Anthropic runs **Claude** and related services on a safety-first **multi-cloud** compute fabric spanning AWS Trainium2, Google TPUv7 and NVIDIA GPUs, fronted by Kubernetes‑based microservices (API gateways, orchestration, rate limiting, caching, and safety filters), with state held in PostgreSQL, vector stores, Redis, and cloud object storage.[1][10][13] Production offerings like Claude API and Managed Agents expose a fully managed orchestration and agent runtime, while emerging self‑hosted sandboxes move tool execution into customer infrastructure but keep Claude inference, routing, and session state on Anthropic’s cloud.[2][3][11]

Reka trains and serves its own multimodal encoder–decoder frontier models (Core, Flash, Edge) on custom Kubernetes-based GPU clusters spanning multiple vendors, using PyTorch on large H100/A100 fleets and a separate A10/A100 inference stack.[2][5] Public deployment is via Reka’s own web app and API endpoints (chat.reka.ai, platform.reka.ai, showcase.reka.ai), with an OpenAI-compatible API server for Edge provided through vLLM and Hugging Face artifacts.[2][7][12]
