Build long-horizon agents with Grok 4.7 on Amazon Bedrock
AWS Machine Learning
Grok 4.7 is now available on Amazon Bedrock. In this post, we build a tool-calling agent on Grok 4.7 and evaluate it on three reasoning tasks at four reasoning effort levels, measuring correctness and token cost per completed task. We show how to tune the trade-off per request and monitor it in production.

Show HN: Pulse Local, a Mac budgeting app whose AI models run on your machine
Hacker News · 101 pts · 55 comments
Hi HN, I’m Niz. Pulse Local is a budgeting app for Mac (Apple Silicon, beta) that answers questions about your spending with models that run on your machine. Local mode needs no account. The ledger and your questions stay on the machine, and the app sends no analytics or crash logs. I felt there are not enough consumer apps that run locally with no calls to the outside world that help us manage sensitive corners of our lives. This app in its local variant only downloads a couple of models and occasional updates, it does not send any analytics nor data. Features-wise, Pulse local is a complete budgeting app that offers an assistant built on…
Show HN: Parsimony – an open-source benchmark for how much code AI models add
Hacker News · 66 pts · 12 comments
Existing benchmarks measure solve rate and token output/cost, but don’t punish excess code, which makes a codebase harder to work with in the long term. I wanted to measure this since it matters most for long-term projects. Method: it takes the patches that benchmarks already publish (DeepSWE, SWE-bench Verified, SWE-bench Live) and counts “coding units”: syntax elements like statements, calls, names and literals. I didn’t use lines of code, so cramming code isn’t rewarded. Deleted code is subtracted, so it measures net units. GPT-6 and Claude 5.5 have no public patches yet, so I ran them myself on 3–10 tasks on my own subscriptions (shown as…

Show HN: Wonderhop – A daily game: guess what most people say, or what none do
Show HN · 6 pts · 5 comments
Hello HN! Wonderhop is a small browser game with no account needed to play, everyday there are 4 rounds of 7 quesitons like “Name a food that a lot of people hate” The goal depends on the mode: Either gives the answer most people would give, the one no one would give, the oldest answer or the most recent one and there’s a leaderboard for the day. The most interesting part of the project was understanding answers that are typed freely and in 10 languages, there was some typos, plurals, nickname, or even duplicate way of sayign the same thing. We needed AI judge that checks it really existes conencted to some API like wikipedia to judge the…
Show HN: AI Hub – Open Access Lesson Plans for Teaching Students about AI
Show HN · 6 pts · 0 comments
The AI Hub provides 91 curated lesson plans teaching middle and high school students about AI - how it works, what the risks and benefits of AI are, and how it is impacting society. These activities come from six different nonprofit organizations that are building educational resources for classrooms. Our nonprofit worked with 16 different teachers to comb through more than 200 different resources, with the teachers vetting these resources to find the best resources for their classrooms. The end result is 91 different lesson plans and activities that cover a wide range of different topics. Schools across Pittsburgh will be using these…
