Frequently Asked Questions
Which AI coding assistant has the best free tier in 2025?
Gemini Code Assist offers the most generous free tier with 180,000 monthly completions (6,000 per day) plus 240 chat requests - that's 90x more than GitHub Copilot's 2,000 monthly completions. Gemini includes Agent Mode at no extra cost, with 128K context in the free tier (1M context in paid tiers), making it perfect for students, learners, and side projects.
Is Cursor worth the higher price compared to Copilot?
Cursor's premium pricing ($20-60/month vs Copilot's $10/month) can be justified by productivity gains. User reports suggest significantly faster feature implementation and reduced boilerplate time due to superior codebase awareness. For professional developers working on complex codebases, these time savings often exceed the cost difference. Calculate ROI based on your hourly rate - if Cursor saves you 5+ hours monthly, it pays for itself.
Can I use multiple AI coding assistants at the same time?
Yes, many professional developers strategically use multiple tools. Common combinations include: Gemini's free tier for side projects, GitHub Copilot for GitHub workflow integration, and Cursor for complex refactoring work. The tools complement rather than compete, as each excels in different scenarios. However, using multiple paid tiers simultaneously may not be cost-effective for individuals.
Which tool is best for large enterprise codebases?
For large codebases, Cursor leads with superior repository-wide context awareness and multi-file refactoring (85% success rate). However, GitHub Copilot Business offers the best enterprise value at $19/user/month with IP indemnity, team management, and compliance features. Gemini's 1M context window handles massive codebases well, but costs $45/user/month for Enterprise features. Choose based on whether you prioritize technical capability (Cursor) or cost/compliance (Copilot).
Do AI coding assistants actually make developers faster?
It depends on experience level. A rigorous METR study (July 2025) found that experienced open-source developers took 19% longer using AI tools despite believing they were 20% faster. Separate studies have shown newer developers can achieve productivity gains with tools like GitHub Copilot. The key is using AI tools appropriately - they excel at boilerplate, documentation, and suggesting patterns, but can slow down complex architectural decisions that require deep thinking.
Which AI coding assistant has the best model selection?
GitHub Copilot offers the widest model selection with GPT-5 Pro, Claude Opus 4, OpenAI o3, and custom models (Enterprise tier). Cursor provides access to 25+ LLMs including GPT-5, Claude 4, Gemini, DeepSeek, and xAI Grok. Gemini Code Assist focuses on its own Gemini 2.5 Flash and Pro models, with custom models available in Enterprise tier. If model flexibility is critical, choose Copilot Pro+ ($39/month) or Cursor.
