Claude Fable 5.2 in Europe: where you can run it and what is stored

Anthropic's data residency page lists Claude Fable 5.2 among the models that take the inference_geo parameter. The values are global, where "inference may run in any available geography for optimal performance and availability", and us, where "inference runs only in US-based infrastructure". The page states: "Only "us" and "global" are available." For data at rest it says: "Currently, "us" is the only available workspace geo."

On retention, Anthropic's API and data retention page says Claude Fable 5.2 and the other Fable and Mythos models "require 30-day data retention and are not available under ZDR unless expressly authorized by Anthropic." An organization with a ZDR arrangement can turn on 30-day retention for one workspace, and the other workspaces keep zero data retention.

The Bedrock model card lists two inference IDs: the geo profile us.anthropic.claude-fable-5-2 and the global profile global.anthropic.claude-fable-5-2. In-Region inference is not supported in any Region. In Frankfurt, Ireland, Stockholm, Paris, Milan, Spain, Zurich and London the card marks Geo as not supported and Global as supported. AWS describes Global Cross-Region inference as routing "anywhere worldwide when there are no residency constraints".

On retention, the card says: "To use this model, you must opt in to AWS review by setting your data retention mode to aws_review." AWS's launch post of 9 November 2026 adds that Anthropic has designated Fable 5.2 a covered model "which require[s] data retention for safety monitoring", and that "until Enterprise Frontier Safeguards is available, eligible customers can use Fable 5.2 with zero data retention." AWS gives no end date for that exception in the post.

Google's Fable 5.2 model page lists the model as generally available on three endpoints: us (US multi-region), eu (Europe multi-region) and global. It lists no single Europe region such as europe-west1.

The same page says: "All prompts and responses are stored for up to 30 days for the sole purpose of monitoring for potential abuse." So the eu endpoint answers where Fable 5.2 is processed, and a company still has to record that storage period in its data protection impact assessment.

Microsoft's Claude in Foundry page lists claude-fable-5-2 as "Hosted on Anthropic infrastructure: Preview". Microsoft describes that version as models that "run on Anthropic's infrastructure (outside of Azure)". Global Standard covers all Claude models. Data Zone Standard is offered in the US only, for Azure-hosted Claude models, and Fable 5.2 is not on that list.

For Foundry, Anthropic's retention page names Anthropic as the data processor, and it says the 30-day retention requirement "applies wherever Covered Models are offered".

OpenRouter. Its model page says: "anthropic/claude-fable-5.2 is not currently available through EU in-region routing."

Vercel AI Gateway. Its changelog of 9 November 2026 says: "Anthropic does not support Zero Data Retention for the model. Prompts and completions are retained for 30 days and are not used to train Claude." With team ZDR on, "AI Gateway returns an error instead of sending the request to Fable 5.2."

If Fable 5.2 has to be processed in Europe: Vertex AI's eu endpoint is the only Europe option any of the four platforms lists. Plan for Google's 30-day abuse-monitoring storage and record it.

If zero data retention is a hard requirement: Bedrock offers it to eligible customers until Enterprise Frontier Safeguards is available, through the us. or global. profiles, which are not in Europe. The Anthropic API needs Anthropic's express authorization.

If both are required: none of the four platforms lists Fable 5.2 with processing in Europe and zero data retention together. For that workload, use a Claude model that is served in Europe, such as Claude Opus 5.5, Sonnet 5.5 or Haiku 5.5.

Standard Compute does not currently offer Claude Fable 5.2. It is one gateway to frontier and open-source models, and for Claude processed in Europe it serves Claude Opus 5.5, Sonnet 5.5 and Haiku 5.5 through Google Vertex AI and Amazon Bedrock in Ireland.

Set a Europe rule for your company, a team or a single key, and every request, including retries and fallbacks, is served only by approved European inference endpoints. If no European endpoint can serve it, the request is refused before your prompt is sent. Our EU gateway terminates TLS and runs in Finland, and your account data is stored in Frankfurt.

Turn on zero data retention for your company, a team or a key, and every request is routed only to inference endpoints that commit to keeping no copy of your data. Sign our Data Processing Agreement in the dashboard in minutes. It commits us to no training on your data, no retention of your content, and breach notification within 72 hours.
