Techniques such as anonymized cost tracking, prompt caching checkpoint injection and per-request cost visibility to contain inference spend.
A teardown of Claude Code 2.1.278's config files and network traffic finds background requests behind the idle summary, the follow-up suggestion and every permission decision, plus a model switch that pays to rewrite the whole cache.

Forcepoint's unguarded research agent ran 500 tool calls for a simulated $10, a total set by the test's own ceiling, while the same scenario with a call budget, recursion cap and circuit breaker ended after one call and $0.02.
Reality
The seat fee covers access and no tokens, so every prompt in Claude, Claude Code and Cowork bills to the organisation at API rates. The one control Anthropic's help page describes is an admin-set spend limit.

A dev.to post argues the OWASP Top 10 for LLM Applications 2025 is a list of things a better model will not fix, including over-scoped permissions, unvalidated agent output, and retry loops that bill by the token.
Reality
AI Gateway Budgets went generally available with ceilings at team, project, key and teammate scope. The check runs at the start of each request, so a tight loop can finish slightly past the number you set.
Reality
A consultant's six-month log across forty shipped Python automations reports build time 38 percent below baseline and client revisions halved, with an explicit warning that React work sits outside the sample.
Reality
One team's forty lines of Go moved 81% of requests to a cheaper model and cut the bill 71%, but the arithmetic says the win came from a boring traffic mix and a wide price gap, and the bill it pays is tail latency.
Reality
A dev.to postmortem burned $1,900 against a $600 cap after the alert arrived exactly on time, and the fix it lands on is a reservation that refuses the call before any network I/O rather than a better threshold.

A 2.5-year retrospective spanning more than 250 engineering teams credits a LiteLLM-based API proxy, stood up in January 2024, for metering adoption and forcing client upgrades.
