AI coding assistants in 2025 — speed, context, and cost compared
We re‑tested the top coding assistants with large repos, long instructions, and strict JSON tasks. Here’s who’s fastest and most reliable.
How we tested
- Large repo nav: jump to definitions, create safe edits, respect lint rules.
- Long instructions: multi‑file changes with summaries.
- Strict JSON tasks: transform data and preserve schema.
Leaders
- Assistant A — best at repo‑scale edits with minimal errors.
- Assistant B — fastest latency, slightly weaker on lint adherence.
- Assistant C — cheapest for continuous usage, strong JSON fidelity.
Buying advice
- If you work in monorepos, pick the best at cross‑file reasoning.
- If latency bothers you, pay for the faster tier.
- For teams, enforce org‑level policies and redact secrets.
