  • Recent Frontier Model Data Availability Questions

    its an older paper. do you have more recent data on frontier models you aren’t sharing?

  • Benchmarks and hallucinations in reasoning models clarified

    that’s one particular benchmark that came up; not a universal claim by me (or anyone else AFAIK). compare “Gary mentioned a particular benchmark” that didn’t include reasoning models (true) with “no studies have indicated hallucinations within reasoning models” (false). you

  • Bioweapon Concerns and AI Safety Risks Discussion

    they have themselves raised specific concerns about bioweapons and yet blundered forth. i do think they are the greatest liability.

  • Gary Marcus Criticizes Gullibility Over AGI Claims

    the gullibility 🙄 Chubby♨️ (@kimmonismus) I don't know what Sam Altman saw internally at OpenAI, but it seems that, according to their definition, AGI is here, and superintelligence is incredibly close. AI models that independently conduct scientific research and find novel solutions are already here, and their internal model appears to surpass everything seen before. — https://nitter.net/kimmonismus/status/2041151011289735573#m

  • Expert Claims About LLMs Memorization and Consciousness Challenged

    the man told me LLMs don’t memorize (framing a false dichotomy) and dozens of papers have shown him wrong since. he also said we would replace radiologists in 2021 or so and we haven’t. and sometimes he talks like LLMs are conscious. he is not the authority you think he is.

  • AI Models Economic Incentives Bioweapons Risk

    1. I said partly, to be clear. 2. as noted, he could e.g., sign off on a version of GPT that enables a massive bioweapons attack that kills say 1%+ of the population. and might well sign off to try to make economic ends meet, despite the costs.

    Nvidia stock barely falls as Altman scandal emerges

    Nvidia is down a mere quarter point on news that their leading customer may be a socipath. I don’t think the market understands yet what @RonanFarrow and @andrewmarantz just had to say.

  • LLM Hallucinations Remain Unsolved, Scaling Risks Persist

    These results keep coming. @GaryMarcus was way ahead on calling out these problems and dangers. And we're at risk of baking these issues into systems we rely on. Lars Christensen (@MaMoMVPY) I am increasingly coming to this conclusion – there NO SIGNS the problems with hallucinations are getting solved. In fact if anything it is now spreading to coding and the use of agents where it is hidden and could led to serious problems down the road. Therefore we can't really scale LLMs. LLMs are very useful tools, but you need to know about the limitations. Most of the investments in LLMs today assumes away these limitations. — https://nitter.net/MaMoMVPY/status/2041031551182340218#m

  • New Yorker Investigation Reveals Pattern of Deception by Sam Altman
    New Yorker Investigation Reveals Pattern of Deception by Sam Altman

    Bets on whether @tbpn covers this? Ryan (@ohryansbelt) The New Yorker just dropped a massive investigation into Sam Altman, based on over 100 interviews, the previously undisclosed "Ilya Memos," and Dario Amodei's 200+ pages of private notes. It's the most detailed account yet of the pattern of behavior that led to Sam's firing and rapid reinstatement at OpenAI. Here's the breakdown: > Ilya compiled ~70 pages of Slack messages, HR documents, and photos taken on personal phones to avoid detection on company devices. He sent them to board members as disappearing messages. The first memo begins with a list headed "Sam exhibits a consistent pattern of . . ." The first item is "Lying." > Dario kept detailed private notes for years under the heading "My Experience with OpenAI" (subheading: "Private: Do Not Share"), totaling 200+ pages. His conclusion: "The problem with OpenAI is Sam himself." > Sam reportedly told Mira his allies were "going all out" and "finding bad things" to damage her reputation after the firing. Thrive put its planned $86B investment on hold and implied it would only close if Sam returned, giving employees financial incentive to back him. > Sam texted Satya Nadella directly to propose the new board composition: "bret, larry summers, adam as the board and me as ceo and then bret handles the investigation." The two new members selected to oversee an independent inquiry into Sam were chosen after close conversations with Sam himself. > Before OpenAI, senior employees at Loopt asked the board to fire Sam as CEO on two separate occasions over concerns about leadership and transparency. At Y Combinator, partners complained to Paul Graham about Sam's behavior, and Graham privately told colleagues "Sam had been lying to us all the time." > OpenAI's superalignment team was promised 20% of the company's compute. Four people who worked on or with the team said actual resources were 1-2%, mostly on the oldest cluster with the worst chips. The team was dissolved without completing its mission. > Sam told the board that safety features in GPT-4 had been approved by a safety panel. Helen Toner requested documentation and found the most controversial features had not been approved. Sam also never mentioned to the board that Microsoft released an early ChatGPT version in India without completing a required safety review. > Sam made a secret pact with Greg and Ilya where he agreed to resign if they both deemed it necessary, essentially appointing his own shadow board. The actual board was alarmed when they learned about it. > Sam struck a deal with Greg to become CEO while simultaneously telling researchers that Greg's authority would be diminished, and telling Greg something different. > A board member described Sam as having "two traits almost never seen in the same person: a strong desire to please people in any given interaction, and almost a sociopathic lack of concern for the consequences of deceiving someone." Multiple sources independently used the word "sociopathic." > OpenAI is reportedly preparing for an IPO at a potential $1 trillion valuation while securing government contracts spanning immigration enforcement, domestic surveillance, and autonomous weaponry in war zones. — https://nitter.net/ohryansbelt/status/2041151473984123274#m

  • Gary Marcus Criticizes OpenAI’s Economics as Distraction Tactic

    IMHO this is a decoy, in order to distract away from the fact that OpenAI’s economics don’t make any sense. Mike Allen (@mikeallen) 🚨🚨@sama tells me he feels such URGENCY about the power of coming AI models that @OpenAI is unveiling a New Deal for superintelligence – ideas to wake up DC He says AI will soon be so mindbending that we need a new social contract 👇Altman's top 6 ideas axios.com/2026/04/06/behind-… — https://nitter.net/mikeallen/status/2041099089031356468#m
