GPT-6 Astra and GPT-6.1 Sol Subscription Defaults Get About 50% Faster

Published by CodexBro · 2026-10-06 (UTC)

OpenAI Codex lead Tibo announced on October 5, 2026 that GPT-6 Astra and GPT-6.1 Sol are now optimized to be about 50% faster by default when used through a ChatGPT subscription, across OpenAI products and partners that support Sign in with ChatGPT. Users do not need to change settings, and OpenAI said the improvement should become noticeable within roughly two hours of the announcement. The announcement does not state a change to usage-limit rules; this delivery is a performance improvement, not a full reset.

Tibo presented this as Day 1 of the 28-day plan: the subscription default for GPT-6 Astra and GPT-6.1 Sol is about 50% faster across OpenAI products and supported Sign in with ChatGPT partners such as OpenCode, Pi, Amp, and Devin. He later described the target as roughly 50 TPS instead of 30 TPS and highlighted tokenizer and token efficiency. The public announcement does not specify the underlying inference-infrastructure or scheduling changes, and it does not announce any change to plan allowances, five-hour or weekly windows, multipliers, or credits. This Day 1 delivery is therefore a performance update, not a global reset, banked reset, or extra credits.

No separate rollout-completion time was published.
