Overview
About Fallom
Fallom is the essential AI-native observability platform built specifically for the complexities of Large Language Model (LLM) and AI agent workloads. In a landscape where AI operations are critical but opaque, Fallom delivers the non-negotiable visibility that development and enterprise teams require. It provides comprehensive, end-to-end tracing for every LLM call in production, capturing vital data like prompts, outputs, tool calls, token usage, latency, and cost. This platform is a necessity for AI developers, data scientists, and enterprise teams who must monitor usage in real-time, ensure compliance with evolving regulations, and optimize costly AI operations. By offering a single OpenTelemetry-native SDK, Fallom enables instrumentation in minutes, eliminating blind spots. The core value proposition is absolute control: the ability to troubleshoot performance bottlenecks, attribute costs accurately across teams and models, and maintain robust audit trails for governance, all from a unified dashboard. Without Fallom, organizations are flying blind with their most critical and expensive AI initiatives.
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.
