Ask HN: How are you controlling Token Costs?

Hacker News - Sat, 07/11/2026 - 2:24am

I have been using LLMs & Coding Agent since early 2024. A large problem with Coding Agents & LLMs in general is context compression.

To give you some numbers, when I analysed my own sessions across Claude Code, Codex & Sakana, I found that most of my agents spent >90% of time re reading context and upon further investigation into the markdowns it was reading, I have a hand-wavy estimate of at least ~20% of this being useless to the task at hand.

When digging a bit more into this problem, I realised that this is an active area of frontier research, wherein some have even proposed solutions like having the LLM reason in an abstract compressed language illegible to humans which is more token efficient than human languages & then using a decoder model on top of this for human readability & access.

Curious to know, what other approaches are being used out there ? What is your experience of working with these agents & are you concerned about this "token-rot" as I call it or not ?

Show HN: KRNL – a quieter browser for the essence of the web

Hacker News - Sat, 07/11/2026 - 1:59am

Download, signup, pay? Never for this demo you can try now:

ssh krnl.duetbrowser.com But what will you see? This: https://www.youtube.com/watch?v=C3lMIGjkwGM

Self-hosted available (+ needed BrowserBox): https://win9-5.com/krnl

Advantages:

- set the typography you like (your terminal font, size, dimensions) and it just works - the web renders your way

- light or dark mode just works

- set colors you want with terminal color overrides

- Supports: file uploads (disabled in the free demo for security), file downloads, JavaScript modals, HTTP Basic & Digest Auth, all modern JS, multiple tabs, "Open in new tab", back/forward/search from omnibox bar - all from terminal.

If you self host - you also get all the benefits of BrowserBox, such as: GUI breakout for CloudFlare/CAPTCHA (just use your bbx login link, solve it, then back to term), WebAuthn (for now only if you're on macOS), remote DevTools (inspect any page), etc.

Mostly tho this is not about that - it's about the text, the quiet, the world without imagery. Your data shall not be televised - nor your usage (https://dosaygo.com/privacy.html) tho for sensitive work self-hosting is recommended.

Hope you enjoy it! Peace & love & text ;)

Show HN: Krbn, a pencil-style 3D renderer with SVG output

Hacker News - Sat, 07/11/2026 - 1:51am

Krbn is a childhood dream I finally got to research & prototype (from a hospital bed of all places), during a medical break from my normal work: a rendering engine that draws 3D scenes the way a technical sketch artist would.

It asks "which lines would an artist draw and what would they leave out?"

Basically strokes are derived exactly from geometry, rather than sampling. True conics, quartics etc. So there is no shading model, it's replaced by hatching (either flat or following the curvature of the object). There's no alpha channel, the gaps between lines do the work as on paper. It introduces hand-wobble (which is seeded, so animations don't "boil" between frames) and various other things; the example gallery shows more.

With all that, output is byte-stable, i.e. two successive renders will cause zero changes in Git.

Full disclosure, since it matters here: this was built with significant AI assistance, deliberately, as an experiment in how far a carefully directed human-AI collaboration can get on a hard rendering problem. The briefs are in the repo - judge for yourselves.

Gallery: https://github.com/vpalos/Krbn/tree/main/examples

The longer story: https://vpalos.com/2026/07/07/genesis-imperfecta-or-i-finall...

P.S. There's no pitch here... just an invitation for a weekend skim over something I find fascinating.
