Agent Coding Workflow Would Cost ~$40k/Month on API Pricing, Dev Reveals

Chris Rackauckas (MIT, Julia ecosystem) reveals measurements from his team's "software factory" agent workflow: paying API list prices instead of subscriptions would run roughly $40k/month, so they rely on Devin and Cursor subscriptions to keep costs down.

He adds the team keeps benchmarking open models for code review to future-proof the stack, since frontier labs are unlikely to sustain offering $40k/month of inference for a few hundred dollars. The interlocutor, ConcentrateAI's @zachmoskow, asks for the architecture and in-depth test results while figuring out minimum credit levels for Opus/Grok models.
