v1.3.0 — Cloudflare Workers AI vision support

Added

• Cloudflare Workers AI vision support — CloudflareProvider now accepts request.images and routes to vision-capable models. Previously image data was silently dropped on the CF path.
• Three new CF vision models:
  • @cf/google/gemma-4-26b-a4b-it — 256K context, vision + function calling + reasoning
  • @cf/meta/llama-4-scout-17b-16e-instruct — natively multimodal, tool calling
  • @cf/meta/llama-3.2-11b-vision-instruct — image understanding
• CloudflareProvider.supportsVision = true — factory's analyzeImage now dispatches to CF when configured.
• Factory default vision fallback — getDefaultVisionModel() falls back to @cf/google/gemma-4-26b-a4b-it when neither Anthropic nor OpenAI is configured, enabling CF-only deployments to use analyzeImage().

Changed

• Images are passed to CF using the OpenAI-compatible image_url content-part shape (base64 data URIs). HTTP image URLs throw a helpful ConfigurationError — fetch the image and pass bytes in image.data.
• Attempting request.images on a non-vision CF model throws a ConfigurationError naming the vision-capable alternatives.

Usage

factory.analyzeImage({
  image: { data: base64, mimeType: 'image/jpeg' },
  prompt: 'Extract recipe data',
  model: '@cf/google/gemma-4-26b-a4b-it',
});
