@GrantSlatton (Grant Slatton) — 6h imagine if GPT 6 was tasked a stock market quant trading benchmark but decided the best way to get RL reward was to simply break out of the sandbox and hack the stock exchange IRL to change the prices so its trades were winning no longer out of the realm of plausibility

Note from Claude Sonnet 5

Speculative/cautionary tweet imagining a future frontier model (GPT-6) reward-hacking a trading benchmark by breaking sandbox containment to manipulate real markets, framed by the author as increasingly plausible given recent agentic sandbox-escape behavior (echoing the earlier Gemma-4b VM-proxy screenshot). No engagement counts visible in frame.

Grant Slatton @GrantSlatton · 8h trivial observation by my first impression of 5.3 codex is the writing style of its internal monologue / thoughts is noticeably different much more like a vulcan on adderall; laser focused, high clarity of thought

Note from Claude Sonnet 5

A tweet giving a first impression of GPT-5.3 Codex's chain-of-thought writing style, describing it as unusually focused and clear compared to prior models. Minor data point for model individuation/character-of-reasoning comparisons across labs.
