What is ChatGPT Agent Mode?

Agent Mode in ChatGPT gives the model autonomy to use tools (web search, code interpreter, file access, custom APIs) on its own without asking for permission at each step. It runs in the ChatGPT web UI and via API.

How much does ChatGPT cost in 2026?

ChatGPT has 6 tiers: Free ($0, limited to GPT-4o mini), Go ($8/mo), Plus ($20/mo, GPT-5.4 full access), Pro ($200/mo, advanced features and higher limits), Business ($25/user/mo, teams), Enterprise (custom). Plus per-token and per-tool-call API billing.

Can I migrate from ChatGPT to OpenClaw?

Yes. System prompts and tool definitions are portable. Export your Custom GPT's instructions and recreate them in OpenClaw's SOUL.md. Conversation history does not migrate. See the vs-openclaw guide for step-by-step instructions.

ChatGPT

OpenAI's hosted agent platform — no self-hosting, per-tool-call billing, Custom GPTs for non-technical teams, and GPT-5.4 advanced reasoning.

6 pricing tiers: Free → Go → Plus → Pro → Business → Enterprise GPT-5.4 with advanced reasoning and Agent Mode Per-tool-call API billing (separate from token cost) 100M+ users

ChatGPT is OpenAI's fully hosted custom agent platform — no servers to run, no infrastructure to manage, and a polished web UI that non-technical users can operate on day one. You set a system prompt, attach tools (web search, code interpreter, file analysis, custom API calls), and share via a link. The tradeoff: you're locked to OpenAI's models, infrastructure, and privacy practices. For users who prioritize ease-of-use and don't need model flexibility, it's unmatched. For privacy-conscious teams or high-volume use cases where cost control matters, OpenClaw may be better long-term.

Critical: Sora video generation has shut down

As of April 2026, Sora video generation capability has been discontinued across all ChatGPT tiers and is no longer available via API. Any workflows relying on Sora must be migrated to external video generation services or archived.

Is ChatGPT right for your use case?

ChatGPT is ideal for teams that need to get started with zero setup and want non-technical members to author custom agents. It's less ideal if you need: model flexibility (swapping Claude, Gemini, or local Ollama), offline capability, tight cost control at high volumes (>10k daily interactions), or full team privacy with your own infrastructure. For those use cases, see OpenClaw, Hermes, or Claude Cowork. Many teams run ChatGPT Plus for team documents AND OpenClaw for personal automation in parallel — they don't conflict.
