With open-weights models reaching a level where they can sufficiently be used for agentic coding, the price can be directly compared to the price of GPU rentals: https://vast.ai/ has an H100 at $1.65/hr. which can support ~40 concurrent sessions at 40 tok/s. Depending on your agentic workload, you can stretch that any way you like, but let's say it might support 10 active developers at a speed comparable to Claude Code with Sonnet 4 (which I've read is 90 tok/s) who aren't going crazy with sub-agents.

Let's scale that up: $1.65/hr. is ~$1188/mo. (assuming you're renting the GPU 24/7 which you can speculate to not do, which is probably fine as long as there's not scarcity), and divided by ten is ~$119/mo. per user for 10 users.

Add the service layer on top in order to make this a convenient software service, I think $100/mo. is a bargain for unhindered (as far as it goes) access to a high-quality (as far as they come) agentic coding framework.

Feel free to correct my napkin math, it's done very quickly.
