LLM Engineering FAQs

Common questions about hiring LLM engineers and building with Large Language Models.

What does an LLM engineer do?

LLM engineers specialize in working with Large Language Models like GPT-4, Claude, Gemini, and LLaMA. They fine-tune models on custom data, optimize prompts for specific tasks, build RAG (Retrieval-Augmented Generation) systems, integrate LLMs into applications, implement safety guardrails, optimize inference costs, and create custom LLM-powered features. They bridge the gap between raw AI capabilities and practical business applications.

What skills should an LLM engineer have?

Our LLM engineers have expertise in prompt engineering, model fine-tuning (LoRA, QLoRA, full fine-tuning), LLM APIs (OpenAI, Anthropic, Google), vector databases, embeddings, RAG architecture, LangChain/LlamaIndex, token optimization, context window management, output parsing, function calling, model evaluation, and cost optimization. They also understand transformer architecture, attention mechanisms, and latest LLM research.

Which LLMs do your engineers work with?

Our engineers have production experience with GPT-4, GPT-3.5, Claude (2 & 3), Google Gemini, LLaMA 2 & 3, Mistral, Mixtral, Falcon, MPT, open-source models, and custom fine-tuned variants. They can advise on model selection based on your use case, latency requirements, cost constraints, and data privacy needs.

Can LLM engineers fine-tune models on our proprietary data?

Yes, our LLM engineers specialize in fine-tuning models on proprietary datasets. They handle data preparation, annotation, training pipeline setup, hyperparameter tuning, evaluation, and deployment. They can fine-tune open-source models (LLaMA, Mistral) or use API-based fine-tuning (OpenAI, Anthropic) while ensuring data security and compliance.

How do LLM engineers optimize costs?

LLM engineers reduce costs by optimizing prompt length, implementing caching strategies, choosing appropriate models for tasks, batching requests, using smaller models for simple tasks, implementing rate limiting, leveraging open-source alternatives, and fine-tuning smaller models for specific use cases. Companies typically see 40-70% cost reduction after optimization.

What's the ROI of hiring an LLM engineer?

Companies hiring LLM engineers see 3-5x faster AI feature development, 50-70% reduction in LLM costs through optimization, improved output quality leading to 80%+ user satisfaction, faster time-to-market for AI products, and the ability to build competitive AI capabilities. One LLM engineer can replace dozens of GPT-4 API calls with fine-tuned, optimized solutions.
