Anthropic CEO: “ I have engineers within anthropic who don’t write any code, they just let Claude write the code and they edit it and look it over” “At anthropic writing code means designing the next version of Claude it self, so we essentially have Claude designing the next version of Claude itself, not completely but most of it”. In the last 52 days, the Claude team dropped 50+ major feature launches. This is literally INSANE.

@aarondotdev Did you read the paper? It studied junior devs *learning* a new library. The ones who used AI to understand concepts scored just as well as the no-AI group. The ones who copy-pasted blindly didn't. The conclusion isn't "AI is bad", it's that you need "think while you use AI".

Anthropic themselves found that vibecoding hinders SWEs ability to read, write, debug, and understand code. not only that, but AI generated code doesn’t result in a statistically significant increase in speed don’t let your managers scare you into increased productivity. show them this paper straight from Anthropic.

@erroneous_input @ns123abc @sama The pentagon agreed to the terms of Anthropic (i.e "no use for fully autonomous or mass surveillance of Americans") but they added the redline "except bulk data analysis" which is the same as saying they can use it for anything, because any AI system does bulk data analysis...

@ns123abc @sama i’m not sure i understand here. you said that he claimed they agreed to all terms except bulk data analyses. the fact he would reject that is unhinged. but besides that, how can it be claimed OAI agreed to palantir’s offer if the only holdout was bulk data?

🚨BREAKING: ANTHROPIC CEO JUST ENDED OPENAI @sama After getting blacklisted by Pentagon, Dario sits down and writes the most unhinged CEO memo in silicon valley history: >calls openai's pentagon deal "safety theater" >says trump admin hates them because they haven't "given dictator-style praise to Trump (while Sam has)" >names greg brockman's $25M trump super PAC donation by name says they supported AI regulation >"which is against their agenda" >says they "told the truth about AI policy issues like job displacement" THE PALANTIR EXPOSÉ: >reveals palantir's actual pitch to anthropic during negotiations >"you have some unhappy employees, you need to offer them something that placates them or makes what is happening invisible to them, and that's the service we provide" >palantir's pitch wasn't safety. it was CONCEALMENT >palantir offered a "classifier" to detect red line violations >dario: models get jailbroken, monitoring only works in a few cases "maybe 20% real and 80% safety theater" >says palantir offered openai the same package >openai accepted it >says Altman is "peddling narratives" to his own employees >calls openai employees "sort of a gullible bunch" due to "selection effects" >says the "attempted spin/gaslighting" isn't working on >the public or media but IS working on "some Twitter morons" rofl >says his main concern is making sure it doesn't work on openai employees too BTW near the end of negotiations the pentagon offered to accept ALL of anthropic's terms if they deleted ONE phrase: >"analysis of bulk acquired data" >anthropic refused >same surveillance clause pentagon said they didn't even want to do >meanwhile Altman told his employees: "you don't get to weigh in on that" 💀 ITS OVER.

@ns123abc @sama This entire thing has been political from the very beginning. Anthropic is lying because they don't like Trump. The Pentagon on never asked for what anthropic claims they did. They simply don't think a private company should have a kill switch on military weapons platforms.

@vdub12 @JoelStransky @ns123abc @sama If you think the AI is a military weapons system you are very wrong. The AI can support the creation of autonomous military weapons, but is far from being a weapon on its own. It would be the same as saying a bullet is a weapon if you have no gun.

@JoelStransky @ns123abc @sama What does that have to do with what I said? The Pentagon offered them a contract but did not want them to retain control of a military weapons system. It's not like Boeing builds aircraft but then the military has to ask permission to use the keys.

It will significantly increase my opinion of @Anthropic if they do not back down, and honorably eat the consequences. (For those who are not aware, so far they have been maintaining the two red lines of "no fully autonomous weapons" and "no mass surveillance of Americans". Actually a very conservative and limited posture, it's not even anti-military. IMO fully autonomous weapons and mass privacy violation are two things we all want less of, so in my ideal world anyone working on those things gets access to the same open-weights LLMs as everyone else, and exactly nothing on top of that. Of course we won't get anywhere close to that world, but if we get even 10% closer to that world that's good, and if we get 10% further that's bad) CC @DarioAmodei firefly.social/post/bsky/pv7f…

Excited to share a preview of @SnorkelAI 's new Agentic Coding benchmark - testing models on realistic, multi-step software engineering tasks in fully sandboxed execution environments across a calibrated range of task domains and difficulties, inspired by our work with the @terminalbench team! With a top pass@5 score of 58% (Opus 4.5) - this new benchmark challenges the notion running wild on X right now that LLMs have "solved" software engineering. And, with both unit tests and both final-output and trajectory-level rubrics, it's already giving us & partners insights into where coding agents fail. Excited to share more here shortly!

OpenAI and Anthropic have opposite cultures. OpenAI runs like a modern Bell Labs. 2-3 researchers spin up projects like GPT & Sora, then turn them into products. Maximal ambition, from each kind of model to robotics to AI device. Anthropic is brutally focused. They believe coding is the path to AGI. Everything else is noise. No image models. No video models. No vagueposts. It will be fascinating to see which one wins.

Don't say: "vLLM is fastest" or "Ollama is easiest." Wrong framing. The real answer isn't about features - it's about matching serving philosophy to your constraints. Local prototype vs. production scale vs. complex workflows = completely different frameworks.

I rejected a job offer yesterday. Not because of the salary. Not because of the tech stack. Not even because of the long hours they warned me about. But because, when I asked how they evaluate their AI systems, the hiring manager said: "We just ask it some questions and see if the answers sound right." I stared at them for a moment and realized... They just described the biggest problem in AI today. See, "sounds right" isn't a measurement. It's a hope. Here's what proper LLM evaluation actually looks like: - Accuracy: Can it get factual questions right? (Not 80% of the time. Consistently.) - Hallucination rate: How often does it make things up? (This should be near zero for critical applications.) - Bias metrics: Does it treat all groups fairly? (Measured across demographics, not assumed.) Real Evaluation Frameworks: - BLEU scores for translation quality Perplexity for language modeling Human evaluation with inter-annotator agreement Adversarial testing (red teaming) Domain-specific benchmarks (legal, medical, financial) The Process: > Define success criteria BEFORE deployment > Create diverse test sets (not just happy paths) > Measure consistently across model versions > Track performance over time (models drift) Have humans validate edge cases Why This Matters: Before proper evals: "Our model is amazing!" (based on cherry-picked examples) After proper evals: "Our AI achieves 94.2% accuracy on domain X, with known failure modes Y and Z" The difference? One builds trust. The other destroys it when reality hits. The kicker: Most companies are still in the "sounds right" phase. They're deploying models evaluated by vibes, not metrics. Just like you wouldn't join a team that deploys code without tests, you shouldn't join one that deploys AI without proper evaluation. What's your experience with LLM evaluation? Are we measuring what actually matters?

Tested gpt-oss-120b on @SnorkelAI 's agent benchmarks - performance seems split on real world tasks. It did well on multi-step Finance, but poorly on multi-turn Insurance. Think this could be a limitation of either domain knowledge or handling multi-turn scenarios.
