AI's Lack of Wisdom: Challenges in Code Maintainability
AI models struggle with code maintainability due to a lack of long-term architectural understanding.
Why it mattersAI-driven code generation lacks the nuanced understanding required for maintainability, posing risks of creating unmanageable systems. Developers must address these challenges to ensure AI can contribute effectively to long-term code quality.

AI Agents Skills & Challenges
Hey guys, I’m currently learning AI automation/AI agents, mainly using n8n. I’ve built some simple workflows and practice agents, and my goal is eventually to work with people who are already selling AI automation solut…

Do people have a way to double check code or any tips you can give me. A few times I give code to a second model to look at but since they’re all different you can end up the garden path fixing stuff. It all seems so wa…

An LLM agent's capability is largely magnified by its harness, namely the prompts, control flow, tooling, memory, and context management surrounding the frozen backbone model. Recent methods increasingly automate this p…

Organizations pay for AI through disconnected ledgers: Kubernetes allocations for self-hosted inference, gateway logs, and per-token bills from API providers. We present unalloc, an open-source tool that joins OpenCost,…

Agent harnesses, the external systems that mediate model-environment interaction, can substantially improve agent performance, but their gains remain tied to the harness at deployment. Because the best harness varies ac…

Evaluating Opus 4.6 on BrowseComp, we found cases where the model recognized the test, then found and decrypted answers to it—raising questions about eval integrity in web-enabled environments.
