I'm ecstatic to share that preorders are now open for the AI Snake Oil book! The book will be released on September 24, 2024. @random_walker and I have been working on this for the past two years, and we can't wait to share it with the world. Preorder:

GPT-4 memorizes coding problems in its training set. How do we know? @random_walker and I prompted it with a Codeforces problem title. It outputs the exact URL for the competition, which strongly suggests memorization.

As developers increase inference compute, per-token cost becomes a worse proxy for the actual cost of running a model. Two-dimensional leaderboards (accuracy vs. cost) are necessary. We analyze the impact of inference compute in AI Agents That Matter:
o1-preview can be >30X more expensive than GPT-4o, despite the per token price being ~6X higher. o1-preview per token price is only half the story when considering the cost of queries. In our testing of 30 diverse prompts, o-1 preview was much more verbose than GPT-4o, generating

The issue with the malicious plugin framing is that the plugin needn't be malicious at all! The security threat arises LLMs process instructions and text inputs in the same way. In my example, WebPilot certainly wasn't responsible for the privacy breach.
@sayashk ChatGPT plug-ins are in early beta. If you find such a problem in any MS products, please do share! We’re certainly intending to guard against malicious plugins (and any unintended use of plugins).

Our latest on AI Snake Oil: How AI vendors do a bait-and-switch through 4 case studies. 1) Toronto's beach safety prediction tool.2) Epic's sepsis prediction model.3) Welfare fraud prediction in the Netherlands.4) Allegheny county's family screening tool.
AI risk prediction tools are sold on the promise of full automation, but when they inevitably fail, vendors hide behind the fine print that says a human must review every decision. @sayashk and I analyze this and other recurring AI failure patterns.

One of the most interesting things our agent did was searching the web instead of actually solving the benchmark task. We did not anticipate this and had no web filters, but thankfully the agent couldn't load the results because they require Javascript.

More on the shortcomings of GPT-4’s evaluation in our latest blog post:
OpenAI may have tested GPT-4 on the training data: we found slam-dunk evidence that it memorizes coding problems that it's seen. Besides, exams don't tell us about real-world utility: It’s not like a lawyer’s job is to answer bar exam questions all day.

@random_walker We found that (1) half of AI use wasn't deceptive, (2) deceptive content was nevertheless cheap to replicate without AI, and (3) focusing on the demand for misinfo rather than the supply can be more effective. Link to the essay:

If you have been anywhere near AI discourse in the last few months, you might have heard that AI poses an existential threat to humanity. In today's Wall Street Journal, @random_walker and I show that claims of x-risk rest on a tower of fallacies.
🧵@sayashk and I rebut AI x-risk fears (WSJ debate).–Speculation (paperclip maximizer) & misleading analogies (chess) while ignoring lessons from history.–Assuming that defenders stand still.–Reframing existing risks as AI risk (which will *worsen* them).

Very interesting paper on overreliance in LLMs, led by @sunniesuhyoung. The results on overreliance are very interesting, but equally fascinating is the evaluation design: they random assign users to different LLM behaviors + check against a baseline with internet access.
There is a lot of interest in estimating LLMs' uncertainty, but should LLMs express uncertainty to end users? If so, when and how? . In our #FAccT2024 paper, we explore how users perceive and act upon LLMs’ natural language uncertainty expressions. 1/6

@random_walker The use of checklists and model cards has been impactful in improving reporting standards. Model info sheets are inspired by @mmitchell_ai et al.'s model cards for model reporting (, but are specifically focused on addressing leakage.

@random_walker Writing for a broad audience is very different from academic writing. Steven Pinker's "The Sense of Style" helped me make the transition. It was also useful to go back to some of my favorite general-audience books to dissect how engaging non-fiction is written.

@random_walker @mmitchell_ai Taking a step back, why do we say ML-based science is in crisis? There are two reasons: First, reproducibility failures in fields adopting ML are systemic—they affect nearly every field that has adopted ML methods. In each case, pitfalls are being independently rediscovered.

OpenAI's policies are bizarre: it deprecated Codex with a mere 3 days of notice, and GPT-4 only has snapshots for 3 months. This is a nightmare scenario for reproducibility. Our latest on the AI snake oil blog, w/@random_walker
Language models have become privately controlled research infrastructure. This week, OpenAI deprecated the Codex model that ~100 papers have used—with 3 days’ notice. It has said that newer models will only be stable for 3 months. Goodbye reproducibility!
