Anthropic's Claude Sonnet 4.6 boasts a 200,000 token context window, which equates to roughly 500,000 characters of raw code. But what if you need to analyze a 1.5 million character repository?
By converting your source code into dense PNG atlases using PXINK, you effectively multiply the capacity of that 200K window. Claude's vision encoder reads the pixel data flawlessly, allowing you to cram over 2.5 million characters of code into a single prompt.
Incredibly well. Sonnet 4.6 was specifically trained on complex multi-document OCR and chart analysis. It can effortlessly correlate variables and function calls across dozens of encoded image pages.
While Opus 4.8 offers slightly deeper reasoning, Sonnet 4.6 is significantly faster and cheaper. For 95% of codebase analysis and code generation tasks, Sonnet 4.6 is the optimal choice.
