GPT-6 Astra and the future of BIM modelling

Excerpt from AEC Magazine

AI has made a significant leap forward in working with 3D geometry. Open AI’s latest model, GPT-6 Astra, can turn drawings, photographs and instructions into 3D models. For AEC, the bigger question is how this capability will fit into a design process in which almost everything is subject to change, writes Martyn Day There is something disconcerting about watching software attempt work that has occupied professionals for decades. Give Open AI’s new GPT-6 Astra model references of building, connect it to 3D modelling software and leave it to work, and geometry appears, sometimes looking more resolved than it is. Models once built object by object can now be attempted through conversation or uploaded drawings. Experiments by architects with ChatGPT Astra deserve attention. A general-purpose AI can interpret references, plan modelling operations, write code, inspect the result and make corrections.

Trimble embeds AI across AECO
Trimble Connect platform introduces AI agents and automation to improve project coordination, manage risk and streamline workflows Trimble has embedded AI within Trimble Connect , expanding the platform beyond its traditional role as a common data environment (CDE) to connect site information with design, cost and operational workflows. The new capabilities are intended to help teams identify and mitigate risks across the project lifecycle, while keeping human judgement at the centre of decision-making. Unveiled at Trimble’s Dimensions User Conference, the AI capabilities span design, construction and project operations. In design, they include generating architectural options using live as-built point-cloud data, converting natural-language prompts into constructible structural models, and automatically classifying scanned point clouds into structural elements. For construction teams, applications include AI-powered diagnostics for machine-control systems, converting 360-degree site walk videos into 3D point clouds, and voice-driven site inspections that automatically transcribe observations and link them to project drawings.

G2 Digital launches quad-GPU 2U server
UK-manufactured 2U Q-Power offers firms an on-premise alternative to premium cloud AI services G2 Digital, a UK specialist in custom-built rack-mount computers, has launched the 2U Q-Power, a high-performance GPU server designed for complex AI workloads and rendering. The system can accommodate up to four dual slot Nvidia RTX GPUs, offering twice the capacity of most conventional 2U servers and greater computing density within a rack. This is made possible by a custom chassis design that mounts the GPUs horizontally, parallel to the motherboard. When configured with four Nvidia RTX Pro 6000 Blackwell Max-Q GPUs, the Q-Power delivers 384 GB of combined GPU memory, enabling organisations to run demanding AI workloads entirely on-site. This includes large language models (LLMs) with 70 billion parameters at full precision, as well as significantly larger models using lower-precision formats and quantisation.

AI companies are offering architects six figures for CAD files; have you been approached?
Artificial intelligence companies are turning to architects and other AEC firms in search of data. As tech enterprises seek to build AI models and agents to perform industry-specific tasks, such as reviewing drawings and writing RFI responses, architecture firms are being approached by businesses offering money in return for access to private data. “Architects, have you seen this?” asked USC adjunct professor Simon Ha in a LinkedIn post . “This AI company is offering to pay six figures for your CAD files, including revisions and markups, to train AI models on how design work gets done.” Ha’s post included a screenshot of a social media post by a company, Nyne.ai, describing itself as “the data factory for AI,” which said, “You’ve got 3 years of CAD files doing nothing. We’ll pay you six figures for them.” “This raises serious questions about copyright and ownership of instruments of service,” Ha added.
