How good are agents actually at CAD? Today we release CADBench, evaluating 10 Models on 105 realistic tasks in Fusion 360 Fable 5 and Gemini 3.7 Flash are #1 with only 24.6% pass rate

Continuing my series on CAD AI: Here Gemini 4 Argon is supposed to build a base for a given DAMIAO 4340 actuator. It uses coding exclusively and finishes after 263 steps with a reward of 0.459 mostly because of missing wire openings

Starting a new series where I show the latests models' performance on different real-world tasks in Engineering The first one is GPT-6.1 trying to reconstruct the graph on the right in AutoCAD. It took 181 steps and got a reward of 0.414

Our Co-Founders @PascalBtd and @atoof_sh sat down on the Europe on Edge podcast and talked about the current state of multimodal AI and the company's mission. If this mission resonates with you, have a look at our open job listings (links are below).

New SOTA on CADBench: Gemini 3.8 Flash. 30% pass rate on 105 expert-authored CAD tasks in Autodesk Fusion, up from 24.6% for Gemini 3.7 Flash. Muse Spark 1.3 also improves its mean verifier score by 54% over 1.2, though full task completion remains a challenge.

Muse Spark 1.3 improves despite pass rate staying at 0%: • Mean verifier score: 13.44 → 20.66 (+54%) • Average runtime: 60.8 → 23.8 minutes (61% shorter) • Valid tool calls: 76.8% → 93.0% Better intermediate results and faster runs, but full task completion remains unsolved.

Can computer-use agents use complicated graphical software? You’re watching GPT-5.6 Sol operate Autodesk Fusion for 250 turns as it attempts a real mechanical-design task. The run is part of a benchmark aimed at the question "how good are agents at CAD?" @seldon_tech's CADBench contains 105 mechanical-design tasks tested across 10 frontier models, and the results show how early reliable, autonomous CAD work remains: More than two-thirds of the tasks are still unsolved. That gap matters as agents make their way into the professional tools used to design the physical world. Getting around Autodesk Fusion is one thing, but producing a correct, editable model an engineer can pick up and use is much harder. CADBench gives us a way to see and measure that frontier. Great work from the Seldon team! Explore CADBench: seldon.global/blog/cadbench

Infinibench-v0: part of the benchmark was created by a continuously exploring agent, rewarded for identifying new failure modes in VLMs. It produces non-trivial, out-of-distribution problems — trivially easy for humans, yet SOTA VLMs fail — and diagnoses failure modes that were previously unknown.

Introducing VGI-Bench: a multimodal, holistic benchmark probing 12 distinct visual and audio-visual skills. 550 human-curated questions, designed to mitigate the common mistakes in today's video benchmarks and expose pragmatic failures of state-of-the-art models. Best model: 64.73%. Humans: 84.5%.

Our dataset consists of 398 public videos and programmatically generated videos, the latter to avoid models having been exposed to the test data at train time, spanning just under 100 hours.
