Recent discussions have surfaced conflicting numbers about GPT-5.6 Sol's context window, with some sources citing 1.05M tokens and others 258K. This post breaks down the discrepancy, explaining that the larger figure likely refers to a different configuration or model variant, while Codex may have its own context limits. For developers building applications that rely on long-context processing, understanding these specs is crucial for model selection and cost optimization. The clarification helps avoid surprises when deploying AI solutions that require extensive context handling.
