Validation — early access
LLM Budget Guard enforces hard cutoffs at the provider — across OpenAI, Anthropic, and DeepSeek — before runaway agents burn $47K in 11 days or get your account terminated.
Founding-team pricing locked for life. No spam, ever.

cheaper inference (DeepSeek v4) — bigger blast radius
Three real failure modes we keep hearing from teams shipping autonomous agents. None of them get caught by an alert thresholds dashboard.
Four AI agents looping on a broken retry policy. By the time the Slack alert fired on Monday, the bill was already past five figures. Alerts notice — they don't stop.
Belo (agritech) had 110 OpenAI accounts terminated for misuse spikes their dashboards never flagged in time. No appeals. No data export. Provider trust is now infrastructure risk.
Cheaper inference means more agents, longer chains, riskier loops. The blast radius of a runaway is bigger every quarter — even when the per-token price is lower.
Until 2025, LLM cost was a finance problem. You overshot budget, you negotiated with your CFO, you moved on. Two things broke that calm:
An alert at 80% of budget was already too late in 2024. In 2026, it's a liability.
Enforcement, not observation. Built on top of the same read-only-key model LLMeter uses today.
Set a daily/monthly token budget. We rotate down provider keys or pause the org at the API gateway when you hit it. Agents stop. The invoice stops.
Detect the spend curves that precede provider terminations — repeated rate-limit errors, abnormal usage clusters, sudden 10× volume — and freeze before TOS triggers.
OpenAI, Anthropic, DeepSeek, OpenRouter. One enforced budget across all of them. No more juggling three dashboards while a fourth provider drains.
Cap individual agents, services, or API keys. A misbehaving worker can't take down your whole budget — just its own slice.
A panic button that disables every connected provider key in under 2 seconds. For when you see the spike and don't have time to log into four dashboards.
Slack, email, webhook — but as a status, not a safety net. Enforcement does the saving; alerts just keep you informed.
Side-by-side: what you have today vs. what enforcement looks like.
| Scenario | Alerts (today) | Budget Guard |
|---|---|---|
| Stops a 3 AM token spiral | No | Yes — provider-side cutoff |
| Prevents account ban from misuse spike | No | Yes — pauses before TOS triggers |
| Multi-provider single ceiling | Per dashboard | One budget across all |
| Per-agent budget enforcement | Rare | Built in |
| Setup time | Hours of dashboarding | Minutes (read-only key + budget) |
| Open source | Sometimes | Yes — AGPL, audit anything |
An alert tells you the fire started. Budget Guard puts it out. We integrate with each provider's API to revoke or rate-limit your keys when limits are hit — so a runaway agent at 3 AM stops automatically instead of escalating into a $47K invoice or a provider ban.
Providers terminate accounts for sudden usage spikes, suspicious traffic patterns, or repeated TOS-adjacent behavior — often with no human review. Belo (agritech) lost 110 OpenAI accounts in a single sweep. As more teams run autonomous agents on cheaper models like DeepSeek v4, the risk of triggering automated enforcement keeps growing.
You connect each provider with a key that has billing/admin scope. When you hit a budget threshold, Budget Guard rotates the active sub-keys, pauses the org, or applies provider-native rate limits — depending on what each platform exposes. The goal: stop spend at the API boundary, not at your application code.
OpenAI, Anthropic, DeepSeek, and OpenRouter — the same set LLMeter monitors today. We're prioritizing providers based on waitlist signal, so if you need others (Google, Mistral, AWS Bedrock), tell us when you sign up.
Yes. Like the rest of LLMeter, Budget Guard will ship under AGPL-3.0. You can self-host, audit the cutoff logic, and verify exactly what runs against your provider keys.
We're validating demand now. Waitlist signups directly determine launch timing — if we hit our threshold this month, the alpha ships in the next sprint. Early signups get founding-team pricing locked for life.
Join the waitlist. We email you the day Budget Guard ships — and lock founding-team pricing for life.
