Instagram Tests Collab Posts With Up To 16 Accounts
Instagram has been observed testing expanded Collab post capabilities after a high‑profile creator’s post included 15 collab partners (suggesting up to 16 accounts including the author). Instagram’s help page still states a limit of five collaborators, and industry observers (including Matt Navarra and Rachel Karten) report Meta is not currently planning an official expansion. The example post was by skater Alysa Liu; the article notes Instagram has previously surfaced feature expansions (e.g., >20 carousel visuals) that did not roll out broadly. The report was published on OnlineMarketing.de on 2026-05-13 by Niklas Lewanczik.
Feature test by a major social platform (Instagram/Meta) could affect creator workflows, reach and influencer marketing strategies, but no official rollout or policy change announced.

Instagram Carousels Now Support 20+ Images
Instagram is expanding its Carousel post capability beyond the previous limit of 20 visuals, enabling posts with 20 or more images and videos, a change that also applies to Threads. The format remains one of the most engaging on the platform, though its reach still lags Reels. Notably, Adam Mosseri posted a Carousel with 23 visuals, and a Rings Awards post featured 26 visuals, illustrating real-world use of the extended Carousel. Instagram also confirmed a new swipe-enabled navigation layout that is ready for broader rollout. It remains unclear whether the 20+ visuals feature will be universally available to all users yet, as testing continues and some commentators question the necessity of more than 20 visuals. The development sits within broader creator storytelling use cases, such as product launches or behind-the-scenes content, and underscores Instagram’s ongoing feature evolution for creators.

Aimed initially at businesses, the agent can connect to internal systems and external tools, use custom skills, and even choose from third-party models like Anthropic's Claude. It will have its own Workspace account with an email address, and will write its own audit trail. Early testers include On, Shopify, and PayPal. Gemini has over 1 billion monthly active users, and nearly 90% of Fortune 100 companies use Gemini Enterprise.
