Predibase is a platform for fine-tuning and serving open-source Large Language Models (LLMs). It's built on top of open-source [LoRAX](https://loraexchange.ai/). ## Account Setup [Comet](https://www.comet.com/site) provides a hosted version of the Opik platform, [simply create an account](https://www.comet.com/signup) and grab your API Key. > You can also run the Opik platform locally, see the [installation guide](/guides/overview-self-host-overview) for more information. ## Tracking your LLM calls Predibase can be used to serve open-source LLMs and is available as a model provider in LangChain. We will leverage the Opik integration with LangChain to track the LLM calls made using Predibase models. ## Getting Started ### Installation To use the Opik integration with Predibase, you'll need to have both the `opik`, `predibase` and `langchain` packages installed. You can install them using pip: ```bash pip install opik predibase langchain ``` ### Configuring Opik Configure the Opik Python SDK for your deployment type. See the [Python SDK Configuration guide](https://www.comet.com/tracing/advanced/sdk_configuration) for detailed instructions on: - **CLI configuration**: `opik configure` - **Code configuration**: `opik.configure()` - **Self-hosted vs Cloud vs Enterprise** setup - **Configuration files** and environment variables ### Configuring Predibase You will also need to set the `PREDIBASE_API_TOKEN` environment variable to your Predibase API token. You can set it as an environment variable: ```bash export PREDIBASE_API_TOKEN= ``` Or set it programmatically: ```python import os import getpass if "PREDIBASE_API_TOKEN" not in os.environ: os.environ["PREDIBASE_API_TOKEN"] = getpass.getpass("Enter your Predibase API token: ") ``` ## Logging LLM calls In order to log the LLM calls to Opik, you will need to wrap the Predibase model with the `OpikTracer` from the LangChain integration. When making calls with that wrapped model, all calls will be logged to Opik: ```python import os from langchain_community.llms import Predibase from opik.integrations.langchain import OpikTracer os.environ["OPIK_PROJECT_NAME"] = "predibase-integration-demo" # Create the Opik tracer opik_tracer = OpikTracer(tags=["predibase", "langchain"]) # Create Predibase model model = Predibase( model="mistral-7b", predibase_api_key=os.environ.get("PREDIBASE_API_TOKEN"), ) # Test the model with Opik tracing response = model.invoke( "Can you recommend me a nice dry wine?", config={ "temperature": 0.5, "max_new_tokens": 1024, "callbacks": [opik_tracer] } ) print(response) ``` In addition to passing the OpikTracer to the invoke method, you can also define it during the creation of the `Predibase` object: ```python model = Predibase( model="mistral-7b", predibase_api_key=os.environ.get("PREDIBASE_API_TOKEN"), ).with_config({"callbacks": [opik_tracer]}) ``` :::callout{intent="tip"} You can learn more about the Opik integration with LangChain in our [LangChain integration guide](/guides/python-langchain). ::: The trace will now be available in the Opik UI for further analysis. :::frame ::: ## Advanced Usage ### SequentialChain Example Now, let's create a more complex chain and run it with Opik tracing: ```python from langchain.chains import LLMChain, SimpleSequentialChain from langchain_core.prompts import PromptTemplate # Synopsis chain template = """You are a playwright. Given the title of play, it is your job to write a synopsis for that title. Title: {title} Playwright: This is a synopsis for the above play:""" prompt_template = PromptTemplate(input_variables=["title"], template=template) synopsis_chain = LLMChain(llm=model, prompt=prompt_template) # Review chain template = """You are a play critic from the New York Times. Given the synopsis of play, it is your job to write a review for that play. Play Synopsis: {synopsis} Review from a New York Times play critic of the above play:""" prompt_template = PromptTemplate(input_variables=["synopsis"], template=template) review_chain = LLMChain(llm=model, prompt=prompt_template) # Overall chain overall_chain = SimpleSequentialChain( chains=[synopsis_chain, review_chain], verbose=True ) # Run the chain with Opik tracing review = overall_chain.run("Tragedy at sunset on the beach", callbacks=[opik_tracer]) print(review) ``` ### Accessing Logged Traces We can access the trace IDs collected by the Opik tracer: ```python traces = opik_tracer.created_traces() print("Collected trace IDs:", [trace.id for trace in traces]) # Flush traces to ensure all data is logged opik_tracer.flush() ``` ### Fine-tuned LLM Example Finally, let's use a fine-tuned model with Opik tracing: **Note:** In order to use a fine-tuned model, you will need to have access to the model and the correct model ID. The code below will return a `NotFoundError` unless the `model` and `adapter_id` are updated. ```python fine_tuned_model = Predibase( model="my-base-LLM", predibase_api_key=os.environ.get("PREDIBASE_API_TOKEN"), predibase_sdk_version=None, adapter_id="my-finetuned-adapter-id", adapter_version=1, **{ "api_token": os.environ.get("HUGGING_FACE_HUB_TOKEN"), "max_new_tokens": 5, }, ) # Configure the Opik tracer fine_tuned_model = fine_tuned_model.with_config({"callbacks": [opik_tracer]}) # Invoke the fine-tuned model response = fine_tuned_model.invoke( "Can you help categorize the following emails into positive, negative, and neutral?", **{"temperature": 0.5, "max_new_tokens": 1024}, ) print(response) # Final flush to ensure all traces are logged opik_tracer.flush() ``` ## Tracking your fine-tuning training runs If you are using Predibase to fine-tune an LLM, we recommend using Predibase's integration with Comet's Experiment Management functionality. You can learn more about how to set this up in the [Comet integration guide](https://docs.predibase.com/integrations/comet) in the Predibase documentation. If you are already using an Experiment Tracking platform, worth checking if it has an integration with Predibase. ## Related pages - [Observability for Anthropic with Opik](./python-anthropic.md) - [Observability for AWS Bedrock with Opik](./python-bedrock.md) - [Observability for BytePlus with Opik](./python-byteplus.md) - [Observability for Cohere with Opik](./python-cohere.md) - [Observability for DeepSeek with Opik](./python-deepseek.md) - [Observability for Fireworks AI with Opik](./python-fireworks-ai.md) - [Observability for Google Gemini (Python) with Opik](./python-gemini.md) - [Observability for Groq with Opik](./python-groq.md) - [Observability for TypeSafe AI (Python) with Opik](./python-typesafe.md) - [Observability for MiniMax with Opik](./python-minimax.md) # Agent Instructions Cite this page’s canonical URL and keep its documentation version.
