OpenAI charges your card directly. Anthropic sends a PDF invoice to a shared inbox nobody monitors. Vercel bills your GitHub org under a separate email. Railway deducts from a prepaid balance you forgot existed.
You discover the damage 30 days later when the statement arrives and someone has to reverse-engineer a spreadsheet to figure out which engineer left a testing loop running for three weeks.
Per-model cost breakdown for OpenAI and Anthropic — usage mapped to your projects and time windows, not just a monthly total from a PDF invoice.
Automated anomaly detection flags when a model's usage spikes overnight, so you intervene before a junior engineer's eval script becomes a $5,000 mistake.

02 / API costs
Per-model AI costs,
down to the token.
An OpenAI invoice tells you nothing. Prism hooks into usage endpoints to break cost down by model, project, and time window. See exactly which model is eating your budget.
Catch when an engineer runs expensive gpt-4 evals instead of a cheaper model.
03 / Stay in control
Budget alerts
before the spike hits.
You shouldn't discover a runaway script on the monthly statement. Prism automatically flags when 24-hour spend exceeds 3× your 7-day average and pings your Slack channel before the damage compounds.
Workspace /eval-sandbox shows 400% increase in gpt-4.1 usage over the last 2 hours.
