Watch on YouTube →OpenAI leaders discuss the shift from manual coding to orchestrating agentic loops. GPT 5.6 models Soul, Terra, and Luna are now the frontier.
- GPT 5.6 Luna costs $1 per million input tokens.
- Technical velocity increased from 15-month cycles to 6-week releases.
- The Codex stack includes a new Agent MD file format.
- Value Maxing balances frontier intelligence with extreme cost efficiency.
- The primary constraint for modern engineers is attention rather than token cost.
- Leverage agents to move from the inner loop of execution to the outer loop of direction.

How to Teach Yourself Anything (The Self-Study Blueprint)
Rob Dial · The Mindset Mentor Podcast · 18 min
Watch on YouTube →A blueprint for intentional learning to move from information consumption to skill mastery. The brain wires itself around repeated exposure.
- Teaching a concept is the fastest way to identify personal knowledge gaps.
- Information overload is often a lack of focus on a specific high-income skill.
- The Self-Study Blueprint involves intentional consumption, reflection, and immediate application.
- Attention is a more valuable resource than money.
- Depth of knowledge in one skill is more valuable than surface-level knowledge of many.
- Personal development collectors often use consumption as a substitute for action.
Dot Plots: How to Actually See What Your Users Are Doing
David Lieb · Y Combinator · 13 min
Watch on YouTube →YC General Partner David Lieb argues against aggregate metrics in favor of Dot Plots. This visualization reveals individual user behavior patterns.
- Aggregate metrics like DAU often mask a lack of product-market fit.
- Dot plots map individual users against time to show retention and engagement.
- Google Photos used sampled dot plots to manage a billion users.
- In B2B, dot plots identify churn risk by showing low seat activation.
- Human brains are evolved to recognize visual patterns that algorithms might miss.
- Sampling is an effective way to maintain high-granularity insights at scale.
The AI Trade Everyone's Getting Wrong
Josh · Limitless Podcast · 28 min
Watch on YouTube →Samsung and SK Hynix have become the dominant financial powers of the AI era. High Bandwidth Memory (HBM) is the new strategic bottleneck.
- Samsung reported a $58.5 billion quarterly profit, exceeding Nvidia.
- Producing 1GB of HBM consumes the factory capacity of 4GB of traditional DRAM.
- SK Hynix maintains a 72 percent profit margin on memory sales.
- Fab capacity for HBM is unlikely to meet demand until 2030.
- AI acts as a black hole for memory, requiring exponential increases in NAND flash.
- Pricing power has shifted to the Korean Duopoly due to a relative monopoly on HBM.
The rise of taste, human authenticity and judgment in an AI world | Adam Mosseri (Head of IG)
Adam Mosseri · Lenny's Podcast · 68 min
Watch on YouTube →The Head of Instagram describes a shift toward lean pods and the rise of human authenticity. AI is collapsing traditional functional silos in product development.

- The Product Staff role merges PM, design, and data science.
- Strategy must be controversial enough for a reasonable person to disagree.
- LLMs are now used to narrate the multi-dimensional vector space of the algorithm.
- Hiring priorities for the next decade include grit, quick learning, and self-awareness.
- Users will seek out human authenticity more aggressively in a world of synthetic content.
