Meta

Meta Platforms (formerly Facebook) is one of the world's largest technology companies, founded by Mark Zuckerberg in 2004. It operates Facebook, Instagram, WhatsApp, Messenger and Threads, which together serve over 3 billion daily active users.

Meta runs two AI tracks rather than having chosen one. Its Llama family is the most widely used open-weight language model line in the world, while its Muse models power Meta AI across every Meta platform: the fast Muse Spark and, since October 2026, the larger Muse Wonder, Meta's first frontier model, priced level with Claude Opus 5.5 in its API and available in full only inside Muse Code. Both were developed by Meta Superintelligence Labs, the organization led by Alexandr Wang and assembled through a 14.3 billion dollar deal for Scale AI. Its open licenses vary by model rather than moving in one direction: a compact local-agent model went out under plain Apache 2.0 terms, with none of the user-count restrictions the Llama Community License imposes. The durable pattern is that the tier decides the license — Meta closes what powers its own products and opens what it wants widely adopted. In October 2026 Meta extended that logic upward: once Muse Wonder sat above it, Meta released open weights for Spark as Muse Spark Open, an 816 billion parameter model under a custom license that requires attribution and a separate agreement for any company over 20 million dollars in revenue that resells it as an API. Its strongest model, Wonder, stays closed. Zuckerberg has argued the case in public, on the grounds that superintelligence concentrated in a few hands is itself the safety risk.

Meta One is the paid subscription brand spanning Instagram, Facebook, WhatsApp and the Meta AI app, while Meta AI itself stays free for casual use. Single-app plans sit beneath individual bundles, with creator and business tiers above them adding a verified badge, higher search ranking and impersonation monitoring. It is Meta's first AI revenue stream beyond advertising and a structural change for a company whose AI strategy had been defined by monetizing through ads. One caveat belongs with it: Meta declines to publish the AI usage limits for any tier, saying they vary by country and system conditions, which makes the central benefit of the paid plans the one thing a buyer cannot compare.

The infrastructure behind this is among the largest capital programs of any company, and Meta is building its own accelerators through the MTIA program, designed with Broadcom and manufactured by TSMC, to supplement rather than replace the GPUs it buys in bulk. It is also moving to monetize the buildout directly through Meta Compute, a cloud business selling access to raw computing power and to Meta's own models, in competition with the established hyperscalers — described internally as renting surplus chips between training runs, like empty airline seats.

Its largest consumer AI bet is Muse, a personal agent that connects to a person's own email, calendar, payments, shopping and smart-home accounts and acts inside them rather than returning drafts, running in a dedicated virtual machine where a separate agent must approve anything that reaches the internet. Distribution through WhatsApp gives it a channel no competing agent has. It is also a demanding bet for this company specifically, since the product requires more personal access than any assistant Meta has shipped. Outside researchers have already found flaws, including shared content anyone could locate through public DNS records, which led Meta to pause sharing in October 2026; it fixed the share addresses and turned sharing back on two days later.

In September 2026 Meta turned that stack toward companies with Meta Enterprise Platform, which Zuckerberg called the next major pillar of its business, starting with the Muse agent, a business agent and a coding tool. It hired Chirantan "CJ" Desai, then chief executive of MongoDB, to run it. Meta gave no price, launch date or named customers, so for now it is a stated direction rather than a product a business can buy.
