OpenAI to Merge ChatGPT and Codex Token Allowances in December 2026
OpenAI is merging the token allowances for ChatGPT and Codex for its Plus, Pro, and Business plans in December 2026. This change will affect how users budget their usage, as Codex work will now use the same allowance as ChatGPT. The integration aims to better reflect the computational demands of different tasks, particularly for advanced models such as GPT-6. The move is part of a broader pricing overhaul that began in April 2026 with token-based usage pricing.
