`Vercel Flags` now supports JSON values

Related config can now live in one flag instead of being split across several. That makes model rollouts, A/B tests, and provider failover less brittle, so it is worth using if Vercel Flags is already in the stack.

[ KEY POINTS ]

A single JSON flag can replace separate boolean, string, and number flags tied to the same feature config.
The example is model experimentation: one ai_model object can hold settings that previously needed ai_model, ai_temperature, and ai_max_tokens.
This fits progressive traffic routing to a new model, controlled A/B tests, and fast provider switching during outages.

`RevenueCat` Adds Flexible Discounts for Web Billing
60radar
RevenueCatSubscription billing infra — unified app and web subscriptions
Web subscriptions can now use percentage discounts, promo codes, and win-back offers. Useful for churn recovery and price testing without wiring discount logic yourself.
- Percentage-off discounts and promo codes now apply to RevenueCat web subscribers, reducing custom billing work.
- Win-back offers target cancelled or lapsed users. That gives churn recovery a built-in path instead of ad hoc email-only campaigns.
- The scope is web billing, not App Store pricing. Best fit is a paid web checkout where discount tests can move quickly.

Stripe Link CLIPayment CLI — one-time credentials from a Link wallet
Agents can receive one-time payment credentials from a Link wallet without storing raw card data. Useful for agentic commerce experiments; production value depends on merchant support.
- Issues one-time credentials from a Link wallet, so agents can complete purchases without keeping actual card details.
- Supports two credential types: broadly usable virtual card PAN and an S... option based on Machine Payment Protocols.
- This is payment infrastructure, not just automation. It opens tests for delegated checkout, procurement bots, and agent-run SaaS workflows.

`AI Gateway` adds request-time provider ranking controls

AI GatewayAI routing service — failover across model providers
Routing can now optimize on price, first-token latency, or throughput at request time instead of Vercel's blended default. Useful when one model has many providers and the cheapest or fastest route materially changes margin or UX.
- Set sort on providerOptions.gateway to 'cost', 'ttft', or 'tps' depending on whether margin, snappiness, or long-output speed matters most.
- Ranking is computed at request time, so newly added providers, price changes, and observed latency shifts flow through without code changes.
- Fallback is strict: providers are attempted in sorted order, and the next one is used only if the higher-ranked provider is unavailable.
- sort works with Zero Data Retention filtering and with order; pinned providers stay first, then the rest follow the chosen ranking.
- Each response exposes routing metadata with a sort block showing candidates, metric values, attempt order, and health-based deprioritization for debugging.
