LLM Comparator: A Way to Evaluate Language Models

If you’ve ever wondered how to compare two LLMs side-by-side—without sifting through endless text—LLM Comparator has your back. Built on top of Google’s PAIR research, this tool lets you visually analyze model performance with an interactive interface highlighting when, why, and how one model outshines another.

Here’s how it elevates model evaluation:

• At-a-glance clarity: Compare win rates across prompt categories. Visual panels show whether Model A or Model B performs better overall and in specific cases.
• Deeper insight: Dive into the “Rationale Summary” to see exactly what factors—conciseness, detail, tone—made one response more effective.
• Custom and scalable: Add your own evaluation metrics with custom functions or rely on the Python library to generate the JSON      needed for the visual dashboard.

Whether you're tuning your latest model or making improvement decisions with data, LLM Comparator brings transparency, efficiency, and context to your evaluation workflow.

As teams across industries embrace AI, prompt engineering has become a critical skill—but one that’s often messy, unstructured, and hard to manage at scale. That’s where PromptVCS comes in: a lightweight, intuitive version control system built specifically for prompt development and collaboration.

With PromptVCS, you can create repositories for your prompt workflows, branch new ideas, track edits over time, and roll back changes just like you would with Git. But it’s more than just version history. You can tag releases, compare performance across prompt iterations, and even collaborate across teams with built-in role management. Whether you're iterating on a chatbot prompt, refining research instructions, or managing a multi-agent pipeline, PromptVCS gives you structure and transparency.

It’s a tool designed for how modern AI teams work—fast, iterative, and collaborative.

If you’ve ever found yourself guessing how much your AI workflows might cost, the AI Cost Calculator is the clarity tool you’ve been missing. Designed with both developers and project managers in mind, this simple web app makes it easy to estimate expenses across a wide range of language models from OpenAI and Anthropic to Google, Mistral, and beyond. 

You will start by selecting a model, plug in your prompt and completion token counts, and instantly see the estimated cost per request. It even supports multiple currencies and provides daily/weekly usage breakdowns. Whether budgeting for an enterprise-scale deployment or tracking expenses on a side project, this calculator helps you stay proactive, not reactive. It removes the guesswork, builds pricing awareness, and lets you compare providers head-to-head, all in a clean, no-fuss interface. It’s necessary if you work with LLMs regularly and want to keep your AI usage sustainable.
