Meta AI Updates: May 15, 2026

1. PyTorch 2.12 ships with 100x faster batched eigendecomposition and CUDA 13.2

Meta. PyTorch 2.12 reached general availability with a new cuSolver-backed linalg.eigh that is up to 100x faster on batched problems, fused Adagrad, torch.export support for MX (float8_e8m0fnu) quantization, torch.cond branches that stay on the GPU via CUDA 12.4 conditional IF nodes, and an experimental CUDA 13.2 build (CUDA 12.8 wheels are deprecated). The shipment closes out 2,926 commits from 457 contributors and fully deprecates TorchScript in favor of torch.export and ExecuTorch. Source

2. Incognito Chat for Meta AI ships on WhatsApp and the standalone app

Meta. Meta’s newsroom detailed Incognito Chat, an “invisible-to-Meta” mode for Meta AI that runs inside WhatsApp’s Private Processing TEEs, auto-deletes conversations, and is excluded from ad targeting and AI training. The post also previews “Sidechat,” a coming feature that brings the same Private Processing protections to AI assistance inside ongoing WhatsApp conversations. Useful primary-source detail for any team integrating with Meta’s AI surfaces and weighing data-retention claims. Source

3. Business AI lands in WhatsApp Business in India

Meta. Meta launched Business AI directly inside the WhatsApp Business app for Indian small businesses, supporting all native Indian languages and 24/7 customer support without external tooling. Owners point the AI at uploaded product catalogs and business docs to handle FAQs, recommend products, capture leads, book appointments, and (soon) accept UPI payments, with a human-takeover toggle on every conversation. Pilot businesses cited in the post report 80-90% after-hours conversion rates and 40% sales lifts. Source

4. Instagram Instants leans on Meta’s moderation and teen-safety stack

Meta. Meta’s launch of Instants, an ephemeral Close-Friends photo sharing surface on Instagram, has no headline AI angle but ties into existing classifier-driven safeguards: Teen Accounts and Family Center integration, Sleep Mode notification gating (10pm-7am), and screenshot/recording prevention all flow from the same moderation infrastructure Meta has been building out across its app family. Worth tracking for how Meta is operationalizing teen-safety AI in new product surfaces. Source
