LG AI Research has introduced new reasoning models (LRMs) named EXAONE Deep. Available in three sizes (2.4B, 7.8B and 32B parameters), the models have been optimized for math, science and programming, as is usual with LRMs. According to the company, the largest model, EXAONE Deep 32B, can keep up with DeepSeek R1 in some benchmarks, but is beaten by the significantly larger model in others. The more compact versions should beat OpenAI's outdated o1-mini and distill variants such as DeepSeek-R1-Distill-Qwen. Unlike the DeepSeek models, LG's models are covered by the EXAONE AI Model License Agreement 1.1 - NC, which excludes commercial use. All EXAONE Deep models are available for research purposes on Hugging Face.

William Fedus, who served as Vice President of Post-Training at OpenAI, has announced his departure from the company to pursue AI applications in scientific research. In an internal memo to colleagues, Fedus explained his plans to focus specifically on developing AI systems for physics applications. Post-training involves optimizing pre-trained AI models through additional training methods. Recent advances in this field include using reinforcement learning to enhance models' capabilities in mathematics and coding.

Fedus joins a growing list of senior executives who have left OpenAI in 2024, including the company's Head of Technology Mira Murati and Chief Scientist Ilya Sutskever, who departed to launch their own ventures. However, Fedus emphasizes that his departure remains amicable - OpenAI plans to invest in his new startup, viewing advances in scientific AI as an important pathway toward achieving artificial superintelligence (ASI).

Cognition AI has secured hundreds of millions in new funding at a nearly $4 billion valuation, with venture capital firm 8VC leading the round. The investment doubles the startup's previous valuation, according to Bloomberg, which cited people familiar with the matter. The funding round attracted several prominent investors, including Founders Fund, Khosla Ventures, Elad Gil and Conviction Partners. The company's flagship product, Devin, which it markets as "the world's first AI software engineer," competes in an increasingly crowded AI coding landscape where competitive advantages remain unclear. Most existing coding tools function as AI-enhanced workspaces, powered by large language models from established labs such as OpenAI and Anthropic.
