llmfy 0.5.3

`LLMfy` is a framework for developing applications with large language models (LLMs).

LLMfy is a flexible and developer-friendly framework designed to streamline the creation of applications powered by large language models (LLMs). It provides essential tools and abstractions that simplify the integration, orchestration, and management of LLMs across various use cases, enabling developers to focus on building intelligent, context-aware solutions without getting bogged down in low-level model handling. With support for modular components, prompt engineering, and extensibility, LLMfy accelerates the development of AI-driven applications from prototyping to production.

Example

LLMfy Example

from llmfy import (
    OpenAIModel,
    OpenAIConfig,
    LLMfy,
    Message,
    Role,
    LLMfyException,
)

def sample_prompt():
    info = """Irufano adalah seorang software engineer.
    Dia berasal dari Indonesia.
    Kamu bisa mengunjungi websitenya di https:://irufano.github.io"""

    # Configuration
    config = OpenAIConfig(temperature=0.7)
    llm = OpenAIModel(model="gpt-4o-mini", config=config)

    SYSTEM_PROMPT = """Answer any user questions based solely on the data below:
    <data>
    {info}
    </data>
    
    DO NOT response outside context."""

    # Initialize framework
    framework = LLMfy(llm, system_message=SYSTEM_PROMPT, input_variables=["info"])

    try:
        messages = [Message(role=Role.USER, content="apa ibukota china")]
       
        response = framework.invoke(messages, info=info)
        print(f"\n>> {response.result.content}\n")

    except LLMfyException as e:
        print(f"{e}")

Develop as Contributor

Build package

uv build

Trigger build and deploy to PyPI

# TAG_NAME must start with "v" (e.g., v1.0.0)
git tag -a [TAG_NAME] -m "[TAG_MESSAGE]"

# push tag to remote
git push origin [TAG_NAME]

After deploy on local

After the CI moves the tag, your local tag still points to the old commit. To sync:

git fetch --tags --force

The --force flag is needed because git fetch --tags alone won't update tags that already exist locally.

Package Development on local

uv sync --group dev --group docs

or

uv sync --all-groups

Mkdocs run on local

uv sync --group docs

# Serve on local
mkdocs serve

# Build docs
