Claude in Chrome went GA with auto-approve on by default. Anthropic published the classifier's miss rate. It isn't the number in the press coverage.
I gave the models I actually use the same four design briefs and published every result. There's no single best LLM for frontend design, and here's why.
Qwen3.8-27B runs on consumer hardware under Apache 2.0. I tested it on a 24GB M4 — here's the real RAM, speed and privacy picture, minus the hype.
I ran Claude Opus 5, GPT-5.6 Sol and Grok 4.5 through four hard builds: gallery site, spreadsheet app, image codec, repo audit. Times, results, verdict.
I ran Alibaba's new 2.4T Qwen3.8-Max-Preview through 4 real coding tests. Results rival Fable 5 and Grok 4.5 — with one big catch: speed.
I ran Grok 4.5 through my usual coding tests — website builds, a Go poker sim, a site audit. It's fast, cheap, and it found a bug no other model caught.
I tested Microsoft's MAI-Code-1-Flash coding model on real projects. Fast and cheap, yes, but here's why I won't be switching from Kimi K2.7 Code.
