Conversational AI & LLMs
The Data Behind Models That Think, Reason, and Stay Safe
The next frontier of AI capability is determined at the data layer. Nextura is the annotation partner for frontier AI labs building the next generation of large language models — from pre-training corpora to RLHF to red-team safety.
What we deliver here.
RLHF & Preference Data
Human preference ranking, comparison pairs, and reward signal datasets annotated by domain experts — coders, lawyers, doctors and scientists.
Instruction Tuning
Instruction-response pair creation, chain-of-thought annotation, and reasoning trace labeling across math, code, science, and general domains in 30+ languages.
Red-Teaming & Safety
Adversarial prompt engineering, jailbreak taxonomy coverage, harm classification, and safety classifier training data — pre-deployment, not post-incident.
Agentic AI Annotation
Trajectory-level preference annotation, tool-use labeling, and multi-turn reasoning trace evaluation for AI agent and orchestration model training.
Multilingual LLM Data
Native-speaker instruction tuning data across 30+ languages — culturally authentic, register-aware, and validated by dialect specialists, not translation layers.
Synthetic Data
Human-in-the-loop synthetic data generation, statistically faithful to real-world distributions while remaining privacy-safe and regulator-cleared.
Results that survive production.
