What Separates a Production GenAI Developer From a Prototype
| Concern | What our developers do |
|---|---|
| Accuracy | Build an evaluation set from real queries and score every release |
| Hallucinations | Ground answers in retrieved data, require citations, and add "not found" fallbacks |
| Cost | Route easy tasks to smaller models; use caching, prompt trimming and batch processing |
| Latency | Streaming, smaller context windows, parallel retrieval |
| Security | Treat retrieved and user content as data, never as instructions; limit tool permissions |
| Privacy | Zero-retention API terms or private model endpoints; PII redaction |
| Governance | Logging, transparency notices and documentation to support obligations such as the EU AI Act |

Frequently Asked Questions
What does a generative AI developer do?
<p>A generative AI developer builds applications powered by large language models and other generative models, such as chat assistants, RAG knowledge systems, content generators and document AI, and makes them accurate, secure and cost-efficient in production.</p>
How much does it cost to hire a generative AI developer?
<p>Dedicated generative AI developers from PerfectionGeeks start from $55 per hour, or about $8,800 per month full-time. Model API or GPU hosting costs are billed separately by the provider.</p>
What skills should a generative AI developer have?
<p>Key skills include working with GPT, Claude, Gemini and open-weight models; prompt and context engineering; RAG with vector databases; LangChain or LlamaIndex; fine-tuning with LoRA; evaluation methods; prompt-injection defense; and Python or TypeScript back-end development.</p>
What is the difference between a generative AI developer and an AI developer?
<p>A generative AI developer specializes in LLM and content-generation systems: RAG, prompting, fine-tuning and guardrails. An AI developer covers a broader range of AI features, including computer vision, predictive models and integrations.</p>
Can a generative AI developer fine-tune a model on my data?
<p>Yes. Our GenAI developers fine-tune open-weight models such as Llama or Mistral with LoRA or QLoRA when evaluation shows prompting and RAG aren't enough, and can deploy them privately in your cloud.</p>
How do your developers prevent hallucinations?
<p>They ground answers in retrieved company data, require citations, add confidence thresholds and fallback responses, and test every release against an evaluation set of real questions.</p>
Is my data safe with a generative AI developer?
<p>Yes. Developers sign NDAs, use zero-retention model APIs or private endpoints, redact personal data before it reaches a model, and work under your access controls.</p>
How quickly can I hire a generative AI developer?
<p>You can typically review matched GenAI developer profiles within days and have a developer start within about one week.</p>
Who owns the prompts, data and models?
<p>You do. All code, prompts, evaluation datasets, fine-tuned weights and intellectual property created for you belong to you.</p>
Should I hire a GenAI developer or a GenAI development company?
<p>Hire a dedicated GenAI developer when you have a product team and want extra GenAI capacity. Choose a development company for an end-to-end project with fixed scope. PerfectionGeeks offers both.</p>
