Large Language Models (LLM) & AI Market: Review: Claude Opus 5 Wins; AI Browser Use & Raspberry Pi Projects
This newsletter episode reviews AI workflows and a blind benchmark in which Claude Opus 5 finished first among seven models. It describes practical browser-control use cases (Codex) for QA, LinkedIn triage, and remote phone operations; a maker story where Cursor plus a Raspberry Pi enabled non-programmers to build hardware projects; and observations about model personality, compute-effort tradeoffs, and an emerging "intelligence overhang." The piece includes sponsor mentions and concrete examples of agentic browser automation uncovering bugs and handling shopping flows that sometimes require human intervention (CAPTCHAs).
The newsletter reports a blind benchmark where Claude Opus 5 led and describes practical agentic browser and agent workflows; useful to developers and product teams but not a platform-level policy or major industry shift.
Wichtigste Kernpunkte & Evidenz
- Claude Opus 5 finished first in a seven-model blind benchmark with an overall index score of 78, just ahead of Claude Sonnet 5 (77) and GPT-5.6 Sol (76).
- Opus 5 was the only model to receive straight 5s in the front-end design section of the benchmark.
- Gemini 3.1 Pro finished at the bottom of the benchmark; Claire scored it 32 while the LLM judge scored it 66.
- Using Codex to control a browser produced more exhaustive QA coverage than human testing and uncovered a blocking bug in an onboarding flow.
- Cursor plus a Raspberry Pi enabled Maddie Reese (with limited coding experience) to build hardware projects including a Twitter pager, an AI-powered receipt printer, and a personal API.
