The news: TikTok introduced new agentic AI tools within its Symphony ecosystem at Cannes Lions 2026, including a new AI Symphony Agent that combines advertisers’ goals with TikTok platform insights, performance signals, and trends to help create TikTok-first campaigns, source creator content, and identify relevant creators.

• Symphony Agent uses an AI-powered chat experience within Symphony Creative Studio to help advertisers create TikTok ads in minutes.
• In Content Suite, its AI Search feature lets advertisers describe their creative needs, then surfaces relevant TikTok videos that align with campaign goals.
• In TikTok One, Symphony Agent helps brands generate creator briefs, identify and invite creators at scale, and find creators who can localize content across markets.

TikTok also announced a partnership with Dentsu to integrate TikTok Symphony capabilities into Zoyumi, Dentsu’s AI-powered SaaS platform for media activation. Dentsu clients will gain access to Symphony creative tools including image-to-video and digital avatars.

The trend: Influencer marketing is increasingly AI-driven.

• About three-quarters (74%) of influencer marketers already use AI in some capacity, per Linqia; use cases include creative ideation, brief writing, campaign analysis, influencer discovery and vetting, and creative repurposing.
• Nearly half (48%) of influencer marketing agencies report that brands are asking for strategic guidance on AI and automation, per CreatorIQ and Sapio Research—reflecting a shift in client expectations for faster campaign turnaround, measurable ROI, and streamlined creator vetting.
• Marketers cite time savings in campaign management (23.6%), content creation (23.2%), and enhanced performance tracking (16%) as key benefits of using AI for influencer marketing, per 2024 Influencer Marketing Hub data.
• 79% of marketers plan to increase spending on generative AI creator content, up from 70% in 2023, per Influencer Marketing Factory; 76% expect AI to drive growth in creator economy ad spending.

Implications for marketers: TikTok’s AI update could make influencer marketing more efficient and performance-driven, unlocking opportunities for brands to pair creator-led content with faster campaign execution and more data-informed partner selection.

For marketers, implementing capabilities available with AI Symphony Agent will potentially become necessary as adoption grows and competitors scale creator content at a faster rate. Brands that wait too long risk falling behind on speed, personalization, and content volume, though they will still need human oversight to ensure AI-assisted creator content feels authentic, brand-safe, and aligned with audience expectations.
