## Frequently Asked Questions

### What is the highest-scoring AI coding agent in 2026?
OpenCode (94.5/100) and Cursor (94.0/100) lead our 2026 empirical index. OpenCode wins for terminal/LSP open-source workflows with zero seat markup, Cursor wins for sub-45ms visual multi-tab IDE autocomplete, and Claude Code (93.0/100) leads autonomous multi-file SWE-bench Verified resolution at 76.8%.

### Which AI coding agent has the lowest token cost per edit?
Aider achieves a 68% reduction in prompt token consumption by transmitting a compact tree-sitter AST symbol graph rather than raw full-file contents, and pairs cleanly with a LiteLLM 45% cost router.

### Is Cursor or Windsurf better for large multi-file repositories?
Cursor leads on raw single-file tab prediction latency (<45ms), whereas Windsurf Cascade maintains a 32% lower RAM footprint (<1.4GB) and deeper automatic terminal-to-editor context tracking at $15/month.
