How Apex helps you train, align and test your LLM
Collect & pre-train
We source and create large, high-quality datasets so your model starts with the right knowledge.
Fine-tune & RLHF
Experts write ideal answers and rank model replies to teach your model how to behave.
Test & red-team
We probe for mistakes, bias and unsafe answers, and feed the fixes back into training.
Launch with confidence
You ship a model that is accurate, safe and aligned with what people expect.
