Back to Blog Share this post Copy url to clipboard Copied Thinking Summary Mistral released Mistral Large 4 (Le Chonk), a 1-trillion-parameter multimodal model, now available with improved coding, cybersecurity, and reasoning efficiency. It leads open-weight benchmarks in coding and defensive security while offering three reasoning modes for cost-performance balance. Fully open-weight and European-trained, it empowers sovereign AI with customizable, self-hosted deployment options. We release the weights of Le Chonk, advancing the frontier of open models in agentic coding and cybersecurity. Earlier this month, we released Mistral Large 4 (Le Chonk), our flagship 1-trillion-parameter, natively multimodal model, in public preview. The response to the preview has exceeded our expectations, and we're grateful to our developer community, early-access customers, and partners for their support, collaboration, and feedback. Since then, we've put that feedback to work while continuing to scale..."},"evidence_pages":[],"related_signals":[{"id":"d4634a9c-8fb9-4af9-b3bf-07d04fb91d45","url":"https://onlylabs.fyi/signals/d4634a9c-8fb9-4af9-b3bf-07d04fb91d45","source_url":"https://mistral.ai/news/mistral-nvidia-ai-for-industrial-engineering/","title":"Mistral Advances AI for Engineering with NVIDIA","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"mistral","name":"Mistral AI","category":"frontier-lab"},"occurred_at":"2026-10-21T12:00:20+00:00","first_seen_at":"2026-10-21T12:00:52.680675+00:00","date_source":"rss.item_date"},{"id":"54fbee02-b47f-49ea-b715-30ec340fdedd","url":"https://onlylabs.fyi/signals/54fbee02-b47f-49ea-b715-30ec340fdedd","source_url":"https://mistral.ai/news/voxtral-3/","title":"Voxtral 3","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"mistral","name":"Mistral AI","category":"frontier-lab"},"occurred_at":"2026-10-20T12:00:22+00:00","first_seen_at":"2026-10-20T16:00:53.152146+00:00","date_source":"rss.item_date"},{"id":"414b829f-27d4-4b54-b1df-1621b2857e10","url":"https://onlylabs.fyi/signals/414b829f-27d4-4b54-b1df-1621b2857e10","source_url":"https://mistral.ai/news/timestral/","title":"Introducing Timestral","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"mistral","name":"Mistral AI","category":"frontier-lab"},"occurred_at":"2026-10-15T12:00:00+00:00","first_seen_at":"2026-10-15T16:00:51.823118+00:00","date_source":"rss.item_date"},{"id":"1ed4297e-4d49-43ab-a3ee-826f8ad8a6f5","url":"https://onlylabs.fyi/signals/1ed4297e-4d49-43ab-a3ee-826f8ad8a6f5","source_url":"https://mistral.ai/news/mistral-large-4/","title":"Introducing Mistral Large 4","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"mistral","name":"Mistral AI","category":"frontier-lab"},"occurred_at":"2026-10-06T12:00:27+00:00","first_seen_at":"2026-10-06T16:00:51.585964+00:00","date_source":"rss.item_date"},{"id":"cd2ecc3a-e189-487f-acfe-409513d98d7b","url":"https://onlylabs.fyi/signals/cd2ecc3a-e189-487f-acfe-409513d98d7b","source_url":"https://mistral.ai/news/hallo-deutschland/","title":"Hallo, Deutschland!","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"mistral","name":"Mistral AI","category":"frontier-lab"},"occurred_at":"2026-09-28T15:57:59+00:00","first_seen_at":"2026-09-28T20:00:52.839043+00:00","date_source":"rss.item_date"},{"id":"1db8635a-9b93-4490-89d1-c97a7bfffde5","url":"https://onlylabs.fyi/signals/1db8635a-9b93-4490-89d1-c97a7bfffde5","source_url":"https://mistral.ai/news/mistral-x-mozilla/","title":"Mistral and Mozilla are bringing open, private and multilingual AI to your web browser","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"mistral","name":"Mistral AI","category":"frontier-lab"},"occurred_at":"2026-09-16T12:00:00+00:00","first_seen_at":"2026-09-16T08:00:50.919627+00:00","date_source":"rss.item_date"}]}
