The Gemini AI Studio "Context Tax": How a 10-word prompt cost me £121https://news.ycombinator.com/item?id=46440008I’ve been utilizing Google’s Gemini 1.5 Pro via the AI Studio front-end to develop a new platform. The 1M+ context window is, technically speaking, a game-changer for "stitching" together a 55,000-line codebase. However, I recently discovered a predatory billing architecture that I’m calling the "Context Tax."If you use the AI Studio UI, you might be walking into a massive bill without a single warning.Here is how it happened, and the UK/EU privacy "pro-tip" I found in the fine print.In AI Studio, you start on the Free Tier. You upload your codebase (say, 700k tokens) and work for free until you hit the daily quota. At that point, the UI suggests adding an API key to "continue the conversation."The Trap: Most users (myself included) assume that after adding the key, they will be billed for incremental usage (the 10-100 tokens they just typed).The Reality: The AI Studio UI does not use Context Caching by default. Instead, it re-submits the entire 700k token history for every single "tur

Show HN: I built my own Metronome Desktop Apphttps://shredono.me/Title says all. I kept searching for a Metronome app that would have everything I need as I learn to play faster on guitar and just couldn't find one so I just built my own instead. Sharing with everyone else in case they have a need for something like this :)Has a few cool nifty features like:* Keybinds for everything. I hate my mouse* Progressive mode where the bpm increases every x bars by y bpm* Speed burst training switches between 2 speeds either at a preset amount of bars or by pressing a key

Show HN: SU_N an Adaptive Mesh Refinement Enginehttps://github.com/colinstanfordjones/SU_NMaybe somebody out here has a need for this. It features:Linear octree storage with Norton ordered blocks! It's kinda like p4est. It even has runtime partitioning! It has an MPI backend! Turn that "home lab" into a "HPC". It supports gauge lattices! Model a nuke! In zig! Does it work? Download and find out!Tests and benchmarks will show you how to make a kernel, API usage, and some examples for running a model.

Ask HN: My multi-agent financial sentiment architecturehttps://news.ycombinator.com/item?id=46437194Hello HN,I’m a college student building a financial intelligence terminal for personal use. The goal is to capture "whisper numbers" and sentiment shifts in social media before they hit mainstream headlines.I would love your feedback on the architecture and logic.The Stack:Backend: Python (PM2 managed)LLM: OpenAI GPT 5.2 for high level analysis + GPT-5-mini for news filter and market data collection (via API)Frontend: Next.js + Tailwind + RechartsThe Architecture (The interesting part):1. The CollectorInstead of hitting the LLM immediately, I run a raw scraper every 30 minutes targeting:- Nitter instances (for Twitter/X data without API limits).- GNews RSS (for official headlines).- DuckDuckGo (for general forum chatter).- 1-min OHLC Data (via yfinance) to monitor price micro-structure.2.

Tell HN: I write and ship code ~20–50x faster than I did 5 years agohttps://news.ycombinator.com/item?id=46436872I’ve been meaning to write this up because it’s been surprisingly repeatable, and I wish someone had described it to me earlier.Over the last year or so, my development speed relative to my own baseline from ~2019 is easily 20x, sometimes more. Not because I type faster, or because I cut corners, but because I changed how I use AI.The short version: I don’t use AI inside my editor. I use two AIs in parallel, in the browser, with full context.Here’s the setup.I keep two tabs open:One AI that acts as a “builder”. It gets a lot of context and does the heavy lifting.One AI that acts as a reviewer. It only sees diffs and tries to find mistakes.That’s it. No plugins, no special tooling. Just browser tabs and a terminal.The important part is context. Instead of asking for snippets, I paste entire files or modules and explain the goal. I ask the AI to explain the approach first, including tradeoffs, before it writes code. That forces me to stay in control of architecture instead of accepting a

Show HN: A Multi-agent system where LLMs challenge each other's answershttps://news.ycombinator.com/item?id=46435835Hey HN,I've been experimenting with forcing multiple LLMs to critique each other before producing a final answer.In practice, I kept working around single-model limitations by opening multiple tabs, pasting the same question into different models, comparing responses, and then manually challenging each model with the others' arguments. (Maybe some of you can relate.) It worked sometimes, but it was cumbersome, slow, and hard to do systematically and efficiently.Based on my own experiments, a few things seem to drive why different models arrive at different responses: they have different guardrails, different tendencies encoded in their weights, and different training data. And the biggest kicker of all: they still hallucinate. The question I wanted to test was whether making those differences explicit, rather than relying on one model to self-correct could reduce blind spots and improve the overall quality of the answer.So I built Consilium9.The problem: When a single LLM answers a con

I wanted something that just works: one click, instant focus music with actual binaural beats (not just labeled that way).I'd love your feedback: Which genre do you reach for when you need to focus? Any features you'd want to see added?

Ask HN:https://news.ycombinator.com/item?id=46432082I’m 17, living in Turkey, living independently, kinda graduated early through dropping out and fully responsible for my own survival right now. I left a family situation that was not safe, and since then I’ve been building my life from scratch. No financial backing, no cushion. What I’m doing at the moment: * I’m raising a small talent round (~$20k) to buy runway while I build my first company. * The round is not tied to one product yet,it’s a bet on trajectory, capability, and execution rather than a pitch for a single idea. * Investors can choose between equity in my first company or structured cash payback with interest. At the same time, I’m actively looking for cash flow through work: * Strategy, research, writing, operations, early stage problem solving * Anything where thinking clearly, moving fast, and taking responsibility actually matters * Remote or project based is ideal, but I’m flexible People around me often call what I’m doing “brave.” I don’t really experience it that

Thanks for all the thoughtful discussions; I’ve learned a lot just by reading.

Proton/electron mass ratio pure geometry – 10⁻¹³% error, zero free parametershttps://news.ycombinator.com/item?id=46430060I've spent 20 years on this and I think I finally have something. The proton/electron mass ratio (1836.152...) isn't a free parameter. It's geometry: k = log₂(reduced_Compton_wavelength / Planck_length)k_proton = 63.496 k_electron = 74.339mass_ratio = 2^(k_electron - k_proton) = 2^10.843 = 1836.1526734400 experimental = 1836.1526734400 error = 2.6 × 10⁻¹³ % That's it. No fitting. No parameters. The ratio of any two particle masses is just 2^Δk. The framework (I call it LFM) is built on 4 axioms and 1 scaling law:P_k = P₀ × 4^(-k) L_k = L_p × 2^k Anchored at k=66 (nuclear scale)Everything derives from this. Mass hierarchies, the 200× pressure differential in hadrons, material properties. I built a materials simulator using these principles: https://github.com/KeithLuton/LFM-Resonant-materials-lab The Python proof is 10 lines. Run it yourself. I'm an independent researcher (read: broke, facing foreclosure). But the math is the math. Either I'm wrong and someone can show me where, or this
