Overview

About Fallom

Fallom represents the next evolutionary stage in AI operations, an observability platform built from the ground up for the age of intelligent agents. It is designed for AI developers and enterprise teams who have moved beyond initial experimentation and are now scaling complex LLM and agent workloads in production. As these systems grow from simple prompts to intricate, multi-step workflows involving tools, databases, and conditional logic, traditional monitoring tools fall short. Fallom fills this critical gap by providing a comprehensive, real-time window into every LLM interaction. It captures the full spectrum of data—prompts, outputs, tool calls, token usage, latency, and costs—transforming opaque AI operations into a transparent, manageable, and optimizable system. Its core value proposition is enabling businesses to progress from merely deploying AI to mastering it, ensuring reliability, controlling spend, and maintaining compliance as their AI initiatives mature and evolve.

About OpenMark AI

OpenMark AI is a web application for task-level LLM benchmarking. You describe what you want to test in plain language, run the same prompts against many models in one session, and compare cost per request, latency, scored quality, and stability across repeat runs, so you see variance, not a single lucky output.

The product is built for developers and product teams who need to choose or validate a model before shipping an AI feature. Hosted benchmarking uses credits, so you do not need to configure separate OpenAI, Anthropic, or Google API keys for every comparison.

You get side-by-side results with real API calls to models, not cached marketing numbers. Use it when you care about cost efficiency (quality relative to what you pay), not just the cheapest token price on a datasheet.

OpenMark AI supports a large catalog of models and focuses on pre-deployment decisions: which model fits this workflow, at what cost, and whether outputs are consistent when you run the same task again. Free and paid plans are available; details are shown in the in-app billing section.
