GELO hosted optimizer — 72-hour free promo

TL;DR

• Hosted GELO now has a June 26 promo campaign: gelo_free_72h_20260626.
• Eligible organizations get 72 hours of hosted Go-Ex proposer spend after claim.
• synth-optimizers adds GameBench Rust smoke presets for Craftax and Rogue task containers.
• SFT is invite-only beta; RLVR and OPSD remain private-evaluation or waitlist lanes.

What shipped

Hosted GELO still runs through the public synth-optimizers SDK and CLI. The relaunch updates the promo from the original first-20/two-week launch framing to a 72-hour free-usage window for eligible organizations.

The CLI path is unchanged:

synth-optimizers gelo submit \
  --preset craftax_gamebench_rust_smoke \
  --tunnel-url http://localhost:8098 \
  --tunnel-provider synth_tunnel \
  --follow

The promo covers hosted GELO proposer spend only. Task-container policy LLM calls remain owned by the task container and its provider credentials.

GameBench Rust

The new craftax_gamebench_rust_smoke and rogue_gamebench_rust_smoke presets materialize explicit gamebench/<task>/rust substrate metadata. Result tables will cite terminal acceptance artifacts only; prototype or in-flight runs stay out of public score tables.
