Mistral AI launched the Mistral 3 series on December 2, 2025 — a blockbuster family of 10 fully open-weight multimodal models under the permissive Apache 2.0 license, spanning Ministral 3 (3B/8B/14B dense variants in base, instruct, and reasoning flavors) to the beastly Mistral Large 3 (675B total params MoE with 41B active). Optimized for everything from drones to datacenters, these models nail image understanding, non-English prowess, and SOTA efficiency, debuting at #2 on LMSYS Arena OSS non-reasoning while slashing token output by 10x in real-world chats. This full-line return to unrestricted commercial openness is a direct gut punch to closed ecosystems like OpenAI and Google.

At AWS re:Invent 2025, Amazon Web Services dropped the Nova 2 series — four frontier models (Lite, Pro, Sonic, Omni) engineered for reasoning, multimodal mastery, and speech-to-speech sorcery, all blazing trails in price-performance while matching or exceeding GPT-5, Claude Sonnet 4.5, and Gemini 3.0 Pro. Coupled with Nova Forge for custom model forging and Nova Act for 90% reliable browser agents, this salvo expands to 10 seismic shifts: from Trainium3 UltraServers to S3 Vectors scaling to 2B vectors. Enterprises are already slashing AI costs by 40% and accelerating deployments, signaling AWS's all-in bet on open, scalable agentic AI ecosystems.
