AI/LLM · Multi-Cloud · Native (own / self-hosted weights)
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]
DevTools · Multi-Cloud · Native (own / self-hosted weights)
Cursor runs a multi-cloud, event-driven architecture with most CPU/backend services on AWS, major GPU inference clusters on Azure plus newer GPU clouds, and specialized AI workloads on GCP, fronted by stateless gateways, queues, and GPU worker fleets for LLM inference and agents.[6][10] Workspace data and embeddings flow through turbopuffer, Pinecone, and Kafka-compatible streams, with Temporal-based orchestration for agent workflows and large multi-GPU clusters (including Fireworks AI-hosted proprietary fine-tuned models) serving code-focused LLMs.[4][6][7][8][10]

Perplexity operates a multi-cloud architecture: it historically built and hosted its Sonar models on AWS (including Bedrock for Anthropic/Claude) while later signing a large Azure agreement to deploy models via Microsoft Foundry, indicating active use of both providers.[1][3][8][9][15] Its core production stack centers on proprietary Sonar LLMs (built on and fine‑tuned from open-source bases like Mistral and later Llama 3.x) combined with partner frontier models (GPT‑5/4-class, Claude, Gemini, Grok) selected per query.[1][2][5][6][10][11][13][14]
