lexigram-ai-llm

LLM client layer for the Lexigram Framework — OpenAI, Anthropic, Ollama, Cohere, Groq, Mistral

Overview

LLM client layer for the Lexigram Framework. Provides typed, async-first clients for 15 providers, multi-provider routing, thinking/reasoning control, structured extraction, streaming, embeddings, and model management — all wired through the DI container via LLMModule. configure() with no arguments uses the defaults but boots the client eagerly, so the provider's API key (e.g. OPENAI_API_KEY) must be available; stub() is the test-safe path.

Install

uv add lexigram-ai-llm
# Optional extras
uv add "lexigram-ai-llm[openai,anthropic,ollama]"

Quick Start

from lexigram import Application
from lexigram.di.module import Module, module

from lexigram.ai.llm import LLMModule
from lexigram.ai.llm.config import ClientConfig


@module(
    imports=[
        LLMModule.configure(
            ClientConfig(provider="anthropic", model="claude-sonnet-4-6")
        )
    ]
)
class AppModule(Module):
    pass


async with Application.boot(modules=[AppModule]) as app:
    # use app.container to resolve services
    ...

Configuration

Zero-config usage: LLMModule.configure() with no arguments uses default settings (provider openai, model gpt-4-turbo), but the client is created eagerly at boot — set the provider's API key via config or the provider SDK env var first. For tests, use LLMModule.stub().

Option 1 — YAML file

# application.yaml
ai_llm:
  provider: "anthropic"
  model: "claude-sonnet-4-6"
  api_key: "${LEX_AI_LLM__API_KEY}"
  temperature: 0.7
  max_tokens: null

Option 2 — Profiles + Environment Variables (recommended)

export LEX_AI_LLM__PROVIDER=anthropic
# Environment variables for each field

Option 3 — Python

from lexigram.ai.llm.config import ClientConfig
from lexigram.ai.llm import LLMModule

config = ClientConfig(
    provider="anthropic",
    model="claude-sonnet-4-6",
)
LLMModule.configure(config)
