Claude Fable 5 reactivated in AI Gateway

July 1, 2026

Anthropic’s Claude Fable 5 model is once again available through Netlify’s AI Gateway with zero configuration required.

Use the Anthropic SDK directly in your Netlify Functions without managing API keys or authentication. The AI Gateway handles everything automatically. Here’s an example using the Claude Fable 5 model:

import Anthropic from '@anthropic-ai/sdk';
export default async () => {
const anthropic = new Anthropic();
const response = await anthropic.messages.create({
model: 'claude-fable-5',
max_tokens: 4096,
messages: [
{
role: 'user',
content: 'How can AI improve my coding?'
}
]
});
return new Response(JSON.stringify(response), {
headers: { 'Content-Type': 'application/json' }
});
};

Claude Fable 5 is available for all Function types. You get automatic access to Netlify’s caching, rate limiting, and authentication infrastructure.
