Five frontier models port DHH's ttfx challenge with retrieval instead of context — 37/37 gated effects each, provider-billed ledgers included

Who this is for

A researcher or infra founder who wants proof that retrieval beats stuffing the window — DHH's ttfx, 37/37 gated effects, billed ledgers.

Five frontier models, 37/37 each, provider-billed ledgers included. This is a receipt, not a tweet.

Rust monolith is a lot to hand a newcomer. Easy to quote the score and ignore the harness.

Explain the gate, share the ledgers, review a rerun.

Pay the provider bills or chase every new model card.
