FAQs
Omni Evals is Hugo’s unified, six-layer evaluation architecture for frontier AI. Managed teams of university-educated specialists audit the full reasoning trace of your models, from static perception to agentic tool-use and embodied action, and stream clean, human-verified data back into your training loop.
It is the practice of grading how a model reached an answer, not just the final output. Hugo’s engineers evaluate each step of the function-calling loop, Intent, Reasoning, Action, and Observation, and run code inside isolated sandboxes to catch reward hacking, hallucinated logic, and unsafe tool calls that automated test suites miss.
Through a secure, programmatic API and telemetry handshake, not CSV or Excel handoffs. We work inside your own Braintrust or LangSmith tenant, or stream through a Hugo-hosted Langfuse pipeline, so audited golden datasets flow directly into your fine-tuning loop.
Hugo delivers high-volume, enterprise-grade data labeling and human-in-the-loop validation across three core pillars:
- Image, Video & Sensor Fusion: Bounding boxes, polygons, semantic segmentation, and 3D point cloud/LiDAR annotation for computer vision and autonomous systems.
- Text & NLP: Named Entity Recognition (NER), text classification, intent mapping, and sentiment analysis.
- GenAI & LLM Alignment: Expert RLHF (Reinforcement Learning from Human Feedback), prompt evaluation, adversarial red teaming, and toxicity filtering.
We scale training data pipelines across nearly every major vertical. Rather than offering surface-level analytics, we focus on domain-specific edge cases within:
- Advanced Tech & Core AI: LLM development, EdTech, gaming, art and design, and conversational dialogue systems.
- Autonomous Mobility & Spatial AI: Aerospace, automotive (AV perception), maritime, and space exploration.
- Highly Regulated Enterprise: Legal and compliance document review, insurance risk modeling, and secure cybersecurity threat detection.
- Precision Industries: Medical imaging segmentation, agricultural drone analytics, and nanotechnology modeling.
We are built for flexibility. While we routinely manage high-volume enterprise pipelines, we also partner with specialized startups and regional sovereign initiatives. Our 2-week sandbox-to-pilot framework allows teams to start with hyper-targeted, high-complexity datasets, calibrate the guidelines, and scale the workforce up or down dynamically as their model matures.
We are built to ingest virtually any unstructured data type. Our teams routinely handle high-resolution images, multi-frame video, raw text corpora, multi-speaker audio files, and complex spatial datasets like LiDAR and sensor-fusion outputs.
We consistently hit an industry-leading 98.90% precision benchmark. We achieve this through a rigorous multi-stage consensus validation loop and internal QA layers. Before touching live client data, our annotators undergo two weeks of strict training and workflow calibration to align perfectly with your project guidelines.
We don’t use anonymous, crowdsourced click-workers. Hugo’s differentiator is our dedicated, fully managed workforce composed of university-educated talent. This global, academically diverse talent pool provides the critical reasoning, logical deduction, and objective analysis required to handle complex, nuance-heavy tasks like LLM alignment, RLHF, and strict legal or medical labeling.
We are a dedicated human-in-the-loop workforce engine. While we seamlessly adapt to our clients’ automated pre-labeling workflows to speed up throughput, our core value is delivering human intelligence, validation, and manual precision where automated models fall short.
We keep your engineering overhead low. Your internal data science or product team trains a dedicated Hugo Project Manager and QA Lead on your proprietary guidelines. Our leadership team then handles the mass training, onboarding, and daily management of the annotation agents, functioning as a seamless extension of your organization.
We can take your project from sandbox to full production scale in as little as two weeks. Once we review your guidelines, we build a customized pilot plan and begin annotating your sample data within 48 hours to lock in quality standards before scaling up the team.
We are entirely tool-agnostic. Our teams are highly flexible and well-versed in industry-standard commercial software like Labelbox, CVAT, Dataloop, and Kili, open-source tools like LabelMe, or your own custom, proprietary labeling interfaces and APIs.
Every Hugo squad includes a dedicated, non-billing Project Manager who oversees daily operations, tracks throughput SLAs, and enforces quality control. This PM acts as your single point of contact, ensuring flawless communication with your in-house machine learning engineering team.
Security is embedded in our infrastructure. We are ISO 27001 certified, SOC 2 certified, and fully GDPR compliant. We safeguard your proprietary datasets and LLM prompts using industry-best practices, including:
- Encryption: Full data encryption both at rest and in transit.
- Access Control: Strict, role-based access management ensuring only vetted, authorized personnel see your data.
- Auditing: Continuous security auditing and compliance monitoring to mitigate any risk of data leaks.
Our standard model is built on transparent, industry-leading hourly labor rates, giving you a dedicated team mapped directly to your sprint cycles. For specific, highly standardized workflows, we are happy to structure pricing based on data volume. We also offer volume discounts for bulk data pipelines and long-term enterprise contracts.
