Fireworks is an AI platform that provides training and inference tools to transform open models into domain-specific or specialized intelligence. The service offers capabilities for model training, fine-tuning and serving to support customized AI deployments.

Together AI (branded Together) operates an "AI native cloud": a platform for deploying, running, and scaling AI models and applications. The service provides infrastructure and tooling for developing and serving machine learning and large language models.

A managed inference service from Red Hat for running enterprise AI inference workloads without directly selecting or managing GPUs. It provides usage-based scaling while abstracting underlying GPU capacity.

Experiential Labs is an open-source AI gateway that provides an OpenAI-compatible endpoint for hosted model providers, customer-owned provider keys, private GPUs, and self-hosted models. It routes requests through a single API and key while handling provider access, model selection, failover, and streaming responses. Its optional intelligence layer monitors traffic to identify model switches, improve cache hit rates, and route requests to customer-owned fine-tuned models. The service also provides organization-wide usage attribution, request logs, spend reporting, access controls, model allowlists, and per-key spending caps scoped by team, person, agent, or tool. It can be used as a hosted gateway or self-hosted, with hosted inference and Pro offered alongside the open-source gateway.

DeepSeek (深度求索) is an AI research project and model provider that develops and open-sources large foundation models (notably named DeepSeek-V4 and DeepSeek-R1) and provides hosted inference via a chat interface (“DeepSeek AI”) and an API. It publishes open-source model releases and offers a hosted API for text-based prompt inference; video reports state DeepSeek models can be exposed as external backends and routed into the Codex model picker via Codex Router.
