Hey HN, we built an Econ+Finance database to let AI agents do investment research. We spend a lot of tokens to organize macro releases and SEC filings into a clean format, so that your agents have more context to do actual analysis. The problem AI agents are great at data analysis. But they become ineffective if most of their context window is spent on gathering and cleaning data, instead of validating hypotheses. Data in the wild is messy and rarely standardized.

<p>You asked your AI to help you plan a trip.

What you got was a thoughtful non-answer dressed up as advice.</p> <p>That gap — between what AI <em>tells</em> you and what it could actually <em>do</em> for you — is the gap agentic AI is designed to close.

You write normal Chat SDK handler code, and calling send inside a handler hands the message to your agent. Register handlers on bot exactly as you would in a standalone Chat SDK app. Out of the box, the channel: Mounts a webhook route for each adapter (e.g., /eve/v1/chat/slack ) Shows a typing indicator

Grok 4.5 from SpaceXAI is now available on AI Gateway . Built for coding, knowledge work, and STEM, the model accepts text and image inputs. Grok 4.5 supports low, medium, and high reasoning levels and defaults to high. Set the level with reasoning to balance speed against depth. To use Grok 4.5, set model to xai/grok-4.5 in the AI SDK : AI Gateway provides a unified API for calling models, tracking usage and cost, and configuring retries, failover, and performance optimizations for higher-than-

<p>Everyone knows Next.js is the default full-stack JavaScript framework in 2026. The job ads say so, the AI tooling assumes so, the conference talks revolve around React Server Components, and even people who've never touched a Vue file have an opinion about which version of <code>getServerSideProps</code> they like best. Everyone is mostly right - and missing a piece of the story.</p> <p>The piece they're missing is that on the other side of the framework wall, Nuxt has spent the last two year

I've seen numbers like 75% of code at Google is AI generated, huge %s of code overall is AI generated, open source projects overwhelmed with "slop" PR requests. It's pretty undeniable that AI code is here to stay - so on your teams / companies how are you managing staying up on PR reviews, and documentation?
