HN comment previews with Gemini 1.5 Flash-8B
I was inspired by the notification summaries on iOS 18 and really liked the idea of AI giving you a quick preview of the content before going to the content. I applied that to HN and built a Chrome extension that summarizes the sentiment and content of HN comments and previews it right next to the stories on the homepage. Makes it so much easier to decide whether I want to delve into the HN comments of a story. It gave me a chance to play with Gemini 1.5 Flash-8B which has been great. Super fast, super cheap, huge context and does a great john on basic tasks like summarizing comment threads.…
What it does
In the maker’s words, at launch
I was inspired by the notification summaries on iOS 18 and really liked the idea of AI giving you a quick preview of the content before going to the content. I applied that to HN and built a Chrome extension that summarizes the sentiment and content of HN comments and previews it right next to the stories on the homepage. Makes it so much easier to decide whether I want to delve into the HN comments of a story. It gave me a chance to play with Gemini 1.5 Flash-8B which has been great. Super fast, super cheap, huge context and does a great john on basic tasks like summarizing comment threads. Get it here: https://github.com/StreakYC/hn-summarizer/ You’ll also need a Gemini API key from: https://aistudio.google.com/ to make the extension work.

Hi HN, Sharing HN Insights, a webapp I built that highlights trending themes and summarizes discussion threads from the front page. This started earlier this week as a toy project to test out Gemini 3 Pro in aistudio. I found the POC useful, so I decided to productionize it. I've included the original seed prompt below: > Create an app that creates a summary of the comment threads for hacker news front page. The UX should be similar, but clicking the comments instead opens a summary. The summary is generated when clicked so it can gather new threads. To productionize, I used Claude Code and…
- HTHN top 30 summarized by Gemini 2.5 Pro2025 · tinysums.ai · ▲6
Fun little project, had Gemini 2.5 Pro summarize HN's top 30 each hour, both the stories and comment sections. Pretty impressed with Gemini 2.5. It's probably the first model other than Claude 3.7 Sonnet where I actually find the output readable. I normally use 3.7 Sonnet for coding, but used Gemini for the codegen on this one as well. Was pretty impressed! Using Cursor, it seemed to instruction-follow better than Claude generally does, and remain lucid during very long agent sessions. Thanks for your feedback!
- TATelescope, a news reader app2017 · ▲90
I got fed up with the news reader apps out there so I decided to make my own. Its a simple concept where it tracks all your favorite news sources for new posts and the social shares it received. Then it ranks it HN/Reddit style using social shares as upvotes. It's not meant to be alternative to HN, just a focused way to track your favorite sources. Please try it out and let me know what do you think, http://telescope.surf/ Note: you can do 'Add to Homescreen' on mobile to make it as an app. Please leave a feedback or any feature wishlist you may have. Thanks!

Hey HN! Thank you for all the support and feedback on my original submission 2 months ago. I've been improving the backend using a MCTS/AlphaZero approach and it's currently producing much better results. My long term goal is to allow users to manage multiple projects, deployed autonomously, both from scratch and by making continual updates all prompted with natural language. The cost of each project has been lowered to $9 as performance with smaller models has improved (I migrated from Claude-3-Opus to gemini-1.5-flash). Thanks for checking it out!

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…
