Usage

API KEYS

os.environ["BYTEZ_API_KEY"] = "YOUR_BYTEZ_KEY_GOES_HERE"

Example Call

from litellm import completion

## set ENV variables
os.environ["BYTEZ_API_KEY"] = "YOUR_BYTEZ_KEY_GOES_HERE"

response = completion(
    model="bytez/google/gemma-3-4b-it",
    messages = [{ "content": "Hello, how are you?","role": "user"}]
)

1. Add models to your config.yaml

model_list:
  - model_name: gemma-3
    litellm_params:
      model: bytez/google/gemma-3-4b-it
      api_key: os.environ/BYTEZ_API_KEY

2. Start the proxy

$ BYTEZ_API_KEY=YOUR_BYTEZ_API_KEY_HERE litellm --config /path/to/config.yaml --debug

3. Send Request to LiteLLM Proxy Server

client = openai.OpenAI(
    api_key="sk-1234",             # pass litellm proxy key, if you're using virtual keys
    base_url="http://0.0.0.0:4000" # litellm-proxy-base url
)

response = client.chat.completions.create(
    model="gemma-3",
    messages = [
      {
          "role": "system",
          "content": "Be a good human!"
      },
      {
          "role": "user",
          "content": "What do you know about earth?"
      }
  ]
)

print(response)

curl --location 'http://0.0.0.0:4000/chat/completions' \\
    --header 'Authorization: Bearer sk-1234' \\
    --header 'Content-Type: application/json' \\
    --data '{
    "model": "gemma-3",
    "messages": [
      {
          "role": "system",
          "content": "Be a good human!"
      },
      {
          "role": "user",
          "content": "What do you know about earth?"
      }
      ],
}'

Automatic Prompt Template Handling

All prompt formatting is handled automatically by our API when you send a messages list to it!

If you wish to use custom formatting, please let us know via either help@bytez.com or on our Discord and we will work to provide it!

Passing additional params - max_tokens, temperature

See all litellm.completion supported params here

# !uv add litellm
from litellm import completion

## set ENV variables
os.environ["BYTEZ_API_KEY"] = "YOUR_BYTEZ_KEY_HERE"

# bytez gemma-3 call
response = completion(
    model="bytez/google/gemma-3-4b-it",
    messages = [{ "content": "Hello, how are you?","role": "user"}],
    max_tokens=20,
    temperature=0.5
)

proxy

model_list:
  - model_name: gemma-3
    litellm_params:
      model: bytez/google/gemma-3-4b-it
      api_key: os.environ/BYTEZ_API_KEY
      max_tokens: 20
      temperature: 0.5

Passing Bytez-specific params

Any kwarg supported by huggingface we also support! (Provided the model supports it.)

Example repetition_penalty

# !uv add litellm
from litellm import completion

## set ENV variables
os.environ["BYTEZ_API_KEY"] = "YOUR_BYTEZ_KEY_HERE"

# bytez llama3 call with additional params
response = completion(
    model="bytez/google/gemma-3-4b-it",
    messages = [{ "content": "Hello, how are you?","role": "user"}],
    repetition_penalty=1.2,
)
