Frontier agents have crossed a cost threshold at which an autonomous model run can produce a full systems artifact such as a multi-architecture C compiler in Rust for roughly $20,000, while API pricing is $5/$25 per million tokens. This makes autonomous execution of months-long engineering tasks economically viable today.
Reliability and economics of agentic coding now compete with human engineering contracts; deployments should budget for long-horizon autonomous runs rather than treating per-call cost as the only metric.
As token prices hyper-deflate, any well-specified, verifiable knowledge-work task becomes a candidate for supervised autonomous execution.
Building a C compiler across multiple processor architectures in Rust for $20,000 from scratch.
Cost is $5 / $25 per million tokens.
Complex engineering and research tasks that previously took human teams months can now be executed autonomously for minimal cost.
