Day 22: Tibo announces GPT-6.1 Terra, a model he says gives 2X more usage than 6.1 Sol across the API and subscriptions

Tibo writes: "Day 22/ Terra is back! Our first model that is significantly better at writing, personality and nuanced understanding of requests. Packs a punch across the board, very good at computer use, and gives 2X more usage than 6.1 Sol across API and subscriptions." It was posted at 18:06 UTC on 26 October, within Day 22, quoting OpenAI's announcement: "GPT-6.1 Terra: delivering fast and capable computer use at a lower price."

Read the whole note

This is a new model release, not a usage reset and not a change to the stated plan limits. By Tibo's account, choosing Terra instead of 6.1 Sol makes the same allowance go about twice as far; the post does not say whether Terra is the default in Codex, which plans get it, or how it compares with Sol on coding. The 2X figure is his, not a benchmark.

To check it, select GPT-6.1 Terra in Codex or ChatGPT and compare how much of the allowance a similar task consumes against 6.1 Sol. Rantr has not independently verified this.

Method

How this record is made

Each day runs from 00:00 to 24:00 UTC. The record counts votes, release check answers, experiences, “Same here” and replies timestamped inside the day. When the day closes the record is frozen; it is recomputed only after an entry in the public corrections log, or when the day’s update is recorded late. Rantr is a neutral record: it does not take a side.
