RLHF and expert feedback providers compared · Updated · Reviewed by the Opus Research editorial desk

What does this hub cover for nearshore and Latin American hiring?

Use this hub to choose how you will buy RLHF services and assess the people doing the work. Start with a task your team needs completed: ranking model responses, checking code, or reviewing evaluation results.

Write down who will teach the scoring rules and resolve disagreements. Before requesting proposals, name the manager who can review the hire's work. If you need the provider to manage delivery, ask it to define that responsibility in writing.

For Opus, the client chooses the finalist and manages day-to-day work. This site is an Opus-owned reference; recommendations are editorial. The hiring process describes that arrangement.

Which entries should you read first?

Choose the entry that addresses your next decision. Bring the resulting questions to each provider so you can compare answers against the same requirements.

  • Hiring models: decide who should find the person, handle employment, and manage daily work. Read this before comparing staff augmentation with a managed service.
  • How to choose: prepare a shortlist and request evidence for the work you need done. Ask for a sample that resembles your tasks.
  • RLHF annotator and AI trainer: define a role focused on response ranking and feedback. For code-focused tasks, use the coding agent trainer guide.
  • Role scorecard and interview loop: turn your requirements into a work sample. Include an ambiguous case and ask the candidate to explain the rating.
  • Cost: compare the full quote. Ask who pays for reviewer training, tooling, and rejected work.
  • IP, security and devices: check access and ownership before sharing task data. Ask how access ends when a reviewer leaves.
  • Contract checklist: record the agreed scope, acceptance rules, and exit terms before signing.

When comparing costs, keep the quoted scope beside the price. Opus charges one flat monthly rate per hire. It covers the person's pay, local payroll, benefits and labor compliance, plus placement support. There is no separate recruiting fee. The rate depends on role, seniority and location. See pricing.

Dollar rates: Not published. Ask for a written quote for your role.

Before a provider call, prepare a short role description and a safe sample task. Include the hours you need, who will approve ratings, and what a successful first assignment looks like. Ask the provider to respond to those requirements in its proposal.
