Codex stores images as base64 in logs — 1,200 images ballooned to 12GB
Yamapama · x · 2026-11-13
Follow-up to the earlier complaint: Yamapama found the copies Codex keeps in its sqlite and session log are base64-encoded, about 25% larger than the original jpg/png files. So 1,200 images got stored 4 times — 12GB total.
Since he runs multiple daily backups to different locations, the waste multiplies further. Codex users doing bulk image generation should watch threadhistory and session logs, which cache every generated image as base64.
