Covers the distinction between LLMs, models, tokens, context windows, and reasoning modes. Explains the difference between frontier labs (Anthropic, OpenAI, Google DeepMind) and open-weight labs (DeepSeek, Meta, Mistral), and clarifies that 'open weight' is not the same as 'open source'. Defines client types including web UIs, IDE plugins, terminal clients like Claude Code and Codex, and specialized harnesses. Also introduces the concept of 'initiatives' using Anthropic's Glasswing and OpenAI's Daybreak as examples. Includes a reference table mapping labs, models, clients, and initiatives. ## Full article daily.dev links to this article rather than hosting it.
