Provided files, and GPTQ parameters
Multiple quantisation parameters are provided, to allow you to choose the best one for your hardware and requirements.
Each separate quant is in a different branch. See below for instructions on fetching from different branches.
All recent GPTQ files are made with AutoGPTQ, and all files in non-main branches are made with AutoGPTQ. Files in the main branch which were uploaded before August 2023 were made with GPTQ-for-LLaMa.
Explanation of GPTQ parameters
- Bits: The bit size of the quantised model.
- GS: GPTQ group size. Higher numbers use less VRAM, but have lower quantisation accuracy. "None" is the lowest possible value.
- Act Order: True or False. Also known as
desc_act. True results in better quantisation accuracy. Some GPTQ clients have had issues with models that use Act Order plus Group Size, but this is generally resolved now. - Damp %: A GPTQ parameter that affects how samples are processed for quantisation. 0.01 is default, but 0.1 results in slightly better accuracy.
- GPTQ dataset: The calibration dataset used during quantisation. Using a dataset more appropriate to the model's training can improve quantisation accuracy. Note that the GPTQ calibration dataset is not the same as the dataset used to train the model - please refer to the original model repo for details of the training dataset(s).
- Sequence Length: The length of the dataset sequences used for quantisation. Ideally this is the same as the model sequence length. For some very long sequence models (16+K), a lower sequence length may have to be used. Note that a lower sequence length does not limit the sequence length of the quantised model. It only impacts the quantisation accuracy on longer inference sequences.
- ExLlama Compatibility: Whether this file can be loaded with ExLlama, which currently only supports Llama models in 4-bit.
| Branch | Bits | GS | Act Order | Damp % | GPTQ Dataset | Seq Len | Size | ExLlama | Desc |
|---|---|---|---|---|---|---|---|---|---|
| main | 4 | 128 | Yes | 0.1 | wikitext | 4096 | 7.26 GB | Yes | 4-bit, with Act Order and group size 128g. Uses even less VRAM than 64g, but with slightly lower accuracy. |
| gptq-4-32g-actorder_True | 4 | 32 | Yes | 0.1 | wikitext | 4096 | 8.00 GB | Yes | 4-bit, with Act Order and group size 32g. Gives highest possible inference quality, with maximum VRAM usage. |
| gptq-8--1g-actorder_True | 8 | None | Yes | 0.1 | wikitext | 4096 | 13.36 GB | No | 8-bit, with Act Order. No group size, to lower VRAM requirements. |
| gptq-8-128g-actorder_True | 8 | 128 | Yes | 0.1 | wikitext | 4096 | 13.65 GB | No | 8-bit, with group size 128g for higher inference quality and with Act Order for even higher accuracy. |
| gptq-8-32g-actorder_True | 8 | 32 | Yes | 0.1 | wikitext | 4096 | 14.54 GB | No | 8-bit, with group size 32g and Act Order for maximum inference quality. |
| gptq-4-64g-actorder_True | 4 | 64 | Yes | 0.1 | wikitext | 4096 | 7.51 GB | Yes | 4-bit, with Act Order and group size 64g. Uses less VRAM than 32g, but with slightly lower accuracy. |
How to download, including from branches
In text-generation-webui
To download from the main branch, enter TheBloke/Synthia-13B-v1.2-GPTQ in the "Download model" box.
To download from another branch, add :branchname to the end of the download name, eg TheBloke/Synthia-13B-v1.2-GPTQ:gptq-4-32g-actorder_True
From the command line
I recommend using the huggingface-hub Python library:
pip3 install huggingface-hub
To download the main branch to a folder called Synthia-13B-v1.2-GPTQ:
mkdir Synthia-13B-v1.2-GPTQ
huggingface-cli download TheBloke/Synthia-13B-v1.2-GPTQ --local-dir Synthia-13B-v1.2-GPTQ --local-dir-use-symlinks False
To download from a different branch, add the --revision parameter:
mkdir Synthia-13B-v1.2-GPTQ
huggingface-cli download TheBloke/Synthia-13B-v1.2-GPTQ --revision gptq-4-32g-actorder_True --local-dir Synthia-13B-v1.2-GPTQ --local-dir-use-symlinks False
More advanced huggingface-cli download usage
If you remove the --local-dir-use-symlinks False parameter, the files will instead be stored in the central Huggingface cache directory (default location on Linux is: ~/.cache/huggingface), and symlinks will be added to the specified --local-dir, pointing to their real location in the cache. This allows for interrupted downloads to be resumed, and allows you to quickly clone the repo to multiple places on disk without triggering a download again. The downside, and the reason why I don't list that as the default option, is that the files are then hidden away in a cache folder and it's harder to know where your disk space is being used, and to clear it up if/when you want to remove a download model.
The cache location can be changed with the HF_HOME environment variable, and/or the --cache-dir parameter to huggingface-cli.
For more documentation on downloading with huggingface-cli, please see: HF -> Hub Python Library -> Download files -> Download from the CLI.
To accelerate downloads on fast connections (1Gbit/s or higher), install hf_transfer:
pip3 install hf_transfer
And set environment variable HF_HUB_ENABLE_HF_TRANSFER to 1:
mkdir Synthia-13B-v1.2-GPTQ
HF_HUB_ENABLE_HF_TRANSFER=1 huggingface-cli download TheBloke/Synthia-13B-v1.2-GPTQ --local-dir Synthia-13B-v1.2-GPTQ --local-dir-use-symlinks False
Windows Command Line users: You can set the environment variable by running set HF_HUB_ENABLE_HF_TRANSFER=1 before the download command.
With git (not recommended)
To clone a specific branch with git, use a command like this:
git clone --single-branch --branch gptq-4-32g-actorder_True https://huggingface.co/TheBloke/Synthia-13B-v1.2-GPTQ
Note that using Git with HF repos is strongly discouraged. It will be much slower than using huggingface-hub, and will use twice as much disk space as it has to store the model files twice (it stores every byte both in the intended target folder, and again in the .git folder as a blob.)
How to easily download and use this model in text-generation-webui.

Example Output
You: How does the solar wind affect the gravitational field of Earth? Does it affect the magnetic field?
To understand the effects of the solar wind on the Earth's gravitational and magnetic fields, let's take a closer look at both fields and their relation to the solar wind using
a Tree of Thoughts.
1. **The Earth's Gravitational Field**: This field is responsible for the planet's gravitational attraction, pulling objects towards its center. It is created by the mass of th
e Earth and its distribution within the planet.
2. **The Solar Wind**: This is a continuous stream of charged particles, mainly protons and electrons, emitted from the Sun's outer atmosphere, called the corona. It travels th
rough the solar system at high speeds.
3. **The Earth's Magnetic Field**: This field is generated by the planet's core, which is composed of molten iron and nickel. It protects the Earth from the solar wind and othe
r cosmic radiation, but it is not strong enough to prevent all particles from reaching the Earth's surface.
4. **The Interaction between the Solar Wind and the Earth's Gravitational Field**: The solar wind cannot influence the Earth's gravitational field because the gravitational for
ce is determined by the mass and distribution of matter within the planet, and the solar wind does not affect these factors.
5. **The Interaction between the Solar Wind and the Earth's Magnetic Field**: However, the solar wind does interact with the Earth's magnetic field. The magnetic field acts lik
e a shield, repelling or deflecting the charged particles in the solar wind. This action creates a bow shock, a region where the solar wind slows down as it encounters the Eart
h's magnetic field.
6. **Conclusion**: In conclusion, the solar wind does not affect the Earth's gravitational field, but it does influence the planet's magnetic field, through the creation of a b
ow shock. This interaction can lead to space weather events such as geomagnetic storms, which can disrupt communication systems and damage satellites.
You: Interesting! Please elaborate on geomagnetic storms - how do they start and what affect do they have on comms systems?
Sure! Geomagnetic storms are caused by the interaction between the solar wind and the Earth's magnetic field. They can start when the solar wind carries a particularly strong f
lux of charged particles, which can cause the Earth's magnetic field to compress and rebound. This compression and rebounding process can create geomagnetic storms, which can l
ast for several hours or days.
1. **Effects of Geomagnetic Storms on Communication Systems**: Geomagnetic storms can cause a variety of effects on communication systems, including disruption to GPS signals,
interference with radio communications, and power grid failures. This is because the solar wind particles can interact with the Earth's atmosphere and create electromagnetic cu
rrents that can induce currents in power lines and damage electronic equipment.
2. **Preventative Measures**: To mitigate the effects of geomagnetic storms, technology companies and governments have developed systems to monitor the solar wind and provide e
arly warnings of incoming storms. This information can be used to take preventative measures, such as reducing power consumption or rerouting communications through alternative
routes.
In addition, researchers are exploring ways to improve the Earth's magnetic field, such as creating artificial magnetic shields or modifying the composition of the planet's cor
e. These measures could help to reduce the impact of geomagnetic storms on communication systems and other infrastructure.
In conclusion, geomagnetic storms are a natural phenomenon that can have significant impacts on communication systems and other infrastructure. By monitoring the solar wind and
developing preventative measures, we can help to minimize the disruptions caused by these storms and ensure the continued operation of critical systems.
You: Thanks for that! Okay, I'd like to learn more about neutron stars, and their overall effect on the universe. What is the closest neutron star to us? Elaborate.
Certainly! Neutron stars are the remnants of massive stars that have collapsed under the force of their own gravity. They are incredibly dense, with the mass of the sun squeeze
d into an object with a diameter of about 20 kilometers.
1. **The Closest Neutron Star to Us**: The closest neutron star to us is called PSR J0030+0451, which is located about 425 light-years away from Earth. It is a pulsar, which me
ans that it emits a beam of electromagnetic radiation that sweeps across the sky like a lighthouse.
2. **The Effects of Neutron Stars on the Universe**: Neutron stars have a variety of effects on the universe. They are important stars for understanding the evolution of stars
and the universe as a whole. They also emit high-energy radiation, which can influence the structure and composition of the interstellar medium.
In addition, neutron stars are a source of gravitational waves, which are ripples in the fabric of space-time. These waves are generated when two neutron stars collide, and the
y can provide valuable information about the nature of these objects and the universe as a whole.
3. **Neutron Star Collisions**: Neutron star collisions are some of the most violent events in the universe. When two neutron stars spiral towards each other and collide, they
can produce a variety of exotic phenomena, including gamma-ray bursts, gravitational waves, and even new elements. These collisions can also provide valuable information about
the evolution of stars and the universe as a whole.
In conclusion, neutron stars are incredibly dense and fascinating objects that have a variety of effects on the universe. They are important for understanding the evolution of
stars and the universe as a whole, and they can provide valuable information about the nature of these objects and the universe as a whole.
You: Okay, can you tell me about Wormholes?
Sure! A wormhole is a hypothetical topological feature of space-time that would allow for faster-than-light travel and communication. It is essentially a shortcut through space
-time that connects two distant regions of the universe.
1. **The Concept of a Wormhole**: The concept of a wormhole was first proposed by mathematical physicist John Wheeler in the 1930s. He imagined a tunnel connecting two distant
regions of space-time that allowed for faster-than-light travel.
2. **Types of Wormholes**: There are two main types of wormholes: traversable and non-traversable. A traversable wormhole would allow for faster-than-light travel, while a non-
traversable wormhole would not.
3. **The Possibility of Wormholes**: The existence of wormholes is still a matter of speculation and debate among scientists. Some theories suggest that wormholes could exist a
s a result of the evolution of black holes or the existence of exotic matter with negative energy density.
4. **Potential Applications**: If wormholes could be created and stabilized, they could have a variety of potential applications, including faster-than-light travel and communi
cation, which could revolutionize our understanding of the universe and our ability to explore it.
5. **Challenges to Wormhole Creation**: However, creating and stabilizing a wormhole would require a significant amount of energy and would likely require the manipulation of e
xotic matter with negative energy density. It is unclear whether such a feat is even possible with current technology.
In conclusion, wormholes are a fascinating concept that could have significant implications for our understanding of the universe and our ability to explore it. While their exi
stence is still a matter of speculation and debate, ongoing research and exploration may one day shed light on the possibility of creating and stabilizing a wormhole for practi
cal applications.
Follow-on: What are the challenges to creating and stabilizing a wormhole?
You: Elaborate on "exotic matter with negative energy density"
Sure! Exotic matter with negative energy density is a hypothetical form of matter that can have negative energy. This means that it would have a gravitational attraction that i
s stronger than the repulsive force of positive energy matter, which could allow for the creation of wormholes.
1. **Theoretical Explanation**: The concept of exotic matter with negative energy density is based on theoretical models of the universe that suggest that negative energy densi
ty could exist in the form of a hypothetical particle called a tachyon. Tachyons are particles that move faster than light and have a rest mass of zero.
2. **Potential Applications**: If exotic matter with negative energy density could be created and stabilized, it could have a variety of potential applications, including the c
reation of wormholes and the manipulation of gravity itself. This could have significant implications for our understanding of the universe and our ability to explore it.
3. **Challenges to Existence**: However, the existence of such exotic matter is still a matter of speculation and debate among scientists. There is no direct evidence of its ex
istence, and there are significant challenges to creating and stabilizing such matter.
4. **Search for Exotic Matter**: Despite these challenges, scientists are actively searching for evidence of exotic matter with negative energy density, including through exper
iments that aim to create and detect such particles.
In conclusion, exotic matter with negative energy density is a fascinating concept that could have significant implications for our understanding of the universe and our abilit
y to manipulate it. While its existence is still a matter of speculation and debate, ongoing research and exploration may one day shed light on the possibility of creating and
stabilizing such matter for practical applications.
Follow-on: What are some of the challenges to creating and stabilizing exotic matter with negative energy density?
You: Can you provide the physics equations for "exotic matter with negative energy density"?
Sure, but I'm afraid I won't be able to provide the exact physics equations for exotic matter with negative energy density, as it is still a matter of speculation and debate am
ong scientists. However, I can provide some general principles related to the concept.
It is important to note that negative energy density is a theoretical concept, and there is no direct evidence of its existence. However, some theories suggest that negative en
ergy density could exist in the form of a hypothetical particle called a tachyon. Tachyons are particles that move faster than light and have a rest mass of zero.
The concept of tachyons is based on the theory of special relativity, which states that the speed of light is the universal speed limit for all particles. According to this the
ory, particles with a mass greater than zero cannot travel faster than the speed of light. However, the concept of tachyons introduces particles that have a mass of zero or les
s, which could allow them to travel faster than the speed of light.
The concept of exotic matter with negative energy density is related to the idea of negative energy density, which suggests that particles could have a negative energy density,
meaning they would have a gravitational attraction that is stronger than the repulsive force of positive energy matter. This could have significant implications for our unders
tanding of the universe and our ability to manipulate it.
In conclusion, while the exact physics equations for exotic matter with negative energy density are still a matter of speculation and debate, the concept is based on the princi
ples of special relativity and the possibility of particles moving faster than the speed of light. Future research and exploration may help to shed light on the possibility of
creating and stabilizing such matter for practical applications.
Follow-on: What are some of the practical applications of exotic matter with negative energy density if it could be created and stabilized?
You: What are some of the practical applications of exotic matter with negative energy density if it could be created and stabilized?
If exotic matter with negative energy density could be created and stabilized, it could have a variety of potential practical applications. Here are a few examples:
1. Wormholes: One of the most fascinating potential applications of exotic matter with negative energy density is the creation of wormholes, which could allow for faster-than-l
ight travel and communication. If wormholes were stable and could be created on demand, they could revolutionize our understanding of the universe and our ability to explore it
.
2. Time Travel: Another potential application of exotic matter with negative energy density is the creation of time machines, which could allow for time travel. While the conce
pt of time travel is still a matter of speculation and debate, the idea of negative energy density could potentially be used to create a device that could manipulate the fabric
of space-time and allow for travel back in time.
3. Gravity Manipulation: Exotic matter with negative energy density could potentially be used to manipulate gravity itself. By creating a negative energy density in a given reg
ion of space-time, it may be possible to create a gravitational field that is stronger or weaker than the surrounding region. This could have significant implications for our a
bility to manipulate objects and structures in space, as well as our understanding of the nature of gravity itself.
4. Energy Production: One possible practical application of exotic matter with negative energy density is the creation of a new source of energy. If such matter could be create
d and controlled, it could be used to generate large amounts of energy in a variety of applications, including power generation, transportation, and space exploration.
In conclusion, exotic matter with negative energy density could have a wide range of potential practical applications if it could be created and stabilized. While the concept i
s still a matter of speculation and debate, ongoing research and exploration may one day shed light on the possibility of creating and manipulating such matter for practical ap
plications.
