TaglineRun any open-source AI model with an API call.Wire Cursor's full coding-agent runtime into your own apps, scripts, and CI/CD pipelines with a few lines of TypeScript.Chinese open-weight powerhouse. Crazy cheap, genuinely smart.Open weights + strong photorealism. The open-source answer.

PricingPay per second of computeToken-based; requires Cursor plan (Pro from $20/mo). Composer 2 at $0.50/$2.50 per M tokens (in/out); fast variant $1.50/$7.50 per M tokens.Free web + ultra-cheap API (~$0.14/M input tokens)API + open weights (Schnell is Apache 2.0)
Best forDevelopers using open-source models (Flux, SDXL, Whisper, etc).Engineering teams who already use Cursor and want to embed its coding-agent runtime into CI/CD pipelines, backend services, or internal developer tools without building agent infrastructure from scratch.Developers + cost-conscious builders. Anyone fine with self-hosting.Developers + power users who want control and privacy.
Strengths
  • Tens of thousands of models (image, video, audio, LLMs)
  • One-line API for any model
  • Cog framework for custom model deploy
  • Same runtime as the Cursor IDE — no reinventing sandboxing, context management, or model routing
  • Three execution modes: local machine, Cursor cloud VMs (isolated per-agent), or self-hosted workers for air-gapped teams
  • Cloud agents are durable — keep running even if your laptop sleeps or connection drops, and can open PRs automatically on finish
  • Full harness included: codebase indexing, MCP servers, skills, hooks, and multi-agent delegation via subagents
  • Visible in Cursor's Agents Window — programmatic runs can be inspected or taken over manually in the IDE
  • Open weights you can self-host
  • Strong reasoning + math
  • Near-free API pricing
  • DeepSeek-V3 / R1 are serious models
  • Runs locally on a beefy GPU
  • Very photoreal
  • Best open-weight model
Weaknesses
  • Cold starts on less-popular models
  • Pricing gets real at scale
  • TypeScript-only SDK — no official Python or other language bindings at launch
  • Public beta status means API surface and pricing can shift without much notice (Cursor has a track record of surprise pricing changes)
  • Cloud VM costs layer on top of subscription credits, making cost estimation non-trivial at scale
  • Data goes to servers in China — privacy concerns for business use
  • Chinese policy filters
  • English polish trails Western models
  • Harder to use than hosted tools
  • Needs infra
Kai's verdictS-tier for open-source model APIs. The default in this space.If your team is already in the Cursor ecosystem, this is a genuinely compelling way to turn ad-hoc AI coding sessions into durable, automated workflows — but the beta label and Cursor's history with opaque pricing mean you'll want to set hard budget guardrails before going to production. (Verdict pending Phi's full review.)S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.A-tier. S-tier if you self-host. The reason open-source image gen matters.
