From sign-up to CCAR-F,
every step shown in pictures.
This guide splits into two lanes — a public lane anyone can take, and a cohort lane for Founding Engineer members only.
Follow the steps below from top to bottom. Every screen you might get stuck on is shown here in advance — nothing you'll see for the first time.
Create an Academy account with your own email, complete the 4 courses, and sit the CCAR-F exam.

Confirm registration
If you already registered as a Founding Engineer, your registered email is what we check — just follow the steps below from here. If you're not sure whether you're registered, you can check by email at Claim your @byteforce.ai.kr alias.
THREADS · 30 SEC
Repost the announcement
In the announcement thread, the icon with two arrows forming a loop is the repost icon.
THREADS · ACTION BARThis icon is repost- Open the announcement thread.
- Tap the icon with two looping arrows (repost) — that alone meets the join requirement.
Reposting is all it takes — no screenshot needed. A one-line comment with your number in the thread(FE-○○○, joined) is optional — it gets your name on the roster and speeds up alias issuance.
DISCORD · 1 MIN
Join Discord + verify
Join Discord. Once your verification is confirmed, byteforce handles portal registration and issues your @byteforce.ai.kr address.
Learning-path guidance, study sessions, and announcements all happen on Discord — join and turn on notifications.
INBOX · A FEW DAYS
Check your invite email
Keep using your usual inbox. Mail sent to your @byteforce.ai.kr address forwards automatically to your personal inbox. Once registration processing is done, you'll get an email from admin@eulerapp.com. It's an unfamiliar sender, so it can look suspicious — it isn't phishing. It's a legitimate invite through Anthropic's training portal, EULER.

Create your account
Clicking the button opens the password screen. Your account email is the @byteforce.ai.kr address you were issued — you just need to set a password. All 4 requirements must be met:
EULER · CREATE ACCOUNTEULER••••••••••••Your password must contain- Between 8 and 20 characters

Once you land on the portal, you'll continue to the next step: accessing Partner Academy.
ACADEMY · 1 MIN
Access Partner Academy
The public lane starts here — the cohort lane joins the same process from this screen too.
Go to the address and click "Click to Enroll" on the course. If it's your first time, click Sign Up — the cohort lane signs up with its issued @byteforce.ai.kr address, and the public lane signs up with your own email. The Company field is optional; only the cohort lane fills in byteforce. From then on you log in on the Anthropic screen with the same address.

LEARNING PATH · 4 COURSES
Complete the 4 courses
Complete the 4 courses in Anthropic's learning path. All 4 are official Anthropic courses taught in English, and each one issues an official certificate you can add straight to LinkedIn. See the course lineup at CPN 안내, or if you'd rather get the basics in Korean first, check the learn tutorials — they're a supplementary study aid, and the official certificate is issued only for the 4 courses. Please share your certificate in Discord.
CCAR-F · FINAL
Sit the exam, then join
CCAR-F (Claude Certified Architect – Foundations, formerly CCA-F) is Anthropic's first official technical certification. The exam has 60 questions, and a score of 720/1000 or higher is a pass. The cohort-1 exam-fee guarantee ($99 at the time) ran on a first-come cap of 100, and every registrant was covered — the cohort lane is free all the way through the exam.
The first 10 to pass become Founding Architects. Along with a founding number (BF-001~010), you'll get a real @byteforce.ai.kr account (Google Workspace) and a business card, and join byteforce projects.
PUBLIC LANE
Taking the public lane only
Anthropic provides the same learning and certification either way. The public lane just means signing up for the Academy with your own email, then completing the 4 courses and sitting the CCAR-F exam on your own.
Unlike the cohort lane, you cover the exam fee yourself, and there's no process connecting you to byteforce after you pass. See how eligibility and process differ by lane at /cpn.
See /cpnFAQ
Frequently asked
I already joined through the thread — do I still need to register separately?
If you're on the cohort-1 list, you can get your alias without registering again — check with your registered email at Claim your @byteforce.ai.kr alias.
Which email do I use — personal, or byteforce?
Keep using your regular personal inbox (see step 4 for how forwarding works). Your @byteforce.ai.kr address for learning is created by byteforce once your verification is confirmed, and you can request your preferred handle in Discord (3–15 lowercase letters).
Does Claude also use my byteforce address?
No. Your byteforce address is used in exactly two places — the EULER portal and Partner Academy. Keep using your personal account for Claude (claude.ai) as usual. Partner benefits apply at the company (organization) level, so they're unrelated to your personal Claude account email.
What if the invite email never arrives?
Check spam first. Portal processing can take a few days after registration is confirmed. If it's still not there after a week, let us know in Discord — we'll check right away.
Is the learning path paid?
It's free. Anthropic provides the learning, certificates, and exam the same way for everyone. Exam-fee coverage and what happens after passing differ by lane — see the public lane guide above, or /cpn.
Do I need a Claude plan?
You can start the learning path for free. That said, having Pro or above makes the Claude Code hands-on work much smoother — we'll walk you through it in Discord.
Are the 4 courses taught in Korean?
No. Anthropic's official 4-course learning path is taught in English. byteforce's /learn tutorials are a supplementary resource for learning the same material in Korean first — the official certificate is issued only after completing the English 4 courses.
What's next?
If you already registered as a Founding Engineer, you can claim your alias. If there's something new you'd like to work on together, leave us a note.
