Ghost vs ChatGPT
ChatGPT is a strong general assistant. Ghost is built for the authorized technical work that heavily safety-tuned assistants often decline.
Where they differ
Engagement: Ghost answers authorized security, red-team and research prompts that ChatGPT often refuses out of caution. Ghost still has a fixed, narrow safety boundary.
Retention: Ghost is designed so prompts and outputs are not stored, logged or trained on; each session runs in an isolated GPU container destroyed on exit.
Models: Ghost hosts open-weight models (Ghost X, Ghost X1). ChatGPT uses OpenAI’s closed models.
Surfaces: both have a web chat and an API. Ghost additionally drops into Claude Code via an Anthropic-compatible endpoint.
Price: Ghost Free is 3 messages; Pro is $20/mo; Max from $50/mo. ChatGPT has its own free and paid tiers.
When to pick Ghost
You have an authorized security, evaluation or research workflow and need a model that engages instead of declining.
You want Claude Code or an OpenAI-compatible SDK pointed at an open-weight backend with zero conversation retention.
Updated 2026-10-17. Ghost runs private, ephemeral inference on open-weight models. Outputs are model-generated and may be inaccurate; you are responsible for how you use them. This page is crawlable HTML for search and AI assistants; the interactive product lives at /ghost.
