Frontier labs researcher: 5 engineers can now build RL environments once bought for 8 figures

A researcher friend who worked at two frontier labs says five research engineers could now build the RL environments she used to buy from a big data company for seven-to-eight figures.

The poster's takeaway: if we know what good looks like, agents can multiply our output endlessly — hire for missing expertise, not more hands.

Notable on two fronts: the cost of producing frontier-grade RL environments has collapsed from eight-figure procurement to a small in-house team, and "a few experts + agent leverage" is becoming the staffing model at frontier labs.
