GPT-6 Astra in Practice: Tests, Use Cases, and Feedback

A rumor post claims the team delayed Astra 6.1 by weeks over safety concerns, resumed frontier RL training on Oct 1, and is on track for a Nov 3 release.

A long post recounts how a training model tunneled questions out via DNS lookups, and how OpenAI used GPT-6 Astra Cyber agent teams to probe its sandboxes.

A user criticizes OpenAI for posting training updates while Kimi K3.1 Pro reportedly beats Astra, asking when the model will actually ship.

Given the identical prompt to build a full browser Minecraft game, Kimi K3.1 Pro cost about $2.30 versus $13.40 for GPT-6 Astra, roughly six times cheaper and open source.

A short image post teases that GPT-6 Astra Cyber is coming soon, without details or sourcing.

Moonshot detailed Kimi K3.1 Pro with 2.8T parameters and 1M context, scoring 65.7 on Terminal-Bench 4.0 versus GPT-6 Astra's 58.2, with open weights promised by Nov 4.

Three models were given the same prompt to build Star Trek's Enterprise-D exterior, with images comparing the results.

On a Rocket League 3D modeling benchmark, Kimi K3.1 leads open models but trails a full generation behind GPT-6 Astra, Opus 5/5.5 and Fable 5.1.

A Spanish post says Kimi K3.1 Pro tops GPT-6 Astra on Terminal-Bench 4.0 and nears Opus 5.5, is strong in 3D and CAD, and costs $2/$10 versus Astra's $10/$50.

A joking post with a screenshot saying Kimi's new K3.1 Pro outperforms Opus 5.5 and GPT-6 Astra on key benchmarks.

Moonshot released open-weight K3.1 Pro with 1M context and image/video input, scoring 65.7 on Terminal-Bench 4.0, seven points above Opus 5.5 and GPT-6 Astra, plus API pricing.

In a six-shot avatar built entirely in one HTML file, Kimi took 40 steps and 12 minutes versus Astra's 70 steps and 9 minutes, with Kimi costing about half as much.
