Terms of Service

What we sell today: the AI essentials course (AI 八讲), for people who want to start using AI on everyday work and need no background; the AI one-person-company course (OPCS), for people trying a personal project or a small business, with no coding required, currently sold as a self-paced video course; the AI marketing and customer-acquisition bootcamp (OPCM), for people who already have a product, service, or business to sell; the enterprise AI delivery bootcamp (FDE), for people who write Python or TypeScript; and Muse in Practice (Muse 实战课), for people who want AI to do real work rather than just chat, a self-paced video course on putting Meta's Muse assistant to work. Muse in Practice is made by BayAI Circle and is not affiliated with Meta. We do not sell any physical product at the moment; the book The Cognitive Machine (《认知机器》) is off the shelf and cannot be ordered.

Cohorts, dates, prices, and whether a product is on sale are shown on that product's own page, and those pages govern. Nothing on this page is an offer to sell a cohort that is not open for enrollment.

You must be at least 18 years old and able to form a binding contract. You agree to provide accurate information and to keep your account secure. If you are enrolling or ordering on behalf of an organization, you confirm you are authorized to bind it to these Terms.

What you buy is tied to the account you sign in with. Do not share your account, password, one-time sign-in codes, course links, or downloaded materials. We may suspend an account we reasonably believe is shared, resold, or used to redistribute materials, and we may do so without a refund where the Refund Policy does not otherwise entitle you to one.

Prices are shown on the relevant product page. All payments — cards, Apple/Google Pay, and Alipay — are processed by Stripe and charged in US dollars. You authorize us to charge the amount shown at checkout, plus any applicable taxes.

Where seats are limited, enrollment is confirmed only after successful payment. If you upgrade from one course to another by paying the difference, the total is the list price of the target course at the time of the upgrade, and your enrollment will consist of two separate charges.

A self-paced recorded course gives you its recorded lessons, and any courseware it includes, on your account, to watch whenever you like. It has no live sessions, no real-time Q&A, and no attendance requirement; where the course includes a student community, questions are answered there.

A live cohort is taught live on a published schedule, and sessions are recorded for replay. Schedules, instructors, platforms, venues, and curriculum may change for reasons beyond our control; we will give reasonable notice of material changes. If we cancel a live cohort outright, we will offer you a transfer to another cohort or a full refund.

Where a product page says a recorded course is replayable for life, we mean access without a fixed expiry date. If a course must be taken down for reasons beyond our control, we will give reasonable notice and offer a comparable alternative.

Students who meet the completion criteria receive a certificate of completion with a verifiable link (bayaiu.ai/verify/…). On the courses CSTU co-produces (AI Essentials and OPCS) it is co-issued by CSTU and BayAI Circle; on the others it is issued by BayAI Circle alone, and each certificate names its own issuer. The certificate is evidence of completing the course. It is not a degree, academic credit, or a professional license.

For a live cohort, the completion criteria are at least 80% attendance and submission of the capstone project. The 80% attendance requirement is a live-cohort rule. Completion for the self-paced recorded course means watching all session recordings in full. Progress is taken from the playback records on your account.

We may decline to issue, or may revoke and invalidate the verification link of, a certificate obtained through cheating, attendance by another person, or fabricated submissions.

Refunds are governed by our Refund Policy at bayaiu.ai/legal/refund, which sets out separate rules for self-paced recorded courses and for live cohorts. The self-paced recorded courses — the OPCS self-paced video course and Muse in Practice — are non-refundable.

Where a course includes a student community, your purchase includes access to it, and questions about that course are answered there. Be civil; do not post other people's private information, spam or recruit, or share course materials, recordings, or account access outside the community. We may remove content or revoke community access for conduct that harms other students; on its own, that does not entitle you to a refund.

Signed-in users may join the affiliate program and receive a referral link. We pay the stated commission on qualifying, paid enrollments attributed to your link; self-referral and fraudulent or misleading promotion are not allowed, including any claim of income, audience growth, admission, or employment outcomes. Commission rates, discounts, attribution windows, and payouts may be adjusted, withheld for suspected abuse, or discontinued at our discretion. Payouts are made manually after review.

Course materials, recordings, and site content are owned by us or our licensors and provided for your personal, non-commercial learning. You may not screen-record, download outside the tools we provide, copy, resell, publicly share, or redistribute them, or use them to train or fine-tune a model, without written permission. You agree not to misuse the service, disrupt live sessions, or infringe others' rights.

Work you create during a course stays yours. If you ask us to feature it, you give us permission to show it on our site and in our materials, and you can withdraw that permission for future use at any time.

Everything we sell is educational. We do not promise or guarantee any income, revenue, audience growth, admission, job, or other outcome. Examples and case studies are illustrative, not promises. Your results depend on many factors outside our control.

Nothing we teach or publish, and nothing in any book we sell, is investment, legal, tax, or medical advice.

Our registration with California's Bureau for Private Postsecondary Education (BPPE) is in progress. Nothing on this site should be read as a statement that registration is complete. Our courses are non-degree training, and the certificate is evidence of completion — not a degree, academic credit, or a professional license.

This is the version of OPCS currently on sale: $99 for the complete eight-session recordings, all courseware, and the student community — start any time, replay for life. It has no live sessions, no real-time Q&A, and no attendance requirement; questions are answered in the student community.

To complete this version, watch all session recordings in full; the ≥80% attendance rule belongs to the live cohort and does not apply here. Any certificate issued for this version is evidence of completion — not a degree, academic credit, or a professional license. This version is non-refundable; see the OPCS self-paced section of the Refund Policy.

The OPCS live season — the cohort that began June 24, 2026, online $199 / in-person $299 — has finished and is no longer sold. The date of the next live cohort is to be confirmed, and nothing here commits us to one.

For students who enrolled in that cohort, the live-cohort terms continue to apply: 16 hours taught live over four weeks, recorded for replay, with completion at ≥80% attendance plus the capstone project. That certificate is evidence of completion — not a degree, academic credit, or a professional license.

The AI essentials course is for people who want to use AI on everyday work problems first, and requires no background. Its cohort, schedule, price, and sale status are shown on the course page. If you join after the cohort has started, you can catch up on the sessions already taught through their replays.

Completion and certificates follow the general certificate terms above; the ≥80% attendance requirement applies to live cohorts. The certificate is evidence of completion — not a degree, academic credit, or a professional license.

OPCM is for people who already have a product, service, or business and need to sell it. Its cohort, schedule, price, and sale status are shown on the course page; if you join after the cohort has started, you can catch up through the replays.

The course teaches methods, tools, and workflows. We do not promise any customer, audience-growth, or revenue result, and any distribution tooling we hand out is yours to run under your own accounts and under the rules of the platforms you publish to. Completion and certificates follow the general certificate terms above; the certificate is evidence of completion — not a degree, academic credit, or a professional license.

FDE is for people who write Python or TypeScript and want to work on enterprise AI projects. The first cohort's start date is to be confirmed; until we publish a schedule, nothing here commits us to a date, and any enrollment we open before then is subject to the dates published at that time.

Even where a track includes mock interviews, portfolio review, or introductions, we do not promise any interview, referral, admission, or employment outcome. Work you do on sample or partner projects is subject to any confidentiality terms we tell you about in advance. Completion and certificates follow the general certificate terms above; the certificate is evidence of completion — not a degree, academic credit, or a professional license.

Muse in Practice is a self-paced video course of 27 recorded lessons on putting Muse, Meta's personal AI assistant, to work. It is sold at a single price of $39, paid once, as shown on the course page and at checkout. All 27 lessons are available as soon as you pay. It has no live sessions and no attendance requirement.

Muse is a product and trademark of Meta. This course is made by BayAI Circle and is not affiliated with Meta. Muse is currently available only in the United States, so you may not be able to use it elsewhere; check that you can use Muse before you buy. The course fee does not include any Muse subscription; Muse and its free and paid plans are provided by Meta. Demonstrations show Muse as it was when each lesson was recorded, and Meta may change its interface and features.

To complete this course, watch all of its lessons in full; the ≥80% attendance rule belongs to live cohorts and does not apply here. Its certificate is issued by BayAI Circle alone and is evidence of completion — not a degree, academic credit, or a professional license. This course is non-refundable; see the Muse in Practice section of the Refund Policy. If you are charged twice or never get access, we will refund it.

The Cognitive Machine (《认知机器》) is not currently on sale. It is off the shelf while we settle printing and fulfilment, no orders can be placed, and no order is outstanding. This section describes how it was sold and how it would be sold again: a physical book on pre-order, meaning the copy is not yet shipped when you order, with the estimated ship date, the editions available, and shipping fees shown on the product page at checkout. Ship dates would be estimates and may move; we would tell you about a material delay. If the book goes back on sale, the terms in force at that time will be published on the product page before you can order.

These shipping terms would apply if the book goes back on sale. Title and risk of loss pass when we hand the order to the carrier. International orders may incur customs duties or import taxes, which are the recipient's responsibility. The course refund rules do not apply to physical products; return and refund terms for them will be published on the product page before you can order. If you ever receive a damaged book or an order does not arrive, email contact@bayaiu.ai and we will make it right.

The service is provided "as is" and "as available" without warranties of any kind, to the fullest extent permitted by law. To the maximum extent permitted by law, our total liability for any claim relating to a product is limited to the amount you paid for that product in the twelve months before the claim, and we are not liable for indirect, incidental, special, or consequential damages.

These Terms are governed by the laws of the State of California, without regard to conflict-of-laws rules. Disputes will be resolved in the state or federal courts located in California, unless applicable law requires otherwise. Nothing here waives rights you cannot waive under applicable consumer or education law.

We may update these Terms and will revise the “Last updated” date; material changes will be communicated where reasonable. Questions: contact@bayaiu.ai.
