AI for Insurance: Self-Hosted

Insurance AI workflows process large volumes of regulated personal data with high audit and explainability requirements. UK insurers face FCA + UK GDPR + Data Protection Act 2018 + Insurance Act 2015. Self-hosted on UK dedicated GPU is the cleanest path.

Workloads

• Claims processing: structured extraction from claim documents + automated triage
• Underwriting assistance: risk classification + premium suggestion
• Fraud detection: anomaly detection in claims + cross-reference patterns
• Customer support: policy Q&A grounded in policy documents
• Regulatory reporting: structured extraction from internal data for FCA reporting

Compliance

UK insurance regulatory frameworks:

• FCA Consumer Duty: AI decisions must serve customer interests; explainability required
• FCA SYSC 8: outsourcing rules — AI vendor management
• UK GDPR Article 22: automated decisions affecting consumers
• Insurance Act 2015: fair claims handling
• PCI-DSS: where payment card data flows

Self-hosted single-tenant infrastructure simplifies all of these vs hosted-API alternatives.

Stack

• UK dedicated GPU (4090 SMB / 5090 mid-tier)
• Mistral 7B / Llama 3.1 8B FP8 for routine; Mistral Small 3 24B AWQ for premium reasoning
• Structured-output JSON via vLLM guided decoding for claims extraction
• Per-decision audit: input + model output + confidence + final decision + human reviewer
• Bias-monitoring eval harness for underwriting fairness
• Claude / GPT-4o fallback for hardest novel cases

Verdict

For UK insurance AI, self-hosted on UK dedicated GPU is the right architecture. FCA Consumer Duty + GDPR + Insurance Act compliance all benefit from single-tenant + residency + auditability. The hybrid pattern (self-hosted bulk + frontier API fallback) is the production default.
