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

The author predicts OpenAI will bring Dots to Plus powered by GPT-6.1 Terra, arguing Terra is cheap and fast but weaker than Astra, which stays Pro-only.

A Codex user claims GPT-6 Astra only drains tokens quickly, says Sol High and Terra perform better in testing, and recommends switching to Sol Medium/High.

A user expects GPT-6.1 Luna to arrive before Tibo's 28-day challenge ends and hopes OpenAI saves GPT-6.1 Astra for the final day to beat Claude Opus 5.5.

Given the same prompt for a desert mechanical centipede, Opus 5.5 shows more detailed armor panels and joints, while Astra's design is simpler and less consistent across angles.

A user working on BIM-to-2D-drawing conversion says GPT-6 Astra got stuck in deliberation until prompted to revisit the modeling approach, after which the base and main facade took shape.

A Codex user asks whether GPT-6.1 Terra is genuinely better than GPT-6 Astra at coding or just overhyped.

A user reports GPT-6.1 Terra matches GPT-6 Astra at one-tenth the price and finishes tasks about 3x faster than Astra and Sol.

The post maps Astra to high performance at high price, Sol to all-round mid-price, Terra to speed and low cost, and Luna to value, asking what a merged model could do.

The post breaks down Terra: 50% lower API prices, better screen understanding and cross-app actions, Astra-level Agents' Last Exam, 3x faster than Astra and Sol; Sol or Astra still recommended for complex coding.

Researchers had GPT-6.1 Sol, GPT-6 Astra and Opus 5.5 each build and train a dedicated Hearthstone AI; after 20 days it hit 91% decision accuracy and outranked the server's top 10, while asking Astra directly scored only 63%.
