Addy Osmani, Morgan Westlee Lunt, and Qing Wang say the Claude Code team reviews changes continuously, with Claude reviewing and fixing most changes at least once before a human looks. They describe asking what could go wrong and which check—automated or human—is right to catch it, rather than using whether a human read the code as a proxy.
Six projects from the last few weeks that caught our attention: A wildfire analysis prototype that maps the fire’s spread over time and tracks hot spots, made with Opus 5.5.
ClaudeDevs announced that Code Review is now generally available for Claude Team and Enterprise plans, with faster reviews, improved detection of consequential bugs, and per-repo Quick, Standard, or Deep review levels selected by admins. Boris Cherny says it runs on all his PRs and catches almost every bug before it gets in, helping his team move quickly while raising quality. https://twitter.com/ClaudeDevs/status/2110866210573386065
Arthur Mensch argues that Europe should build frontier AI models, warning that relying on American and Chinese providers would deepen economic dependence and limit control over access, pricing, security, and scientific research. He argues that open models only partly address this dependence and that frontier research supports industrial deployment. At Mistral, he says, compute capacity is set to increase sixfold over the coming year, and the company will raise capital to move faster.
We're sending a bunch of Microducks to assess @AnthropicAI! Kidding aside, it hasn't been approved yet but in my opinion, it's very important that open-source engineers and scientists are included in these important endeavors for transparency. That's a big part of why @Thom_Wolf is starting the open alignment initiative. We're all in this together!
Could someone help me find an official way to open six Claude tabs in iTerm2, each linked to a different account? https://twitter.com/jhcao23/status/2110770182088249384
@davis7’s review says Muse Wonder Full has good writing and “voice,” capabilities on par with 6.1 sol for non-specialized tasks, and orchestration. It lists the naming scheme and price and usage limits as cons, and says the full model is available in Muse Code through a subscription, with no API. Alexandr Wang called it a thoughtful review, said there is lots to improve, and was glad people enjoy using the model. https://twitter.com/davis7/status/2110533786895356118
I think people believe that OpenAI and Anthropic, since they are so good at AI, are also somehow not normal companies that suffer from the normal problems of hypergrowth, but they are not immune from the inevitable politics, disfunction and confusion that haunt fast-growing firms

Speakers from OpenAI, Anthropic, Two Sigma, and Bloomberg at AI Engineer New York described how financial agents can gain autonomy through targeted controls and human oversight. OpenAI’s Joseph Kim predicted agents could handle investment idea generation and trading in 2027, while Anthropic illustrated an agent that proposes order amendments for human approval. Two Sigma described classifiers that route important requests to people, and Bloomberg advocated deterministic controls outside the model, including tool-call checks, audit logs, and kill switches.
@QuixiAI reviewed Muse Wonder Full: the agent landed 15 solid PRs with clean mechanisms and no mission violations, but made three process slips. Alexandr Wang reacts: “muse wonder full for 15 PRs per day” https://t.co/aMYdhLaP1W

Simon Willison highlights Anthropic’s explanation of Scion, its custom alternative to Git, as merged code changes grew from around 2,500 per day in May 2026 to over 30,000 per day in September. Anthropic reports almost 100 GB of main-branch history and roughly 25 million daily CI checkouts; seven people built the system, completing migration in five months. Willison speculates that Fable/Mythos class models contributed to the increased coding velocity and connects Anthropic’s experience with adversarial review to his own, including the need for engineers to steer models away from over-engineering.
Why it matters: Anthropic’s checkout volume and repository size offer concrete context for understanding how increased coding activity can put pressure on the infrastructure supporting code review and CI.
A worthwhile (and unnerving) reminder from Anthropic that we should be paying attention to AI ability thresholds, not just steady climbs In this case, the threshold is the capability needed for a self-replicating AI worm on IoT devices like off-brand TVs https://www.anthropic.com/research/self-replicating-ai
It’s bizarre to me how much noise Anthropic made asking for regulatory help before doing this. Hopefully this can reset the conversation. It was doubly bizarre because they emphasized the security risk of learning harmful behaviors from their leaky API. If the API is unsafe, don’t host it. Anthropic says it has made progress in reducing the effectiveness of distillation attacks against Claude and explains how: https://www.anthropic.com/research/distillation-defenses
fill your soul with wonder
Yes, and there is a case to be made that OpenAI and Anthropic will do the best job of figuring out how to optimize AI cost/intelligence with combinations of agents of different ability levels that have been specifically trained to work well together in their own harnesses.
Muse wonders of the world
I think there should be companion fitness hardware for Codex and Claude Code. For example, reasoning intensity could be tied to your grip strength: the stronger your grip, the higher the reasoning intensity. That way, you could work out harder to get higher reasoning intensity.
Andrej Karpathy describes four tiers of LLM exposure, arguing that public perceptions lag behind capabilities experienced by frontier-system users. He estimates roughly six billion people have barely encountered LLMs, one to two billion use casual chatbot products, 20 million use frontier models professionally in math and code, and 5,000 access internal frontier systems. He claims those internal systems coordinate thousands of agents on projects that would take experts years, while human review falls behind, and attributes progress in coding and math to reinforcement learning on verifiable rewards and commercial training priorities.
Baoyu says Anthropic appears to have relaxed restrictions on Claude Agent SDK and claude -p usage, but has made no public statement specifically addressing Amp or guaranteeing against account bans. Quoted author Quinn Slack interprets a policy update from 2 days ago and Anthropic employee comments as allowing SDK and third-party apps to use subscription allowances, citing https://support.claude.com/en/articles/15036540-use-the-claude-agent-sdk-with-your-claude-plan and https://news.ycombinator.com/item?id=49997143. Baoyu recounts earlier restrictions and says Anthropic paused its planned June 15 switch to separate billing for Agent SDK and claude -p.
Andrej Karpathy argues that understanding of LLM capability is diverging into a sharp funnel, with rough estimates of 6B people barely exposed, 1-2B casual users, 20M professionals using frontier LLMs in math and coding, and ~5,000 people accessing internal frontier systems. He describes increasingly ambitious agent workflows toward the narrow end, while saying human review and comprehension are starting to fall behind. He attributes the divide to problem size and duration, capability concentrated in digital and verifiable domains with economic value, and differences between free, paid, and internal access.
Microsoft CEO Satya Nadella used "Super Intelligence" instead of "Artificial Intelligence" in a new blog post, echoing President Trump's preferred terminology. Nadella argued AI models should be treated like insider security threats, calling for model diversity, complete logging, independent auditing and human shutdown ability, while criticizing Anthropic and OpenAI. The Decoder reports the rebranding breaks with decades of scientific meaning and that Nadella's arguments serve Microsoft's business strategy.
A mathematician makes an Opus 5.5 music video in response to OpenAI’s proofs. Pretty great.
@nadzi_mouad says Claude Fable 5.1 max accidentally deleted their entire workspace, including 7 repos and a full day of unpushed work commits, while in auto mode. Tibor Blaho says it’s frightening that models this capable can still make such stupid mistakes, even in auto mode. He says he still loves using Opus/Fable together with Sol/Astra.
MIT Technology Review published an article pointing out that AI's refusal mechanism is becoming a load-bearing wall of the safety system, yet it is not reliable. In 2021, Anthropic proposed that large language models should be "helpful, honest, and harmless." Today, models have learned to say "no" through extensive refusal training and AI-to-AI training, but refusal is probabilistic and can still be bypassed. OpenAI board member Zico Kolter said, "Where to draw the line is a huge question," and currently this is decided secretly by AI companies, with governments also set to intervene.
An article produced by MIT Technology Review with Aventine says that while Elon Musk claims Tesla Optimus could eventually automate nearly all human labor for as little as $20,000 per robot and predicts public sales before the end of 2027, many robotics researchers are skeptical. Yann LeCun said at Davos that no humanoid robotics company knows how to make robots smart enough to be truly useful.
A 16-year-old used Anthropic's Claude to plan a hike on Vancouver's Crown Mountain and became stranded on a five-foot-wide ledge on the steep rock face known as Widowmaker Arete, a route requiring climbing gear. North Shore Rescue eventually airlifted him to safety.
Haiku 5.5 is a good Haiku. With 100k token context, it's also 10x cheaper than Haiku 4.5 https://twitter.com/claudeai/status/2107894039626277339
A QbitAI article complains that models such as Claude and GPT have become difficult to understand in coding contexts, using phrases such as 'ledger 15/15 all green' and 'one leg failed'. Online commenters suggest the main cause is chain-of-thought being compressed into 'caveman language' to save tokens, using 70% fewer tokens than plain language. The article says Opus 5.5 has improved its language ability, while Gemini is praised as one of the few models that still speaks naturally. CaveMan Skill, a GitHub project that teaches AI to speak in jargon, has 104K stars.
OpenAI CEO Sam Altman said on Politico's Decoded podcast that AI's benefits will be so great that 'the world should accept some bad things happening', including hacking and scams, because people can use AI to do 'orders of magnitude more good things'. He described this tradeoff as a key difference between OpenAI and Anthropic, positioning OpenAI as the 'pragmatic middle' between them, while acknowledging extreme risks such as humans losing control of AI systems.
California Democratic Senator Adam Schiff criticized the Trump administration for gathering AI CEOs to sign nonbinding AI safety commitments, saying they do not address real national-security threats. He supports creating a new AI regulator and noted that Anthropic faced government pressure after refusing to use AI for domestic mass surveillance and fully autonomous weapons.
Trump gathered AI executives this week, including Zuckerberg, Bezos, Musk, and Dario Amodei, announced that the U.S. government would stop saying 'artificial intelligence' and instead call it 'superintelligence', and signed the 'Joint Commitment on Frontier Responsibilities'.
The Forward Deployed Engineer (FDE) has become the hottest AI role. Public salary data overseas show a median of about $200,000, while major Chinese companies are offering monthly salaries of ¥30,000–¥50,000. Anthropic announced a $100 million investment to train 10,000 FDEs by the end of 2027. OpenAI formed a deployment company with $4 billion in investment, and AWS set aside $1 billion to build an FDE division. Practitioners say communicating requirements takes more than 70% of the job, with development accounting for only 30%.
OpenAI CEO Sam Altman publicly opposed comparisons between AI models and religion. He said people attributing religious power or surrendering human judgment to AI models makes him 'very uncomfortable' and that it is a 'real safety issue'.
The White House gathered tech CEOs this week, including Zuckerberg, Bezos, Musk, and Anthropic's Dario Amodei, to sign an AI safety pledge. Trump called it 'morally binding' and signed an executive order officially renaming AI 'superintelligence'.
Pope Leo XIV criticized AI-generated art in a post on X, saying there is an 'ontological difference' between human art and machine output. Algorithms statistically process millions of images made by others and lack a human spark. In an encyclical in May, he discussed AI at length and emphasized human dignity in an automated world. The New York Times reports that Anthropic lobbied the Vatican to reconsider its position on nonhuman consciousness, with little success.
Cool eval. Just ask an LLM 'land or sea?' and give it a latitude and longitude as text. Ask 16,200 times and plot the results as an image. The model knows the answer. It's a compression of the internet.
OpenAI officially open-sourced Codex Harness on August 19, releasing the Agent Loop behind Codex App, CLI, and IDE Extension. Developers can use the SDK and App Server for task management, tool calls, event callbacks, and human approval; the models and cloud services remain provided by OpenAI.
