Scope

Prompt Engineering Services We Deliver

Prompt Design & Optimization

We craft effective, structured prompts tailored to use cases such as chatbots, classification systems, summarisation tools, and autonomous agents — optimised for accuracy, consistency, and cost efficiency.

Prompt Frameworks & Libraries

Our team creates reusable, modular prompt libraries that support consistency and scalability across different models, teams, and product lines.

Prompt Evaluation & A/B Testing

We perform controlled testing and benchmarking of prompt variants to optimise for output accuracy, response consistency, latency, and API cost.

Model-Specific Prompting

Our specialists engineer prompts for top-performing LLMs including OpenAI’s GPT-4, Anthropic’s Claude, Google Gemini, Mistral, and Meta LLaMA — ensuring each model operates at peak effectiveness.

RAG & Hybrid Systems Co-Design

We align prompt engineering with retrieval systems, context augmentation, and multi-model routing to deliver robust, grounded, and factually accurate outputs.

Prompt-to-Finetune Strategy Consulting

We advise on when to transition from prompt engineering to dataset design, fine-tuning, or instruct-tuning workflows for deeper model specialisation.

Process

Our Prompt Engineering Process

With extensive software and AI development experience, our structured approach ensures every engagement — from experimentation to deployment — is efficient, robust, and tailored to your use case.

  • 01

    Discovery & Assessment

    We start by understanding your business needs, product goals, and existing systems. We assess where LLMs can add value and map out prompt-driven opportunities aligned with your objectives.

  • 02

    Proposal & Planning

    Our team prepares a clear project scope, resource plan, model selection, and prompt development timeline tailored to your specific requirements.

  • 03

    Development & Testing

    We craft, evaluate, and integrate prompts through synthetic evaluation, output scoring, and human feedback loops to ensure production readiness and consistent performance.

  • 04

    Integration & Scaling

    Once validated, we integrate prompts into your applications, APIs, or agent systems. We also implement logging, monitoring, and iteration pipelines to support continuous improvement at scale.

Cost

What do prompt engineering services cost?

The cost of prompt engineering depends on model usage, integration complexity, and experimentation cycles. Dev House Austria provides senior-level expertise at competitive rates tailored to your engagement model. Key factors that influence pricing:

  • Use case complexity
  • Target model(s) and deployment stack
  • Volume of prompt variants
  • Integration depth (API-level vs. product-level)
  • Prompt testing/evaluation effort
  • Team composition and seniority

FAQs

  • Answer: Prompt engineering is the practice of designing and optimising inputs to LLMs to control their output, ensure reliability, and align results with your business objectives. It transforms AI from an experimental technology into a production-grade tool that delivers consistent, measurable value.

  • Answer: We support major LLMs including GPT-4, Claude 3, Gemini, Mistral, and open-source models like LLaMA. We also help with multi-model orchestration and fallback strategies to ensure reliability and cost optimisation.

  • Answer: Yes. We specialise in embedding LLM capabilities into web, mobile, and internal tools using modern frameworks and production APIs — ensuring seamless integration with your existing architecture.

  • Answer: Absolutely. We offer team augmentation services, embedding our prompt engineers directly into your product or ML teams for sustained impact and knowledge transfer.

  • Answer: Prompting uses existing models to solve problems via well-structured inputs, while fine-tuning customises a model's internal behaviour using training data. We advise on when to use each approach — or a combination of both — based on your use case, budget, and performance requirements.
