A Powerful Performer
How to Train an LLM
The LLM lifecycle begins with curating a diverse dataset to equip your model with relevant language and domain expertise. Developing foundation models and training LLMs for multi-modal applications involves processing vast amounts of raw data, including text, images, videos, and audio, to help the model understand human language and various media types effectively.
LLM Fine Tuning
Once your foundation model is built, further training is required to fine tune your LLM. Optimize model performance for specific tasks and use cases by introducing labelled datasets and carefully engineered prompts curated to the target applications.

Guide to CoT reasoning for LLMs featuring an expert case study on how Appen built a mathematical reasoning dataset for a leading technology company.
LLM Benchmarking & Evaluation
LLM’s should be evaluated continuously to improve the accuracy of the model and minimize AI hallucinations. Create quality assurance standards for your LLM and leverage human expertise to evaluate your model against those guidelines.

LLM red teaming & model safety
Leverage Appen’s red teaming crowd to proactively identify vulnerabilities and ensure the safety and security of your LLM across diverse applications.
Conduct open-ended or targeted red teaming tasks such as:
- Adversarial attacks
- Harms categories (toxicity, bias, privacy, etc.)
- Multi-turn scenario-based testing
- Guardrails testing
- Moderation and annotation of generated content
Retrieval-Augmented Generation (RAG)
Tailor your model to specific domains and generate more precise and contextually relevant responses by introducing a broader, external knowledge base.
Retrieval-Augmented Generation (RAG) data services include:
- Data Preparation: Collect, annotate and curate datasets for your unique use case.
- Prompt Dataset Creation: Generate effective prompts for effective model training.
- Evaluation and A/B testing: Compare performance across models and refine outputs.
- Red Teaming: Stress-test your model to preemptively identify and resolve vulnerabilities.
