Predibase | liteLLM (original) (raw)

LiteLLM supports all models on Predibase

Usage​

API KEYS​

import os 
os.environ["PREDIBASE_API_KEY"] = ""

Example Call​

from litellm import completion
import os
## set ENV variables
os.environ["PREDIBASE_API_KEY"] = "predibase key"
os.environ["PREDIBASE_TENANT_ID"] = "predibase tenant id"

# predibase llama-3 call
response = completion(
    model="predibase/llama-3-8b-instruct", 
    messages = [{ "content": "Hello, how are you?","role": "user"}]
)

Advanced Usage - Prompt Formatting​

LiteLLM has prompt template mappings for all meta-llama llama3 instruct models. See Code

To apply a custom prompt template:

import litellm

import os 
os.environ["PREDIBASE_API_KEY"] = ""

# Create your own custom prompt template 
litellm.register_prompt_template(
        model="togethercomputer/LLaMA-2-7B-32K",
        initial_prompt_value="You are a good assistant" # [OPTIONAL]
        roles={
            "system": {
                "pre_message": "[INST] <<SYS>>\n", # [OPTIONAL]
                "post_message": "\n<</SYS>>\n [/INST]\n" # [OPTIONAL]
            },
            "user": { 
                "pre_message": "[INST] ", # [OPTIONAL]
                "post_message": " [/INST]" # [OPTIONAL]
            }, 
            "assistant": {
                "pre_message": "\n" # [OPTIONAL]
                "post_message": "\n" # [OPTIONAL]
            }
        }
        final_prompt_value="Now answer as best you can:" # [OPTIONAL]
)

def predibase_custom_model():
    model = "predibase/togethercomputer/LLaMA-2-7B-32K"
    response = completion(model=model, messages=messages)
    print(response['choices'][0]['message']['content'])
    return response

predibase_custom_model()

Passing additional params - max_tokens, temperature​

See all litellm.completion supported params here

# !uv add litellm
from litellm import completion
import os
## set ENV variables
os.environ["PREDIBASE_API_KEY"] = "predibase key"

# predibae llama-3 call
response = completion(
    model="predibase/llama3-8b-instruct", 
    messages = [{ "content": "Hello, how are you?","role": "user"}],
    max_tokens=20,
    temperature=0.5
)

proxy

  model_list:
    - model_name: llama-3
      litellm_params:
        model: predibase/llama-3-8b-instruct
        api_key: os.environ/PREDIBASE_API_KEY
        max_tokens: 20
        temperature: 0.5

Passings Predibase specific params - adapter_id, adapter_source,​

Send params not supported by litellm.completion() but supported by Predibase by passing them to litellm.completion

Example adapter_id, adapter_source are Predibase specific param - See List

# !uv add litellm
from litellm import completion
import os
## set ENV variables
os.environ["PREDIBASE_API_KEY"] = "predibase key"

# predibase llama3 call
response = completion(
    model="predibase/llama-3-8b-instruct", 
    messages = [{ "content": "Hello, how are you?","role": "user"}],
    adapter_id="my_repo/3",
    adapter_source="pbase",
)
