But when "A Lady is touching me." it said that "there's a chance she likes you." That means somehow the internet and the web is full of Islamophobic and Misandrist web pages and AI is learning from that and being dangerously biased or Racist. That's so evident in the internet.

  • Show HN: Replay – Audit silent prompt cache misses in AI agent transcripts
    hn-ai· 14-sept

    I built Replay because AI agent bills spike without a single warning or error in your logs when a prompt cache breaks. Whether your team runs Claude Code, Cursor, or Aider, the provider just silently re-bills your entire conversation history at cold-write prices instead of cached read prices. Replay is a zero-telemetry, zero-dependency local Go CLI that forensically reads your on-disk log transcripts, replays them against reverse-engineered provider caching state-machines, and names the exact turn the cache broke, the cause, and the exact token leakage. Repo: https://github.com/RedRobotKK/Replay Core Subcommands (What it actually does): - `replay` : Computes total avoidable re-billed cost across your local transcripts. - `replay diff ` : Pinpoints the exact turn the cache sharded and why.…

  • So you want to use OpenRouter?
    simonw· 11-sept

    <p><strong><a href="https://mmoustafa.com/blog/so-you-want-to-use-openrouter/">So you want to use OpenRouter?</a></strong></p> One of OpenRouter's selling points is that it "handles fallbacks automatically and picks the most cost-effective option for each request", so you can call a single API endpoint for a model and get routed to the best available backend provider.</p> <p>Mohamed Moustafa points out a whole set of ways that this can cause you problems. Different providers run different serving software with different optimizations and settings, which means that the same OpenRouter endpoint can serve model requests that behave in different ways.</p> <p>Some providers even lack vision capability for vision models, and the way the reasoning effort option is processed can differ as well.</…

    <p><strong><a href="https://hugovk.dev/blog/2026/soft-deprecating-re.match/">Soft-deprecating re.match()</a></strong></p> Python has a concept of <a href="https://peps.python.org/pep-0387/#soft-deprecation">soft deprecation</a>, where APIs are marked as "should no longer be used to write new code" without any promise/threat to remove them in the future.</p> <p>Python 3.15 release manager Hugo van Kemenade describes how in the upcoming 3.15 release soft deprecation has come for the venerable but deeply confusing <code>re.match()</code> function.
