AI-generated National Day banner displays incorrect Singapore flag
An AI-generated banner for Singapore's 61st National Day displayed a flag missing the crescent and stars, resembling the Indonesian flag, along with other inaccuracies. The community residents' committee replaced the banner after residents reported the errors and manually corrected the flag with paint.
What happened
A banner displayed at Block 409 Kampong Chai Chee to celebrate Singapore's 61st National Day on 19 July 2026 was created using AI image generation. The banner contained multiple errors including one flag depicted with only red and white stripes, omitting the crescent and five stars that appear on the Singapore flag, making it resemble the Indonesian flag.
The banner also showed other inaccuracies including a second flag with four-pointed stars instead of five-pointed stars with incorrect proportions, and the National Stadium mislabeled in English as 'Singapore National Indoor Stadium' rather than 'National Stadium'. By 21 July 2026, residents had painted corrections onto the defective flag with white paint, and the Kampong Chai Chee Residents' Committee replaced the banner.
Reported impact
A resident artist and former civil servant who discovered the errors expressed concern that such mistakes should not occur given the multiple review stages between design and display. She questioned why budget was spent on AI subscriptions rather than hiring professional designers.
The Residents' Committee stated the banner was created by volunteers, many elderly, who were unaware of the errors at the time of completion. The incident prompted reflection on the need to verify AI-generated content for accuracy despite AI being a useful tool.
Index analysis
The failure occurred in post-deployment verification of AI-generated visual content. The system generated a flag image that failed to include essential identifying elements of the Singapore flag, resulting in a design resembling a different nation's flag.
Governance controls
According to the National Heritage Board, flag imagery during National Day may use creative presentation methods but designs should not significantly deviate from the original form to avoid changing its symbolic meaning. The incident demonstrated a gap in quality assurance processes across design, review, and installation stages.
