LLM price-change alert feed: track when OpenAI, Anthropic, Google or any AI provider reprices GPT, Claude, Gemini or any model's inference cost per token — old vs new price, percent delta, when it happened, plus newly launched and removed models. Structured JSON diffed from hourly snapshots; ideal for cost monitoring, repricing triggers, and AI market intelligence.
