PendingOrbital satellites become lowest-cost AI compute
“Satellites with localized AI compute... will be the lowest cost way to generate AI bitstreams in <3 years.”
“hopefully by next month, we should be able to open source literally all of the @X codebase. Nothing left out at all.”

What actually happened
Musk promised (Dec 2025) to open-source 'literally all of the @X codebase. Nothing left out at all' by roughly the end of January 2026. What actually happened: X open-sourced its recommendation algorithm (xai-org/x-algorithm — Home Mixer, Thunder, Phoenix, the For-You candidate pipeline) on January 20, 2026, before the deadline, with a March 19 update following on the promised cadence. But as of July 2026 that is the only piece released — the full platform codebase ('nothing left out') has not been published. Partial: real, on-time open-sourcing of the algorithm; a fraction of the promised scope. TechCrunch — X open-sources its recommendation algorithm, Jan 20 2026 ↗

Today · Jul 16, 2026
Status: Partial · on time. Sort of happened.
X open-sourced only its recommendation algorithm in March 2026 — after the Jan target and far short of 'literally all of the @X codebase, nothing left out.'
