The agent runtime for builders who ship.

Build, run, and deploy reliable AI agents at enterprise scale — multi-LLM routing, persistent memory, MCP-native tools, durable workflows, and full observability, out of the box.

Continuum is a production-grade Python framework for building, orchestrating, and shipping autonomous AI agents at enterprise scale. It unifies a clean, typed agent core with cost-aware multi-model inference, stateful long- and short-term memory, open standards-based tool calling, durable execution, and end-to-end observability — all behind one small, composable, type-safe API.

• 🤖 Agentic core & orchestration — a strongly-typed agent primitive with full lifecycle hooks, schema-validated structured outputs, and nine composable multi-agent patterns (sequential, parallel, loop, routing, planning, reflection, debate, scatter, supervised).
• 🔀 Smart Inference — cost-aware inference routing that classifies every request by complexity and dispatches it to the cheapest capable model, with seamless cross-provider failover and zero lock-in.
• 🧠 Stateful memory — persistent semantic long-term recall plus low-latency working memory, with multi-tenant isolation scopes and built-in PII redaction for privacy-by-default agents.
• 🔌 Open tool calling — plug into any standards-based tool ecosystem (Model Context Protocol) across multiple transports, with fine-grained capability scoping, context capture/injection, and rich generative-UI artifacts.
• 🔁 Durable execution — long-running, crash- and restart-safe agent workflows with human-in-the-loop approval gates and exactly-once guarantees.
• 🔭 Full observability — first-class distributed tracing, token/latency/error telemetry, and one-line function instrumentation for complete run transparency.
• 🌐 Model-agnostic — target frontier or open-weight models through a single model string; swap providers without touching agent code.
• 🤝 Multi-agent handoffs — context-preserving agent-to-agent delegation with history summarization, cycle detection, and depth control.
• 📡 Real-time streaming — token-, tool-, handoff-, and memory-level events streamed the moment they happen.
• ✅ Built-in evaluation — turn live production traces into golden datasets and regression-test agent quality with standard LLM-evaluation metrics.

Requirements: Python 3.13+ and Docker (for Redis · Qdrant/Milvus · Langfuse).

python3.13 -m venv .venv && source .venv/bin/activate
pip install shyftlabs-continuum

continuum up                 # start local infra (Redis + Qdrant); writes ./.env
echo "OPENAI_API_KEY=sk-…" >> .env   # add your provider key(s) — see Configuration below

continuum up ships with the package — it locates the bundled Docker stack and starts it for you, so there's no compose file to find or copy. It defaults to the minimal profile (Redis + Qdrant); pick a bigger one with continuum up standard / continuum up full.

Contributors working from a clone: git clone https://github.com/shyftlabs/continuum.git && cd continuum, then python3.13 -m venv .venv && source .venv/bin/activate, pip install -e ".[dev]", cp .env.template .env, and continuum up.

Each profile also writes a managed block to ./.env (VECTOR_STORE_PROVIDER, LANGFUSE_ENABLED, …) so the SDK only talks to services that are actually running. Other commands: continuum down [-v], continuum status, continuum logs [service] [-f], continuum config-path.

Port conflicts? Every published host port is overridable via .env (defaults shown): SESSION_REDIS_PORT=6380, QDRANT_PORT=6333, QDRANT_GRPC_PORT=6334, MILVUS_PORT=19530, LANGFUSE_WEB_PORT=3000, LANGFUSE_WORKER_PORT=3030, LANGFUSE_POSTGRES_PORT=5433, LANGFUSE_REDIS_PORT=6382, CLICKHOUSE_HTTP_PORT=8123, CLICKHOUSE_NATIVE_PORT=9000, MINIO_API_PORT=9090, MINIO_CONSOLE_PORT=9091, TEMPORAL_PORT=7233, TEMPORAL_UI_PORT=8233, TEMPORAL_POSTGRES_PORT=5434. For the stores the SDK connects to (QDRANT_PORT, MILVUS_PORT, SESSION_REDIS_PORT), the same variable drives both the container and the client, so they stay in sync.

Your first agent:

import asyncio
from continuum.agent import BaseAgent, AgentRunner

async def main():
    agent = BaseAgent(
        name="hello-agent",
        instructions="You are a friendly assistant.",
        model="gpt-4o-mini",
    )
    runner = AgentRunner()
    response = await runner.run(agent, "Hi!")
    print(response.content)

asyncio.run(main())

AgentRunner.run() returns an AgentResponse with content, structured_output, usage, tool_calls, run_artifacts, latency_ms, and the full handoff chain. See the docs for streaming, tools/MCP, memory, handoffs, and workflows.

Continuum is configured through environment variables (copy .env.template → .env). Set keys only for the providers and components you use — everything else has sensible defaults. The most common settings:

Optional extras: pip install -e ".[temporal]" for Temporal, ".[eval]" for evaluation, ".[embeddings]" for local embeddings. See .env.template for the complete, annotated reference.

Full documentation lives at docs.continuum.shyftlabs.io — guides for building & running agents, Smart Inference, memory, tools/MCP, workflows, handoffs, streaming, evaluation, and the research behind it.

Markdown sources are also in docs/ if you prefer reading on GitHub — e.g. agent.md, memory.md, tools.md, and the integration GUIDE.md.

Runnable demos live under playground/:

• gateway-local-shop — an MCP server + agent + chat UI for a pet-shop assistant (end-to-end: server → agent → UI).
• gateway-multi-agent-shop — a multi-agent workflow variant with routing and handoffs.
• frontend/ — the demo web UIs (assortment, commerce-chat).
