## MODEL_ID
|

```shell

--model-id <MODEL_ID>
|
||||
The name of the model to load. Can be a MODEL_ID as listed on <https://hf.co/models> like `gpt2` or `OpenAssistant/oasst-sft-1-pythia-12b`. Or it can be a local directory containing the necessary files as saved by `save_pretrained(...)` methods of transformers

## REVISION

## SHARDED
|

```shell

--sharded <SHARDED>
|
||||
Whether to shard the model across multiple GPUs By default text-generation-inference will use all available GPUs to run the model. Setting it to `false` deactivates `num_shard`

|
||||
```shell
|
||||
--num-shard <NUM_SHARD>
|
||||
The number of shards to use if you don't want to use all GPUs on a given machine. You can use `CUDA_VISIBLE_DEVICES=0,1 text-generation-launcher... --num_shard 2` and `CUDA_VISIBLE_DEVICES=2,3 text-generation-launcher... --num_shard 2` to launch 2 copies with 2 shard each on a given machine with 4 GPUs for instance

- bitsandbytes-nf4: Bitsandbytes 4bit. Can be applied on any model, will cut the memory requirement by 4x, but it is known that the model will be much slower to run than the native f16

- bitsandbytes-fp4: Bitsandbytes 4bit. nf4 should be preferred in most cases but maybe this one has better perplexity performance for you model

## DTYPE
|
||||
```shell
|

--dtype <DTYPE>
|

The dtype to be forced upon the model. This option cannot be used with `--quantize`

## TRUST_REMOTE_CODE
|
||||
```shell
|
||||
--trust-remote-code
|
||||
Whether you want to execute hub modelling code. Explicitly passing a `revision` is encouraged when loading a model with custom code to ensure no malicious code has been contributed in a newer revision
|
||||
|
||||
[env: TRUST_REMOTE_CODE=]
|
||||
|
||||
```
|
||||
## MAX_CONCURRENT_REQUESTS
|
||||
```shell
|
||||
--max-concurrent-requests <MAX_CONCURRENT_REQUESTS>
|
||||
The maximum amount of concurrent requests for this particular deployment. Having a low limit will refuse clients requests instead of having them wait for too long and is usually good to handle backpressure correctly
|
||||
|
||||
[env: MAX_CONCURRENT_REQUESTS=]
|
||||
[default: 128]
|
||||
|
||||
```
|
||||
## MAX_BEST_OF
|
||||
```shell
|
||||
--max-best-of <MAX_BEST_OF>
|
||||
This is the maximum allowed value for clients to set `best_of`. Best of makes `n` generations at the same time, and return the best in terms of overall log probability over the entire generated sequence
|
||||
|
||||
[env: MAX_BEST_OF=]
|
||||
[default: 2]
|
||||
|
||||
```
|
||||
## MAX_STOP_SEQUENCES
|
||||
```shell
|
||||
--max-stop-sequences <MAX_STOP_SEQUENCES>
|
||||
This is the maximum allowed value for clients to set `stop_sequences`. Stop sequences are used to allow the model to stop on more than just the EOS token, and enable more complex "prompting" where users can preprompt the model in a specific way and define their "own" stop token aligned with their prompt
|
||||
|
||||
[env: MAX_STOP_SEQUENCES=]
|
||||
[default: 4]
|
||||
|
||||
```
|
||||
## MAX_TOP_N_TOKENS
|
||||
```shell
|
||||
--max-top-n-tokens <MAX_TOP_N_TOKENS>
|
||||
This is the maximum allowed value for clients to set `top_n_tokens`. `top_n_tokens is used to return information about the the `n` most likely tokens at each generation step, instead of just the sampled token. This information can be used for downstream tasks like for classification or ranking
|
||||
|
||||
[env: MAX_TOP_N_TOKENS=]
|
||||
[default: 5]
|
||||
|
||||
```
|
||||
## MAX_INPUT_LENGTH
|
||||
```shell
|
||||
--max-input-length <MAX_INPUT_LENGTH>
|
||||
This is the maximum allowed input length (expressed in number of tokens) for users. The larger this value, the longer prompt users can send which can impact the overall memory required to handle the load. Please note that some models have a finite range of sequence they can handle
|
||||
|
||||
[env: MAX_INPUT_LENGTH=]
|
||||
[default: 1024]
|
||||
|
||||
```
|
||||
## MAX_TOTAL_TOKENS
|
||||
```shell
|
||||
--max-total-tokens <MAX_TOTAL_TOKENS>
|
||||
This is the most important value to set as it defines the "memory budget" of running clients requests. Clients will send input sequences and ask to generate `max_new_tokens` on top. with a value of `1512` users can send either a prompt of `1000` and ask for `512` new tokens, or send a prompt of `1` and ask for `1511` max_new_tokens. The larger this value, the larger amount each request will be in your RAM and the less effective batching can be
|
||||
|
||||
[env: MAX_TOTAL_TOKENS=]
|
||||
[default: 2048]
|
||||
|
||||
```
|
||||
## WAITING_SERVED_RATIO
|
||||
```shell
|
||||
--waiting-served-ratio <WAITING_SERVED_RATIO>
|
||||
This represents the ratio of waiting queries vs running queries where you want to start considering pausing the running queries to include the waiting ones into the same batch. `waiting_served_ratio=1.2` Means when 12 queries are waiting and there's only 10 queries left in the current batch we check if we can fit those 12 waiting queries into the batching strategy, and if yes, then batching happens delaying the 10 running queries by a `prefill` run.

## MAX_BATCH_PREFILL_TOKENS
|
||||
```shell
|
||||
--max-batch-prefill-tokens <MAX_BATCH_PREFILL_TOKENS>
|
||||
Limits the number of tokens for the prefill operation. Since this operation take the most memory and is compute bound, it is interesting to limit the number of requests that can be sent

## MAX_WAITING_TOKENS
|

```shell

--max-waiting-tokens <MAX_WAITING_TOKENS>
|
||||
This setting defines how many tokens can be passed before forcing the waiting queries to be put on the batch (if the size of the batch allows for it). New queries require 1 `prefill` forward, which is different from `decode` and therefore you need to pause the running batch in order to run `prefill` to create the correct values for the waiting queries to be able to join the batch.
