Railway, a San Francisco-based cloud platform that has quietly amassed two million developers without spending a dollar on marketing, announced Thursday that it raised $100 million in a Series B funding round, as surging demand for artificial intelligence applications exposes the limitations of legacy cloud infrastructure. TQ Ventures led the round, with participation from FPV Ventures, Redpoint, and Unusual Ventures. The investment values Railway as one of the most significant infrastructure...
The artificial intelligence coding revolution comes with a catch: it's expensive. Claude Code, Anthropic's terminal-based AI agent that can write, debug, and deploy code autonomously, has captured the imagination of software developers worldwide. But its pricing — ranging from $20 to $200 per month depending on usage — has sparked a growing rebellion among the very programmers it aims to serve. Now, a free alternative is gaining traction. Goose, an open-source AI agent developed by Block (the...
Alfred Wahlforss was running out of options. His startup, Listen Labs, needed to hire over 100 engineers, but competing against Mark Zuckerberg's $100 million offers seemed impossible. So he spent $5,000 — a fifth of his marketing budget — on a billboard in San Francisco displaying what looked like gibberish: five strings of random numbers. The numbers were actually AI tokens. Decoded, they led to a coding challenge: build an algorithm to act as a digital bouncer at Berghain, the Berlin night...
D4RT: Unified, efficient 4D reconstruction and tracking up to 300x faster than prior methods.
Our latest Veo update generates lively, dynamic clips that feel natural and engaging — and supports vertical video generation.
Salesforce on Tuesday launched an entirely rebuilt version of Slackbot, the company's workplace assistant, transforming it from a simple notification tool into what executives describe as a fully powered AI agent capable of searching enterprise data, drafting documents, and taking action on behalf of employees. The new Slackbot, now generally available to Business+ and Enterprise+ customers, is Salesforce's most aggressive move yet to position Slack at the center of the emerging "agentic AI" ...
Anthropic released Cowork on Monday, a new AI agent capability that extends the power of its wildly successful Claude Code tool to non-technical users — and according to company insiders, the team built the entire feature in approximately a week and a half, largely using Claude Code itself. The launch marks a major inflection point in the race to deliver practical AI agents to mainstream users, positioning Anthropic to compete not just with OpenAI and Google in conversational AI, but with Mic...
Nous Research, the open-source artificial intelligence startup backed by crypto venture firm Paradigm, released a new competitive programming model on Monday that it says matches or exceeds several larger proprietary systems — trained in just four days using 48 of Nvidia's latest B200 graphics processors. The model, called NousCoder-14B, is another entry in a crowded field of AI coding assistants, but arrives at a particularly charged moment: Claude Code, the agentic programming tool from riv...
When the creator of the world's most advanced coding agent speaks, Silicon Valley doesn't just listen — it takes notes. For the past week, the engineering community has been dissecting a thread on X from Boris Cherny, the creator and head of Claude Code at Anthropic. What began as a casual sharing of his personal terminal setup has spiraled into a viral manifesto on the future of software development, with industry insiders calling it a watershed moment for the startup. "If you're not readin...

People keep taking influencer posts about papers at face value. Serious accounts are now quoting them. Just paste the post and the link to the article into any frontier model and ask if the post is supported by the evidence in the piece.
Incredible news coming for NVIDIA GTC next week. Would really tune in for the Jensen keynote on the future of agent inference. Got excited for some incredible developments in AI inference.
I will be in New York this week. Looking forward to seeing friends old and new. We are also hosting an underground salon this Tuesday to bring together friends and those shaping the next era of intelligence.
Another 15k like post that is wrong about an AI paper findings. The community note undersells how wrong: the creativity paper measured 61 people (underpowered) and found NO drop in creativity at 30 days. The ChatGPT group was actually still significantly higher at the end.
Microsoft found out how to etch 5 terabytes of data into a piece of glass and it survives for 10,000 years. Project Silica is a storage system that uses ultrafast lasers to write data directly into glass. Each laser pulse lasts one trillionth of a second.
Most companies will laugh you out of the room if you try to sell them the idea of replacing people with an unsupervised AI process.
This is essentially the workflow of coding in production on the server with Claude Code. It is instant and extremely high velocity. AI lets us dev extremely fast and the bottleneck now is slow deployments. PR review has already become a bottleneck for high output teams.
Can it run DOOM was a joke for 30 years. A petri dish full of human skin cells just said yes. Cortical Labs trained 200,000 human neurons to play the 1993 FPS game in a week.
Every 6 weeks I realize I have been substantially under-ambitious with current models and feel like an idiot. The pace of AI capability improvements keeps surprising developers.
I asked Claude to write my constitution. I thought its Amanda constitution was very touching.
Released today: /loop. A powerful new way to schedule recurring tasks, for up to 3 days at a time. Examples: babysit all PRs and auto-fix build issues, or every morning use the Slack MCP to give a summary.
You can run Qwen 3.5 on an iPhone via the Locally AI app. The 4B model is a 3.06GB download. Available in 4 sizes: 0.8B, 2B, 4B, and 9B on supported iPads. The models support vision and reasoning toggle.

Recorded what might be the single most impactful conversation about OpenAI Frontier, Symphony and Harness Engineering. Small team steering Codex opened and merged 1,500 pull requests to deliver a product used by hundreds of internal users with zero manual coding.
GPT-5.4 is great at coding, knowledge work, computer use, etc, and people are enjoying it. But it is also Sam Altman favorite model to talk to. OpenAI has missed the mark on model personality for awhile, so it feels extra good to be moving in the right direction.
