Questions

How does custom data help agents?

Fine-tuning agents with your domain data unlocks true expertise and efficiency that generic models can’t match:


  • Expert Knowledge: A fine-tuned agent knows your terminology, standards, and nuances. It understands context that generic models might miss, resulting in responses that sound like they come from a seasoned expert in your field.
  • Accuracy & Relevance: Custom-tuned models deliver precise answers and solutions. By training on curated examples, the model aligns with your tasks - reducing errors, off-topic responses, and hallucinations compared to a generic model.
  • Consistency & Compliance: Your fine-tuned agent will follow your organization’s guidelines, tone, and regulatory requirements. This ensures consistent, compliant outputs, which is critical in our increasingly regulated environment.
  • Operational Efficiency: With a domain-trained agent, you spend less time on prompt engineering or manual result filtering. The agent can more reliably “get it right” the first time, accelerating workflows from customer support to data analysis.

What Is RLHF (Reinforcement Learning from Human Feedback)?

LLms don’t stop learning after fine-tuning. For critical, high-stakes use cases - where accuracy, tone, and alignment truly matter. We apply Reinforcement Learning from Human Feedback (RLHF) as the final stage in the training pipeline.


RLHF is a process where human reviewers score the model’s outputs, and those scores are used to optimize the model’s behavior using reinforcement learning techniques. It’s how models like ChatGPT have become safer, more useful, and better aligned with human intent.


HOW RLHF ENHANCES LLM OUTPUT QUALITY


  • Human-Centric Alignment: RLHF ensures that outputs reflect not just what’s statistically likely, but what humans actually consider helpful, relevant, and safe.
  • Contextual Reasoning: It improves the model’s ability to maintain tone, follow policies, or prioritize one type of response over another - critical for industries like medical or automotive.
  • Reduced Hallucinations: By evaluating model completions across many edge cases, RLHF can drastically reduce the occurrence of fabricated facts or irrelevant outputs.

When to Use PPO and RLHF Over Traditional Fine-Tuning?

Traditional supervised fine-tuning is often sufficient for many enterprise LLM use cases. However, some workflows require more control, precision, and behavior shaping—that’s where Proximal Policy Optimization (PPO) and RLHF come in.


Use PPO + RLHF when:

  • You need the model to follow complex, multi-turn instructions
  • Your agents need to weigh multiple outcomes, prioritize based on context, or enforce ethical or regulatory rules
  • ROutput behavior must adapt over time based on user feedback or new policies

This approach is especially valuable in fields like autonomous support agents, clinical documentation, or regulatory compliance where human expectations shift rapidly, and outputs must be carefully aligned.

Popular models to work with

Whether you’re building on open-source foundations, proprietary APIs, or hybrid stacks, we can help improve your agent. Our domain specialists and data teams adapt the training pipeline to suit each model’s strengths and deployment requirements.


LLaMA


Meta’s LLaMA (Large Language Model Meta AI) models are highly efficient and optimized for fine-tuning across diverse tasks. With variants like LLaMA 2 and the upcoming LLaMA 3, they offer strong performance and are especially suitable for on-premise deployments, data-sensitive environments, and use cases requiring full model control. We help businesses customize and deploy LLaMA-based models with security, compliance, and scalability in mind.


GPT (OpenAI)


GPT models are the most well-known LLMs and are commonly accessed through OpenAI’s API or via platforms like Azure OpenAI. They excel at general-purpose tasks and integrate well with customer support agents, content creation, and complex reasoning workflows. Our team supports both prompt-based optimization and embedding-based retrieval augmentation, as well as supervised fine-tuning on internal knowledge bases when available.


Falcon


Developed by the Technology Innovation Institute (TII), Falcon models are powerful open-source alternatives designed for cost-efficient inference and scalable fine-tuning. They fit the public sector, academic research, and any application that benefits from open governance and transparency. We assist teams in training and deploying Falcon models in production-grade pipelines with human-in-the-loop QA.


Mistral


Mistral’s models (like Mistral 7B and Mixtral) are lightweight, high-performance open-source LLMs that excel in edge computing and low-latency inference. These models are ideal for businesses that need flexible, fast models with strong multitask capabilities. Our fine-tuning services make them even more efficient and context-aware for niche domains - especially where GPU constraints or response speed are critical.


Claude (Anthropic)


Claude, developed by Anthropic, is designed with a strong emphasis on harmlessness, honesty, and helpfulness—making it a powerful choice for applications where alignment and ethical safety are critical. It’s widely used in enterprise chatbots, knowledge management, and moderation tasks, especially when natural, conversational tone and safety guarantees are a priority. We support organizations in tailoring Claude’s behavior through structured prompt strategies, fine-tuning via APIs, and human-in-the-loop validation for compliance-heavy industries.


Open Source LLMs


We also work with a wide range of other open-source models including Vicuna, Zephyr, OpenChat, and Instruct-tuned derivatives. These are often used in experimental applications, sandbox environments, or for organizations building fully self-hosted AI infrastructure. Our pipeline allows for training, validation, and deployment of these models with full human feedback integration, ensuring their outputs meet enterprise-grade quality.
