AI DAILY · 2026-11-09-3 오늘은 앞선 글에서 다루지 않은 소식 위주로 골랐습니다. AI가 18년 된 양자 복잡도 난제의 증명을 썼다는 발표 , 앤트로픽이 데이터센터용 발전기를 대규모로 확보했다는 보도 , LG의 K-엑사원 2.5 API 무료 개방 , 그리고 로봇 추론을 빠르게 하는 엔비디아의 V플래시 까지, 2026년 11월 9일 기준으로 핵심만 짚어 봅니다. 📰 오늘의 핵심 PSI, 비공개 앤트로픽 모델로 양자 난제 '아론슨-암바이니스 추측' 증명 발표 앤트로픽, 1.7GW 규모 가스 발전기 약 34억 달러 계약 보도 LG AI연구원, K-엑사원 2.5 API 전면 무료 개방 엔비디아 V플래시, 로봇 시각 계획 추론 최대 5.1배 가속 1 PSI, 비공개 앤트로픽 모델로 18년 묵은 양자 난제를 증명했다고 발표 AI 물리학 스타트업 피지컬 슈퍼 인텔리전스(PSI)가 6일(현지시간) 양자 복잡도 분야의 난제인 아론슨-암바이니스 추측 의 완전한 증명을 도출했다고 밝혔습니다. 연구 시작 사흘째에 증명 초안이 나왔고, 수학 검증 도구 린 4(Lean 4)의 검증도 통과했다는 설명입니다. 이 결과는 구조가 없는 무작위 입력에서는 일반 컴퓨터도 양자 알고리즘의 출력을 비교적 적은 횟수의 데이터 조회로 근사해 예측할 수 있다는 내용입니다. 스탠퍼드대 연구진은 이를 검토한 뒤 "여러 연구 흐름을 하나로 결합한 증명"이라고 평가했다고 보도됐습니다. 💡 왜 중요한가 모델 개발사가 아닌 외부 연구 조직이 자체 연구 시스템과 최첨단 모델을 결합해 수학 연구 성과를 냈다는 점이 눈에 띕니다. ⚠️ 알아둘 점 사용한 모델명과 접근 경위는 공개되지 않았고, 논문 전체가 형식 검증된 것은 아니어서 전문가의 추가 검토가 필요합니다. 또 이 결과가 양자 컴퓨터가 일반 컴퓨터보다 빠를 수 없다는 뜻은 아니며, 쇼어 알고리즘처럼 구조를 활용하는 문제의 우위는 그대로입니다. 📎 출처: AI타임스 - PSI ...

Korean Air Lounge Explained | Seat & Membership Eligibility Guide

Planning a trip with Korean Air and wondering whether you can actually enter the lounge before your flight? Many travelers are unsure which seat class or membership tier qualifies, how many miles a lounge visit costs, and whether they can book a seat in advance. This guide gathers the location, eligibility, mileage, reservation, and etiquette rules in one place so you can check everything at a glance. Any difficult or unfamiliar airline mileage terms will be explained one sentence at a time so they are easy to understand.





1. Korean Air Lounge Locations Explained

Korean Air operates lounges across Korea, Japan, and the United States. Domestic lounges are located at Gimpo, Busan, and Jeju, while international lounges are located at Gimpo, Incheon, Busan, Jeju, Nagoya, Narita, Osaka, Fukuoka, New York, Los Angeles, and Honolulu. This means the airport you depart from determines which lounge you can enter, and not every airport has a Korean Air lounge.

International loungesGimpo, Incheon, Busan, Jeju, Nagoya, Narita, Osaka, Fukuoka, New York, Los Angeles, Honolulu

Table explanation: The first row lists the three domestic lounges (Gimpo, Busan, Jeju) available for flights within Korea. The second row lists the eleven international lounges, which add Incheon plus overseas cities in Japan and the United States. This means a domestic ticket only gives access to the three domestic lounges, while an international ticket opens access to the broader international list.

[Key Terms Explained]
Prestige Class: This is Korean Air's name for business class, the seat tier between economy and first class.

2. Seat Class Eligibility Explained

First class passengers may use the first class lounge, and where a dedicated first class lounge is not available, the Prestige lounge is offered instead. Prestige class passengers may use the Prestige lounge, and if they also hold elite SKYPASS status, they may access a higher-tier lounge. This means your entry level is decided first by your seat, and then can be raised by your membership status.

[Key Terms Explained]
SKYPASS: This is Korean Air's frequent flyer program that lets members earn and spend miles and hold membership tiers.

3. Membership Tier Eligibility Explained

First class and Prestige class passengers, plus SKYPASS Million Miler Club, Morning Calm Premium Club, Morning Calm Select Club, and SkyTeam Elite Plus members, may use the lounge without any advance reservation. Eligible members boarding a Korean Air or SkyTeam flight on the day of departure can enter with themselves plus one companion. This means your paid ticket alone may not grant lounge access, but a qualifying membership tier can.

[Key Terms Explained]
SkyTeam Elite Plus: This is the top-tier status in the SkyTeam airline alliance, which grants lounge access across member airlines including Korean Air.

4. Lounge Mileage Bonus Explained

A domestic lounge visit costs 2,000 lounge miles and an international lounge visit costs 4,000 lounge miles. The lounge bonus can be used by up to 4 people together, with 1 voucher used per person, and children aged 2 and older are deducted the same mileage as adults. This means a family of four can enter together, but each person still consumes one voucher's worth of miles.

The lounge bonus voucher is valid for 1 month from the issue date, and after expiry only a refund is possible. It can be used only at a Korean Air-operated Prestige lounge located at your departure airport on the day of a Korean Air flight (flight numbers starting with KE). This means the voucher is tied to a short window and to your actual departure point, not to any lounge you like.

[Key Terms Explained]
Lounge voucher: This is a single-use pass, issued from miles or a benefit, that admits one person to the lounge.

5. Advance Reservation Process Explained

If you use miles or a voucher, you can reserve a lounge in five steps: select the lounge, select the date, select the entry time, select the vouchers, and complete the reservation. Reservations can be made from 30 days before up to the day of use, and the chosen entry time gives a 1-hour window to enter freely (for example, choosing 7 a.m. allows entry between 7 and 8 a.m.). This means you can lock in a spot ahead of time instead of risking a full lounge on the day.

You can select up to 4 vouchers according to the number of guests, and reservations can be cancelled any time up to the day of use. A voucher not used on the reserved date can be reused without a separate cancellation, but cancelling a voucher also cancels its linked lounge reservation. This means unused vouchers are not wasted, yet cancelling the voucher and cancelling the booking go hand in hand.

Eligible passengers for advance reservation are those holding a Korean Air (KE) ticket who use a lounge voucher such as a Morning Calm member benefit voucher, a SKYPASS lounge bonus voucher (miles), or a Korean Air BIZ point benefit voucher. This means the reservation feature is built around voucher holders, while seat-class and top-tier members simply walk in.

6. Etiquette and Precautions Explained

Outside food and drinks may not be brought in, food and beverages provided must be consumed inside the lounge, pets must stay in their carriers, and smoking including e-cigarettes is prohibited. This means the lounge keeps a quiet, shared standard that every guest is expected to follow.

The lounge can only be used at your departure airport on the day of boarding, and your boarding pass must be shown at entry. When using a partner card, a fee may be charged depending on the card company's conditions; infants under 2 years old are admitted free, while children aged 2 and older follow the same voucher or mileage rules as adults. This means access is tied strictly to same-day departure, and only the youngest travelers are exempt from the standard charge.

7. Frequently Asked Questions (FAQ) Explained

Q1. Can I use the lounge without a first class or Prestige ticket?
Yes, you can enter using miles, a voucher, or a qualifying partner card. This means the lounge is not limited only to premium-cabin passengers.

Q2. How far in advance can I reserve a lounge?
Reservations are open from 30 days before up to the day of use. This means you have a full month of lead time but can also book last minute on the day.

Q3. How many people can enter together with a lounge bonus?
Up to 4 people, with 1 voucher used per person. This means each guest still consumes one voucher even when you enter as a group.

Q4. Can I use a lounge at my arrival airport?
No, the lounge can only be used at your departure airport on the day of boarding. This means arrival-side lounge use is not offered.

Q5. Do children pay for the lounge?
Infants under 2 are free, while children 2 and older are charged the same miles as adults. This means only the youngest infants are exempt from the standard deduction.

Q6. Is an unused voucher lost if I don't show up?
No, a voucher not used on the reserved date can be reused without a separate cancellation, within its validity. This means a no-show does not automatically waste the voucher.

Note: Some details above were confirmed via search and may change over time, so please verify the latest information on the official Korean Air website before you travel.
