Proprietary model

Cursor trains its own proprietary models like Composer, Fast Apply, and the Tab model. They also utilize third-party models such as GPT-4, Claude, Google Gemini 3 Pro, xAI Grok Code, and OpenAI's embedding models. They use various providers for training and fine-tuning their models, including Voltage Park, Databricks MosaicML, and Foundry. Inference is primarily done on Azure and AWS, with tens of thousands of NVIDIA H100 GPUs.

Moat and openness

6/ 10
Moat 6 out of 10

Moat

  • Proprietary Model
  • Proprietary Data
  • Network Effects
  • Switching Costmoderate
  • Unique UX
  • Distributionmoderate

Cursor exhibits some defensibility through its proprietary models (Composer, Fast Apply, Tab model) and a unique, agent-driven UX that integrates multiple frontier models. While it has a significant user base and notable enterprise customers, its reliance on third-party models for complex reasoning and the competitive landscape with GitHub Copilot and Claude Code suggest a moderate switching cost and distribution, preventing a stronger moat.

5/ 10
Openness 5 out of 10

Openness

  • Open model weights
  • Published research
  • Open source contributions
  • Transparency reports
  • Public safety evals

Anysphere, the company behind Cursor, demonstrates moderate openness. They have a significant presence on GitHub with numerous public repositories, including some related to prompt design and GPT-4 for code, indicating contributions to open-source. They also have a whitepaper describing their threat model and security measures. However, the product itself (Cursor) is closed-source, and there are concerns regarding the transparency of their data handling practices, particularly concerning the scope of code context transmission and the lack of a published formal threat model for their agent mode. While they offer SOC 2 Type II certification and DPAs, they do not publicly disclose a full list of sub-processors for GDPR compliance, and their training data composition for proprietary models is not public.

Notable customers

NVIDIACoinbaseUpworkAdobeUberSalesforcePwC

Cursor leads in enterprise revenue among pure-play AI coding vendors, but trails GitHub Copilot in user base and Claude Code in developer satisfaction.

Value and ROI

What it should move: It shortens the path from an issue to a reviewable change.

Best fit

It fits teams with tests, disciplined reviews, and written repository instructions.

The catch

Cursor sends code context to model services and can change many files. Teams must control data settings, diffs, and commands.

  • Box: Uses Cursor for code guardrails, tests and large codebase migrations.[1]
  • Vercel: Uses Cursor to build and test event-streaming infrastructure against cloud environments.[2]
