AICognition raised over $1B at a $26B valuation, led by Lux Capital, General Catalyst, and 8VC. Enterprise Devin usage grew more than 10x since the start of this year, and run-rate revenue reached $492M. The company also said it launched SWE-1.6, which reaches up to 950 tok/s and has become the most used model in Devin Desktop.
AIAmazon CEO Andy Jassy joined Amazon teammates to prep meals at Community Lunch on Capitol Hill in Seattle during Global Month of Volunteering in May. The nonprofit serves free, made-from-scratch meals to 200-300 low-income and unhoused neighbors each weekday, and nearly 2,000 Amazonians have volunteered there since 2023. Amazonians completed more than 500,000 volunteer activities across 55 countries last year.
AIBenedict Evans argues that predicting AI's job impact by occupation is mostly impossible, citing accountants: despite a century of accounting automation from calculators to spreadsheets and ERP systems, the number of accountants kept rising. He says job titles and business models change over time, so exposure scores based on census categories can mislead.
AIAn OpenAI model disproved Erdős's longstanding planar unit distance conjecture, which Paul Erdős posed in 1946, by discovering a new family of constructions that performs better than the square grids mathematicians had long assumed. Mark Chen says the proof draws on algebraic number theory and describes it as the first time AI has autonomously solved a prominent open problem central to a field of mathematics.
Why it matters: The post names the specific open problem and the approach used, giving readers a concrete case of AI producing a research proof in mathematics.
AISolving it takes a community, join us.
AII think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.
AIThis is the very start of our work with SpaceXAI. Hope to have more improvements out soon.
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.
AIWe’re looking for supercomputing engineers to build the infrastructure behind real-time interactive models, Tinker, and large-scale training: scheduling, storage, networking, reliability, and distributed systems at scale. Hiring in NYC and SF
AI…log book. Turns out human-human collaboration is important to improving human-AI collaboration. 😊
AII still remember when that company was nothing more than an idea. Proud of @MichaBreakstone and proud to be an advisor to this mission-driven team.
AIWe’re proud to build together with the RAGFlow team through deep PaddleOCR integration and document AI collaboration. More to come! 🌊
AIVery excited about this! Many things are needed to make AGI go well, and alignment is only one of them. More on this soon…
AIEthanJPerez and @sprice354_ are leading the team going forward, and I’m confident they’ll do an amazing job.
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.
AIUsage up >50% in just a few weeks + nearly 60% of daily users coming from newly logged-in users. Incredible breadth of utility across home design, learning, work graphics, creative etc
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.
AIHuge congratulations to all the teams across @Google working hard to turn AI breakthroughs into everyday reality for our users! ✨ #TIME100Companies
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.
AIWe’re excited to make OpenAI's models available directly to customers on Bedrock in the coming weeks, alongside the upcoming Stateful Runtime Environment. With this, builders will have even more choice to pick the right model for the right job. More details at our AWS event in San Francisco tomorrow.
AIAnthro probably needs to scale up Account Support via Claude or via humans (traditional account managers). Would be funny if they chose humans. Alternatively, more and more companies can probably go multi-AI with open harnesses. Similar problems to the cloud era enterprise pains. I'm sure these issues would apply to all the other AI providers.
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.

AIIt's really cool to see work produced by a group of 20-somethings without a single PhD between them winning this award. I hope to see these three collaborate again one day :)
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.
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.
AIThey have to be extreme co-design companies (like Nvidia, but even more). That’s where the global minima are. I’m especially thinking about Apple and how with the recent transition a lot of people are saying it’s a hardware company. It should be (and hopefully will be) extreme co-design.
AIThe future can’t be about dumping results on the community en masse. We need to work with scientists to use AI to accelerate discovery without stripping away the artistry. Excited for @SebastienBubeck and @ahelkky (who are both amazing scientists) to take on this mandate!

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.
