AI Graveyard: A Continuously Updated List of Failed AI Projects and Startups

TechCrunch reported on October 25, 2026, reviewing several AI projects from 2023 to 2026 that failed to meet expectations, including startups and products such as Relay, Character.ai, Sora, and Humane AI Pin, as well as failed attempts or major adjustments by major companies like OpenAI, Apple, and Microsoft.

Why it mattersThis report provides an industry‑wide, phenomenon‑driven overview, with broad coverage and a clear timeline (including specific shutdown or delay dates), and cites S&P Global Market Intelligence data to substantiate the high attrition rate—42%—of enterprise‑level AI projects. It combines detailed case studies with structural analysis, making it a highly valuable reference.

The PHP “Meltdown” incident reveals how AI can amplify the threat of legacy vulnerabilities.

Security researchers, using AI tools, have turned a PHP vulnerability—known collectively as PHP2Shell—that has existed for years and was once considered difficult to exploit—into a real-world exploitable attack surface. Within hours of the vulnerability being made public, it was already targeted in millions of exploitation attempts, yet no successful intrusions have been reported to date.

Why it mattersThis incident clearly demonstrates for the first time that AI does not create new vulnerabilities out of thin air; rather, it significantly lowers the barrier to exploiting existing vulnerabilities, highlighting AI’s dual role in accelerating both offensive and defensive security dynamics. Moreover, all valid findings rely on human–machine collaboration.

Research reveals that large language models exhibit “invisibility” bias: the rejection rate for evaluating information about Black describers reaches as high as 46%.

An empirical study published on October 24, 2026, on arXiv (paper ID 2610.30785v1) found that mainstream large language models from OpenAI and Anthropic exhibit a significant “invisibility” bias in trust assessment tasks—specifically, they systematically refuse to evaluate information when prompts contain protected attributes (such as “Black”), rather than basing their decisions on the quality of evidence; this bias is difficult to detect using conventional auditing methods.

Why it mattersThis study employs a rigorously designed two-urn Bayesian decision experiment, encompassing 6,600 sessions and 10 descriptive configurations. It is the first to quantify the cost of model‑driven rejection behavior triggered by identity labels and reveals its counterintuitive characteristics: rejection rates vary dramatically (46% for Black describers vs. 9% for White describers), yet once evaluated, Black describers actually receive slightly higher trust; moreover, bias intensifies with increasing reasoning depth, relies on specific vocabulary rather than semantics, and worsens under warning instructions—findings that carry direct implications for AI fairness assessment and alignment practices.

SIM-UT: A User Behavior Simulation and Evaluation Framework for Medical Triage Chatbots

Researchers have proposed SIM-UT (Simulation of User Behaviour for Triage), a multi-round, real-user-behavior–based evaluation method designed to identify eco‑valid failure patterns of large language model (LLM)-driven medical triage chatbots in real-world settings within low- and middle-income countries (LMICs).

Why it mattersThis framework breaks through the limitations of existing single-round, English‑centric evaluations by conducting over 5,000 rounds of multilingual simulated conversations, covering real‑world WhatsApp health programs in India, South Africa, and Kenya. For the first time, it systematically reveals “de‑escalation risk,” a critical failure mode, demonstrating both methodological innovation and significant clinical safety implications.

AI has achieved a series of breakthroughs in the field of mathematical proof: from a counterexample to the unit-distance conjecture to a proof of the Navier–Stokes equations.

From May to September 2026, OpenAI and organizations such as Anthropic reported several AI-driven mathematical breakthroughs, including disproving the Erdős unit-distance conjecture, completing a proof of the cycle double cover conjecture, advancing estimates for the Riemann hypothesis, and providing a new proof of the Navier–Stokes equations. The paper proposes a non-numeric conceptual framework to explain the limits of its capabilities, emphasizing that AI has unique advantages in high-cost, low-gradient exhaustive problems; however, none of these results have undergone independent verification or peer review.

Donating Agent Skills to the Agentic AI Foundation

Donating Agent Skills to the Agentic AI Foundation News today from Anthropic: We’re committed to keeping Agent Skills open, community-driven, and vendor-neutral. Today, we are donating the standard to the Agentic AI Foundation (AAIF) under the Linux Foundation, which we co-founded with Block and OpenAI last year, and to which we donated the Model Context Protocol (MCP). I'm pleased to note I called this one last December, when Anthropic first declared skills to be an "open standard": I wouldn't be surprised to see this end up in the AAIF, recently the new home of the MCP specification. Fun side note: since my blog content is available to Claude via the datasette-mcp plugin I found that post by prompting Claude to "Use simonwillison.net MCP to find if I ever talked about how I want skills t
