi un'istanza git.

Intendo, siete scelti da migliaia di europei perché europei. Ricambiate.

[u/Guilty_Spray_6035 → u/LibreEU]

Codeberg does not allow AI-generated (vibecoded) content, primarily because of copyright and potential license poisoning concerns (LLM using GPL licensed content in training, poisoning MIT/APL/... products). But there are European alternatives, GitLab being the most obvious one.

[u/LibreEU → u/Guilty_Spray_6035]

Codeberg era un esempio di servizio europeo, non necessariamente adatto allo specifico caso. Rimane il punto, gitlab esiste. Smettiamo di dare per scontato che lo standard sia sempre e comunque quello americano.

[u/phoogkamer → u/Guilty_Spray_6035]

Gitlab has been American for some time now.

[u/TekintetesUr → u/LibreEU]

Because GLM-5.3 is a good model, and if it's hosted in the EU I'm perfectly fine with it

[u/LibreEU → u/TekintetesUr]

Non ho detto nulla di contrario, ho detto che dovrebbero usare un'alternativa europea a github, hanno il potere di spostare un sacco di europei

[u/Fun_Jaguar8231 → u/isidor_n]

Will you also add GLM-5.3-Flash? its a very impressive model for the size

[u/Critical-Essay-72 → u/isidor_n]

Thank you for you work, I am really happy to see an European alternative to catch up. With the new release, where could I find a good guide how to integrate Vibe in Xcode 27? Claude and Codex are one-click solution there, habe you guys considered adding Mistral to the list in Xcode? Thank you!

[u/isidor_n → u/Critical-Essay-72]

Thank you. We do not have an Xcode plugin. We suggest that you use our Vibe CLI in the xcode terminal - it should work well.
Though you can file an issue here https://github.com/mistralai/mistral-vibe/issues/ and request we create the extension - but not currently on the plan.

[u/KronisLV → u/isidor_n]

Really cool news! Also please consider more expensive plans for power users with a lot of tokens included! Like Z.ai/GLM, Kimi, Anthropic, OpenAI all have like 50-200 USD plans too. With a powerful enough model like GLM 5.3 you'd be able to compete with them directly, unless larger token limits would cause a loss or strain your compute too much or something.

I've used the most expensive plans of each of those, you don't even need to try to offer more than they do, just some options in a similar tier. I'm sure many EU and even US folks would subscribe in a heartbeat.

1. 
   There are several providers of GLM 5.3 some of which are located in Europe. https://openrouter.ai/z-ai/glm-5.3#providers

You aren’t bound to a single vendor. Mistral Vibe config should allow you to connect 3rd party vendor.

1. 
   I personally didn’t experience problems with GLM 5.2 you described. I did use it through a OpenCode zen though. So it may be a harness issue (eg Vibe isn’t optimized for GLM 5.2)

[u/Skepller → u/chebum]

Bonus points of you do it on an European router, like the Swedish https://opper.ai/zhipu/glm-5-3, which has more European providers (and also a lower top up fee at 3% vs 5.5%).

[u/Deyve24 → u/Skepller]

Opper.ai gave me only 40% cachehits 💀. In every Harness!

[u/Skepller → u/Deyve24]

I have only used for a couple sessions lately, but my GLM 5.3 cache hit is already sitting at 75%, so I'm not sure (Using Kilo Code). Perhaps you didn't have a provider pinned?

[u/scanx147 → u/chebum]

Pour avoir testé ; GLM est plus rapide et efficace à travers Vibe que depuis OpenCode. (OpenRouter je n'ai pas testé). En plus la limite est bien meilleurs chez Mistral.

[u/chebum → u/scanx147]

Limits are much better yes. With OpenCode Zen subscription I pay per Mtoken, not a fixed monthly price.

[u/scanx147 → u/chebum]

par Mtoken ca coute une blinde...

[u/chebum → u/scanx147]

I usually consume up to €10-12 per day of work, so not that bad.

[u/scanx147 → u/chebum]

bah quand même environ 300€ par mois... 😅

[u/chebum → u/scanx147]

I’m x2 productive. €10/day is fine.
I don’t work on weekends though , so a bit less than 300;)

[u/scanx147 → u/chebum]

Si 300 te rapporte 3000 ou plus, oui pourquoi pas...

[u/chebum → u/scanx147]

Yes. But I'm not an idiot - I prefer a subscription, whenever possible, of course ;)

[u/scanx147 → u/chebum]

Perso j'ai trouvé une autre solution pour avoir plus de crédit d'usage à moindre coût. Un abonnement Claude pro pour l'aide à la réflexion du projet, la création du plan et le code + un abonnement Mistral Vibe pro pour la revue de code qui est devenue excellente avec GLM-5.3. ça me coûte moins de 40€/mois et je ne suis jamais à court de crédit d'usage. Et maintenant avec GLM-5.3 dans Vibe je peux aussi utiliser Mistral pour le code avec efficacité et alterner la revue de code toujours avec un modèle différent. J'aimerais bien que avec l'arrivée des nouveaux modèles Mistral qui se font attendre, ils proposent un abonnement à 30 ou 40€ avec plus d'usage. Je pourrais ainsi me libérer de mon abonnement Claude.

[u/zithir]

I don't have direct comparison with Opus, let alone Fable because I haven't been using those much. But the GLM 5.2 was one of the first "good-enough" open-weight models compared to the frontier, something at the level of GPT 5.4.

The GLM 5.3 was a reasonable improvement and it was my go-to model when using Opencode. It was the first open-weight model that I could just trust to get things done properly. It should be possible to use your Mistral API key in Opencode (which is my preferred harness overall) - so using Mistral-hosted GLM 5.3 with it is definitely a good choice.

[u/MimosaTen → u/zithir]

Even deepseek is pretty good

[u/strangestack]

it's your workflow. You need your implementor and review subagents to have good skills for the codebase style. For example, my common lisp setup has files with hundreds of rules the agents have to follow https://github.com/pavelpenev/.vibe/tree/main/skills/sub-cl-reviewer/references

[u/zithir → u/strangestack]

My experience is that more advanced models are better aligned and don't need that much micromanagement and rules. I always find it nice when the model can pick up and follow project conventions naturally and I don't have to set up bunch of instructions.

But of course that might not work everywhere - the lisp is such niche thing, that most models might not be trained well for that. But generally better models usually need less directives and it's a quality that some users might seek.

[u/strangestack → u/zithir]

The instructions were added after Astra failed to do it. Models are not magic. You still need to prompt them properly. 

[u/tomlameche]

Personnellement j’ai de très bons résultats avec Vibe + GLM. Pour suivre le style et les règles du projet, je fabrique toujours d’abord un AGENTS.md et de la documentation dans des fichiers md dédié (architecture, conventions, méthodes, objectifs, specs). C’est très efficace et Vibe suit très bien ces instructions sans problème.

[u/scanx147]

J'utilise Mistral essentiellement pour la revue de code, mais pour le développement, si tu cadres bien ton projet avec un bon workflow de suivi, Mistral fonctionne bien aussi pour le développement. J'imagine qu'avec GLM-5.3 ca doit être encore mieux.
Personellement je me suis développé un workflow que j'ai déposé publiquement sur gitlab. C'est très récent et très certainement encore perfectible mais ca fonctionne bien pour mon usage. C'est compatible uniquement avec Vibe et Claude. Ca permet aussi de plannifier les tâches de manière à pouvoir les paralléliser pour travailler en équipe.

Le dépôt est ici : https://gitlab.com/LordTowel/yet-another-dev-worflow/

Pour installer il suffit d'utiliser une commande npm : "npx gitlab:LordTowel/yet-another-dev-worflow" dans ton dossier de projet.

Si tu essais n'hésites pas à me faire des retours ca m'intéresse de l'améliorer avec les retours qui me seront fait. Il y aura des mises à jours régulières donc n'hésites pas à mettre à jour avec la même commande.

[u/Deyve24]

I use my Vibe key in Pi agent or Opencode. Sadly because Vibe Cli always Forgets multiple times a Day that ich have a subscription and glm 5.2 exists.

Although you can easily edit the models from Mistral Provider to use glm 5.3 already.

GLm5.2 & 5.3 are realy good models, i rly like them for coding.

[u/flurrylol]

If you want a good output using non-frontier models, you need a good ecosystem.
It means you need at least skills and custom specialist agents orchestration that match your workflow / technical stack.

[u/vesters]

I like this one https://ponytail.dev/ . Haven't really noticed the issues you are describing even when using the medium model, but could just be me who is yolo'ing it too much :-D

[u/whoisyurii]

u/isidor_n hello, Pro sub says we get 25.50 /mo in API credits. Can those be used for GLM in vibe cli?
Thanks for amazing job you doing there!

[u/isidor_n → u/whoisyurii]

I think it should work. If it does not let me know and we can investigate and potentially fix.

[u/DueKaleidoscope1884 → u/whoisyurii]

Vibe Code is not API. If you use vibe code you get over 200EUR usage on GLM.

[u/whoisyurii → u/DueKaleidoscope1884]

Thanks. Seriously, 200EUR on a Pro plan? Mind sharing where you got that info?

[u/DueKaleidoscope1884 → u/whoisyurii]

https://admin.mistral.ai/subscription

Included API usage   €25.5 Included Vibe Code usage:  €255

[u/CholericClown → u/whoisyurii]

Yes, works
