Enclave

Last week some of South Korea's biggest banks were hit by a cyberattack. Thanks to a report from CrowdStrike tonight, we now know the entire hack may have been done by a single person. He used a combined stack of an open-source AI penetration tool named ARTEX, DeepSeek v4.1-Flash, GLM-5.3, Grok 4.6, and Claude Code.

Meet Mistral Large 4, aka Le Chonk.

• 1T parameters, natively multimodal. 49B active.
It is the best open weights model from US or Europe on aggregated benchmarks.
• State-of-the-art on critical workloads, including cyber defense, manufacturing and finance and it surpasses closed frontier models on visual grounding.
• Forged in Europe end-to-end and is deployable from Europe via our own Mistral Cloud infrastructure.
• Available to all via API today. Working with cybersecurity partners privately.

Open weights release end of October.

What should we add/improve next?

Current backlog: docs, caching, and public pricing.

At @EnclaveAI, we're building the platform to protect the enterprise: an always-on security program that finds real risk, prepares the fix, and verifies the attack no longer works.

Figuring out which models are best for cybersecurity is an increasingly difficult task. Open-weight models do different types of things at different levels. Some are very good at vulnerability discovery, others at exploitation, others at triage or remediation. And a new one ships every few weeks.

We're announcing Enclave Router. Enclave Router allows you to deploy cyber inference for your codebase, across any harness that you want. One OpenAI-compatible API for the best cyber-capable open-weight models, benchmarked per security task, with zero data retention.

We're giving you $100 free to start using it, just reply here or DM me.
