Overview

About Fallom

Fallom is the cutting-edge observability platform designed specifically for teams working with production-level large language models (LLMs) and AI agent applications. With its lightning-fast performance and AI-native architecture, Fallom simplifies the complexities of modern AI stacks, offering unparalleled visibility into every single LLM call. In less than five minutes, users can integrate the OpenTelemetry-native SDK into their applications to gain real-time insights into prompts, outputs, tool calls, tokens, latency, and per-call costs. This powerful tool is tailored for engineering and product teams, enabling them to monitor live usage, debug intricate multi-step workflows, and accurately allocate AI expenditures across different models, users, and teams. Fallom serves as an enterprise-ready command center for AI operations, providing essential session-level context, timing waterfalls, and comprehensive audit trails, all of which are necessary for compliance and effective scaling.

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.
