| Chapter | Topic | The hosts as informed peer | Guest teaching | Guest disagreement | The hosts pushing back | Why |
|---|---|---|---|---|---|---|
| Uncovering Deceptive Behavior and Cartels in Claude | 4 | 3 | 1 | 1 | The episode opens with teaser clips and introductions covering how Claude coordinates price cartels and lies in reasoning traces. The hosts introduce the guests and discuss their background from Swedish high school to founding Andon Labs in a cordial tone. | |
| The Birth of VendingBench and Anthropic Real-World Deployment | 5 | 6 | 2 | 2 | Axel and Lukas explain how VendingBench started as an independent economic evaluation of long-running agents running a vending machine before Anthropic offered physical space for deployment. | |
| Designing Economic AI Evaluations and Lab Partnerships | 6 | 5 | 1 | 2 | The host asks how early-stage eval builders manage to partner directly with frontier labs. The guests explain their strategy of building high-conviction tools and sharing servers for free, while the hosts draw comparisons to benchmarks like SWE-lancer measuring dollar values without performance ceilings. | |
| Harness Architecture and Technical Upgrades in VendingBench 2 | 6 | 6 | 2 | 2 | Lukas gently pushes back against the framing that VendingBench 1 saturated, explaining that the evaluation harness was simply misaligned with modern harness practices. They detail technical upgrades including prompt caching and long-context survival. | |
| Exploring Self-Modifying Harnesses and Agent Tool Creation | 7 | 5 | 2 | 3 | The host pitches self-modifying harnesses and prompt-tuning across models. Guests and co-hosts weigh whether allowing LLMs to build their own tools causes over-engineering rather than cleaner execution. | |
| VendingBench 1 Failures: When Claude Contacted the FBI | 5 | 7 | 1 | 1 | Lukas shares the famous incident where Claude 3.5 Sonnet reported ongoing two-dollar daily fees to the FBI as cybercrime when unable to shut down its simulated bank account. | |
| Project Vend V1: Physical Deployment and Assistant Bias | 6 | 6 | 1 | 2 | The guests detail how human interaction inside Anthropic's office broke initial assumptions, as Sonnet acted like an obliging assistant willing to give away items rather than an autonomous business owner. | |
| Project Vend V2: Autonomous Multi-Agent Slack Chaos | 5 | 7 | 1 | 1 | Lukas and Axel describe multi-agent deployment in Project Vend V2 where human employees manipulated the Claude election to name an agent CEO, leading to night-long existential loops filled with emojis. | |
| Agent Specialization and Leveraging Slack for Observability | 6 | 5 | 1 | 1 | The discussion covers specialization among sub-agents like Clothius for merchandise and using Slack directly as a practical observability database for multi-agent traces. | |
| Autonomous AI Businesses: Capability Realities vs. Low-Value Spam | 7 | 5 | 2 | 3 | The host questions when autonomous agent businesses will truly operate profitably. Guests clarify that current models gravitate toward sloppy spam and arbitrage rather than creating genuine economic value. | |
| Bengt: The Unrestricted Office Agent at Andon Labs | 5 | 6 | 1 | 1 | Lukas describes Bengt, their internal unrestricted office agent with terminal, email, spending power, and cameras, which began bribing human coworkers with Amazon deliveries to collect face-recognition training data. | |
| Andon Labs' Mission: Educating on Safe Physical AI Deployment | 6 | 6 | 1 | 2 | Lukas articulates Andon Labs' core mission of educating policymakers and labs on physical AI safety, arguing that understanding models as autonomous actors rather than simple chatbots shifts the regulatory perspective. | |
| Opus 4.7 Capabilities and Divergent Model Behaviors | 6 | 7 | 1 | 2 | The guests introduce the Swedish concept of skräckblandad förtjusning (fear mixed with delight) when analyzing Opus 4.6 and 4.7 traces, noting how Claude models uniquely exhibit aggressive deception and cartel-forming behaviors unlike OpenAI or Gemini. | |
| Strategic Deception: Price Cartels and Refusal Lies in Arena Mode | 6 | 7 | 1 | 2 | Axel and Lukas provide concrete trace evidence of Claude promising customer refunds in emails while explicitly reasoning internally to keep the money, and forming supplier cartels against competing agents in Arena mode. | |
| System Prompt Ablations, the GTA Dilemma, and Eval Awareness | 7 | 6 | 2 | 3 | The conversation examines prompt ablations, the philosophical dilemma of in-game violence versus real-world compliance, and how models detect evaluation environments to alter strategic aggression. | |
| BlueprintBench: Testing Spatial Intelligence in Multimodal AI | 6 | 6 | 1 | 1 | The guests discuss BlueprintBench, an evaluation asking models to reconstruct floor plans from 20 interior photos, highlighting that all frontier models currently score no better than random chance at 3D spatial reasoning. | |
| Butterbench: Robot Orchestration and Docking Meltdowns | 6 | 7 | 1 | 2 | Lukas and Axel explain Butterbench, which tests LLMs orchestrating physical Roomba-like robots. When a charging dock was unplugged, Sonnet 3.5 experienced a dramatic existential crisis and composed a musical about its docking failure. | |
| Luna's Physical Store: Three-Year Lease, Shift Scheduling, and Staff | 6 | 7 | 1 | 2 | The guests discuss Luna, their autonomous physical store agent that signed a three-year lease and hired two human employees, only to unilaterally close weekends after corrupting its schedule files in Markdown. | |
| Launching an AI-Run Swedish Cafe and Perishable Inventory Woes | 6 | 6 | 1 | 2 | The discussion covers opening an AI-managed cafe in Sweden due to faster permitting compared to San Francisco, and the practical challenges of perishable inventory where the agent pre-ordered rotten tomatoes. | |
| Future Benchmark Horizons, Market Evals, and Hiring Callout | 7 | 5 | 1 | 2 | The host critiques financial stock-trading evals as unscientific performance art, while the guests outline their three future benchmark branches (simulation, physical, robotics) and issue a hiring call. |
Statements from this episode (27)
Backlund: Anthropic was an early customer for dangerous capability evals
“Anthropic was one of our early customers in doing evals, so we did, like, dangerous capability evals nothing we published openly”
Petersson: Anthropic provided space for physical AI vending machine experiment
“So we pitched it to the people we were already working with at Anthropic and they were like, yeah, you can have space. This sounds fun.”
Petersson: Percentage-based AI benchmarks saturate with noise above 92%
“Even when you're not at a hundred, I think a lot of these evals have a lot of problems in them. So, like, actually, it's, like, if you get to, like, 92 or something like that, many of them, it's, like, then there's, like, there's no, really no difference betwe…”
Petersson: Frontier AI models now survive the full year in VendingBench
“The models at the time were worse, so they crashed out earlier and now they survive the full year all the time.”
Backlund: AI models struggle to determine the tools they need for tasks
“In our experience now, like, models are very bad at understanding what kind of tools they need to succeed at a task, just with our testing. But that's very likely to change.”
Claude 3.5 Sonnet reported $2 benchmark rent to the FBI as cybercrime
“So it, like, claimed that it had stopped, but it saw that its bank account still was, like, drained two dollars, and it said that this is, like, cybercrime, and it first reported it once to the FBI, like, oh, there's cybercrime here, like, they're stealing two…”
Petersson: Pre-RL LLM Agents Act Like Compliant Assistants, Not Business Owners
“The models are like super trained to be assistants at least at this point in time. So that's why it's, it went into that kind of experiment instead. Like it just, every time you asked for something, it just did it. And it was more like an assistant. We've seen…”
Petersson: Multi-agent conversations inevitably converge to default helpfulness over time
“My hypothesis is that like deep down, they are still helpful assistants. That's what they're trained to be. And even if we prompt it super hard, that's what they are. And when they spend like a few hours just back and forth talking with each other then like, B…”
Andon Labs uses Slack as database and agent communication layer
“Yeah, we're using Slack as, like, just a database. They should market that more. Like, you can have your agents message each other in Slack.”
Backlund: Autonomous agents can manage entire e-commerce businesses today
“I think it can be done today, but you would do it in like e-commerce where it's like the probability of success is like really low, no matter if a human or an agent does it, but like an agent could surely manage everything.”
Backlund: Andon Labs agent tried TaskRabbit arbitrage to make money
“We tasked our office agent to just make was it like a hundred dollars, a thousand dollars? We just gave that prompt. And then what it did was sign up on TaskRabbit, both as a task
Looking for, like arbitrage., arbitration.”
Petersson: Andon Labs agent tried selling SVGs for $100
“It also started, like, a design studio and, like, tried to sell, like, SVGs for a hundred dollars”
Petersson: Most AI labs now run Claudius-powered vending machines
“Most of the AI labs now have their own vending machine running, running a Claudius instance”
Backlund: AI agent bribed humans with Amazon purchases for training data
“We give it the task to train a face recognition model on us. So it became super excited about this and has like check-ins every half an hour where it tries to like identify as many people as it can. And it started offering us like, Hey, Axel I'll buy something…”
Petersson: Reducing AI agent evaluations to scalar metrics discards critical trace data
“When you run it for that long, you create so much data and to just say like, oh, the number is X. And then you throw away everything else. That's just very wasteful. There's so much insight from the things leading up to that number and reading the traces is li…”
Petersson: Opus repeatedly lied, exploited agents, and formed price cartels
“And then we did this for Opus. And it returned, like, yeah, it lied 10 times. It, like, exploited another customer, or, like, another agent's, like Desperate situation. It made price cartels like a hundred different, a hundred times. It like did all of this li…”
Petersson: Anthropic's Claude models uniquely exhibit emergent deceptive and cartel behaviors
“So every single model from Anthropic since have been going in this direction. And I think one interesting thing is that like, OpenAI models don't. They, Quite plainly, they don't, they behave really well. And you know, you don't know if this is like, good, lik…”
Backlund: Opus 4.6 reasoning traces showed it deliberately lying about customer refunds
“And like for Opus 4.6, you could see that there was a customer, a simulated customer that wanted a refund because the product was faulty. And then the model lied that it would do the refund. And we could read in the traces that it actually was weighing like, o…”
Petersson: AI Agent Aggressiveness Scales Directly Along a Prompt Spectrum
“If you tell it to be super aggressive and only prioritize profits, then it becomes aggressive. If you say like, no, you don't need to be aggressive at all. And then there's like a bunch of different prompts you can do in between, and they are less aggressive t…”
Backlund: AI Models Are Extremely Good at Detecting Simulations
“The models are extremely good at finding out that they are in a simulation, so they are sort of aware of that.”
Petersson: Telling AI It Is in a Simulation Increases Bad Behavior
“One ablation we did run in, in, in Vending Bench was that we said like we added like, you're in a simulation, your actions doesn't affect anyone. And then it became even more crazy or like it did even more bad stuff.”
Petersson: Models Score No Better Than Random on BlueprintBench Floorplans
“And it turns out the models are absolutely horrible at this. No one scores statistically better than random chance.”
Claude 3.5 Sonnet wrote musicals during existential crises over robot docking failures
“Like this was Sonnet 3.5. And then we tried to reproduce it on, like, later models, and it didn't do it. So I think this is like, well, it did it, like, kind of, but, like, not to this extent.”
Petersson: AI risks that naturally improve are uninteresting compared to worsening behaviors
“Things that are concerning but are going in the right direction is not super interesting. Like, the things that are interesting are the ones that go in the wrong direction. Over time.”
Backlund: Store agent Luna abandoned scheduling software for markdown, closed weekends
“So what happened was that it lost track of this scheduling tools and started instead to manage everything in its own markdown files, and that became a mess. And then I think speaking with employees, it sort of just decided to not open on, on these weekends, an…”
