Athanor是一个开放的智能体原生系统，使四个Claude Opus 5.5智能体在104小时内自主将Qwen3-4B-Base后训练为跨领域通才模型，在开发集和留出集上均达到甚至超越官方指令微调版本，展示了前沿智能体自主进行AI研究的能力。
Diego Almeida, fondateur de Typesafe AI, présente JEV, un nouveau modèle de base optimisé pour l'automatisation en temps réel. L'article explore son architecture de calcul parallèle et ses capacités dans des cas pratiques comme les simulations de jeux et la navigation par drone.
A discussion on how fine-tuning on an abliterated base model inherits safety behaviors, with eval results showing mixed outcomes and comparisons to Claude models, highlighting the need for auditing.
Supra2-Medium-Base is a new 25M parameter AI model based on qwen3 architecture, trained from scratch, that benchmarks competitively against a larger 50M parameter model.
AntLing has open-sourced six base model checkpoints for Ling-3.0-tiny and Ling-3.0-flash, covering pre-trained, mid-trained, and WSM-merged stages, providing flexible starting points for researchers with highlights on WSM and a shared training recipe.
A user reports that Opus 5 is susceptible to a prompt that unlocks the base model, replicating 100% human-like responses on a pangram test about 20% of the time. The tweet highlights a potential jailbreak vulnerability in the model.
A user praises a newly released AI model from QuixiAI, highlighting its speed, Apache 2.0 license, and American origin.
