	Suno S	Sora A	Claude Agent SDK S	Cursor S
Tagline	Prompt to full song with vocals, instruments, the works.	OpenAI's video model. Long clips, cinematic quality.	Anthropic's SDK for building your own agents on Claude.	VS Code fork that made AI coding actually work.
Category	Audio	Video	Agents	Coding
Pricing	Free + $10/mo + $30/mo	Included with ChatGPT Plus/Pro	API usage + SDK is free	Free + $20/mo Pro + $40/mo Business
Best for	Jingles, intros, demos, sketches, personal use.	ChatGPT subscribers experimenting with cinematic shots.	Developers building custom agents for their own company/product.	Developers. Non-developers who want to ship working code.
Strengths	Real songs with real lyrics v4 is very good Quick turnaround	Up to 20-sec clips at 1080p Strong physics + scene composition Storyboard feature for longer narratives Remix existing videos	Production-grade agent primitives Built on Claude (best reasoning) Full control — build exactly what you need	Tab completion feels like mind-reading Composer for multi-file edits Runs Claude, GPT, Gemini — you pick
Weaknesses	Copyright gray zone Audio quality behind studio	Stricter content policy than competitors Hit-or-miss on complex motion Text-in-video still struggles	Developer-only You build the UI	Can feel overwhelming for non-coders Expensive at scale
Kai's verdict	S-tier in its category. The first AI music tool I'd actually listen to.	A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.	S-tier for builders. The right primitives. What Kai is built on under the hood.	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
