Agentify

Production-ready AI agent library built on the OpenAI SDK

Build and orchestrate AI agents—from simple assistants to complex multi-agent systems. Agentify targets the OpenAI-compatible Chat Completions interface, enabling seamless switching between providers (OpenAI, Azure, DeepSeek, Gemini, Anthropic, Llama, Local LLMs) without code changes. It also includes experimental native Codex support through ChatGPT OAuth.

Installation

pip install agentify-core

Optional backends:

pip install agentify-core[redis]      # Redis memory store
pip install agentify-core[elastic]    # Elasticsearch store
pip install agentify-core[codex]      # Native Codex provider
pip install agentify-core[all]        # All optional dependencies

Quick Start

The Agent helper gets you running in one call — only model is required, and an in-memory store and conversation address are created automatically:

from agentify import Agent, tool

@tool
def get_time() -> dict:
    """Returns the current time."""
    from datetime import datetime
    return {"time": datetime.now().strftime("%H:%M:%S")}

agent = Agent(
    "You are a helpful assistant.",
    model="gpt-5.5",          # provider defaults to "openai"
    tools=[get_time],
)

print(agent.run("What time is it?"))

# Async usage is also available:
# print(await agent.arun("What time is it?"))

Agent is a thin subclass of BaseAgent; extra keyword arguments (reasoning_effort, model_kwargs, temperature, stream, provider, ...) are forwarded to the config.

Full control with BaseAgent

For custom stores, shared memory services, or multi-tenant routing:

from agentify import BaseAgent, AgentConfig, MemoryService, MemoryAddress, InMemoryStore

memory = MemoryService(store=InMemoryStore())
addr = MemoryAddress(conversation_id="session_1")

agent = BaseAgent(
    config=AgentConfig(
        name="Assistant",
        system_prompt="You are a helpful assistant.",
        provider="openai",
        model_name="gpt-5.5",
        reasoning_effort="high",  # optional: "low", "medium", "high"
        model_kwargs={"max_completion_tokens": 5000},
    ),
    memory=memory,
    memory_address=addr,
    tools=[get_time],
)

print(agent.run("What time is it?"))

Native Codex Provider

Codex support is experimental and uses ChatGPT OAuth through the Codex CLI:

pip install agentify-core[codex]
codex login
codex login status

codex login opens the Codex CLI authentication flow. Choose ChatGPT login when you want to use the Codex models available to your ChatGPT account. If the login is successful, codex login status should report that you are logged in. Model availability and quota depend on your Codex CLI version and ChatGPT account.

Then use the same Agentify API:

agent = BaseAgent(
    config=AgentConfig(
        name="CodexAgent",
        system_prompt="You are a helpful assistant.",
        provider="codex",
        model_name="gpt-5.5",
    ),
    memory=memory,
    memory_address=addr,
    tools=[get_time],
)

response = agent.run("Use the tool and answer concisely.")

Agentify keeps memory as the source of truth and sends the current conversation state to Codex. Normal tools=[...] are exposed to Codex through an internal runtime MCP bridge, so users do not need to manually wrap tools for common use.

Supported Codex features include:

• Agentify-managed memory with SQLite, in-memory, Redis or Elasticsearch stores.
• Native Codex thread memory with client_config_override={"memory_mode": "codex_thread"} — recommended for interactive multi-turn assistants (~1.5–1.7x faster per turn), with optional thread_map_path to persist sessions across restarts. The system prompt is passed as thread-level instructions every turn (instructions_mode: "developer" default, or "base"), so the persona survives context compaction.
• Runtime MCP tools with logs and persisted tool-call history, isolated per session.
• Typed, actionable errors (OAuth/login missing, CLI not found, model unsupported, usage limit) that stop useless retries.
• stream=True using Codex turn events.
• image_path=... multimodal input when supported by the installed Codex SDK.
• Structured output with model_kwargs={"output_schema": ...} or OpenAI-style response_format.

For long-running apps, call agent.close() or await agent.aclose() to release provider resources.

Memory Backends

from agentify.memory.stores import InMemoryStore
from agentify.memory.stores.sqlite_store import SQLiteStore
from agentify.memory.stores.redis_store import RedisStore

# In-memory (default, for development)
store = InMemoryStore()

# SQLite (persistent, zero-config)
store = SQLiteStore(db_path="./agent.db")

# Redis (production, distributed)
store = RedisStore(url="redis://localhost:6379/0")

---

Composable Flows

All primitives share the same run()/arun() interface:

• BaseAgent — Single agent with tools
• Team — Supervisor routes to worker agents
• SequentialPipeline — Output flows step-to-step
• HierarchicalTeam — Tree structures for delegation

Nest freely: Teams of Pipelines, Pipelines of Teams, dynamic routing at runtime.
