End-to-end model ownership

From raw data to production API — WOYOU AI handles every stage of custom LLM development so your team ships faster.

Domain Fine-Tuning

Adapt Llama 3, Mistral, Gemma 2, or GPT-4 to your domain, vocabulary, and reasoning style using SFT and RLHF. Outperform general-purpose models on your specific tasks — at a fraction of inference cost.

Pre-training from Scratch

Build a fully proprietary transformer on your corpus. Custom tokenizer, architecture choices, and full IP ownership — no foundation model dependencies.

Data Pipeline & Curation

Transform raw documents, databases, and PDFs into high-quality training sets. Deduplication, PII scrubbing, quality scoring, and synthetic augmentation.

Quantization & Speed

Cut inference cost by 60–80% via INT4/INT8 quantization, model pruning, speculative decoding, and flash-attention optimization — without quality loss.

Evaluation & Red-Teaming

Rigorous benchmarks, adversarial probing, hallucination audits, and safety evals aligned to your use case and regulatory requirements (HIPAA, SOC 2).

Deployment & API

Managed deployment on your cloud (AWS, GCP, Azure) or on-premise. OpenAI-compatible REST API, autoscaling, observability dashboards, and SLA-backed uptime.

From raw data to
deployed model

Structured, transparent, and collaborative — you stay in the loop at every stage.

  1. Discovery & Data Audit

    We assess your dataset quality, define success metrics, and align on model architecture. You receive a detailed scope document with fixed deliverables before work begins.

  2. Data Preparation

    Automated pipelines clean, deduplicate, and format your data. We handle private document parsing, schema normalization, quality scoring, and synthetic augmentation.

  3. Training & Iteration

    Distributed training on A100/H100 clusters with real-time dashboards. You get live loss curves, eval metrics, and a shared workspace for feedback across iteration cycles.

  4. Deploy & Monitor

    Production-grade inference deployment with autoscaling, latency monitoring, drift detection, and optional scheduled re-training pipelines to keep your model current.

What our clients say

"WOYOU fine-tuned our internal knowledge base into a model that outperforms GPT-4 on our legal document tasks — at a fraction of the inference cost."
Sarah R.
CTO, LexAutomata
"Their data curation pipeline cleaned 80 TB of clinical records into training-ready datasets. The resulting model passed our clinical validation benchmarks on first pass."
Dr. Daniel K.
Head of AI, MedCore Systems
"From idea to production API in 6 weeks. WOYOU handled everything — data prep, training, quantization, and deployment. Remarkable speed without cutting corners."
James P.
Founder, FinSight AI

Common questions

We support all major open-weight models — Llama 3 (8B through 405B), Mistral / Mixtral, Gemma 2, Qwen 2.5, DeepSeek V3, Phi-4, Command R+, and Falcon. For closed models, we fine-tune via the official OpenAI and Anthropic APIs. We can also build entirely custom architectures from scratch.
You retain full ownership of your training data and resulting model weights. We sign an IP assignment agreement before any project begins. Your data is never used to train other clients' models and is deleted from our systems upon completion — or retained under NDA for scheduled re-training if you prefer.
For instruction fine-tuning and style adaptation, 1,000–10,000 high-quality examples can produce strong results. Domain knowledge injection typically requires 50K–1M tokens. If your dataset is small, we offer synthetic data augmentation to expand it meaningfully before training.
Starter (LoRA fine-tune + evaluation): 1–2 weeks. Professional (data curation, training iterations, deployment): 4–8 weeks. Enterprise pre-training: scoped individually. We provide a detailed project timeline during the discovery phase, and fixed-scope agreements mean no timeline surprises.
Yes. We are SOC 2 Type II compliant and operate in HIPAA-aligned environments. For maximally sensitive data, we offer on-premise or air-gapped training where all compute and data stays within your infrastructure. VPC deployments on AWS, GCP, and Azure are also fully supported.
