Cursor: What's included in Cursor's free tier and what are its limits?

The free Hobby plan provides 2,000 completions per month and 50 slow premium requests, with access to basic autocomplete features. Codebase-wide indexing and the Composer multi-file editor are not available on the free plan.

Source
Anthropic API: What discounts does the Claude API offer?

Batch processing saves 50% on API costs. Prompt caching reduces token costs by up to 90% for cached reads (charged at 80% discount compared to standard rates). Fast Mode for Opus 5 costs 2x standard pricing for up to 2.5x faster response speeds.

Source
Cursor: Does Cursor require an internet connection to edit code?

While Cursor can open and edit files locally, its AI features including autocomplete, chat, agents, and codebase-aware reasoning require internet access to cloud-hosted models.

Source
Anthropic API: Does the Claude API have different billing models?

Self-serve access uses usage-based tiers with automatic rate limit increases as volume grows. Enterprise customers receive custom rate limits, monthly invoice billing, and hands-on support at negotiated pricing.

Source
Cursor: Can I use Cursor with local models running on my machine?

Cursor can integrate with local models, but requests still route through Cursor's backend for prompt building. True localhost mode without external endpoints is not supported. The paid plan ($20+/month) is required to use local models.

Source
Anthropic API: How much extra does US-only inference cost on the Claude API?

US-only inference costs 1.1x pricing for input and output tokens across all model tiers compared to standard multi-region pricing.

Source
Cursor: What privacy controls does Cursor offer?

Cursor offers Privacy Mode (enabled on paid Team plans) which prevents customer data from being used for model training, with zero data retention agreements with all AI providers. When disabled, Cursor may use codebase data to improve features.

Source
Cursor: What are the differences between Pro and Pro+ plans?

Pro ($20/month) includes unlimited completions and 500 fast premium requests, while Pro+ ($60/month) provides 3x those request limits, priority feature access, and extended Agent capabilities.

Source
Cursor: Does Cursor support SSO and on which plan?

SSO with SAML/OIDC is included on Teams Standard ($40/user/month) and higher plans, with full team administration and audit logs.
