Tokens are insanely cheap at the moment. Through OpenRouter a message to Sonnet costs about $0.001 cents or using Devstral 2512 it's about $0.0001. An extended coding session/feature expansion will cost me about $5 in credits. Split up your codebase so you don't have to feed all of it into the LLM at once and it's a very reasonable.
You’d have to ignore the massive investor ROI expectations or somehow have no capability to look past “at the moment”.
>$0.001 cents
$0.001 (1/10 of a cent) or 0.001 cents (1/1000 of a cent, or $0.00001)?
It cost me ~$750 to find a tricky privilege escalation bug in a complex codebase where I knew the rough specs but didn't have the exploit. There are certainly still many other bugs like that in the codebase, and it would cost $100k-$1MM to explore the rest of the system that deeply with models at or above the capability of Opus 4.6.
It's definitely possible to do a basic pass for much less (I do this with autopen.dev), but it is still very expensive to exhaustively find the harder vulnerabilities.
