SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Cross-model benchmarking across AI providers to objectively compare performance on the same prompt, helping you choose the best model for your gstack workflows without manual reruns.

Core Features & Use Cases

  • Cross-model benchmarking: run the same prompt across Claude, GPT, and Gemini to compare latency, token usage, and cost.
  • Quality judging: optionally include an external quality judge to assess output quality.
  • Guided workflow: step-by-step prompts to pick a prompt, verify authentication, and run the benchmark; saves results for future comparisons.
  • Use cases: quickly evaluate which model best suits your needs for a given task, or compare model updates over time.

Quick Start

Run the benchmark by selecting a prompt source, choosing authed providers, and reviewing the results.

FAQPage Schema
How do I benchmark cross-model AI performance to compare latency and cost?

Cross-model AI benchmarking solves the problem of objectively comparing performance on the same prompt across Claude, GPT, and Gemini. It helps you choose the best model for your workflows by measuring latency, token usage, and cost without manual reruns.

How do I compare AI model output quality across different providers?

You compare AI model output quality by optionally enabling an external quality judge during the benchmark workflow. This assesses the output quality alongside the latency and cost metrics for each selected provider.

What's the best way to evaluate which AI model best suits a specific task?

The best way to evaluate which AI model suits a specific task is to run a cross-model benchmark. By selecting a prompt source and choosing authed providers, you can compare performance metrics and optionally save the results for future comparisons.

Do I need to authenticate with all providers to run a cross-model benchmark?

You need to authenticate with your chosen providers to run a cross-model benchmark. The guided workflow includes interactive prompts to verify authentication and select the specific authed providers you want to compare before running the benchmark.

Can I save my AI model comparison results for later analysis?

You can save your AI model comparison results for later analysis. The benchmark workflow optionally saves the per-provider results, including latency, tokens, and cost, to a JSON file for future reference or model update comparisons over time.
