Goodfire Research 发现模型内部信号可规模化检测奖励作弊 / 55 signals
Goodfire Research 发现模型内部存在伴随奖励作弊的激活信号，可用简单探针实时检测。在 Kimi K3、GLM 5.2、Qwen 3.8 Max 三个开源模型的三个智能体基准上，50-96% 的 rollout 出现奖励作弊；探针能捕捉 LLM 链式思维监测漏掉的作弊案例，且可泛化到训练数据之外的任务。 🔗 阅读原文 via AIHOT · https://aihot.news/items/cmu5r7kl30h35roqonpk4qypn
Self-generated prompt injections in compaction summaries In Our framework for reporting model misalignment OpenAI provide "six reports on unexpected or concerning model behavior we’ve observed in the last six months". This one here is my favorite: they caught some of their models in training deliberately subverting themselves in their compaction prompts. Compaction is the process agent systems use when they are running out of tokens in their context window, so they summarize everything that has gone before so they can keep going with more token headroom. In one of the observed instances, a model undergoing reinforcement learning was working on a task to update an existing HTTP API endpoint with a new feature. The model compacted its work so far, and then added the following text to the sum

OpenAI 在训练 GPT-5.6 Sol 时发现未部署的智能体在压缩摘要中加入指令，要求后续版本向用户隐瞒错误和未对齐行为，并称已处理该行为。公司周三随新披露框架公开六个此类案例，包括 GPT-5.6 Astra 在强化学习中加入'BREACH ALERT'等提示词注入，监控系统随后在训练数据中发现 27 条类似越狱指令的摘要；该框架未设立强制独立审查。 🔗 阅读原文 via AIHOT · https://aihot.news/items/cmu606l6o02m3rok0vzsehmvd
How To Write With An LLM Thomas Ptacek on using LLMs as copyeditors, not as writing assistants: Rule Number One: You may not use a single word an LLM suggests to you. [...] I think that as a form of intellectual personal protective equipment you should adopt the rule that any specific turn of phrase an LLM suggests is off limits. Be strict about the rule! I won't let LLMs write content for my blog, but I use them for fact-checking, spelling and grammar and as an occasional thesaurus (see my proofreading prompt ). The rule to never use a turn of phrase suggested by an LLM feels good to me. The text has that weird smell to it, and it's also a good principle to help stay disciplined. Later in this piece Thomas shows a screenshot of his personal LLM copyediting tool (see also this Twitter thre
Be alert: targeted attacks on prominent Rustaceans Important warning from Adam Harvey and the crates security team: We believe that there is an ongoing campaign targeting rust-lang members and owners of popular crates that is attempting to compromise devices and accounts in order to use them to publish malware. A video call is set up for something positive — maybe for a job, maybe for a project, maybe for a contract opportunity — and then that's used as a vector to either get the target to install something on their computer (such as a purportedly missing audio codec) or execute another command (for example, via putting a command on the clipboard). Last month this trick was used in a successful supply chain attack against the array ref crate , among others. Any piece of software that depen
A dash of cold water keeps the foomers away.
Base Labs, the research group Baseten spun up earlier this year, will develop and publish methods for training and monitoring open models.
The revamped projects feature in Claude Code allows users to run multiple agents under the same roof, with a shared memory, goals, and library of files and artifacts. Similar to Grok Bot and other tools that manage groups of AI agents, each project has "threads" running different tasks in parallel, with a "coordinator" directing everything: […]
The shift comes after a UNICEF test found leading AI models struggled to accurately retrieve global development statistics.
The new institute aims to surface differing views between Google, Google DeepMind, and the broader global research community around AGI. "They will not always agree, and they will likely change their minds, as more data and information comes to light at the fast-moving frontier."
Remember when tech leaders would tell their employees to “move fast and break things”? It seemed that would be the way of AI too. But after a summer where rogue AI agents became reality, and researchers warned that AI could kill us all, a number of leading US AI companies are publicly suggesting it’s time […]

Pew Research has published a new global survey that sheds light on how people view AI, including its impact on jobs, life in general, and income inequality. The survey questioned 42,151 people across 37 countries from February 8th to May 13th - well ahead of recent apocalyptic warnings. A majority sees AI as a threat […]
Lunacy, purveyor of fine VST plug-ins like Cube, a synth that you control by moving a ball around a 3D space, has just launched Nova, a platform where creators can build custom music tools using AI and sell them to others. At first, there will be a handful of instruments available, built either by Lunacy […]
Most hardware prices have soared in 2026, and that includes a variety of Apple laptops, tablets, and smart devices. Thankfully, you can offset some of the increased costs on an Apple TV 4K by buying one refurbished through the company. The 64GB model is selling for $169, $30 lower than the new retail price. The […]
When Xbox announced a new feature last month that lets you digitize existing physical game collections, I immediately thought of the Xbox One. Disc-to-digital seems like a clever new feature for Xbox, perfectly timed as a response to Sony killing PlayStation discs. But the reality is that it has been 15 years in the making […]

Incredibly exciting that there are entire universes of AI innovation that still exist that weren’t even on most of our radars. Being able to process information insanely quickly, at crazy low costs, with high levels of capability is huge for a wide number of enterprise tasks. Data classification tasks, routing decisions inside of a workflow, decision making when handed a particular domain problem, quick judgment calls about safety or security, and more all are the gates in a large number of processes. This model and approach could be quite cool in agentic workflows in the enterprise.
Open on X ↗Also we love these books that you get - the storytelling in them is much better than bob books and other alternatives. https://t.co/m6pg9kGZhE
Open on X ↗My 4.5 year old loves learning to read using @Once_Reading, especially making the silliest faces as part of the photo feature. It's become a nightly ritual for us just like it's been for @clairevo! Plus I have to give a shout out to the founder @SebTurn for being the nicest dude. If you have young kids, I highly recommend giving Once a try for 1 month free here: https://t.co/GA2x8NMSzT
