| Third-party gateways | ❌ Not recommended | Sites like OpenRouter may offer trial credits occasionally, but there is no strong evidence of a reliable, permanent free credit for Claude Fable 5 specifically. Stick to official platforms. |
Start with Claude Platform if you want the fastest direct access to Fable 5. The credit is small but immediate and simple to use.
If you want more free compute, open a Google Cloud Free Trial and enable Vertex AI with Claude models. The $300 credit over 90 days gives you the longest and most generous testing window.
If you have an existing AWS account or can join AWS Activate, try Amazon Bedrock after confirming your specific credit (new account, Activate, etc.) covers Bedrock and third-party model usage.
Use Microsoft Foundry only if you have an enterprise Azure subscription (e.g., EA or MCA-E) where Marketplace billing is managed and you are not relying on startup or free-trial credits.
Bottom line: Google Cloud Vertex AI is your best bet for a large, reliable free credit ($300 for 90 days). Claude Platform is your fastest option (small instant credit). Do not enter API keys or personal information into unknown 'free Claude' websites — only use official platforms with transparent pricing.
