New top story on Hacker News: Claude Code weekly rate limits

Claude Code weekly rate limits 87 by thebestmoshe | 149 comments on Hacker News. Hi there, Next month, we're introducing new weekly rate limits for Claude subscribers, affecting less than 5% of users based on current usage patterns. Claude Code, especially as part of our subscription bundle, has seen unprecedented growth. At the same time, we’ve identified policy violations like account sharing and reselling access—and advanced usage patterns like running Claude 24/7 in the background—that are impacting system capacity for all. Our new rate limits address these issues and provide a more equitable experience for all users. What’s changing: Starting August 28, we're introducing weekly usage limits alongside our existing 5-hour limits: Current: Usage limit that resets every 5 hours (no change) New: Overall weekly limit that resets every 7 days New: Claude Opus 4 weekly limit that resets every 7 days As we learn more about how developers use Claude Code, we may adjust usage limi...

New top story on Hacker News: Show HN: RULER – Easily apply RL to any agent

Show HN: RULER – Easily apply RL to any agent 10 by kcorbitt | 0 comments on Hacker News. Hey HN, Kyle here, one of the co-founders of OpenPipe. Reinforcement learning is one of the best techniques for making agents more reliable, and has been widely adopted by frontier labs. However, adoption in the outside community has been slow because it's so hard to implement. One of the biggest challenges when adapting RL to a new task is the need for a task-specific "reward function" (way of measuring success). This is often difficult to define, and requires either high-quality labeled data and/or significant domain expertise to generate. RULER is a drop-in reward function that works across different tasks without any of that complexity. It works by showing N trajectories to an LLM judge and asking it to rank them relative to each other. This sidesteps the calibration issues that plague most LLM-as-judge approaches. Combined with GRPO (which only cares about relative scores wit...

New top story on Hacker News: Show HN: I Got Tired of Calculator Sites, So I Built My Own

Show HN: I Got Tired of Calculator Sites, So I Built My Own 23 by calculatehow | 13 comments on Hacker News. I’ve always found that online calculators tend to have bad UIs, especially on mobile. Most of the calculator websites I’ve come across use outdated and inconvenient ways of inputting data, or they format the results in confusing ways. I’ve noticed that fraction calculators (especially mixed fractions) are terrible to use, even on desktop. I haven’t built one of those yet, but it’s something I’m planning to tackle soon. This is a project I’ve always wanted to work on, but I’m relatively new to this space. So far, I’ve created a collection of simple calculators focused on math and finance. I’d really appreciate any feedback on the UI/UX or anything else you think could be improved. You can try it here: https://ift.tt/DYHSO5i
