You can now store JSON values in Vercel Flags, extending the existing support for boolean, string, and number values. This allows you to collapse what used to take several related flags into a single feature flag.
For example, to A/B test how a different model performs, you can now define a single model flag. This allows you to manage one flag that serves the full object rather than managing ai_model, ai_temperature, and ai_max_tokens separately:
1// Variant A2{3 "id": "claude-sonnet-4-6",4 "temperature": 0.7, 5 "maxTokens": 1024,6 "systemPrompt": "You are a helpful shopping assistant."7}8
9// Variant B10{11 "id": "claude-opus-4-6",12 "temperature": 0.8, 13 "maxTokens": 2048,14 "systemPrompt": "You help with shopping."15}A feature flag holding JSON configuration in its variants
Use Vercel Flags to progressively route traffic to a new model, A/B test, or quickly switch models in case a provider is having issues.
