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 dataset used for quantisation. Using a dataset more appropriate to the model's training can improve quantisation accuracy. Note that the GPTQ 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.

Example Output

You: How is a rocket launched from the surface of the earth to Low Earth Orbit? 

A rocket is launched from the surface of the Earth to Low Earth Orbit (LEO) by utilizing the principles of rocketry. A rocket consists of three main components: a fuel source, an oxidizer, and a combustion chamber. When the fuel and oxidizer are mixed in the combustion chamber, they burn and produce hot gas that is ejected through the nozzle, creating a thrust that propels the rocket forward. 

To launch a rocket to LEO, the rocket must first gain sufficient velocity and altitude. This is achieved by igniting the rocket's engines during the initial launch phase, which lasts for several minutes. During this time, the rocket's engines burn continuously, providing the thrust necessary to escape the Earth's gravitational pull. As the rocket gains altitude and velocity, it enters the Earth's atmosphere, where it experiences aerodynamic pressure. 

To overcome this pressure, the rocket's engines are designed to produce thrust in a specific direction, which counteracts the force of the incoming air. This is known as aerodynamic control. As the rocket continues to accelerate, it enters the Earth's Van Allen Belts, which are a region of intense radiation. To protect the rocket and its payload, a radiation-proof shell, known as a payload fairing, is launched ahead of the rocket to absorb the radiation. 

Once the rocket has reached LEO, its engines are shut off, and the payload is deployed. The rocket then enters a fixed orbit around the Earth, where it remains for several months or years, depending on the mission's requirements. 

Overall, the process of launching a rocket from the surface of the Earth to LEO is complex and requires advanced technology and engineering. It involves careful planning, preparation, and execution to ensure the success of the mission. 

You: What's the velocity required?

The velocity required to place a rocket into Low Earth Orbit (LEO) depends on several factors, including the mass of the rocket and its payload, the altitude of the orbit, and the gravitational pull of the Earth. Generally, a rocket must reach a speed of around 7.7 kilometers per second (km/s) to achieve LEO (approximately 40,000 km above the Earth's surface). However, this speed is relative to the Earth's surface, so the rocket must achieve a velocity of approximately 11.3 km/s relative to the Earth's center of mass. This is known as the escape velocity and is necessary to overcome the Earth's gravitational pull. 

To achieve this velocity, the rocket's engines must be capable of generating a large amount of thrust. The engines are typically fueled by either liquid oxygen (LOX) and rocket propellant or solid fuel. The exact fuel and engine combination depends on the specific rocket and launch site. 

Once the rocket has reached the necessary velocity, it must also have sufficient fuel and propellant to maintain its altitude and orbit. This requires careful planning and management of fuel consumption to ensure that the rocket can complete its mission without running out of fuel. 

Overall, launching a rocket into LEO is a complex process that involves careful planning, preparation, and execution. Achieving the necessary velocity and maintaining the rocket's orbit requires a high level of technical expertise and precision.
