Obligation:
Transparency
enforcing
Effective:
Aug 2, 2026
Risk tier:
general-purpose
Scope:
Covered providers: persons creating, coding, or otherwise producing a GenAI system publicly accessible within California, without a monthly-user threshold (§ 22757.1(e)). The chapter excludes products, services, websites, or applications providing exclusively non-user-generated videogames (§ 22757.5(a)); before 2029-01-01 it also excludes GenAI systems designed primarily as assistive technology (§ 22757.5(b)).
high-impact
SB 1000 was approved and chaptered on 2026-09-30 as Chapter 861. Its urgency clause makes the amendments immediate; the original chapter became operative on 2026-08-02. The October 1 source comparison uses the official approval/chaptering record and August 30 enrolled text still served by the official Text page. A separately published chaptered or consolidated text was not retrieved; no human Verified or Checked date is renewed.

Requirements

RequirementDetails
Latent disclosureTo the extent technically feasible, include latent disclosure in image, video, audio, or combined content created or altered by the provider's GenAI system, except by minor modification (§ 22757.3(a)); defined minor modifications include brightness, contrast, color, sharpening, saturation, resizing, scaling, cropping, format conversion, and denoising and removal of background noise in audio (§ 22757.1(l))
Latent disclosure contentsConvey directly or through a permanent website the provider name, system name/version, creation or alteration time/date, unique identifier, and whether the system created or altered the content; from 2029-01-01 also state whether the system is designed primarily as assistive technology (§ 22757.3(a)(1))
Persistence and interoperabilityDisclosure must be permanent or extraordinarily difficult to remove or tamper with, compatible with the provider's disclosure verification tool, and compliant or interoperable with widely recognized industry standards (§ 22757.3(a)(2)-(4))
Free disclosure verification toolProvide a free tool assessing whether image, video, audio, or combined content was created or altered, except by minor modification, by the provider's GenAI system; output detected system provenance data (§ 22757.2(a)(1)-(2))
Personal-information outputDo not output detected personal information unless the user to whom the personal information pertains expressly consents in clear, conspicuous plain language to including personal information specified by that user in the content, after notice of what may be output and the permanent digital footprint that cannot be retracted from circulated copies (§ 22757.2(a)(3))
Tool accessibilityMake the tool publicly accessible subject to reasonable security, integrity, or malicious-misuse limits; accept uploads or URLs; support technology including an API for invocation without visiting the provider's website (§ 22757.2(a)(4)-(6))
Feedback loopCollect efficacy feedback and incorporate relevant feedback into improvement attempts (§ 22757.2(b))
Personal-information limitsDo not collect, use, retain, sell, share, or otherwise make available personal information from tool users or processed content beyond what is strictly necessary for compliance, except information used solely to communicate with an opted-in user. Do not condition GenAI system or tool access on information beyond what is strictly necessary (§ 22757.2(c)-(d))
Third-party tool optionA third-party tool may satisfy these duties if compliant with § 22757.2, compatible with the provider's latent disclosures, and clearly and conspicuously accessible through its GenAI system interface (§ 22757.2(e))
Licensee notificationNotify third-party licensees of their chapter obligations when granting a license (§ 22757.3(b)(1))
72-hour responseOn knowledge that an identifiable licensee modified a system out of compliance, terminate authorization within 72 hours or notify the licensee within 72 hours of noncompliance and the AG-reporting requirement (§ 22757.3(b)(2))
Licensee cure and reportingA notified licensee must make the system compliant or cease using or making it available, including copies or modifications, and report its chosen action to the provider within 96 hours. The provider must report to the AG if no report arrives or the report indicates neither required action was taken (§ 22757.3(b)(3)-(4))
Monitoring limitThe licensee-response subdivision does not require monitoring, investigation, or inquiry into licensee use or modification (§ 22757.3(b)(5))
Assistive-technology representationDo not falsely represent that a GenAI system is designed primarily as assistive technology (§ 22757.3(d)); the chapter's pre-2029 assistive-technology exclusion and temporary separate penalty must be read alongside this prohibition

Penalties

ViolationFine
General violation$5,000 per violation; each day a covered provider, large online platform, or capture device manufacturer violates the chapter is a discrete violation (§ 22757.4(a)-(b))
EnforcementCivil action by the AG, a city attorney, or county counsel; prevailing plaintiff recovers reasonable attorney's costs and fees (§ 22757.4(a))
Earlier actionsA civil action brought under § 22757.4 before the amendment's effective date cannot be maintained if the alleged conduct no longer violates the amended chapter (§ 22757.4(c))
False assistive-technology representationExcluded from § 22757.4; temporary § 22757.4.1 provides $50,000 per violation, each day discrete, enforceable by the AG, city attorney, or county counsel with prevailing-plaintiff costs and fees; § 22757.4.1 repeals on 2029-01-01 (§§ 22757.4(d), 22757.4.1)

Transparency
pending
Effective:
Jan 1, 2027
Risk tier:
general-purpose
Scope:
Large online platforms — public-facing social media, file-sharing, mass messaging platforms, or stand-alone search engines distributing content users did not create, exceeding 2,000,000 unique monthly users over the preceding 12 months, excluding broadband internet access services and telecommunications services (§ 22757.1(i)); and GenAI hosting platforms — websites or applications making GenAI source code or model weights available for download to state residents (§ 22757.1(h))
upcoming

Requirements

RequirementDetails
Provenance detectionLarge online platforms must detect whether content distributed on the platform carries provenance data compliant with widely adopted specifications (§ 22757.3.1)
User interface disclosureProvide a user interface disclosing whether system provenance data is available for the content (§ 22757.3.1)
Provenance inspectionAllow users to inspect available system provenance data (§ 22757.3.1)

Penalties

ViolationFine
Per violation$5,000; each day in violation is a discrete violation (§ 22757.4(a)(1), (b))
EnforcementCivil action by the Attorney General, a city attorney, or a county counsel; prevailing plaintiff recovers reasonable attorney's fees and costs (§ 22757.4(a))

Capture Device Latent Disclosure

Obligation:
Transparency
enacted
Effective:
Jan 1, 2028
Risk tier:
general-purpose
Scope:
Capture device manufacturers, for any capture device first produced for sale in California on or after 2028-01-01; a capture device is any device that records photographs, audio, or video, including cameras, mobile phones with built-in cameras or microphones, and voice recorders (§ 22757.1(c)-(d))
upcomingcross-domain
The provenance chain's other end: the rest of the chapter marks content as synthetic, while this section marks content as camera-captured. It reaches hardware manufacturers rather than AI developers, so it lands on companies that may not otherwise track AI regulation — and default-on embedding (subdivision (a)(2)) is a firmware-level design decision with a long lead time.

Requirements

RequirementDetails
User optionProvide the user with the option to include a latent disclosure in captured content (§ 22757.3.3(a)(1))
Disclosure contentsThe latent disclosure conveys the capture device manufacturer's name, the device name and version number, and the time and date of the content's creation or alteration (§ 22757.3.3(a)(1)(A)-(C))
Default embeddingEmbed latent disclosures in content captured by the device by default (§ 22757.3.3(a)(2))
Feasibility limitCompliance is required only to the extent technically feasible and compliant with widely adopted specifications adopted by an established standards-setting body (§ 22757.3.3(b))

Penalties

ViolationFine
Per violation$5,000; each day a capture device manufacturer is in violation is a discrete violation (§ 22757.4(a)(1), (b))
EnforcementCivil action by the Attorney General, a city attorney, or a county counsel; prevailing plaintiff recovers reasonable attorney's fees and costs (§ 22757.4(a))
