Test AI models

// Features

Everything to test up to 20 models on your real prompts

Playground, workflows, vision, and benchmarks - compare cost, latency, and output quality side by side before you commit to a model in production.

Strengths • Intelligent routing across Inter, Zendesk, Freshdesk, Help Scout, and Gorgias • Clear cost-per-ticket math if GPT-4o stays on the hard cases only Weaknesses • Over-indexes on flagship models for triage that a cheap classifier can do • Longer latency than needed for first-response drafts

Pro tip Run the cheap models on the same production prompt first. Kimi is thorough but slow — use it for research dumps, not the live ticket path. Cheapest complete answer in this set after DeepSeek, with more detail than Mistral.

// Platform capabilities

Test like you ship with real API data

Single-step tests, workflows, vision, and benchmarks - each built for production prompts, not lab benchmarks.

Playground

Single-step tests - cost & latency

Paste a production prompt, pick models, and run them in parallel. Every response includes token counts, latency, and estimated cost so you can compare side-by-side in seconds.

Playground comparing LLM outputs and costs side by side
WorkflowsNew in v1.7

Multi-step workflow testing

Chain LLM steps like your agent does - pass output from one model as input to the next. Find which hop can move to a cheaper model without breaking quality on your real workload.

Multi-step workflow with per-step costs
Vision

Image analysis comparison

Upload an image with your prompt and compare vision models on the same task. See quality, detail, and per-call cost across providers - not generic vision leaderboards.

BenchmarksPopulating

Security

Your prompts stay yours

We never train on or share your prompts. We use anonymised task type and results to improve community rankings - toggle off anytime.

  • Prompts are used only to run your requested model tests
  • No selling or training on your test inputs or outputs
  • Anonymised task type and results may improve community rankings - toggle off anytime
  • Encrypted in transit; access limited to operational needs
  • Delete test history from your account at any time

// Vs alternatives

What you can't get anywhere else

Tracking tells you you're overpaying. We tell you exactly what to switch to - tested on your real prompt, quality verified, so the switch won't break anything.
