Delphi’s Dara Ladjevardian: How AI Digital Minds Can Scale Human Connection
Sequoia Capital· 2025-08-12 09:00
Let's call Adelfi right now. I'm down. Yeah. How about we call my friend? I actually haven't met him in person, but I'm I'm friends with this Deli. Arnold Schwarzenegger. Yeah. What do we think? Love it. Hey, this is AI Arnold. I'm here to cut the crap and help you get stronger, healthier, and happier. So, what's on your mind today? Arnold, I have 15 minutes a day to work out, which I feel like is not a lot, but I want to feel good and I want to get better in my health. What do you recommend I do? 15 minute ...
OpenAI Just Released ChatGPT Agent, Its Most Powerful Agent Yet
Sequoia Capital· 2025-07-22 09:00
Agent Capabilities & Architecture - OpenAI has created a new agent in ChatGPT that can perform tasks that would take humans a long time, by giving the agent access to a virtual computer [6] - The agent has access to a text browser (similar to deep research tool), a virtual browser (similar to operator tool with full GUI access), and a terminal for running code and calling APIs [6][7][8] - All tools have shared state, allowing for flexible and complex tasks [9] - The agent is trained using reinforcement learning across thousands of virtual machines, allowing it to discover optimal strategies for tool usage [3] Development & Training - The agent is a collaboration between the Deep Research and Operator teams, combining the strengths of both [6] - The agent is trained with reinforcement learning, rewarding efficient and correct task completion [36] - The model figures out when to use which tool through experimentation, without explicit instructions [38] - Reinforcement learning is data-efficient, allowing new capabilities to be taught with smaller, high-quality datasets [75][76] Safety & Limitations - Safety training and mitigations were a core part of the development process due to the agent's ability to take actions with external side effects [44] - The team has implemented a monitor that watches for suspicious activity, similar to antivirus software [48] - Date picking remains a difficult task for the AI system [4][83][84] Future Directions - Future development will focus on improving the accuracy and performance across a wide distribution of tasks [62][85] - The team is exploring different ways of interacting with the agent, beyond the current chat-based interface [68][86] - Personalization and memory for agents will be important for future development, allowing agents to do things without being explicitly asked [67][68]
Understanding Neural Nets: Mechanical Interpretation w/ Goodfire CEO Eric HO #ai #machinelearning
Sequoia Capital· 2025-07-08 18:44
Feasibility of Understanding Large Language Models - The field of mechanistic interpretability has a significant advantage due to perfect access to neurons, parameters, weights, and attention patterns in neural networks [1] - Understanding large language models is deeply necessary and critical for the future [2] - Establishing a norm to explain a percentage of the network by reconstructing it and extracting its concepts and features is crucial [2] Approaches to Understanding - Progress can be made by trying to understand all aspects of the network [2] - A baseline rudimentary understanding can be used to improve and understand more of the network [3]
Passing the Turing Test w/ ElevenLabs' Mati Staniszewski #ai #nextgenai #machinelearning
Sequoia Capital· 2025-07-01 20:46
Goal & Timeline - The company aims to achieve human-like conversational AI, potentially passing the Turing test with an agent, possibly by the end of the year or early 2026 [1][2] - The timeline depends on whether the model will be cascading (speech-to-text-to-speech) or a truly duplex "omni model" [3] Model Architecture - The company is developing both cascading and duplex models, with the cascading model currently in production and the duplex model soon to be deployed [4] - The industry faces a reliability versus expressivity trade-off between the two models [5] Trade-offs & Challenges - The duplex model is expected to be quicker and more expressive but potentially less reliable, while the cascaded model is more reliable and can be extremely expressive but may lack contextual responsiveness [5] - Latency is a significant engineering challenge, especially in fusing modalities of language models with audio [5] - No company has successfully fused language models with audio well, and the company hopes to be the first [5]
The Origins of 'Member of the Technical Staff' at OpenAI - Former Chief Research Officer Bob McGrew
Sequoia Capital· 2025-06-17 19:22
Organizational Structure & Culture - OpenAI aimed to eliminate the distinction between engineers and researchers to foster collaboration and innovation [2] - The company wanted to create a level playing field by calling everyone "member of the technical staff," regardless of their academic background [5] - OpenAI values individuals who understand the full technology stack, emphasizing the importance of hands-on experience with data and implementation [3][4] Research & Development - The company believes that researchers should act like artists, implying a creative and exploratory approach to problem-solving [5] - OpenAI recognizes that many of its great researchers learned their trade by working at the company, highlighting the importance of practical experience [5] - The organization emphasizes the significance of closely examining data to understand its possibilities, as exemplified by Alec Radford's approach [3][4]
AI Powered Software Development: Rising Demand and Changing Dynamics w/ OpenAI's Codex Team
Sequoia Capital· 2025-06-12 19:09
Market Trend - The number of professional software developers is expected to increase over time due to the increasing ease of software development [1] - There is a growing demand for bespoke software tailored for specific individuals or teams [2] Productivity Impact - Software development tools act as a multiplicative factor, enhancing developer productivity rather than replacing them [3][4] - Top users of certain software development tools are observed to be making 10+ pull requests (PRs) every day [3] - The bar to creating software is being lowered [4] Future Outlook - The long-term impact of these tools on the software development landscape remains uncertain, requiring close monitoring [4]
OpenAI Codex Team: From Coding Autocomplete to Asynchronous Autonomous Agents
Sequoia Capital· 2025-06-10 09:00
In my opinion, the the easier it is to write software, then the more software we can have. Right now, if we think of like I bet you if we look pull up our phones, well, you folks are investors. But if you're not an investor, I bet you if you pull up your phone, most of the apps on it are apps that are built by large teams for millions of users.And there's very few apps that are built like just for us and the specific thing that we need. Um, and so I think as it becomes more and more practical to build like ...
