Panel A Anthropic / Claude
Compare the launch risk of two LLM deployment plans.
Plan A reduces infrastructure complexity but increases vendor dependence. Plan B adds orchestration overhead while improving routing resilience and fallback coverage.

Panel B OpenAI / GPT
Compare the launch risk of two LLM deployment plans.
Plan A optimizes time-to-market. Plan B is stronger for long-term procurement leverage, model diversity, and observability if your team can support the added operational surface area.

Research without a paywall

Create a free account to access AI Labs, connect OpenRouter, and start controlled prompt testing in a dedicated research workspace.

Basic

Faster iteration

Basic members get the same research console with the wider Prompt Index toolkit for teams that need more daily usage and workflow depth.

Pro

Full-stack experimentation

Pro members can use AI Labs alongside the full premium stack for more advanced prompt engineering, content workflows and evaluation loops.

Why Teams Use AI Labs for Prompt Research

Side-by-Side Model Comparison

Run the same prompt through different models and compare reasoning style, quality, output shape and consistency in one controlled interface.

Parameter Testing

Adjust temperature, top-p and token limits to test how changes affect creativity, determinism, verbosity and cost profile before you ship prompts into production.

System Prompt Evaluation

Compare prompt scaffolds, system instructions and role framing across providers so you can find stronger defaults for support, content, coding and research workflows.

Research Console UX

The interface is designed for active testing, not demo theatrics: fast model switching, visible telemetry, clean transcripts and a focused comparison-first layout.

OpenRouter Integration

Connect once through OpenRouter to access a large provider catalog inside a single evaluation surface, with your session managed through The Prompt Index.

Member Access Only

AI Labs requires account login so connection state, consent tracking and model usage behave predictably. Guests see the product page, members get the live console.

Frequently Asked Questions

Can guests use AI Labs?

No. AI Labs is login-only. Guests can explore the product overview and feature details, but the live research console requires a signed-in free, basic or pro account.

What do I get with a free account?

Free members can access the AI Labs workspace, connect OpenRouter and run prompt tests inside the same interface used by paid members. Paid plans expand access across the wider Prompt Index product set.

How does side-by-side model testing work?

You select a model for each panel, enter the same prompt, and compare responses side by side. This makes it easier to evaluate tone, structure, compliance and reasoning differences across models.

Why require login for OpenRouter connection?

Login keeps connection state, consent capture and backend proxy usage tied to a real account. That avoids the broken guest flow where a connection can start but cannot be stored reliably.
