BCG가 발표한 AI 성숙도 보고서에 따르면 작년 견고한 추격자에서 올해는 선도국으로 진입했습니다. 보고서에서는 한국의 독파모와 공공분야 컴퓨팅 인프라, 생태계 투자 전략을 높게 평가했습니다. AI전략위는 부처와 함께 실질적 성과 만드는데 집중하겠습니다.

Andrej Karpathy joined Anthropic to run a team pointing Claude at Anthropic's own pretraining research
a model helping build the model that replaces it. that part is on the record
what's public and worth stealing today: Anthropic's own Claude cookbook on building knowledge graphs
> extract - pull entities and claims out of raw text
> resolve - figure out which mentions are the same thing
> assemble - wire them with typed edges
> query - ask what no single document could answer
four steps, free, sitting in the repo while the timeline chases the hype
learn them this weekend and you walk into Monday with the exact skill getting handed the AI architecture work this year
start with the cookbook, then read the article below

Elon Musk, yolculuk sırasında elektrikli aracınızı %100 şarj etmenin neden bir hata olduğunu açıklıyor:
Yolculuk sırasında, içgüdüsel olarak pili tamamen doldurmak istiyorsunuz.
Böylece bir benzin deposuna davranırsınız.
Ama bir pil, benzin deposu gibi çalışmaz.
Yaklaşık %80'e kadar şarj edin. %10'un altına düşene kadar sürün. Tekrarlayın.
Bu, sadece uzun yolculuklar için geçerli; şarj istasyonunda mümkün olan en az zamanı geçirmek istediğinizde.
Elon: " %80'den %100'e çıkmak, %0'dan %80'e çıkmak kadar zaman alır."
Sebep, pilin içinde olan biten.
Lityum iyonları bir taraftan diğerine seyahat eder, yerleşecek bir yer arar.
Onları, park yeri avlayan arabalar gibi düşünün.
Otopark boşken, hemen içeri dalarlar.
Doldukça, tıka basa dolu bir alışveriş merkezinde olduğu gibi dolaşmak zorunda kalırlar.
Yani pil ne kadar doluya yaklaşırsa, şarj o kadar yavaşlar.
Son birkaç yer, bulunması en uzun sürenlerdir.

Congrats to @GoogleAI's Gemini 4 Argon for taking the top spot of our Humanity's Sixth Sense (HSS) benchmark with a score of 55.4%, edging out GPT-6-Astra at 53.6%. 🥇
HSS tests AI’s ability to reason beyond what’s visible, from hidden objects to predicting what happens next and understanding human behavior.
We took a closer look at performance across categories, and that’s where things get interesting. 👀🧵

랜섬웨어 그룹 ‘논’(N0n)은 13일 자신들의 다크웹 유출 전용 사이트(DLS)에 국내 항만·해운 기업 12곳을 피해 기업으로 올렸다. 이들은 자신들의 비트코인 지갑 주소를 적어둔 채 수백만달러에 달하는 비트코인을 요구하고 있다. 19일 오후 1시까지 비용을 지불하지 않으면 탈취한 모든 데이터를 공개하겠다고 협박하고 있다.
국내 피해 기업은 △부산신항만 △동국제강 △삼주마리타임 △유수로지스틱스 △BKH IDC △고려훼리 △새한마린 △동원글로벌터미널부산 △마산아이포트 △비엔씨티 △폴라리스쉬핑 △동아탱커 등 12곳이다. 이들 기업의 내부 데이터로 보이는 샘플 파일명을 명시했다.
다만 아직 내부 데이터의 원본 파일을 공개하지는 않은 상태다. 협상에 응하지 않을 경우 순차적으로 탈취한 데이터를 공개할 것으로 예상된다. 앞서 이 랜섬웨어 그룹은 기업을 공격해 데이터를 탈취하고, 협상에 응하지 않자 이를 공개한 바 있다.

China has killed the entire vector database industry.
They open-sourced TencentDB Agent Memory. It gives any AI agent long-term memory that runs 100% locally.
No Pinecone. No cloud APIs. No repeating yourself every session.
- 61% fewer tokens
- PersonaMem accuracy: 48% → 76%
- Zero external API dependencies
- Runs on plain SQLite
Most memory systems compress your history into an opaque vector pile. when recall goes wrong, you're guessing. this one doesn't compress, it builds a semantic pyramid.
L0 Conversation → L1 Atom → L2 Scenario → L3 Persona.
Short-term state gets encoded as a Mermaid graph in your agent's context. verbose tool logs get offloaded to disk. when the agent needs proof, it drills back via node_id to the exact raw log.
no lossy compression. every layer is readable markdown you can just open and inspect.
5.1k stars. 100% Open Source.
