AI Fine-Tuning
Custom LLMs trained on your data and domain expertise
Generic LLMs are general-purpose. Fine-tuned models are competitive weapons. We help you collect, curate, and use your proprietary data to train models that speak your industry's language, follow your brand's style, and make decisions aligned with your business logic — at a fraction of the inference cost of the frontier models.
Our AI Fine-Tuning Capabilities
Every engagement is built around your specific goals — here's the full scope of what we bring to the table.
Training Data Curation
Collection, cleaning, deduplication, and quality filtering of your proprietary datasets. The quality of your fine-tune is only as good as the data that goes in.
Supervised Fine-Tuning (SFT)
Full fine-tuning and parameter-efficient methods (LoRA, QLoRA) on base models like Llama 3, Mistral, and Phi-3 — or via the OpenAI and Anthropic fine-tuning APIs.
RLHF & Preference Optimisation
Reinforcement learning from human feedback and Direct Preference Optimisation (DPO) to align model behaviour with your quality standards.
Evaluation & Benchmarking
Domain-specific evaluation datasets, automated benchmarks, and human eval processes to measure whether your fine-tune actually outperforms the base model on your tasks.
Model Hosting & Inference
Deploying your fine-tuned model on cost-efficient GPU infrastructure with vLLM or TGI inference servers — up to 10× cheaper per token vs. frontier API calls.
Continuous Improvement
Feedback loops, active learning pipelines, and periodic re-training so your model improves as you accumulate more data from production.
Our Process
A structured, transparent workflow so you always know what's happening and what comes next.
Data Audit
We assess your existing data sources — support tickets, documents, code, conversations — for volume, quality, and fine-tuning suitability.
Task Definition & Baseline
Define the specific behaviour you want to improve, create a benchmark dataset, and measure the base model's current performance.
Data Preparation
Formatting data into training pairs (prompt → completion), applying quality filters, and splitting into train/validation/test sets.
Fine-Tuning Runs
Iterative training with hyperparameter optimisation. Multiple checkpoints evaluated against the benchmark to select the best-performing model.
Deploy & Monitor
Model served on your infrastructure or hosted API, with latency monitoring, cost tracking, and drift detection in production.
Tools & Technologies
We use best-in-class tools and frameworks — chosen for your project, not for familiarity.
What You Receive
Everything you need to go live and grow — documented, handed over, and supported.
Common Questions
For supervised fine-tuning, 500–5,000 high-quality examples often produce strong results. For behaviour alignment, even 100 carefully crafted preference pairs can make a meaningful difference.
Use RAG when your knowledge base changes frequently. Use fine-tuning to change model behaviour, style, or reasoning patterns. Many production systems use both together.
You do. The trained weights are your intellectual property and are delivered to your infrastructure. We sign an IP assignment agreement before any training begins.
Yes. We can run the entire training pipeline in your cloud environment (AWS, GCP, Azure) so your data never leaves your infrastructure.
Llama 3 (8B, 70B), Mistral 7B, Phi-3, Qwen 2, and most open-weight models on Hugging Face. For hosted APIs, OpenAI GPT-4o mini and GPT-3.5 fine-tuning is also available.
