Overview
About Fallom
Alright, let's break it down. Fallom is like the ultimate control room for your AI chaos. If you're building with LLMs or AI agents, you know the vibe: stuff works in dev, then you ship to production and suddenly it's a black box of mystery calls, weird latencies, and surprise bills from OpenAI. Fallom fixes that. It's an AI-native observability platform built from the ground up to give you X-ray vision into every single LLM call happening in your apps. We're talking full end-to-end tracing that shows you the prompts, the outputs, the tool calls, the tokens, the latency, and even the exact per-call cost. It's designed for devs, product managers, and data science teams who are tired of flying blind and need a single source of truth for their AI ops. With a slick dashboard that serves up context by session, user, or customer, you can debug weird agent behavior in seconds, monitor live usage, and see exactly who or what is burning through your API budget. Plus, it's built on OpenTelemetry, so you can instrument your stack in, like, five minutes flat. And for the enterprise crowd sweating compliance? Fallom's got your back with audit trails, logging, model versioning, and consent tracking to keep you chill with regulations like GDPR and the EU AI Act. In short, it's your wingman for building reliable, cost-controlled, and high-performance AI applications.
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.
