Over the holiday weekend, key AI developments include the upcoming release of Grok 4, Perplexity teasing new projects, and community reactions to Cursor and Dia. Research highlights feature a paper on Reinforcement Learning (RL) improving generalization and reasoning across domains, contrasting with Supervised Fine-Tuning's forgetting issues. Energy-Based Transformers (EBTs) are proposed as a promising alternative to traditional transformers. AI21 Labs updated its Jamba model family with enhanced grounding and instruction following, maintaining a 256K context window. Baidu open-sourced its massive 424 billion parameter Ernie 4.5 model, while Kontext-dev became the top trending model on Hugging Face. Advances in length generalization for recurrent models and the introduction of 2-simplicial attention were noted. In biomedical AI, Biomni, powered by Claude 4 Sonnet, demonstrated superior accuracy and rare disease diagnosis capabilities. Additionally, the Python package manager
uv received praise for improving Python installation workflows. not much happened today

Meta has poached top AI talent from OpenAI, including Alexandr Wang joining as Chief AI Officer to work towards superintelligence, signaling a strong push for the next Llama model. The AI job market shows polarization with high demand and compensation for top-tier talent, while credentials like strong GitHub projects gain importance. The WizardLM team moved from Microsoft to Tencent to develop open-source models like Hunyuan-A13B, highlighting shifts in China's AI industry. Rumors suggest OpenAI will release a new open-source model in July, potentially surpassing existing ChatGPT models. Baidu open-sourced multiple variants of its ERNIE 4.5 model series, featuring advanced techniques like 2-bit quantization, MoE router orthogonalization loss, and FP8 training, with models ranging from 0.3B to 424B parameters. Gemini 2.5 Pro returned to the free tier of the Gemini API, enabling developers to explore its features.
Cursor @ $9b, OpenAI Buys Windsurf @ $3b

OpenAI is reportedly close to closing a deal with Windsurf, coinciding with Cursor's $900M funding round at a $9B valuation. Nvidia launched the Llama-Nemotron series featuring models from 8B to 253B parameters, praised for reasoning and inference efficiency. Alibaba released the Qwen3 family with MoE and dense models up to 235B parameters, ranking highly in coding and math benchmarks. DeepSeek introduced Prover-V2, an open-source AI for math reasoning with an 88.9% pass rate on MiniF2F-test. Microsoft released reasoning-focused Phi-4 models, outperforming OpenAI's o1-mini. Baidu debuted turbo versions of ERNIE 4.5 and X1 for faster, cheaper inference. Suno v4.5 added advanced AI music generation features, while Runway Gen-4 References enable placing characters into scenes with high consistency. KerasRS, a new recommender system library optimized for TPUs, was released by Fran ois Chollet.
