OpenAI says GPT-5.6 Sol achieved a new state-of-the-art result on the Terminal-Bench 2.1 command-line benchmark
Story Overview
OpenAI's newest GPT-5.6 Sol flagship posted a fresh high on Terminal-Bench 2.1, an open benchmark that throws realistic CLI jobs at models and scores how well they plan, iterate, and juggle tools inside a sandboxed terminal. The Sol Ultra variant hit 91.9 percent, nudging past Claude Mythos 5, while the rest of the GPT-5.6 family (Terra and Luna) also appeared on the leaderboard. Access stays restricted to roughly twenty partner organizations for now.

Developer Impact
Real-world coding tasks just got a sharper benchmark
Terminal-Bench 2.1 stresses long-horizon workflows such as software engineering, sysadmin chores, and data pipelines, all inside reproducible sandbox environments. The 91.9 percent score shows measurable headroom in agent-style command-line coordination, yet every number still comes from OpenAI-run evaluations.
Policy Risk
Wider release still waits on regulatory review
A June executive order requires federal safety checks before frontier models spread further, so the current limited preview has no announced end date. Pricing tiers and new prompt-caching features are listed, but exact availability for most developers remains unknown.
Sentiment
Positive users praise GPT-5.6 Sol's new Terminal-Bench 2.1 record for strong coding results, while negative users doubt the claims since the model remains unreleased and the benchmark feels saturated.

GPT-5.6 is a capable model, especially for long-horizon tasks and knowledge work across coding, computer use, and science. I’m grateful to have had the chance to contribute and to “distill” from the amazing teammates who helped make it possible!

@yacineMTB If you want to use the model any time soon, you are sol.

@yacineMTB Openai is giving their models names now? Sol/Terra/Luna is a good trio

@yacineMTB If you are feeling pressure. It is a good sign.
No need to kneel. Just the willingness to know when to do so ❤️

@joshhfm @yacineMTB If the chinese models are legit better than this by the middle of July I'll eat a sock.

@Tsucks6432 @yacineMTB why don't you think it's possible? there are open source chinese models already outbeating mythos

@yacineMTB At these these frontier labs are going with all this circus, we gonna have better open source models before we get their best ones lmao

@yacineMTB If kneeling paid the budget, we’d all be on our knees by now.

@yacineMTB they are raigebaiting now, publishing such state of the art benchmark while we pesky little ones are not allowed to touch it.

@yacineMTB cool, another model which the normal user won't get until chinese open source models are better anyway

@yacineMTB Yaciiine you're just gonna complain about how bad Sol's code is anyway 🙄

@yacineMTB very scary indeed. It may be able to chain an exploit using ls, cd, and cat
