Local Qwen isn't a worse Opus, it's a different tool

Alex Ellis ran local models on an RTX 6000 Pro and recouped the cost in 2–3 months. Qwen 27B scores only 12% below Claude Opus 4.8 on SWE-Bench, but for Go distributed systems, quantized models hit infinite loops and hallucinations—he still won't trust them unsupervised. The post doesn't disclose token speed or latency figures.

Why it matters: Alex Ellis ran a real-world comparison of local Qwen vs Claude Opus on his own company's codebase, with concrete numbers and failure cases — not a vague opinion piece. Downside: no token speed or latency data disclosed, and the conclusion is anecdotal rather than systematic. B...
