OpenAI Codex Head Tibo Announces Default Speed Optimization of GPT-6 Astra and GPT-6.1 Sol by About 50%
OpenAI Codex head Tibo announced that the default speed of GPT-6 Astra and GPT-6.1 Sol has been optimized by about 50%. This applies to subscription users and products and partners logged in with ChatGPT accounts, including OpenCode, Pi, Amp, and Devin. Users do not need to change settings and should feel the difference within two hours.
He later added that throughput has increased from 30 TPS to 50 TPS, stating that the most optimized tokenizer has been used. The number of tokens required for these two models to complete tasks is also lower. The post did not provide benchmark tests, price changes, or capacity limits.
This is the first day of his 28-day plan. The day before, he mentioned that over the next 28 days, he would either deliver a clear improvement to most Codex and office users daily or reset the entire project. Speed was the first item, with no reset.
The speed increase refers to the default speed, not new models. Astra and Sol are included in this range. The path goes through subscriptions and ChatGPT logins, so partners do not need to release separate versions. The increase from 30 TPS to 50 TPS is about a 67% increase in throughput, but he maintains that it is about 50% faster for users. Both figures come from his post, with no third-party retesting.
The tokenizer was specifically mentioned. Faster generation combined with fewer tokens will shorten the wait time for a coding task. He did not mention whether reasoning quality, tool invocation, or long context has also sped up.
This is a release of reasoning capacity, not a price reduction. Buyers are those using Codex by subscription and coding tools that embed ChatGPT login into their products, while the seller is OpenAI, providing reasoning for Astra and Sol. The event is driven by the default speed switch, not user migration. Similarly, subscriptions can achieve higher throughput within two hours. Beneficiaries are partners who have integrated login and retain users by reducing wait times, while those still experiencing 30 TPS without this default optimization are under pressure.

Tibo has incorporated improvements into a daily delivery over 28 days, with speed chosen as the first item rather than new features. The simultaneous announcement of default speeds for GPT-6 Astra and GPT-6.1 Sol indicates that the optimization is at the service layer, not within a single product interface. ChatGPT login is framed as a channel, allowing OpenCode, Pi, Amp, and Devin to avoid individual integrations. The increase from 30 TPS to 50 TPS is the throughput figure he provided, with about 50% being the speed increase users can feel.
No new announcements regarding computing power have been made. The same subscription covers more tokens per second, and the tokenizer reduces the number of tokens needed to complete tasks. The capital implication is a decrease in unit wait time, allowing coding agents to run more tool invocations within the same subscription. Partners receive the default switch, not separate capacity contracts. Those who have already used ChatGPT login will experience this within the two-hour window.
A comparison can be made to cloud computing, which enhances instance performance through backend switches rather than requiring users to download patches as in the 2000s. Editors like Cursor later also retained users by reducing model wait times. Tibo is currently in a phase of controlling the experience: the model names remain unchanged, but the default throughput has changed, and the 28-day reset threat is used to ensure daily perceptible improvements.
Structurally, this represents a shift in pricing power. The difference in coding tools used to lie in who accessed the model; now there is an additional layer of who gets the default speed first. The mechanism is that the login protocol pushes the optimization to multiple products at once. Throughput has changed from 30 TPS to 50 TPS, and wait times are being rewritten by the platform, with no versions to release on the application side.

Once the default speed changes, all integrated products change together.
Fewer tokens, combined with faster output, truly shortens wait times.
Even without releasing new models, it can rewrite the product experience of others.
