马斯克今天宣布收购cursor，openai发布codex新版向开发者倾斜，加上之前的anthropic focus企业用户大科技，GLM变相涨价限制普通用户倾向开发者。。。 这些种种行为说明通过代码生成能力不断提升而实现模型领先甚至agi已经成为了更广泛的市场玩家的共识 这是目前最优训练路径的选择。 相比自然语言，代码具备三个关键优势： 一是强可验证性，能否运行、是否通过测试，都提供了极高质量的反馈信号； 二是天然结构化，语法、逻辑、模块化组合，本质上是对人类思维过程的压缩表达； 三是任务复杂度高，天然包含多步推理、状态管理和调试迭代。这使得模型可以在“写代码—运行—报错—修复”的闭环中持续自我强化，这一点极其接近真正的智能系统。 因此，行业并不是在押注“写代码”这个应用本身，而是在利用代码这个环境，训练模型的推理能力、问题分解能力以及迭代能力。代码只是载体，目标是让模型具备工程师级别的解决问题能力。这也是为什么在传统 scaling law 边际递减的背景下，代码成为新的增长引擎：它提供了更密集、更可靠、更可自动化的训练信号，同时也具备清晰的商业化路径。 但代码并不是终点。它的局限同样明显：完全规则化、缺乏物理约束、偏符号系统。这意味着，仅靠代码路径，很难解决现实世界中的不确定性、噪声和复杂环境问题。 于是杨立坤的第二条路径也收获了不少市场关注：把模型放入“有反馈的现实系统”中。核心不是机器人本身，而是构建一个类似代码环境的闭环——决策、执行、反馈、修正。 这条路径同样具备闭环能力，但在可规模化上受限于物理世界，无法像代码那样高速扩张。但它的价值在于，它更接近真实世界，也更接近AGI所需要的“行动能力”。如果说代码路径训练的是“如何思考”，那么现实闭环路径训练的是“如何行动”。 最终的形态，很可能是两条路径的融合：代码能力提供“思考”，现实闭环提供“行动”，共同构成真正的 agent 系统。这也是当前从“模型”向“系统”的转变核心。AGI的路径很可能会是：先在代码中学会思考，再在现实中学会行动。

和Quant Alex @StochAlex07 讨论： SABR Theta与Spot Theta+Vol Theta+Cross Theta的异同与应用，以及SABR模型自洽性分析。 **English Summary of the Chat** **SABR Theta vs Spot Theta + Vol Theta + Cross Theta** The conversation between **Alex Wu** (white bubbles) and **Jeff Liang** (green bubbles) is a technical discussion focused on **SABR Theta versus Total Theta** (i.e., Spot Theta + Cross Theta + Vol Theta), model self-consistency, PDE residual, and the correct definition of SABR Greeks. ### Key Points Discussed: 1. **SABR Gamma = Spot Gamma** (first major question, raised by Jeff) Jeff asked whether SABR Gamma (\(\partial^2 P / \partial F^2\)) is identical to Spot Gamma and whether it includes the dependence of \(\sigma_B\) on \(F\). He also provided the full chain-rule expansion of SABR Gamma in terms of Black-76 Greeks. Alex confirmed the understanding and **later affirmed in code** that this is exactly how SABR Gamma is implemented in their system. 2. **SABR Theta vs Total Theta and Model Self-Consistency** (main topic, led by Jeff) Jeff shared a clear 3-point understanding: - SABR Theta is computed directly via the SABR approximation formula to obtain \(\sigma_B\), then applying the Black-76 chain rule: \(\partial P/\partial t =\) BS_Theta(\(\sigma_B\)) + BS_Vega \(\cdot \partial\sigma_B/\partial t\). - Total Theta is the exact decomposition from the SABR PDE (Spot Theta + Cross Theta + Vol Theta). - When the model is **fully self-consistent** (Residual = \(\partial P/\partial t + \mathcal{L}P = 0\)), SABR Theta = Total Theta; otherwise the difference is the unexplained PnL caused by the approximation error in the Hagan formula (especially pronounced in long-dated, high vol-of-vol, or high-skew options). 3. **Practical Implication – Theta Decomposition Decision** (comment by Alex) Alex noted that whether to perform Theta decomposition depends on the risk-management approach: - Without decomposition → use SABR Gamma vs. dP/dt. - With decomposition → SABR Gamma maps to Spot Theta, Vanna to Cross Theta, and Volga to Vol Theta. **Overall Tone**: The discussion is highly technical and collaborative. Jeff drives the conversation by asking clarifying questions and presenting a well-structured 3-point summary of his recent study. Alex provides confirmations, practical insights, and code-level validation. Both participants demonstrate a strong command of SABR model nuances, particularly the relationship between approximation error, PDE residual, and real-world risk management.

【5月T2写真延期更新说明 / May T2 Photo Set Update Delay Notice】 真的很抱歉，5月T2写真这个月可能没办法按原计划更新完成了。 I’m really sorry, but I won’t be able to finish the May T2 photo set updates as originally planned this month. 最近身体状态一直不太好，进度也受到了影响。虽然我本来很想尽量赶上，但现在确实有点勉强，所以决定先把身体恢复好，再继续把内容做好。 I haven’t been feeling well recently, and it has affected my progress. I really wanted to catch up if I could, but it’s honestly been a bit too difficult right now, so I’ve decided to focus on recovering first and then continue working on the content properly. 这个月没来得及完成的部分，我会延期到下个月更新。让大家等这么久，真的非常不好意思。 The content I couldn’t finish this month will be postponed and updated next month. I’m truly sorry for making everyone wait. 如果这个月有需要退款的朋友，可以直接私信联系我，我会尽快处理。 If you would like a refund for this month, please feel free to DM me, and I’ll handle it as soon as I can. 真的很感谢大家一直以来的支持和理解，也很抱歉让大家担心和失望了。我会好好调整状态，尽快回来继续更新。 Thank you so much for your continued support and understanding. I’m really sorry for causing any worry or disappointment. I’ll take care of myself and do my best to come back with updates as soon as possible.

记录我和健身小男友 一个小男友开始正面努力的满足我，我也在积极配合他，另一个小男友和我老公在一旁欣赏我的足底，感觉他们一时之间不知道该欣赏哪里，老公看着我和单男的交合处，此刻的他绿帽感满满，最后小男友精液内射在我的骚穴里流出来，第二位小男友继续接力满足我…… A Chronicle of Me and My Younger Lovers One of my younger lovers began earnestly striving to satisfy me face-to-face, and I actively reciprocated his efforts. Meanwhile, my husband and another younger lover stood by, admiring the soles of my feet—though it seemed for a moment as if they didn't quite know where to focus their gaze. My husband watched the intimate union between me and the other man, feeling utterly consumed by the sensation of being cuckolded in that moment. Finally, the young lover ejaculated deep inside my "naughty little pussy," his semen spilling back out; then, the second young lover stepped in to take up the relay and continue satisfying me... @sktwober @sktworel @sktwolris @sktwobba
