TaglineOpen weights + strong photorealism. The open-source answer.Wire Cursor's full coding-agent runtime into your own apps, scripts, and CI/CD pipelines with a few lines of TypeScript.Google Docs with an AI collaborator baked in.Run LLMs locally. One-line install, GUI optional.
CategoryImageDev PlatformWritingDev Platform
PricingAPI + open weights (Schnell is Apache 2.0)Token-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 + $12/moFree + open source
Best forDevelopers + power users who want control and privacy.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.Essays, long-form drafts, thinking on the page.Devs wanting offline/local LLMs for privacy or experimentation.
Strengths
  • Runs locally on a beefy GPU
  • Very photoreal
  • Best open-weight model
  • 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
  • Clean writing UX — distraction-free
  • +++ prompt triggers AI help
  • Collaboration + AI feedback together
  • Run Llama, Mistral, Qwen, etc. on your laptop
  • Simple CLI + API
  • Hardware-aware (picks the right quant)
Weaknesses
  • Harder to use than hosted tools
  • Needs infra
  • 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
  • Less feature-rich than Google Docs
  • AI ceiling below dedicated tools
  • Needs beefy laptop for larger models
  • Speed way behind cloud APIs
Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.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.)A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier for local inference. If you care about privacy or want to tinker, install this today.
