The author asked Astra to rebuild OG Fortnite, walked away for two hours, and returned to find trees, chests, and cars all in their original positions, calling it the future.

A user says Astra Ultra converted nTopology implicit geometry into a ray-traced Blender render with an alumina material, for a fusion device prototype.

The poster shared SVG output from Astra and said SVG generation is essentially solved, marking the start of a new era.

The user asks why OpenAI won't offer at least Light and Medium Astra tiers to Plus users in Chat, given Astra's higher token efficiency.

The author suggests replicating a demo with Astra medium and a /goal for proof, then switching to max to polish iteratively, separating building from tuning.

The release lets restarts resume where they left off, speeds up long chats, and adds support for GPT-6 Astra and Muse Spark 1.3.

A source says OpenAI is developing multiple GPT-6 variants, though naming and positioning remain unclear, and Astra is not the end of the line.

A Japanese test gives Astra an image and asks it to recreate the 3D scene as closely as possible using Blender CLI and Blender MCP, with input and output comparisons.

The author launched an overnight GPT-6 Astra Ultra task to clean dead code, factor out redundant code and remove duplicate helpers, and shared the full prompt.

A roundup covering Astra's rollout to all Plus and Business users, internal use pulling OpenAI's roadmap forward six months, a new cross-context memory method, plus Claude, Gemini and Anthropic IPO news.

Japanese blogger npaka wrote a note on how much GPT-6 Astra has improved at Blender 3D work compared with earlier models.
