Dates follow US Pacific time (PT). Counts are per day; features and resets can overlap. Reset-related days include banked-reset announcements.
- DAY 1Feature
Subscription access gets about 50% faster generation
The GPT-6 Astra and GPT-6.1 Sol change includes partner tools using ChatGPT sign-in. Faster generation is separate from a larger usage allowance.

Instant steering and GPT-6.1 Sol Ultrafast

Shared context, longer caching and routing changes reduce repeated processing in Codex and Work. Benefits depend on what a task can reuse.

Usage reset confirmed at 21:12 UTC
An end-of-day expectation was followed by public confirmation on the same Pacific date. Keep the announcement, timing reply and completion together.

Codex broadcast followed by a reset message

Tibo’s plan was to ship an update with a clear benefit for most Codex / Work users, or perform a full usage-limit reset, every day for 28 days. This calendar starts with Day 1 on October 5, 2026, in US Pacific time, and ends on November 1.
How dates and categories are recorded
Open a day to read its changes, conditions, original posts and relevant questions. “Covered” means an individual article is available. Day 3 remains a banked-reset announcement; Day 15 is classified as a broadcast and reset. Later days will receive articles when their updates can be verified.
Calendar dates follow US Pacific time (PT), including daylight saving changes. Daily articles separately list important post times in UTC. Lists and article headers use the calendar’s series date; this index uses the plan’s start date. Day 9 retains the distinction between the post’s last edit time and its original publication time.
