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: 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

Show HN: Simple Chrome extension to play focus musichttps://chromewebstore.google.com/detail/focus-music/bnecaegenddgoleofplogafikcdkckkmI built this because I was tired of the focus music dance—opening YouTube, fighting autoplay recommendations, getting distracted by comments.As a developer, I spend hours in deep work mode. 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

Show HN: Beauty Arena – An Elo-based experiment to measure aestheticshttps://beautyarena.vercel.appHi HN,I built Beauty Arena to solve a data problem I've always found annoying: absolute rating scales (1-10) are terrible for subjective data. They suffer from massive inflation and inconsistent user baselines (one person's 7 is another person's 5).I wanted to test if pairwise comparison (1v1) could produce a cleaner, strictly relative dataset.Instead of asking "How beautiful is this person?", the system asks a simple question: "Who do you choose?". It uses a ranking system inspired by competitive games (Elo/Glicko) under the hood. As users vote, a global ranking emerges based on win/loss ratios against others rather than accumulated points.I'm curious about the "wisdom of the crowd" limits here. Does a pairwise sort actually converge on a clear consensus, or does it cycle indefinitely due to intransitive preferences (A > B, B > C, but C > A)?I'd love feedback on the ranking methodology and the overall UI.
