ClearML vs ONNX Runtime
A side-by-side editorial comparison of ClearML and ONNX Runtime — release velocity, themes, recent moves, and the top alternatives to consider.
ClearML vs ONNX Runtime: at a glance
What is ClearML?
ClearML is filling in the hyperdataset lifecycle while hardening the SDK against what it loads.
Recent releases pair hyperdataset work with a steady security pass over the SDK's own inputs. 2.1.7 added an opt-out that blocks processing of pickled artifacts via call argument, config key or CLEARML_BLOCK_PICKLED_ARTIFACTS, plus a path-traversal check when import_offline_session extracts a zip; 2.1.6 added integrity-hash verification for pickled DataFrame artifacts; 2.1.8 added a path-traversal check in dataset merging. The hyperdataset API meanwhile keeps accumulating lifecycle operations — tagging, version snapshots, single-call publishing, DataView retrieval, and now entry deletion, metadata get/set, mapping-rule management and an iterator.
What is ONNX Runtime?
ONNX Runtime is dismantling itself into a core plus detachable accelerator plug-ins, CUDA included.
The runtime's accelerators are leaving the main binary. WebGPU went first as a standalone plug-in execution provider, and CUDA — the backend most GPU deployments actually use — followed in August as a separately packaged plug-in that registers with an existing installation and is now the default CUDA implementation. Alongside that, onnxruntime-web has announced the end of WebGL and JSEP with native WebGPU as the only forward path, and the latest patch adds device-free WebGPU compilation so graphs can be transformed and serialized offline with no GPU present.
ClearML vs ONNX Runtime: editorial side-by-side
ClearML
5.0AI-ASSISTANTS
ClearML is filling in the hyperdataset lifecycle while hardening the SDK against what it loads.
◆ Current state
Recent releases pair hyperdataset work with a steady security pass over the SDK's own inputs. 2.1.7 added an opt-out that blocks processing of pickled artifacts via call argument, config key or CLEARML_BLOCK_PICKLED_ARTIFACTS, plus a path-traversal check when import_offline_session extracts a zip; 2.1.6 added integrity-hash verification for pickled DataFrame artifacts; 2.1.8 added a path-traversal check in dataset merging. The hyperdataset API meanwhile keeps accumulating lifecycle operations — tagging, version snapshots, single-call publishing, DataView retrieval, and now entry deletion, metadata get/set, mapping-rule management and an iterator.
◆ Where it's heading
Two things are converging. The hyperdataset API is filling in the operations a dataset abstraction needs before anyone builds on it seriously: create, snapshot, tag, publish, retrieve, iterate, delete. That the newest release is mostly deletion and metadata management says the API is past the demo stage and into the parts people hit in production. Meanwhile the SDK is being treated as something that consumes untrusted input, because in a shared experiment tracker it is: an artifact is a file another user uploaded, and Python's default answer to a pickle is to execute it.
◆ Prediction
Pickle blocking is opt-out today and the notes give no timeline for flipping the default. The clearer near-term threads are Python 2 removal and the f-string migration, both described as work in progress across several releases.
ONNX Runtime
7.5AI-ASSISTANTS
ONNX Runtime is dismantling itself into a core plus detachable accelerator plug-ins, CUDA included.
◆ Current state
The runtime's accelerators are leaving the main binary. WebGPU went first as a standalone plug-in execution provider, and CUDA — the backend most GPU deployments actually use — followed in August as a separately packaged plug-in that registers with an existing installation and is now the default CUDA implementation. Alongside that, onnxruntime-web has announced the end of WebGL and JSEP with native WebGPU as the only forward path, and the latest patch adds device-free WebGPU compilation so graphs can be transformed and serialized offline with no GPU present.
◆ Where it's heading
The direction is decoupling on two axes. Vertically, accelerator support is being pulled out of the core release train so CUDA fixes and new vendor features no longer wait on a core version, with a plug-in ABI carrying version-gated callbacks as the compatibility surface. Horizontally, the core itself is getting lighter — cuDNN and cuFFT made optional, nvrtc unlinked, the CUDA redistributable footprint cut. Note the release numbering does not read chronologically: the 1.28.1 patch shipped after both 1.29.0 and the CUDA plug-in, because the 1.28 line is being serviced in parallel.
◆ Prediction
Expect the plug-in EPs to take over release cadence from the core, with CUDA 12 removed in 1.27 as announced and further backends following WebGPU and CUDA out of the main binary.
