EdTech AI workloads — adaptive tutoring, content generation, marking assistance, student feedback — have specific characteristics: high volume per student, age-of-user data sensitivity, often public-sector procurement (DfE / state education). Self-hosted economics are favourable; data residency simplifies safeguarding compliance.
Stack: Llama 3.1 8B FP8 (general tutoring) or Qwen 2.5 7B (multilingual) on UK 4090 + BGE-large + Qdrant for curriculum / textbook corpus. Custom safety fine-tunes for child-appropriate output. UK residency for DfE / GDPR Art 8 compliance. Hosted-API fallback for hardest pedagogy questions. £500-2K/mo SMB EdTech infrastructure.
Workloads
- Adaptive tutoring: per-student conversation tailored to level + curriculum
- Question generation: from curriculum content for practice + assessment
- Marking assistance: structured feedback on essays / exercises
- Content generation: lesson plans, worksheets, slide decks for teachers
- Translation / accessibility: multi-language access to materials
Models
- Llama 3.1 8B: general English tutoring; fine-tune for age-appropriate output
- Qwen 2.5 7B: multilingual EdTech (especially for international school chains)
- Mistral 7B: English; alternative
- R1-Distill-Qwen-7B: better for maths / step-by-step explanation
- Custom safety LoRA: trained on age-appropriate examples; ~£10 of GPU time
Student data residency
For UK education, three regulatory frameworks matter:
- UK GDPR Article 8: child consent threshold (13 in UK)
- DfE Keeping Children Safe in Education: vetting AI tools for safeguarding
- DfE data security guidance: UK residency strongly preferred for state-funded schools
- Subject Access Requests: GDPR right of access — per-student log accessibility matters
Self-hosted in UK dedicated GPU simplifies all of these dramatically vs hosted-API alternatives.
Verdict
For UK EdTech serving state-funded schools, self-hosted on UK dedicated GPU is the right architecture. The DfE residency + safeguarding alignment is decisive; the cost economics scale well. Pair with custom safety LoRAs and hosted-API fallback for premium pedagogy needs.
Bottom line
UK self-hosted = DfE-compliant EdTech. See UK residency.
