Frequently Asked Questions

Common questions about hiring a Generative AI Specialist

A Generative AI Specialist is an AI engineer who focuses on Large Language Models (LLMs), text-to-image systems, and AI content generation. They build applications using models like GPT-5.5, Claude Opus 4.7, Gemini 3.1 Pro, and latest Llama models, implement RAG systems, fine-tune models, and develop AI agents for enterprise automation.

Generative AI Specialist rates range from $50-$150/hour depending on expertise and project complexity. Likhon offers competitive rates from Bangladesh with enterprise-grade delivery. Project-based pricing: RAG systems ($5,000+), AI Agents ($3,000+), LLM fine-tuning ($2,500+), and Voice AI ($4,000+). Contact for a custom quote.

GPT-5.5 (OpenAI) is strong for coding and complex reasoning. Claude Opus 4.7 (Anthropic) is excellent for deep analysis and long-context writing. Gemini 3.1 Pro (Google) is strong for multimodal and Google ecosystem workflows. Likhon helps you choose the right model or implement multi-model strategies for optimal results.

RAG (Retrieval Augmented Generation) lets AI answer questions from your private documents without expensive fine-tuning. You need RAG if you have internal knowledge bases, documentation, or data that LLMs don't know about. RAG dramatically reduces hallucinations and enables enterprise knowledge search.

Yes, Likhon specializes in LLM fine-tuning using LoRA, QLoRA, and full-parameter methods. Fine-tuning is ideal when you need the model to adopt a specific style, learn domain terminology, or perform specialized tasks. Projects typically take 2-4 weeks with production deployment included. Learn more about LLM fine-tuning →

AI Agents are autonomous systems that can reason, plan, and execute multi-step tasks. Unlike simple chatbots, agents can use tools, call APIs, browse the web, and complete complex workflows. Likhon builds agents with LangChain, CrewAI, and Google ADK for customer service automation, research, and business process automation.

Yes, Likhon has deep expertise in both proprietary (GPT-5.5, Claude Opus 4.7, Gemini 3.1 Pro) and open-source model families (latest Llama, Mistral, DeepSeek, Qwen). Open-source models are ideal for data privacy, cost optimization, and on-premise deployments. Self-hosted solutions available on your infrastructure.

Likhon has delivered Gen AI projects across FinTech (fraud detection, document processing), Healthcare (clinical assistants, medical transcription), E-commerce (product recommendations, customer service), Legal (contract analysis, research), and Manufacturing (predictive maintenance, quality control).
