	DALL-E 3 B	Claude Code S	OpenRouter S	Claude Agent SDK S
Tagline	OpenAI's image model. Built into ChatGPT Plus.	Anthropic's CLI agent. Opus-powered, operates on your repo directly.	One API, every model. Pay-as-you-go, no subscriptions.	Anthropic's SDK for building your own agents on Claude.
Category	Image	Coding	Dev Platform	Agents
Pricing	Included with ChatGPT Plus $20/mo	Part of Claude Pro/Max/Team plans	Pay per token — model-dependent	API usage + SDK is free
Best for	ChatGPT Plus users who want images without paying extra.	Developers who want an agent, not autocomplete. Large refactors, tests, docs.	Developers experimenting across models. Apps that want fallback logic.	Developers building custom agents for their own company/product.
Strengths	Excellent prompt understanding Built into ChatGPT — no extra subscription Good at composition + concepts	Runs locally, edits your actual files Strong on large codebases with 1M context Great at multi-step tasks	300+ models from one endpoint Automatic fallbacks between providers No subscription — just pay what you use	Production-grade agent primitives Built on Claude (best reasoning) Full control — build exactly what you need
Weaknesses	Aesthetic ceiling below Midjourney + Ideogram Text rendering worse than Ideogram No fine control	Terminal-based — learning curve Can't be used without Claude subscription	Slight markup over direct API Some provider features not exposed	Developer-only You build the UI
Kai's verdict	B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	S-tier for model-shopping. I use this for every prototype before committing.	S-tier for builders. The right primitives. What Kai is built on under the hood.
