OpenAI 28-Day Sprint Day 5: Build Polkadot (DOT) on Mobile, Codex Predicts Next Instruction

Beating AI Express, Insight: The shared quota rules previously unearthed from ChatGPT's subscription page by "Bald Guy" Tibor Blaho have now been officially confirmed. OpenAI's latest help documentation clarifies that starting December, ChatGPT and Codex will share a single quota for Plus, Pro, and Business users, while ChatGPT Work's Agent capabilities will be integrated into the regular chat interface. Moving forward, usage will be uniformly calculated based on tokens, with stronger models and more complex tasks typically consuming more quota. However, Instant mode chats will not draw from the shared quota. Users can view their remaining quota and reset time in settings. Ironically, shortly after OpenAI announced doubling quotas for Pro and other plans, it confirmed merging chat and programming services into the same quota pool. The company also reassured users that most will not run out of quota more frequently than they currently do.

Driven by the ongoing artificial intelligence boom, South Korea’s exports continued to post strong growth in October, further boosting the export momentum of its trade-reliant economy. Data released Sunday by South Korea’s Ministry of Trade, Industry and Energy shows that, adjusted for working-day differences, October’s exports rose 76.1% year-on-year to $115.3 billion, below the previous month’s record of $121.1 billion. Unadjusted figures show October exports jumped 93.7% year-on-year, imports rose 36%, resulting in a trade surplus of $42.5 billion. South Korea’s revised year-on-year export growth for September was 83.7%. The sustained strong exports have further reinforced market expectations that the Bank of Korea will raise interest rates this month. Semiconductors remain the main driver of export growth: in October, South Korea’s chip exports surged 259% year-on-year to $56.4 billion, computer exports rose 497%, while petroleum products and auto exports increased 80% and 18% respectively.

US President Donald Trump has repeatedly stated publicly recently that he gets along well with North Korean leader Kim Jong Un, emphasizing that maintaining good relations with nuclear-armed countries is a wise move. This approach aligns with his summit diplomacy toward North Korea during his first term and matches his current second-term preference for keeping communication channels open with leaders of nuclear-armed states. Trump responded to the Binance hack incident today, noting it is currently unclear whether the attack on Binance was carried out by North Korea. If a link to North Korea is ultimately confirmed, the U.S. will engage with Pyongyang. However, the FBI previously issued a statement formally attributing the October 29, 2026 Binance security breach to North Korea, with the virtual assets involved valued at over $60 billion. The FBI has named this North Korean malicious cyber operation "TraderTraitor". If the U.S. pursues negotiations, possible steps include using third parties, intelligence channels, or public pressure to demand the freezing or return of the assets. Trump’s past approach to North Korea has leaned toward "direct communication + personal relations"—whether this will hold in this case remains to be seen. Binance’s connections to Trump family-related businesses (such as stablecoins) may also lead the White House to pay closer attention to the case. Meanwhile, the outlook for a formal U.S.-North Korea summit remains uncertain: Trump previously expressed a desire to meet within the year, but that has cooled recently, and North Korea has not responded actively. If the FBI’s attribution is confirmed and the stolen funds are used for nuclear weapons or missile programs (the U.S. has long accused North Korean hackers of funding its weapons programs), this could become a new issue or friction point in U.S.-North Korea communications.
