Thinking on AI pricing, model selection, routing strategy, and building crypto-native developer tools.
Raw API keys are a liability. No names, no budgets, no revocation granularity. Here's how Cards fix every one of those problems — and why we think they're the right primitive for AI access management.
Most developers overpay for AI because they use one model for everything. A routing strategy using fast cheap models for simple tasks changes the math entirely.
We ran 200 prompts across coding, reasoning, creative writing, and summarization. Here's the breakdown and the routing rules we'd recommend.
Stripe requires a company, a bank account, and two weeks of KYC. Solana requires a wallet address. The tradeoffs were real — here's the honest breakdown.
You can now set rate limits per model group on each card. Cap Claude at 1000 requests/day on your dev card. Let production run unlimited. Shipped today.
