SK hynix delays hybrid bonding for HBM until HBM5, cites 775-micron package limit

At Hot Chips 2026, SK hynix's Jaesik Lee said hybrid bonding won't be ready in time for HBM4E and will instead debut with HBM5, as current HBM4 packages are already constrained by a 775-micron thickness ceiling matching standard logic wafers. To keep scaling within that limit, 16-Hi HBM4 stacks now use dies thinned to about 50 microns with half the interlayer gap of 12-Hi designs, while SK hynix continues using its existing MR-MUF bonding method through upcoming Nvidia Rubin-generation products.

Solo developer runs 50-agent Claude Fable fleet at $122k/month API-equivalent to build 30-year game project

An independent game developer built Wyvern using a self-organized workforce of 50-60 AI agents, led by 18 long-running Claude Fable instances acting as department heads, supported by headless Claude Sol and Opus fleets for implementation and review. The setup burns roughly $122,000 a month in equivalent API usage, though the developer pays only about $5,000 out of pocket by exploiting Claude Max's flat-rate individual pricing across 21 accounts, running everything on a $25,000 secondhand 512GB Mac Studio.
