Codex Burns Tokens in Endless Compression Loops
bdsqlsz · x · 2026-07-19
A post highlights that Codex burns through tokens during long tasks due to a flawed compression design. Once compressed, the model only sees the initial prompt, trapping it in an endless loop of "initial prompt → compression → execution". It can only break the cycle if compression randomly skips, otherwise, it drains the entire quota.
An accompanying visual illustrates this runaway loop: compressing the context repeatedly resets the working memory, causing redundant executions and massive token waste. The poster tagged relevant developers to review the issue.
