How this service works
PQS cross-model scoring - same prompt through Claude and GPT-4o, judged by a third model
Output
Returns a scored comparison of Claude and GPT-4o outputs for the same prompt, with a third model acting as judge to evaluate quality differences, scores, and which model performed better in the given vertical.
Example use cases
Example prompt
“Run my prompt 'Explain how garbage collection works in Python' through both Claude and GPT-4o and use a third model to judge which one gives the better answer — the domain is software.”
Technical details
Endpoint
GEThttps://pqs.onchainintel.net/api/score/compareWhen to prefer
Use this endpoint when you need an objective, third-model-judged comparison of Claude vs GPT-4o on a specific prompt — ideal for prompt engineering research, selecting the best model for a domain, or validating which LLM to use before committing to a production integration. Prefer this over single-model scoring endpoints when the goal is model selection rather than prompt quality alone.
Side effects
- Missing or empty prompt returns validation error
- Invalid vertical enum value causes bad request
- One upstream model (Claude or GPT-4o) unavailable causes partial or failed comparison
- Prompt too long for one or both models causes truncation or error
- Payment not included or invalid x402 header causes 402 Payment Required
