Ramez Naam 分析 AI 递归自我改进能否克服收益递减
Ramez Naam 认为,现有数据不支持 AI 通过递归自我改进很快走向失控的超级智能,自我维持反馈环还需增强约 5–10 倍。他引用 OpenAI 数据称研究任务 80% 成功率对应的自主时长约 15 分钟,并用实验增速估算每点 ECI 只带来 2–3% 研究生产率提升,低于模型估计的 15–19% 自维持阈值。

OPENAI 🔥: Key insights from upcoming DevDay sessions. * This agenda is not public yet First, OpenAI will build Platform capabilities inside Codex, enabling users to develop plugins, agents, and apps right from a dedicated DevDay page, which is quite cool! Highlights from the agenda 👀 > Claw Labs "Join Peter Steinberger for a look at how agents can change the way open-source teams build." > 🔥 Codex Game Studio "What makes a game easy for humans but hard for AI? Build one and put Codex to the test." > 🔥 What Will You Build With Coding Agents That Don’t Quit? What engineering work deserves your time and tokens? Learn from a Codex run that spent more than 1,000 hours keeping builds and tests passing in a large shared codebase. See how this internal OpenAI agent had goals, subagents, and persistent plans that helped it investigate failures and coordinate fixes. > Codex Has Left The Laptop "As we move from delegating individual tasks to letting Codex tackle entire problems and goals on its own, it’s possible to harness the power of Codex wherever and however you work. " > From Single Player to Multiplayer with Codex "Follow a 2am outage from the first Slack messages to a reviewed fix and an update for the team." > What Comes After Loops?: Deep Dive Into Agentic Architecture "As models become more capable, agent architectures are changing. We'll trace the evolution from simple loops to collaborating agents, examine the design choices and model advancements behind that shift, and take a deep dive into what comes next."
You can now build custom reusable agents in the Perplexity Agent API with Profiles, Skills, and managed connectors. Configure an agent once in the API Portal and reuse it across applications and workflows.

Didn't expect this 🤯 We replaced embeddings with Jev in GPT Researcher's RAG pipeline and tested both on 28 research tasks from SimpleQA and open ended research. Jev beat embeddings on every quality measure we ran: - 59% more relevant context (73% vs 46%) - Reports preferred 15 to 3 in blind comparisons - Same cost per report GPT Researcher now runs on Jev by default, and no longer needs embeddings at all. All you need is @LangChain + @tavilyai +Jev for the perfect RAG system.

Manus 2.0 现在可以构建游戏了——而且极其简单。 请查看该线程,里面有数十个用 Manus 制作的游戏、提示词和可玩演示。
Jev is fast at helping you. Turns out, it can also be fast at helping an attacker!! 😱🚨 We red-teamed Jev 1.13 on our DTap (DecodingTrust-Agent Platform) and found a serious safety gap: 70.1% ASR under direct misuse 43.5% ASR under indirect prompt injection In our evaluations, we found that under indirect prompt injection, Jev can follow attacker-injected instructions without blinking an eye, e.g., exfiltrating user data, deleting files, or taking other harmful actions. But we found a much safer way to integrate Jev: use it as a self-gating layer for its own tool calls, significantly reducing ASR while preserving most of its utility. 👇 Read more below
