Models

Foundation model providers, open-source models, inference servers, and embedding models.

📄️Closed-source model providers

Anthropic, OpenAI, Google, xAI — the API-only foundation model providers and how they differ in 2026.

Llama, Mistral, Qwen, DeepSeek, Gemma — when self-hosting open weights makes sense, and when it doesn't.

vLLM, TGI, SGLang, Ollama, llama.cpp — the runtimes that serve open-weight models.

OpenAI, Cohere, Voyage, BGE, E5 — the models that turn text into vectors for retrieval.
