What it is
Labelbox is software for AI training data, reinforcement learning environments, evaluations, and enterprise agent workflows. Its Recursion platform lets enterprises run fleets of agents that can begin from schedules, alerts, events, or API calls. Agents can plan jobs, run specialist agents in parallel, use sandboxes, and return graded results with evidence to connected applications such as Slack, GitHub, Linear, Salesforce, Databricks, Google Drive, Box, and Jira. Horizon supplies reinforcement learning environments and evaluations for model post-training in reasoning, tool use, and computer use. Labelbox Annotate includes more than 10 editors for multimodal chat, LLM evaluation, prompt and response generation, computer vision, and natural language processing. Expert services cover reinforcement learning from human feedback, supervised fine-tuning, preference ranking, red teaming, and coding or AI-agent tasks. The company says its expert network covers more than 200 domains and 30 languages. Catalog connects data from more than 25 cloud sources. Labelbox offers web and API access, model-assisted labeling, team collaboration, and a free plan with 10,000 free Labelbox units before card charges.
