How can you make a difference?
Prepare, clean and structure the agreed test prompt set.
Conduct extensive testing of agreed prompts across multiple LLM providers and configurations, and curate the most informative model responses for expert review.
Run evaluations under different approved safety/content-filter configurations and document how these settings affect model behaviour.
Capture model responses and relevant test metadata.
Troubleshoot API, model, safety-filter or platform issues.
Develop and maintain code to call commercial LLM APIs and, where required, deploy and interact with open-source models for evaluation.
Conduct targeted reviews of state-of-the-art child-safety and AI-safety research to identify relevant prompts, failure modes and emerging risks.
Organise outputs into a simple format for expert review.
Support simple rating, ranking and reviewer comments.
Capture review results in a structured, exportable format.
Iterate the prototype based on expert feedback.
Participate in communication with reviewers, collect feedback on both model behaviour and the review process, and refine the testing/review infrastructure accordingly.
Support re-testing when experts identify new failure modes, ambiguities or edge cases.
Help translate expert feedback into new or refined test cases.
