AIAndrej Karpathy announced that he has joined Anthropic and is excited to return to research and development work on frontier LLMs. He said he remains passionate about education and plans to resume that work in time.

AIMichael Truell of Cursor says Composer 2.5 is a significant step up from Composer 2. He adds that this is only the start of work with SpaceXAI, with more improvements expected soon. Cursor's announcement describes the model as more intelligent, better at long-running tasks, and more reliable at complex instructions, with doubled included usage for the next week.

AIYann LeCun joins Jacob Effron on the Unsupervised Learning podcast to discuss limitations of LLMs and a path forward for robotics. The conversation covers his reasons for leaving Meta, his disagreements with Geoff Hinton and Yoshua Bengio, his predictions for 2027, and his new company AMI and its bet on world models.

AIAmazon has rolled out Alexa for Shopping to all customers, combining its Rufus and Alexa+ assistants into a single AI shopping tool. The assistant remembers users' preferences, past purchases, and conversations, and carries that context across phones, laptops, and Echo devices.

AIThinking Machines says its team produced 12 versions, plus many subversions, and filled 137 pages of training run logs in recent months. The post credits human-human collaboration with improving human-AI collaboration. The linked blog describes an AI designed to talk, listen, watch, and think with people in real time.

AIJan Leike has stepped away from running alignment at Anthropic to focus on other work. Ethan Perez and Sam Bowman (@sprice354_) are now leading the team, which Leike says he is confident they will do well.

AIOpenAI reports that its automated system found accidental chain-of-thought grading in RL runs for several released models, including GPT-5.4 Thinking and GPT-5.4 mini. Its analysis found no clear reduction in CoT monitorability, though the company says subtler effects cannot be ruled out. OpenAI says it still avoids grading CoTs during RL and has fixed the affected reward pathways.

Why it matters: The post shows how accidental chain-of-thought grading was detected and tested, giving a concrete method for checking monitorability risks in RL training.

AIAnthropic announced a partnership with SpaceX that will give it more compute, according to the post. The related Claude post says Claude Code's 5-hour rate limits are doubled for Pro, Max, and Team plans, peak-hour reductions are removed for Pro and Max, and Opus API rate limits are substantially raised.

AIOpenAI's Nick Turley reports that usage of the new ChatGPT images feature rose more than 50% within a few weeks. Nearly 60% of daily users are newly logged-in users, and the feature is being used across home design, learning, work graphics, and creative projects.

AIMark Chen says GPT-5.5 performs similarly to Mythos on UK AISI's cyber range, which tests long-horizon, agentic capability, and calls it one eval rather than a full picture. He adds that frontier model risks are real and that OpenAI aims to deploy AI people can actually use through mitigations. The attached chart shows completed steps per cumulative token spent for GPT-5.5, Mythos Preview, and several Claude and GPT models, from M1 reconnaissance up to M9 full network takeover.

AICognition has opened its Asia-Pacific headquarters in Singapore to expand its autonomous software engineering platform, Devin, across the region. The company says OCBC saw up to 30% improvement in code and test case generation, and its system integration test first-pass rate rose from below 50% to over 80% after deployment. Cognition is building its Singapore team across engineering, go-to-market, and partnerships, with Richard Spence leading APAC.

AIMercedes-Benz is deploying Cognition's Devin and Windsurf across its global engineering teams, from the United States to Europe and Asia. In a four-week pilot, Devin analyzed over 200,000 lines of COBOL code and cut modernization time from an estimated eight months to eight days. The company is now rolling out the full suite, with Windsurf for development, Devin as an autonomous cloud agent, and Devin for Terminal for the most complex tasks.

AIAndy Jassy announced that OpenAI's models will become available directly to customers on Amazon Bedrock in the coming weeks. The availability will be alongside the upcoming Stateful Runtime Environment, giving builders more model choice. More details are expected at the AWS event in San Francisco tomorrow.

AIMeta has committed to tens of millions of AWS Graviton cores, according to Andy Jassy, Amazon's CEO. Jassy argues agentic AI is becoming as much a CPU story as a GPU story, since multi-step orchestration and real-time reasoning are CPU-intensive. He says the Graviton5 instances deliver up to 33% lower latency between cores.

AIChip Huyen congratulated Alec Radford, Luke Metz, and Soumith Chintala on winning an ICLR Test of Time award for work published at ICLR 2016. She highlighted that the team's paper was produced by researchers in their twenties without any PhDs among them, and expressed hope that the three collaborate again.

AIOpenAI announced two health-focused launches: ChatGPT for Clinicians, a free version of ChatGPT designed for clinical work, and HealthBench Professional, a new benchmark for evaluating real clinician chat tasks. The author, Fidji Simo, wrote that she is excited about what these launches can unlock for care.

AIOpenAI researcher Mark Chen commented that Greg Brockman is doing a phenomenal job. The remark responds to a podcast interview by Ashlee Vance, who said Brockman is back in a major way setting OpenAI's strategy.

AIAnthropic says three changes to Claude Code, the Claude Agent SDK, and Claude Cowork caused recent quality complaints, and the API was not affected. The fixes were resolved by April 20 (v2.1.116), and the company is resetting usage limits for all subscribers as of April 23.

Why it matters: The postmortem traces three separate changes to specific dates and versions, showing how a bug in context management can look like broad degradation to users.

AICursor's Michael Truell says the company is partnering with the SpaceX team to scale up Composer, calling it a meaningful step toward building the best place to code with AI. The quoted SpaceX post says Cursor gives SpaceX the right to acquire Cursor later this year for $60 billion, or pay $10 billion for the work together. It also cites SpaceX's Colossus training supercomputer, described as a million H100-equivalent system, as a source of training capacity.

AIOpenAI's Mark Chen rejected the claim that science is no longer a priority, saying AI should accelerate discovery in partnership with scientists. He said Sébastien Bubeck and Helkky are taking on this mandate, which the quoted post frames as a response to reports that OpenAI's VP of Science is leaving.

AINVIDIA highlighted the developers who won the Cosmos Cookoff and how they used Cosmos Reason 2 to build projects spanning disaster-response drones, explainable visual AI, and intelligent security systems. The post links to a YouTube showcase and a LinkedIn recap of the event.

AIDevin is retiring its Core and Team plans for a new lineup of Free, Pro at $20/month, Max at $200/month, Teams with usage-based billing and an $80/month minimum, and custom-priced Enterprise. Ask Devin's Deep Mode, Devin Review after a 2-week free trial, and higher-quality DeepWiki generation will move to usage-based billing, with DeepWiki's existing generation and open-source Devin Review remaining free. Self-serve usage beyond included quota will be billed in dollars rather than ACUs.

AIThinking Machines has welcomed Luke Drago and @LRudL_, who co-founded Workshop Labs to build AI that keeps humans relevant. Mira Murati says they will continue that mission at Thinking Machines, which builds powerful AI systems that think alongside humans and extend human agency. She ties the hire to the company's broader work, including Tinker, research grants, and advancing the frontier.

AICognition is expanding into Japan, its first step into Asia, and has appointed Takumi Masai as Japan President and General Manager to lead a local team working with Japanese enterprises. DeNA has used Devin to more than double operational efficiency across multiple engineering functions, and Mizuho Securities has deployed it as one of the first large-scale financial institutions in Japan.

AIAnthropic's Sam Bowman shared a link to a system card for Claude Mythos Preview. The post itself gives no further details about the model's capabilities, benchmarks, or availability.

AIAnthropic is not releasing Mythos Preview to general availability. Instead, it is giving defenders early, controlled access so they can find and patch vulnerabilities before Mythos-class models spread across the ecosystem.

AIDario Amodei says the company has tracked growing cyber capabilities in AI models for years, which arise from their general coding proficiency. He states that the new model, Mythos Preview, represents a particularly large step up in those capabilities.

AIDario Amodei said many of the world's leading companies have joined Project Glasswing, an effort to address cyber threats posed by increasingly capable AI systems. The initiative was introduced by Anthropic and is powered by its newest frontier model, Claude Mythos Preview, which the quoted post says can find software vulnerabilities better than all but the most skilled humans.

Why it matters: The post gives a concrete example of how a frontier AI lab is organizing industry partners around AI-driven software vulnerability discovery.

AIUber is running its ride and delivery matching on AWS Graviton4 chips and training its AI models on Trainium3, according to Amazon CEO Andy Jassy. Jassy says the Graviton4 setup matches riders with drivers in fractions of a second at lower cost, while Trainium3 helps make rides smarter over time.

AIOpenAI announced applications for its Safety Fellowship, a pilot program supporting external researchers, engineers, and practitioners in safety and alignment research on advanced AI systems. The program runs from September 14, 2026 through February 5, 2027, with a monthly stipend, compute support, API credits, and mentorship, and fellows are expected to produce a substantial output such as a paper, benchmark, or dataset. Applications close May 3, and successful applicants will be notified by July 25.

AIAWS has introduced the AWS Sustainability console, which puts emissions data in the hands of users without exposing billing data. The post frames carbon and cost as similar signals that must be measured to be optimized. It links to AWS's announcement covering programmatic access, configurable CSV reports, and Scope 1–3 reporting in one place.

AICursor cloud agents produced over a million commits over the past two weeks, according to Michael Truell. He said these commits were essentially all AI-generated, with little human intervention needed since the agents run code on their own computers.

AIAman Sanger says Cursor's team evaluated many base models on perplexity-based evals and found Kimi k2.5 the strongest. Composer 2 was then built with continued pretraining and a 4x scale-up of high-compute RL, with Fireworks providing inference and RL samplers. The author admits Cursor should have named the Kimi base in its launch blog and says it will do so for the next model.

AIAman Sanger of Cursor says Composer 2 is a really good model and he is excited for more people to try it. The quoted reply from Lee Robinson says Composer 2 started from an open-source base, with only about one-quarter of the final model's compute coming from that base. Cursor plans full pretraining in the future and says it is following the license through its inference partner terms.

AILilian Weng says she is building technologies for better human-AI collaboration on next-generation hardware at scale. The post links to a Thinking Machines announcement of a partnership with Nvidia to power frontier model training and customizable AI platforms.

AIThinking Machines Lab, led by Mira Murati, has partnered with Nvidia to deploy at least 1GW of Vera Rubin systems. The stated goal is to bring adaptable collaborative AI to everyone.

AIChris Olah, a researcher at Anthropic, shares a Just Security article analyzing the designation of Anthropic as a supply chain risk. The post is brief and links to the article, which is written by a former National Security Council counsel.

AIChris Olah, whose account is owned by Anthropic, replied to Charlie Bullock, referencing GW Law professor Jessica Tillipman's view that AI companies can restrict government use of their technology. Tillipman says whether and how such restrictions apply depends on the acquisition pathway, contract type, and terms, and she has published an explainer on AI company rights in government contracts.

AIGeorgetown law professor Mark Zhia predicts a court would likely find the government's treatment of Anthropic arbitrary and capricious under the APA. He argues OpenAI and Anthropic pose similar security risks, yet the government immediately contracted with OpenAI while treating Anthropic worse than Chinese AI firms.

AIAnthropic's Chris Olah posted "Standing by our values," linking to the company's statement on comments from Secretary of War Pete Hegseth. The post itself gives no further details about the comments or the company's position.
