OpenAI Codex & ChatGPT 团队成员 Thibault Sottiaux 宣布 API 现支持 12 小时缓存，登录用户在 Codex 与 Work 中缓存永久有效，无回访惩罚，确保命中缓存。同时修复了约 4 万账户用量限制不一致的问题，将单独联系用户并补发额度。

Thibault Sottiaux of Codex & ChatGPT at OpenAI announced that the API now supports 12-hour caching, while logged-in users on Codex and Work keep cache forever with no penalty for returning to old conversations. Separately, about 40,000 accounts had inconsistent usage limits applied; the team is contacting them and adding credits.

Box CEO Aaron Levie 指出，AI 正从 LLM wrapper 跃升为面向特定任务或领域的自主系统。更强的工具与计算机使用能力、垂直领域模型判断力提升，以及沙箱、文件系统等 harness 基础设施，使 agent 能可靠执行复杂工作流，并已出现在 IT 自动化、网络安全、药物发现等场景。

Box CEO Aaron Levie argues we now have an emerging form factor for AI: autonomous systems dedicated to specific tasks or domains. Better tool and computer use, improving model judgment in verticals, and maturing harnesses (sandboxes, file systems) let agents tackle sophisticated work with human oversight, already appearing in IT automation, cyber ops, drug discovery and more.

OpenAI CEO Sam Altman 表示非常感激 Aleksander 接受邀请负责 superintelligence 的安全与安全挑战，这些挑战巨大，而他具备优秀的技能组合来应对。

He called Daytona one of the iconic companies of the AI era.

Builder Zara Zhang 认为，早期产品构建者拥有自己受众的最大优势并非分发，而是能测试不同想法与角度看什么能共鸣，并找到前 100 名早期用户。信号大于分发。

Builder Zara Zhang argues that for product builders in the earliest stages, the biggest advantage of having an audience is not distribution but the ability to test ideas and angles for resonance and find the first 100 early adopters. Signals beat distribution.

Vercel CEO Guillermo Rauch 宣布将驱动 Eve 与 Workflows 的耐久性基础设施扩展到所有 harness（如 Pi 和 OpenCode），支持本地、Vercel 或自建，并真正开源、运行时无关。即使 Claude Code 和 Codex 也可借此实现耐久与可观测，但它们目前不适合嵌入。

Vercel CEO Guillermo Rauch announced extending the durability infrastructure powering Eve and Workflows to all harnesses such as Pi and OpenCode—open-source, runtime-agnostic, usable locally, on Vercel or DIY. Even Claude Code and Codex can become durable and observable this way, though they are less efficient for embedding.

Peter Steinberger 分享高效工作流：用 Astra 做规划、Sol 6.1 做编码，在 worktree 中运行 Codex CLI 远优于依赖 subagent；再用第二个 agent 监督保持轨道，并为此写了 OC-plugin "smart goal"。Y Combinator CEO Garry Tan 宣布 GStack 现已 Capy 感知，完美配合其软件工厂 Captains 功能。

Peter Steinberger shared that prompting Astra to run Codex CLI in worktrees works far better than subagents, with a second agent overseeing to keep focus; he built an OC-plugin for this "smart goal" feature. Y Combinator President & CEO Garry Tan announced GStack is now Capy-aware and works great with their software factory Captains feature.

SPC 普通合伙人 Aditya Agarwal 指出，Inference time scaling → Subagents → Agent Swarms 的演进，与 CPU Threads → Multi-core CPUs → Multi-Node Distributed Systems 高度相似，历史再次押韵。

SPC General Partner Aditya Agarwal noted that the progression from inference-time scaling to subagents to agent swarms looks a lot like the path from CPU threads to multi-core CPUs to multi-node distributed systems. History rhymes.

Vercel CEO Guillermo Rauch 预测 AI 将计算你理解与不理解的精确差距，帮助渐进学习任何想法，达到个人能力上限，实现免费终极教育。Swyx 吐槽 Opus 写作出色，但只要 prompt 含随机敏感词就会出问题，无法作为 AI 媒体组织的关键路径。

Vercel CEO Guillermo Rauch predicted AI will compute the perfect delta of what you understand and don’t, enabling progressive learning of any idea until you reach your maximum capability—the ultimate free education. Swyx noted Opus is great for writing until random no-no words appear in the prompt, calling it unusable as a critical path for an AI media organization.

Peter Yang 分享与 Mercury 的合作，推出 Mercury Payroll，将工资发放整合进账户，并处理州税注册与余额检查，缓解一人 S-corp 的痛点。Every CEO Dan Shipper 深度书评 Meghan O'Gieblyn 的《Will and Attention》，探讨实用主义、欲望与戒酒故事如何塑造自我。

Peter Yang partnered with Mercury on Mercury Payroll, bringing payroll into the account with state-tax registration help and live-balance checks—addressing the pain of one-person S-corp payroll.

Y Combinator CEO Garry Tan 批评加州资产没收税是在杀死金鹅，而非享受无限金蛋。Google Labs 推出 Dreambeans Roulette 系列，邀请用户用 Dreambeans 生成并执行早晨故事。Peter Yang 预测 Fable 5.5 将在几秒到几周内到来，并令人惊叹。

Y Combinator President & CEO Garry Tan criticized California’s asset-seizure tax as eating the golden goose instead of enjoying unlimited golden eggs. Google Labs launched Dreambeans Roulette, a series inviting users to generate and act on morning stories with Dreambeans. Peter Yang predicted Fable 5.5 will arrive anytime from seconds to weeks and be breathtaking.
