What Spectral Labs does
Spectral Labs is a San Francisco–based spatial intelligence company founded in 2022 that builds foundation models for engineering design of physical systems. Its flagship product, SGS-1, launched September 15, 2025, is described as the first generative model for structured CAD: given an image, sketch, or 3D mesh as input, it outputs fully manufacturable, parametric B-Rep geometry in STEP format that engineers can directly edit inside established CAD software such as Fusion360. The model supports assembly-context generation (producing feasible parts for partial CAD assemblies from text and image prompts) and STL/mesh-to-STEP reverse engineering, and is benchmarked as outperforming GPT-5 thinking and HoLa B-Rep on a 75-image parametric geometry benchmark.
The company's technology is a custom AI architecture trained on proprietary CAD data, rather than a wrapper on general-purpose multimodal LLMs. The team is intentionally small (1–10 people) and is composed of applied AI researchers and engineers from Autodesk Research, Meta, Samsung Research, and Carnegie Mellon University, including founders who previously built generative design products at Autodesk and founded quantitative trading firms. Spectral Labs has stated it will release its own CAD dataset to the research community to seed ecosystem adoption.
Commercially, Spectral Labs operates a hybrid product-led and direct-sales motion. SGS-1 is exposed as a free research preview on HuggingFace Spaces for self-serve evaluation, while enterprise deployments and research collaborations are handled via a Typeform contact form. Pricing is not publicly disclosed, and no paying customers, ARR, or contract values have been announced. To date, the company has disclosed only one funding round, led by Soma Capital in 2024, and has no publicly listed institutional investors, parent company, or partnerships.

Spectral Labs product offering
Product offeringCore offering
Spectral Labs builds and licenses SGS-1, a generative AI foundation model that produces fully manufacturable, parametric B-Rep 3D CAD geometry in STEP format from inputs such as images, sketches, or 3D meshes. The offering enables mechanical engineers and CAD designers to rapidly generate editable CAD geometry, convert mesh files to parametric STEP files, and create new parts within existing assembly contexts, addressing gaps in spatial understanding left by existing foundation models.
Product overview
Spectral Labs is a spatial intelligence company building foundation models for physical engineering design. The company's primary product is SGS-1, the first generative model for structured CAD that can generate fully manufacturable and parametric 3D geometry. SGS-1 takes inputs such as images, 3D meshes, or sketches and outputs parametric B-Rep CAD files in STEP format that can be edited in traditional CAD software. The model represents a breakthrough in the complexity/editability tradeoff for CAD generation, outperforming existing methods like B-rep diffusion models and VLMs.

Products and services
- SGS-1 A foundation model for structured CAD that generates fully manufacturable and parametric 3D geometry from images, sketches, or 3D meshes. SGS-1 outputs B-Rep CAD geometry in STEP format that engineers can edit in traditional CAD software such as Fusion360. The model supports image-to-CAD, sketch-to-CAD, and STL/mesh-to-STEP conversion as well as assembly-context generation. Available as a research preview on HuggingFace Spaces for evaluation and experimentation.
Quantifiable outcome
- SGS-1 outperforms GPT-5 thinking and HoLa B-Rep, achieving at least one success for all but the most complex objects on a benchmark of 75 images depicting medium to high complexity parametric geometry.
