AI vendors we track

Built around the providers your LLM stack runs on

VendorSpies monitors per-token pricing, model-tier reshuffles, and rate-limit changes for the AI vendors shaping today's API spend. Coverage is rolling out in waves — "Tracking now" ships alerts today, "Coming next" is on the roadmap.

OpenAI
Tracking now
GPT, o-series, embeddings, fine-tuning tiers.
Anthropic

Claude Opus, Sonnet, Haiku and prompt-cache pricing.
Google

Mistral

Cohere

AI API pricing is moving faster than contracts can keep up

Per-token pricing shifts, silent rate-limit tightenings, and tier reshuffles land without notice — most teams find out weeks later on a spike in their AI bill.

What VendorSpies does

The early warning system your FinOps team has been missing

Traditional cloud cost tools track what you spend. VendorSpies tracks what your vendors charge — so you can respond before the next silent increase erodes your margins.

Continuous surveillance
Watches 24/7 so you don't have to
VendorSpies polls public AI vendor pricing pages, API docs, and rate-limit schedules around the clock — catching every GPT or Claude price recalibration the moment it ships, not weeks later on your invoice.
Instant alerts
Know within minutes, not months
Get notified the instant an AI vendor changes per-token pricing or tightens rate limits. Every alert includes the delta, the effective date, and vetted alternatives proposed by your AI analyst.
Zero manual effort
Fully automated from day one
Pick the LLM providers your stack runs on, set your thresholds, and let VendorSpies handle the rest. No scrapers to maintain, no spreadsheets to update, no team to dedicate.
Alternative proposals
Escape hatches when vendors overreach
When OpenAI raises per-token pricing or Anthropic tightens a tier, VendorSpies already researched comparable alternatives — evaluated on pricing model, contract flexibility, and feature parity.
Simple by design

Up and running in minutes

No agents to deploy, no vendor APIs to integrate manually. Just connect your stack and let the surveillance begin.

01

Pick your AI vendors

Add the LLM providers and AI APIs your stack depends on. VendorSpies starts tracking their public pricing, model tiers, and rate-limit documentation automatically.

02

Set your thresholds

Define alert sensitivity — from "any change" to "only increases over X%." Tune noise vs. signal so your team only sees what matters to your AI spend.

03

Receive and act

When a change is detected, your team gets an instant alert with a full price-impact analysis and alternative recommendations — ready to act on, not just to interpret.

Lock in founder pricing before general availability
