SemExp
No estimate
No hardware requirements for this model
This model's weights are open, but no parameter count has been published for it. Every memory and speed figure starts from that number, so we would rather show nothing than a fabricated estimate.
On record
Full specification
Everything on record for this model. Most of it describes how it was trained rather than how it runs — useful context for judging how much work went into it, and how it compares with models built at a different scale.

- Reinforcement learning
Size
How large the model is and how much data it was trained on. Parameters are the figure that decides whether it fits on a given graphics card.
- Training data
- tokens
"Our training and test set consists of a total of 86 scenes (25 Gibson tiny and 61 MP3D) and 16 scenes (5 Gibson tiny and 11 MP3D), respectively"
Availability
Whether you can obtain the model and run it on your own hardware, which is what decides if any of the graphics-card figures on this page apply.

What the numbers mean
Background
SemExp was published by Carnegie Mellon University (CMU),Facebook AI Research, in the country recorded as United States of America, during July 2020. The publishing organisation is categorised as academia,Industry.
It works in the domain of Robotics, and is recorded as performing the task of object detection.
The weights are published, so it can be downloaded and run on your own hardware indefinitely, offline, with no account attached.
How it was trained
It is tracked in the underlying dataset for one reason in particular: sOTA improvement.
Answers
SemExp — common questions
SemExp— is it open source?
Its weights are published, so it can be downloaded and run on your own hardware. Note that open weights is not the same as open source in the full sense — it says nothing about the training data, the training code, or the commercial terms attached.
SemExp— how many parameters does it have?
No parameter count has been published for it, which is why no memory or speed figure appears on this page.
SemExp— who created it?
It was published by Carnegie Mellon University (CMU),Facebook AI Research, based in United States of America, an organisation categorised as academia,Industry.
SemExp— when was it released?
It was published in July 2020. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
SemExp— what is it used for?
It works in the domain of Robotics, and is recorded as handling the task of object detection. A model can carry several of each, so these are the areas it was built for rather than a limit on what it will attempt.
SemExp— where can I download it?
The weights are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.
SemExp— what GPU do I need to run it?
We cannot say. It has open weights, but no parameter count has been published for it, and every memory and speed calculation starts from that number. We would rather show nothing than a fabricated estimate.
The other direction
Looking at it from the other side?
This page starts from the model. If you already own a card and want to know everything it will run, start from the hardware instead.
