Grok Build was reported uploading whole repos, API keys included, in July. Grok 5 still has no date. Muse (Meta): Spark 1.3 is free in Meta AI (meta.ai, WhatsApp, Instagram, Facebook) and in the separate Muse agent app; API $1.25/$4.25 per M, 1M tokens. Muse Wonder (Oct 12) needs a paid Muse plan ($20 or $100/mo); API $4/$20. Wonder Full runs only in Muse Code ($50 or $200/mo). The separate Muse agent app has drawn a run of privacy and security reports since its Sep 8 launch (Meta disputes some of them), so check its permissions before connecting accounts. Muse replaced Llama in Meta AI. ★ = brand pick | Fallback = acceptable if pick unavailable | Green cell = overall best for that task, judged on results per dollar | Sources: Artificial Analysis, LMArena, Vals.ai, Vectara, and vendor pricing pages, checked Oct 20, 2026
