{"slug": "agentic-coding-outperforms-human", "title": "Agentic Coding Outperforms Human", "summary": "A developer spent an hour trying to optimize a Rust function but failed, then used a local LLM agent (Qwen 3.6 35B) in OpenCode to suggest and implement a faster, clearer solution. The LLM's alternative approach outperformed the developer's manual effort, highlighting how AI agents can overcome human cognitive biases like sunk-cost fallacy.", "body_md": "I spent an hour trying to **improve** a **function** in my **Rust program**. Unfortunately, after all my work, it turned out my changes made it slower, so I had to discard the new version. In dismay, I loaded a local LLM in OpenCode (Qwen 3.6 35B with AutoRound) and asked it for some tips.\n\nIt came up with an idea I had not considered—split the function in **two parts** and remove a bunch of `if`\n\n-statements. I had the LLM agent implement the code, and after benchmarking, I found the **new version** was **faster**. I spent some time tidying things up, and now the program is faster and clearer than before.\n\nInterestingly, it seems that:\n\n• My own coding failed as I tended to be reluctant to give up on a failed approach I had invested time in.\n\n• The LLM came up with a completely different idea and implemented it.\n\n• In this particular case, the LLM agent seems to have outperformed me.\n\nI don't think this is proof that the LLM is a **better programmer** than I am. It does seem to indicate I tend to get stuck on trying to force a bad solution to work. Having a different approach altogether worked better in this case.", "url": "https://wpnews.pro/news/agentic-coding-outperforms-human", "canonical_source": "https://www.dotnetperls.com/2026_6_24_agentic-coding-outperforms-human", "published_at": "2026-06-24 07:00:00+00:00", "updated_at": "2026-07-20 15:28:10.007145+00:00", "lang": "en", "topics": ["large-language-models", "ai-agents", "developer-tools"], "entities": ["OpenCode", "Qwen 3.6 35B"], "alternates": {"html": "https://wpnews.pro/news/agentic-coding-outperforms-human", "markdown": "https://wpnews.pro/news/agentic-coding-outperforms-human.md", "text": "https://wpnews.pro/news/agentic-coding-outperforms-human.txt", "jsonld": "https://wpnews.pro/news/agentic-coding-outperforms-human.jsonld"}}
