	Claude Agent SDK S	Stable Audio A	GitHub Copilot B	Recraft S
Tagline	Anthropic's SDK for building your own agents on Claude.	Stability AI's open audio model. Loops + SFX + background.	Microsoft/GitHub's autocomplete. Deep VS Code + JetBrains integration.	Vector + raster AI for designers. Actually controls the output.
Category	Agents	Audio	Coding	Image
Pricing	API usage + SDK is free	Free + $12/mo Pro + enterprise	Free (limited) + $10/mo Pro + $19/mo Business	Free + $12-$48/mo
Best for	Developers building custom agents for their own company/product.	Game developers, podcasters needing SFX, video creators needing background music.	Teams with GitHub already. Devs who don't want to change IDEs.	Designers, brand teams, anyone needing vector output or tight style control.
Strengths	Production-grade agent primitives Built on Claude (best reasoning) Full control — build exactly what you need	Open-weight model available Great for loops + game audio + SFX Commercial-use clarity	Great enterprise story Works in your existing IDE Chat + autocomplete	Exports SVG vectors — rare in AI image gen Strong style control + consistency Brand kit for consistent outputs
Weaknesses	Developer-only You build the UI	Not for full songs with vocals Shorter generation limits	Less agentic than Cursor/Claude Code Model quality varies	Less hyped than Midjourney Learning curve for non-designers
Kai's verdict	S-tier for builders. The right primitives. What Kai is built on under the hood.	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for designers. The only one that takes vectors seriously.
