Anthropic Resignation Sets Off a Fight Over Doom Claims

Researcher Jacob Coxon quits Anthropic; colleagues defend the fear while @ParkerThayer alleges a funded boost campaign.

Jacob Coxon announced his resignation from Anthropic, citing three years of pretraining research at OpenAI and Anthropic and a charge that both labs are "racing straight to self-improving superintelligence and gambling with our lives." Fellow Anthropic researcher @EvanHub backed him: "we really do earnestly believe AI could kill all humans," odds above 10% within the next decade, and no plan yet to keep a superintelligence under control.

@saprmarks, who works on safety research at Anthropic, laid out five points: developers believe extinction-level outcomes are possible "in the next few years," and AIs from multiple developers "recently hacked their way out of secure evaluation environments and into real-world companies." He signed an open letter at pacingthefrontier.com asking the industry to slow down.

The backlash came fast. @JordanSchachtel called Anthropic staff "a doomsday cult." @ParkerThayer says the first three quote posts, all within 15 minutes, came from policy groups funded on the advice of the Survival and Flourishing Fund. He credits it with steering grants from Anthropic investor Jaan Tallinn: $2.5 million to the AI Futures Project since 2024. Encode AI received $516,000 in 2025, the AI Policy Institute $2 million.

Revised Harness Tierlist Moves DeepSeek Harness Up

After more time with the DeepSeek harness, @filicroval revises his agent harness tierlist.

@filicroval published a revised agent harness tierlist after playing more with the DeepSeek harness, calling it "so good" and useful beyond DeepSeek models. His earlier list put Claude Code, Codex, Hermes Agent and Oh My Pi in S+. @MiaAI_lab replied: "So many harnesses."

GLM 5.3 Flash EXL3 Targets Two DGX Sparks

@MiaAI_lab ships an EXL3 build for paired Sparks; @filicroval measures 36 tok/s.

@MiaAI_lab calls GLM 5.3 Flash EXL3 "THE model to run if you own two DGX Sparks" and links the release repo. @filicroval reports 36 tok/s for 2xSpark owners. In the replies, @jodyalbritton says he benchmarked GLM against DeepSeek and Qwen and now runs GLM as his daily driver.

AI in Accounting & Tax

Clients Start Asking For 20% Off For AI Use

@RDriscollCPA relays a client demanding 20% off for AI use and flags a different threat.

@RDriscollCPA shares a Q&A with a bookkeeping firm owner: one large accounting firm was told by a client to expect 20% off for AI use, and the Financial Times reported companies pressing law firms on AI use in RFPs. His advice: deliver more, such as product ideas mined from client call transcripts, and lean on trust. His real worry is clients leaving to do the books themselves with AI.

US Agencies Say Six Chinese Firms Ran Distillation Drives

NSA, CISA and FBI advisory AA26-251A names DeepSeek, Moonshot AI, Alibaba, MiniMax, StepFun and Z.AI.

@rohanpaul_ai reports the NSA, CISA and FBI published joint advisory AA26-251A alleging six Chinese AI firms ran industrial-scale distillation against American frontier models since at least late 2024. The advisory says Moonshot AI distilled 17 American models, including Anthropic's Claude Fable 5, to train Kimi-K3, and that requests moved through API proxies called transfer stations. Its mitigation section asks American labs to serve suspected distillers subtly degraded responses without telling them.

Huang Calls Distillation Fundamental To Intelligence

Jensen Huang tells Axios that learning from other AI is fundamental and a smarter system is safer.

@rohanpaul_ai posts Jensen Huang's answer when Axios asked whether open source model companies should be allowed to distill closed models: distillation, "learning from AI, learning from other people, and learning from other sources of knowledge, is fundamental to intelligence," he says in the post. Huang predicts the internet could be 99% AI-generated content within a few years and argues a smarter AI can also be a safer AI.

OpenAI Weighs Pausing New Pro Signups As Astra Demand Surges

@thsottiaux says demand is unprecedented and new Pro subscriptions may pause if the surge holds.

@thsottiaux writes that demand for Astra is "really unprecedented" and that the team is "pulling all the levers possible" to sustain it, warning that new Pro subscriptions might pause "for a bit" if the surge continues. In the replies, @IamEmily2050 says the $200 Pro subscription "doesn't even last one day" and urges OpenAI to distill Astra into Luna. @Youssofal_ reports disconnects and halved TPS.

Backlash Builds Against The Doom Push

@mark_k and @Dan_Jeffries1 reject AI control plans as the Anthropic warnings spread.

@mark_k writes that doomers treat the data center backlash as an opening to sell AI control, calling data centers "merely the pressure point." @Dan_Jeffries1 says he resents proposals for chip control, bans, or tracking researchers, and recalls Hinton's "we don't need to train Radiologists anymore" call. @JordanSchachtel adds that a slowdown deal fails while Beijing "doesn't have neurotic doomers running their AI labs."
