Grok 4.5 from @spacexai places #2 on the APEX-SWE leaderboard at 51.2% Pass@1 (±6.0), behind Fable 5 (65.5% ±6.2) on our benchmark for real-world software engineering work. It leads Integration (65.0% Pass@1) and places #2 in Observability (37.3% Pass@1), covering multi-step build tasks and diagnosis/debugging respectively. The Integration lead maps directly to the agentic workflows Grok 4.5 was built for: multi-step coding tasks run in collaboration with Cursor. Grok models have improved 30.2 pp in a year on this benchmark: Grok 4 (21.0% Pass@1) to Grok 4.5 (51.2% Pass@1). Congratulations to the xAI and Cursor teams.

Grok 4.5 solved it --- Answer: 더바른정육식당 (The Barun Jeongyuk Sikdang) 📍 서울 강남구 강남대로 482, 신논현/논현 · IG @barun_jo 1. Plate first. The tweet photo is a classic Korean 고깃집 사인 벽 — light vertical wood, white cards in clear plastic sleeves, red stickers “open AI / Ilya Sutskever,” date 2023. 9. 16. That style + Korean date format already points at a local meat house, not a touristy Instagram spot. 2. The only public breadcrumb. A Feb 2025 CHON Facebook post by 신근영 (Shin Keun-young / @rms1155) shares essentially the same plate: he paid for lunch, noticed the signature, and the owner said Ilya (with his Korean wife) had dined and signed. No name given — exactly why the original challenge works. 3. Date unlocks geography. 2023.9.16 lands on Prompter Day Seoul 2023 (SKT × OpenAI), prelims that weekend, finals at Dreamplus Gangnam (신논현/역삼). So search shifted from “random Korea BBQ” → 신논현 / 논현 / 역삼 정육식당 with celebrity signature walls. 4. Shortlist + wall matching. Candidates with dense 사인 벽 near Dreamplus: 더바른정육식당, 산솔 신논현, 대운목장, a few quieter 드-슐랭 정육. Cross-checked public wall photos against the hardware in the tweet (vertical wood + laminated white cards, not door-writing / yellow sticky notes / free-form paper). 5. The lock. Google Images for “더바른정육식당 사인 벽” surfaces the same wall system — same wood, same clear sleeves, same card instagram.com/barun_jo/p/Cuh…

Apple just sued OpenAI, and the wildest part is how they got caught: one candidate screenshotted confidential Apple files on his Apple work laptop hours before his OpenAI interview. Apple reads its own server logs. The recruiting pipeline generated its own evidence trail. The complaint says OpenAI's hardware chief Tang Tan, a 24-year Apple veteran, directed candidates still employed at Apple to bring "actual parts" (batteries, logic boards) to interviews for show and tell sessions. One candidate was surprised, saying he didn't even know you could take those out of the office. Apple also alleges Tan circulated an internal Apple offboarding document to coach new hires on dodging exit security checks, and that a departing engineer kept his Apple laptop, found a bug that still gave him access to Apple's cloud storage, and downloaded dozens of confidential hardware files after joining OpenAI. Then the supplier: OpenAI allegedly got one of Apple's manufacturing partners to demonstrate a proprietary metal finishing technique by letting the partner believe Apple had approved it. Over 400 former Apple employees now work at OpenAI. Apple says it flagged all of this to OpenAI in February and never got a response. Five months later, it filed. The ask reveals the strategy. Apple wants an injunction barring OpenAI from using the secrets, the return of every file, and full discovery into io, right as OpenAI preps its first device launch and an IPO. If a judge grants it, OpenAI may have to prove the device was built clean, component by component, before it ships. The device was supposed to run on the world's best hardware talent. Now its bill of materials is evidence.
