TaglineThe fastest AI inference in the world. Crazy low latency.Google's video model. Baked into Gemini + YouTube Shorts.Wire Cursor's full coding-agent runtime into your own apps, scripts, and CI/CD pipelines with a few lines of TypeScript.Run any open-source AI model with an API call.

PricingFree tier + pay-as-you-go APIIncluded with Gemini Advanced $20/mo + YouTube creator toolsToken-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.Pay per second of compute
Best forDevelopers who need sub-100ms LLM responses.Gemini Advanced users, YouTube Shorts creators.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 using open-source models (Flux, SDXL, Whisper, etc).
Strengths
  • 500+ tokens/sec on Llama/Mixtral — feels instant
  • Custom LPU hardware
  • Great free tier
  • Included with Gemini Advanced
  • YouTube Shorts native integration
  • Strong prompt understanding
  • 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
  • Tens of thousands of models (image, video, audio, LLMs)
  • One-line API for any model
  • Cog framework for custom model deploy
Weaknesses
  • Open-weight models only (no Claude/GPT)
  • Less flexibility on custom configs
  • Still catching up on quality vs Kling/Runway
  • Less control than pros need
  • 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
  • Cold starts on less-popular models
  • Pricing gets real at scale
Kai's verdictS-tier for speed. When latency is the product, start here.A-tier if you already pay Gemini. B-tier standalone.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 open-source model APIs. The default in this space.
