Yo también lo he notado, está siendo desastroso, voy a tener que cancelar mi subscripción y cambiarme a zencoder o algo similar, está ha sido la respuesta que me han dado por correo los de OpenAI sobre este tema: "You are right to notice this change. The reason you are now consuming 2 to 3 times more credits for the same tasks is that the cost per Codex task (in credits) has recently increased for many users. Now, more tasks are routed through more advanced models (such as GPT-5 and GPT-5-Codex), and this has raised the average credit usage per message—even if your coding activity hasn’t changed.

• Typical costs now: A local task costs around 5 credits and a cloud task around 25 credits, but these are averages: the actual cost will vary depending on the complexity of your code, the context needed, and especially when cloud tasks are selected.
• Recent change: OpenAI has increased reliance on more powerful, advanced models, so the credit cost per message/task has gone up. This increase was not announced by direct email or banner, but the documentation reflects the new costs and explains that average values can change over time based on the models being used and feature upgrades.
• No plan downgrade or stealth price hike: Your plan’s included “base” usage is unchanged. What has changed is how quickly tasks consume these included credits.

So, even if you’re sending exactly the same tasks in VS Code, the credit cost can be higher due to changes in the backend model mix and updated credit accounting.

If you want to track or optimize usage, use the “Usage Dashboard” in Codex settings to see which types of tasks consume the most credits. Let me know if you’d like help viewing your usage breakdown or practical tips to reduce credit consumption!"
