Processing 50,000 lines of code (~510,000 tokens) with GPT-5.3 Codex costs $0.8925 for codebase ingestion and $2.321 for an AI-powered code review and refactoring pass.
Quick answer
A 50,000 lines of code codebase is estimated at 510,000 tokens for GPT-5.3 Codex. Ingestion costs $0.8925; a review and refactoring pass with roughly 20% output costs about $2.321.
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.
Feed 50,000 lines of code into the prompt context for repository search, Q&A, or architecture planning.

On average, code yields approximately 10.2 tokens per line in GPT-5.3 Codex (o200k_base tokenizer). Indentation, brackets, camelCase variable names, and comments slightly increase token density compared to plain English text. 50,000 lines of code produces approximately 510,000 tokens.
Sending 50,000 lines of code as context and generating a thorough code review with recommendations costs approximately $2.321. Utilizing prompt caching on repeat turns or static repository definitions drops this to $1.517.
GPT-5.3 Codex has a context window of 256,000 tokens. 50,000 lines of code consumes 199.22% of its total available context.
