Meta Unveils Generative Ads Model GEM
Meta is advancing its advertising technology with the Generative Ads Model (GEM), an AI-powered system designed to optimize ad performance across Facebook and Instagram and to automate campaign design. GEM is trained on ad content and user engagement data from ads and organic interactions, employing a post-training technique with knowledge transfer and a scalable architecture that increases parameter counts for more precise predictions. Meta had already observed positive effects, including growth in ad conversions (about 5% on Instagram and 3% on Facebook Feed) after GEM’s introduction earlier in the year. The company envisions scaling GEM with larger compute clusters, inference-time scaling, and agentic, insight-driven advertiser automation to boost ROAS, while noting potential benefits such as reducing scam ads. The platform's broad data base—WhatsApp, Facebook, and Instagram with hundreds of millions to billions of users—underpins GEM’s capabilities.

Meta's ROIC Strategy: GEM Now, LLMs Later
ChipStrat analyzes Meta’s capital allocation approach: prioritize GEM (Generative Ads Recommendation Model) now to generate immediate, measurable ROI in ad ranking and monetization, while investing in frontier LLMs later for layered upside. Meta treats GEM as a large-scale teacher model that transfers knowledge to smaller, latency-sensitive serving models, keeping inference costs low. The company reports concrete ad-performance gains tied to recent model and infrastructure investments (+5% Instagram conversions; +3% Facebook Feed conversions; +3.5% Facebook ad clicks in Q4). Meta is also diversifying compute (NVIDIA, AMD, and custom MTIA silicon) and unifying ranking across paid and organic content. Concurrently, Meta funds Superintelligence Labs (co-led by Alexandr Wang and Nat Friedman) to build frontier LLMs that could further enhance recommendations, creative generation, and content localization.
Google launches unified agentic AI for Gemini
At a Google Cloud event on Thursday, Google announced it is bringing agentic AI to its Gemini assistant, launching a unified agent that can autonomously plan and execute tasks on behalf of users. 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.
