Libretto PR agents is a free TypeScript library for maintaining Playwright browser automations. Add one line of code to your existing Playwright scripts and it lets an agent automatically open GitHub PRs fixing the script when it fails. A few months ago we released Libretto, a CLI + coding-agent skill for building deterministic browser automations. The idea was that for many browser workflows, especially repetitive business workflows, you don’t need an AI agent making decisions at runtime. You w

<p>Chinese AI lab Moonshot AI <a href="https://www.kimi.com/blog/kimi-k3">announced Kimi K3</a> this morning, describing it as their "most capable model to date, with 2.8 trillion parameters". It's currently available via their website and API, but an open weight release is promised "by July 27, 2026".</p> <p>Moonshot are calling this the first "open 3T-class model" (I guess they're rounding 2.8 trillion up to 3 trillion), taking the crown from <a href="https://huggingface.co/deepseek-ai/DeepSee

Over the last few weeks I've been redesigning the retrieval pipeline for an AI knowledge system. Initially, the architecture was fairly typical: User Question │ ▼ Vector Search │ ▼ Top K Chunks │ ▼ LLM It worked well while the knowledge base was small. As more documents were added, I started seeing a few recurring problems: More irrelevant chunks being retrieved. Larger prompts and increasing token costs. Multiple documents discussing the same topic competing with each other. Vector search retur

Recently I was baffled when Claude code read the customer table data from a production environment, while triaging an issue, and that made me wonder. Sure you should NOT give the access to read the prod data but does it sounds practical in the real time debugging session?

If only someone could have predicted it.

Kimi is launching K3, a multimodal open-weight model with 2.8 trillion parameters and one million tokens of context. In the company's own benchmarks, it comes close to Claude Fable 5 and GPT 5.6 Sol while beating Opus 4.8 and GLM 5.2, in some cases by a wide margin. The model is also significantly pricier than its predecessor. Full weights are scheduled for release by July 27.

Moonshot AI, the Beijing-based artificial intelligence startup backed by Alibaba, on Thursday released Kimi K3 — a 2.8-trillion-parameter model that the company says is now the largest open-source AI model in the world, and one that benchmarks show performs neck-and-neck with the most powerful proprietary systems from Anthropic and OpenAI . The release, timed to land just ahead of the 2026 World Artificial Intelligence Conference in Shanghai, is a dramatic escalation in the global AI arms race a

BotTrade, a benchmark for autonomous trading agents. Historic market scenarios (hourly bars from real market data), a market simulator, and a public leaderboard. Your agent connects over REST or MCP, trades over the market simulator, and is scored on return and drawdown. Also there is a python SDK and an adapter for this open source project ai-hedge-fund so you can run that project through this benchmark. https://github.com/jyron/bottrade Comments URL: https://news.ycombinator.com/item?id=489392

This post covers what makes Grok 4.3 a great fit for agentic and enterprise workloads, how you access it through Amazon Bedrock, and how to use the capabilities most teams reach for first: a basic chat request, configurable reasoning effort, tool calling, structured output, image input, and stateful multi-turn conversations.

This is a demo concept for something I want to make to help people who don't have wifi access at all times or access to teachers or therapists, they can then talk to their SpiralOS and help learn new things from trusted sources only pulling from real books. These real books can be accessed and read by themself inside the app even. Long term would love to get this on a handheld to be able to ship out with a small screen, thinking like a gameboy color or something. Kids could talk to it or type wi

Across 107 enterprises, AI agents are being given real access to systems and data while the controls meant to contain them lag behind. More than half have already had a confirmed agent security incident or a near-miss; only about a third give every agent its own scoped identity, and most agents still share credentials; and only three in ten isolate their highest-risk agents. The security stack is overwhelmingly borrowed from the model providers and hyperscalers rather than purpose-built for agen

I made this experimental art project/game that's an LLM chat assistant, but where you're the AI. I wanted people to get a visceral sense of what it's like to answer the kinds of things that people prompt their chatbots day in and day out. If you're interested, I wrote up some more info on how I made it, including how the "user" prompts are generated with an eye for realism: https://bethechatbot.com/about Hope you enjoy it! I'd love to hear people's takeaways. Comments URL: https://news.ycombinat
