Figure Eight
Data annotation platform with HITL workflows for training AI models. Offers APIs for scalable human review in agent data pipelines.
Use with care — notable gaps remain
You need scalable human annotation for training data in agent pipelines, but manual labeling is slow, costly, and inconsistent at volume.
Up to 20x faster annotation with 50% cost savings via MLADL; scalable to millions of tasks, but expect contributor quality variability and communication hurdles requiring task redesigns.
Non-technical team members struggle to build complex annotation pipelines without scripting or data science expertise.
Quick setup for production data loops, but initial tuning needed for consistency; strong for images/video/NLP, multilingual support via 1M+ crowd.
No direct contributor communication
Can't interact with annotators to clarify instructions, leading to errors if tasks aren't perfectly specced—requires over-designing jobs for clarity.
Quality variability in crowd
Trained non-expert contributors can misinterpret tasks without feedback loops; mitigate by using ML confidence thresholds, peer review, and granular workflows.
Figure Eight prioritizes workflow automation over per-task precision; now Appen-integrated for massive crowd scale.
Pick for complex, multi-step pipelines and high-volume HITL at lower cost.
Choose Scale for expert-managed teams and superior accuracy on nuanced tasks.
