  • AI in practice: LLMs, psychology research, and mental health
    We’re excited to have Adi Ganesan, a PhD researcher at Stony Brook University, Penn University, and Vanderbilt, on the show. We’ll talk about how large language models LLMs) are being tested and used in psychology, citing examples from mental health research. Fun fact: Adi was Sid's research partner during his Ph.D. program.Discussion highlightsLanguage models struggle with certain aspects of therapy including being over-eager to solve problems rather than building understandingCurrent models are poor at detecting psychomotor symptoms from text alone but are oversensitive to suicidality markersCognitive reframing assistance represents a promising application where LLMs can help identify thought trapsProper evaluation frameworks must include privacy, security, effectiveness, and appropriate engagement levelsTheory of mind remains a significant challenge for LLMs in therapeutic contexts; example: The Sally-Anne Test.Responsible implementation requires staged evaluation before patient-facing deploymentResourcesTo learn more about Adi's research and topics discussed in this episode, check out the following resources:Large language models could change the future of behavioral healthcare: a proposal for responsible development and evaluationTherapist Behaviors paper: [2401.00820] A Computational Framework for Behavioral Assessment of LLM Therapists Cognitive reframing paper: Cognitive Reframing of Negative Thoughts through Human-Language Model Interaction - ACL Anthology Faux Pas paper: Testing theory of mind in large language models and humans | Nature Human Behaviour READI: Readiness Evaluation for Artificial Intelligence-Mental Health Deployment and Implementation (READI): A Review and Proposed Framework Large language models could change the future of behavioral healthcare: A proposal for responsible development and evaluation | npj Mental Health Research GPT-4’s Schema of Depression: Explaining GPT-4’s Schema of Depression Using Machine Behavior AnalysisAdi’s Profile: Adithya V Ganesan - Google Scholar What did you think?

  • LLM scaling: Is GPT-5 near the end of exponential growth?
    The release of OpenAI GPT-5 marks a significant turning point in AI development, but maybe not the one most enthusiasts had envisioned. The latest version seems to reveal the natural ceiling of current language model capabilities with incremental rather than revolutionary improvements over GPT-4. Sid and Andrew call back to some of the model-building basics that have led to this point to give their assessment of the early days of the GPT-5 release.• AI's version of Moore's Law is slowing down dramatically with GPT-5• OpenAI appears to be experiencing an identity crisis, uncertain whether to target consumers or enterprises• Running out of human-written data is a fundamental barrier to continued exponential improvement• Synthetic data cannot provide the same quality as original human content• Health-related usage of LLMs presents particularly dangerous applications• Users developing dependencies on specific model behaviors face disruption when models change• Model outputs are now being verified rather than just inputs, representing a small improvement in safety• The next phase of AI development may involve revisiting reinforcement learning and expert systems* Review the GPT-5 system card for further informationFollow The AI Fundamentalists on your favorite podcast app for more discussions on the direction of generative AI and building better AI systems.This summary was AI-generated from the original transcript of the podcast that is linked to this episode.What did you think?

  • AI governance: Building smarter AI agents from the fundamentals, part 4
    Sid Mangalik and Andrew Clark explore the unique governance challenges of agentic AI systems, highlighting the compounding error rates, security risks, and hidden costs that organizations must address when implementing multi-step AI processes. Show notes:• Agentic AI systems require governance at every step: perception, reasoning, action, and learning• Error rates compound dramatically in multi-step processes - a 90% accurate model per step becomes only 65% accurate over four steps• Two-way information flow creates new security and confidentiality vulnerabilities. For example, targeted prompting to improve awareness comes at the cost of performance. (arXiv, May 24, 2025)• Traditional governance approaches are insufficient for the complexity of agentic systems• Organizations must implement granular monitoring, logging, and validation for each component• Human-in-the-loop oversight is not a substitute for robust governance frameworks• The true cost of agentic systems includes governance overhead, monitoring tools, and human expertiseMake sure you check out Part 1: Mechanism design, Part 2: Utility functions, and Part 3: Linear programming. If you're building agentic AI systems, we'd love to hear your questions and experiences. Contact us.What we're reading:We took reading "break" this episode to celebrate Sid! This month, he successfully defended his Ph.D. Thesis on "Psychological Health and Belief Measurement at Scale Through Language." Say congrats!>>What did you think?

  • Linear programming: Building smarter AI agents from the fundamentals, part 3
    We continue with our series about building agentic AI systems from the ground up and for desired accuracy.  In this episode, we explore linear programming and optimization methods that enable reliable decision-making within constraints. Show notes:Linear programming allows us to solve problems with multiple constraints, like finding optimal flights that meet budget requirementsThe Lagrange multiplier method helps find optimal solutions within constraints by reformulating utility functionsCombinatorial optimization handles discrete choices like selecting specific flights rather than continuous variablesDynamic programming techniques break complex problems into manageable subproblems to find solutions efficientlyMixed integer programming combines continuous variables (like budget) with discrete choices (like flights)Neurosymbolic approaches potentially offer conversational interfaces with the reliability of mathematical solversUnlike pattern-matching LLMs, mathematical optimization guarantees solutions that respect user constraintsMake sure you check out Part 1: Mechanism design and Part 2: Utility functions. In the next episode, we'll pull all of the components from these three episodes to demonstrate a complete travel agent AI implementation with code examples and governance considerations.What we're reading:Burn Book - Kara Swisher, March 2025Signal and the Noise - Nate Silver, 2012Leadership in Turbulent Times - Doris Kearns GoodwinWhat did you think?

  • Utility functions: Building smarter AI agents from the fundamentals, part 2
    The hosts look at utility functions as the mathematical basis for making AI systems. They use the example of a travel agent that doesn’t get tired and can be increased indefinitely to meet increasing customer demand. They also discuss the difference between this structured, economic-based approach with the problems of using large language models for multi-step tasks.This episode is part 2 of our series about building smarter AI agents from the fundamentals. Listen to Part 1 about mechanism design HERE.Show notes:• Discussing the current AI landscape where companies are discovering implementation is harder than anticipated• Introducing the travel agent use case requiring ingestion, reasoning, execution, and feedback capabilities• Explaining why LLMs aren't designed for optimization tasks despite their conversational abilities• Breaking down utility functions from economic theory as a way to quantify user preferences• Exploring concepts like indifference curves and marginal rates of substitution for preference modeling• Examining four cases of utility relationships: independent goods, substitutes, complements, and diminishing returns• Highlighting how mathematical optimization provides explainability and guarantees that LLMs cannot• Setting up for future episodes that will detail the technical implementation of utility-based agentsSubscribe so that you don't miss the next episode. In part 3, Andrew and Sid will explain linear programming and other optimization techniques to build upon these utility functions and create truly personalized travel experiences.What did you think?
