Processing 250 lines of code (~2,550 tokens) with o4-mini costs $0.002805 for codebase ingestion and $0.005049 for an AI-powered code review and refactoring pass.
Quick answer
A 250 lines of code codebase is estimated at 2,550 tokens for o4-mini. Ingestion costs $0.002805; a review and refactoring pass with roughly 20% output costs about $0.005049.
Method & trust
Code is estimated at a tokenizer-specific tokens-per-line ratio, then priced separately for repository context and generated review output. Comments, minified files, tests, and repeated context can materially change the bill.

On average, code yields approximately 10.2 tokens per line in o4-mini (o200k_base tokenizer). Indentation, brackets, camelCase variable names, and comments slightly increase token density compared to plain English text. 250 lines of code produces approximately 2,550 tokens.
Sending 250 lines of code as context and generating a thorough code review with recommendations costs approximately $0.005049. Utilizing prompt caching on repeat turns or static repository definitions drops this to $0.002945.
o4-mini has a context window of 256,000 tokens. 250 lines of code consumes 1.00% of its total available context.
