Our Data Labeling for Coding LLMs Workflow
Follow our expert-driven process to solve coding tasks at scale.
We begin by setting up the project team, including both internal and vendor teams, and then assign tasks based on the required programming languages. We conduct training sessions for both our delivery team and vendors to clarify guidelines and answer questions. Finally, we hold meetings with both teams to align on the execution methodology.
We carry out trial tasks and deliver them to the client. After receiving feedback, we organize follow-up meetings with internal and external delivery teams. Based on the results and feedback, we update the guidelines to address new scenarios or edge cases identified during this phase.
- If a batch achieves a ≥90% acceptance rate, the entire batch is approved.
- If a batch has a ≥90% rejection rate, the entire batch must be reworked and resubmitted.
We report externally caused rejections (unclear descriptions, hidden requirements) to the client for clarification. Additionally, we meet every other day to address and resolve internal errors discovered during the execution process.

FAQs about Fine-tuning LLMs for Coding and Programming
What is fine-tuning for LLMs in coding?
Fine-tuning is the process of taking a pre-trained large language model and training it further on a curated dataset of source code or code-related tasks. This allows the model to specialize in programming-specific functions such as code generation, debugging, or documentation, etc.
What is RLHF?
Reinforcement Learning from Human Feedback (RLHF) is a method used to improve LLMs by incorporating human preferences. Following initial training, human feedback is integrated into this process to further train LLMs for better response performance.
What is the difference between SFT and RLHF?
Supervised Fine-tuning (SFT) involves training LLMs using labeled data to teach task-specific behavior. RLHF then follows, utilizing human feedback and reinforcement learning to refine outputs and align them with human values. SFT teaches what to say, while RLHF refines how to say it.
How does fine-tuning differ from prompt engineering?
Fine-tuning uses specific datasets to adjust an LLM’s parameters for specialized coding tasks. In contrast, prompt engineering focuses on crafting better input prompts to guide the model’s responses, without changing the model itself.
What types of coding tasks can fine-tuned coding LLMs perform?
Fine-tuned LLMs can generate code, provide answers, create dialogues, and evaluate logic. They can also translate between languages, generate documentation, and assist with DevOps scripts. When trained on specific codebases, they master domain-specific development tasks.
What are the benefits of fine-tuning a code-specific LLM?
Fine-tuned coding LLMs improve accuracy, reduce errors, and better understand specific languages or codebases. This directly enhances the performance of AI coding agents, AI coding assistant tools, AI code generators, and other best AI coding tools, delivering more relevant suggestions and aligning outputs with internal coding standards.
