InfoAFYA LLaMA 3 8B – GGUF Variant

Model: dpeke/infoafya-8b-v1.0.gguf
Architecture: LLaMA 3.1 (8B)
Format: GGUF (optimized for llama.cpp and compatible runtimes)

---

Model Summary

The InfoAFYA LLaMA 3.1 8B – GGUF Variant is a behaviorally informed health assistant model fine-tuned to provide step-by-step, empathetic, and culturally grounded health communication. It is designed for low-resource settings in Kenya and other LMICs to help caregivers, youth, and community health volunteers (CHVs) navigate health challenges, with a focus on Sickle Cell Disease (SCD) and related health literacy needs.

This GGUF variant is optimized for deployment with llama.cpp and compatible backends such as Ollama, GPT4All, llama-cpp-python, and other lightweight inference stacks.

Example SMS Health Messaging

The table below shows how behavior change techniques (BCTs) were applied to generate health messages during fine-tuning:

Health Literacy Level	Health Messaging Theme & Intent	Behavior Change Techniques (BCTs)	Behavior Change Objectives	Example Prompts	Generated SMS Samples
Functional	Understanding SCD, genetics, symptoms, clinical management	5.1 Info about consequences 13.2 Framing 6.1 Demonstration 9.1 Credible source	Raise awareness, reduce stigma, reframe beliefs, highlight resilience, use trusted voices	Create an SMS that informs the community about how SCD affects daily life and encourages respect.	1. Living with Sickle Cell Disease (SCD) can be challenging! Children with SCD face constant pain, but they also need your understanding and support. 2. SCD doesn't define you! People living with SCD are superheroes who adapt and thrive. 3. Did you know? SCD is passed down genetically. It's NOT a curse or anyone's fault.
Interactive	Routine clinics, compliance, nutrition, hydration, HCW interaction	4.1 Instructions 7.1 Prompts/cues 1.2 Problem Solving 1.4 Action Planning 8.1 Practice	Guide patients on care, provide reminders, suggest affordable coping strategies, develop health plans, practice disclosure	Generate an SMS that guides patients to prepare for a clinic visit.	4. Remember: regular clinic visits are key to managing SCD! Stay hydrated, share your symptoms, and follow up with your doctor. 5. Don't forget! Taking your SCD meds on time & attending appointments keeps you active. 6. Need hydration on a budget? Carry water from home or refill affordably.
Critical	Health rights, advocacy, school/workplace awareness	10.1 Incentives 6.2 Social Comparison 3.1 Social Support	Share info on financial support, encourage peer/staff networks, showcase successful role models	Write an SMS that explains how SHIF coverage helps families living with SCD.	11. Live fearlessly! SHIF coverage helps families get meds, check-ups & emergency care. 12. You can succeed in life with SCD – your dreams are valid. 13. You're not alone! Share your journey with peers and advocates who understand.
