Who should you follow for AI news?

For a quick scan of Korean AI coverage, start with CHOI; for explanations, AI Coffee Chat; for screen-led practice, Yun Jadong. Try Builder Josh for other teams’ experiences, or the Nomad Coders newsletter for a weekly roundup.

This is an English guide to Korean-language sources, using the original article’s October 2026 observation window. It does not promise English source captions or describe today’s publishing frequency. The distinction is what you want from a news item: notice it, understand it, try it or assess its use in a team.

Counts cover material collected into INFLFEED from October 10 through the afternoon of October 23, 2026, and may undercount actual publication. They measure volume, not quality. CHOI and Yun offer a high reading volume; Josh also publishes frequently across Shorts and Threads. AI Coffee Chat posts less often with more to read per item. Nomad Coders’ Friday newsletter was not collected into the INFLFEED feed; email delivery requires a separate subscription.

Choose a pairing for your work

• Non-developer: Yun Jadong for a first exercise, then AI Coffee Chat to understand what a feature changes.
• Product or operations role: CHOI for the day’s announcements, then Builder Josh for a team’s adoption account.
• Developer: CHOI for frequent updates and Nomad Coders for a weekly synthesis. The newsletter can be read on the web without subscribing.

These pairings are editorial suggestions, not outcomes measured for each profession. Sample the sources before choosing.

CHOI — scan frequent announcements

Useful if you want to notice new models and tools or assess what might matter to your team.

On October 17 at 18:48 KST, a DeepSeek update explicitly qualified the figures as the company’s own measurements. On October 18 at 22:56, a weekly roundup grouped 45 AI news items.

A 2024 Threads reader reported finding a shared prompt useful. In a 2025 interview, the operator also acknowledged criticism of alarmist marketing and hype. These are particular reactions, not a representative satisfaction measure.

AI Coffee Chat — unpack one feature

Useful for a non-developer exploring automation or a first web app.

An October 15, 08:11 KST post summarized four changes in a Claude Code desktop update. An October 21, 10:32 post discussed the create-canvas skill and its possible implications for design tools.

One of two reviews on the paid Coloso course page praised the substance and considered it worthwhile for people using AI only at a basic level. A creator-published class retrospective acknowledged that some participants found the later material demanding. The original research did not find a separate community assessment; that is an evidence limit, not proof that none exists.

Builder Josh — follow an interview into the details

Useful for founders and product teams considering AI adoption, or aspiring builders examining a first SaaS product.

The October 19 newsletter, published at 08:00 KST, discussed swyx’s experiment reproducing a SaaS product, reporting that five of 72 attempts were judged usable. An October 20 interview with Genesis Lab CTO Yoo Dae-hoon explored writing an ontology, followed by a newsletter account.

A Brunch reader valued the concrete guest examples and discussion of risk. In his own newsletter, Josh reported community feedback about being unable to ask questions in recorded classes and material lagging AI developments. Keep reader reactions and creator-published feedback distinct from independent effectiveness evidence.

Yun Jadong — begin with the screen

Useful for first-time AI users or people investigating workplace training.

The October 17 beginner ChatGPT video, published at 18:00 KST, covered signup, plans and asking questions. The October 22 video, also at 18:00, presented nine AI-browser tasks from consultant Lee Jong-woo’s recorded class.

A Tistory account of a joint livestream praised the combination of practical automation and ways of thinking about opportunities. Yun himself wrote that many videos used AI editing and acknowledged room to improve their quality.

Nomad Coders — read a weekly developer perspective

Useful if you prefer a weekly Korean roundup of development and AI.

The October 16 issue, #365, reported research in which code volume grew by 30% after agent adoption while completed features did not. The October 23 issue, #366, led with a PHP-core vulnerability and the circumstances of an earlier-than-planned announcement. These are examples of what the newsletter covered, not independent verification here of every underlying claim.

A 2024 developer blog appreciated its approachable technology coverage and community role. The signup page disclosed possible promotional information. The original research found no separate critical account; absence from that search is not a universal finding.

The same announcement, three treatments

The original article compared coverage of the October 22 Claude Duet announcement. Treat the availability details as what the sources said then, not current eligibility guidance.

CHOI’s 09:00 KST post condensed the announced functions, competitive context and US Pro/Max waitlist conditions. It was one of more than 20 news posts on that day.

Yun’s five-minute video, posted at 10:10 KST, and the accompanying Threads post explained the reported US-account restriction and proposed three preparatory actions for viewers in Korea.

A short alert, a fuller explanation and a proposed action answer different needs. Choose a manageable pair instead of trying to follow everyone. When news prompts a tool change, read how to decide whether switching models helps your own work.
