Recent price events we've logged

A sample from the broader market — the kind of change subscribers hear about on day one. AI model events live on the LLM price history timeline.

Jun 2025
OpenAI o3 input: $10 → $2 /1M −80%

Largest single cut on a flagship reasoning model — re-shopping the reasoning tier that week saved teams 5× on hard-query workloads.

2024–2025
Gemini 1.5 Flash input: $0.35 → $0.075 /1M −78%

Google's aggressive repricing made Flash the volume workhorse of the budget tier almost overnight.

Nov 2024
Claude Haiku tier: $0.25 → $0.80 /1M input +220%

The counter-example: prices rise too. Teams that hardcoded "Haiku = cheap" in their budgets found out from the invoice.

2024
Google Maps consumption model overhaul

SKU restructure changed effective per-load costs for most integrations — a classic "no announcement email" change caught by page monitoring.

Ongoing
Cloud egress fee movements (R2 zero-egress, EU portability rules)

Egress pricing is the most active battlefield in cloud pricing — and the least announced.

From launch (July 2026) every verified change on tracked providers gets logged here with exact old → new values.

Why this matters more than it sounds

Usage-based pricing means a small unit change multiplies across your entire volume, silently. A payment processor moving 2.9% → 3.1% takes 7% more of your margin on every sale. An SMS price up $0.001 is +13% at scale. And vendors know exactly how these changes read, which is why they land on pricing pages without an email announcement.

Catching the change on day one — instead of on next month's invoice — buys you four weeks of lead time: to renegotiate, to check the alternatives, or to model the new bill in the stack calculator before finance asks why costs jumped.
