Introduction
In an era where AI can write, debug, and reason about code almost as well as human developers, choosing the right AI coding API is crucial. Speed, accuracy, and cost all matter — and new options expand possibilities while lowering expenses.
Criteria for Evaluating AI Coding APIs
Speed
For live coding help inside your IDE, latency can make or break the experience. Faster APIs keep you in flow.
Accuracy & Reasoning
Beyond code completion, the ability to understand context and provide logical solutions is what separates basic models from serious AI coding assistants.
Pricing
Costs vary dramatically. Looking across providers and models helps you avoid budget surprises.
GPT-5 Codex
