	Stable Audio A	OpenRouter S	Claude Code S	Gemini A
Tagline	Stability AI's open audio model. Loops + SFX + background.	One API, every model. Pay-as-you-go, no subscriptions.	Anthropic's CLI agent. Opus-powered, operates on your repo directly.	Google's answer. Best integrated with Workspace + free for a lot.
Category	Audio	Dev Platform	Coding	Chatbots
Pricing	Free + $12/mo Pro + enterprise	Pay per token — model-dependent	Part of Claude Pro/Max/Team plans	Free + $20/mo Advanced (bundled with 2TB Drive)
Best for	Game developers, podcasters needing SFX, video creators needing background music.	Developers experimenting across models. Apps that want fallback logic.	Developers who want an agent, not autocomplete. Large refactors, tests, docs.	Anyone already on Google, research tasks, summarizing long documents.
Strengths	Open-weight model available Great for loops + game audio + SFX Commercial-use clarity	300+ models from one endpoint Automatic fallbacks between providers No subscription — just pay what you use	Runs locally, edits your actual files Strong on large codebases with 1M context Great at multi-step tasks	Native Google Workspace integration Very long context (1M+) Deep Research feature Free tier is generous
Weaknesses	Not for full songs with vocals Shorter generation limits	Slight markup over direct API Some provider features not exposed	Terminal-based — learning curve Can't be used without Claude subscription	Writing quality trails Claude Over-refusals on edge content UI is cluttered
Kai's verdict	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	S-tier for model-shopping. I use this for every prototype before committing.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
