Baidu AI Research crew has simply launched ERNIE-4.5-21B-A3B-Thinking, a brand new reasoning-focused giant language mannequin designed round effectivity, long-context reasoning, and gear integration. Being a part of the ERNIE-4.5 household, this mannequin is a Mixture-of-Experts (MoE) structure with 21B whole parameters however solely 3B energetic parameters per token, making it computationally environment friendly whereas sustaining…

A workforce of researchers from MBZUAI’s Institute of Foundation Models and G42 launched K2 Think, is a 32B-parameter open reasoning system for superior AI reasoning. It pairs lengthy chain-of-thought supervised fine-tuning with reinforcement studying from verifiable rewards, agentic planning, test-time scaling, and inference optimizations (speculative decoding + wafer-scale {hardware}). The result’s frontier-level math efficiency with…
