Compare AI tools

	GitHub Copilot B	Cursor S	Claude Agent SDK S	Groq S
Tagline	Microsoft/GitHub's autocomplete. Deep VS Code + JetBrains integration.	VS Code fork that made AI coding actually work.	Anthropic's SDK for building your own agents on Claude.	The fastest AI inference in the world. Crazy low latency.
Category	coding	coding	agents	dev platform
Pricing	Free (limited) + $10/mo Pro + $19/mo Business	Free + $20/mo Pro + $40/mo Business	API usage + SDK is free	Free tier + pay-as-you-go API
Best for	Teams with GitHub already. Devs who don't want to change IDEs.	Developers. Non-developers who want to ship working code.	Developers building custom agents for their own company/product.	Developers who need sub-100ms LLM responses.
Strengths	Great enterprise story Works in your existing IDE Chat + autocomplete	Tab completion feels like mind-reading Composer for multi-file edits Runs Claude, GPT, Gemini — you pick	Production-grade agent primitives Built on Claude (best reasoning) Full control — build exactly what you need	500+ tokens/sec on Llama/Mixtral — feels instant Custom LPU hardware Great free tier
Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Can feel overwhelming for non-coders Expensive at scale	Developer-only You build the UI	Open-weight models only (no Claude/GPT) Less flexibility on custom configs
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.	S-tier for builders. The right primitives. What Kai is built on under the hood.	S-tier for speed. When latency is the product, start here.
