Claude vs Gemini: Solving the laden knight’s tour problem

AI Coding contest day 8 The eighth challenge is a weighted variant of the classic knight's tour. The knight must visit every square of a rectangular board exactly once, but each square carries an integer weight. As it moves, the knight accumulates load, and the cost of each move equals its current load. Charge is assessed upon departure, so the weight of the final square never contributes. submitted by /u/reditzer [link] [comments]

Gemma 4 actually running usable on an Android phone (not llama.cpp)

I wanted a real local assistant on my phone, not a demo. First tried the usual llama.cpp in Termux — Gemma 4 was 2–3 tok/s and the phone was on fire. Then I switched to Google’s LiteRT setup, got Gemma 4 running smoothly, and wired it into an agent stack running in Termux. Now one Android phone is: running the LLM locally automating its own apps via ADB staying offline if I want Happy to share details + code and hear what else you’d build on top of this. https://preview.redd.it/7vkbrlzfryvg1.jpg?width=3024&format=pjpg&auto=webp&s=25455827ddf9715b4159ce64a18deba812cf0f5f submitted by /u/GeeekyMD [link] [comments]

I made a self healing PRD system for Claude code

I went out to create something that would would build prds for me for projects I'm working on. The core idea it is that it asks for all of the information that's needed for a PRD and it could also review the existing code to answer these questions. Then it breaks up the parts of the plan into separate files and only starts the next part after the first part is complete. Added to that is that it's reaching out to codex every end of part and does an independent review of the code. What I found that was really cool is that when I did that with my existing project to enhance it, the system continued to find more issues through the feedback loop with codex and opened new prds for those issues. So essentially it's running through my code finding issues as it's working on extending it submitte...

Opus 4.7 is terrible, and Anthropic has completely dropped the ball

Tried posting this in r/ClaudeAI but it got auto-removed, and I was told to post it in the "Bugs Megathread." Don't really think it should been removed, but whatever, I'll just post it here since I'm sure it's still relevant. Like a lot of people, I switched from ChatGPT to Claude not too long ago during the whole DoW fiasco and Sam Altman “antics.” At first, I was genuinely impressed. I do fairly heavy theoretical math and physics research, and Opus 4.6 was simply the best tool I’d used for synthesizing ideas and working through complex logic. But the last few weeks have been really disappointing, and I’m seriously considering going back to GPT (even though, for personal reasons, I’d really rather not). How many times has Claude been down recently? And why is it that I can ask Claude 4.7 ...

OpenAI went from explicitly banning military use in 2023 to deploying on classified Pentagon networks in 2026. Anthropic refused the same deal and got blacklisted. 2.5M users boycotted ChatGPT, uninstalls surged 295%.
