Build Python agents your platform team can operate } subtitle="Duale AI gives Python teams a durable runtime for bounded agent work: stable contracts, routing policy, retries, task identifiers, and project-specific review context without tying every project to one provider stack." primaryCta={{ label: "Request Python access", dialog: "contact" }} secondaryCta={{ label: "See pricing", href: "https://duale.ai/en/product/pricing.md" }} />

Use Python to submit bounded agent work, attach routing policy, set deadlines, request typed results, and keep a task identifier for follow-up. Treat models as replaceable capacity. Route by policy inputs such as quality, speed, guardrail preference, and priority instead of hard-coding every call. Task submission, terminal result, timeouts, errors, retries, and routing decisions can become product events where the integration captures them.

```python from datetime import datetime, timedelta, timezone from pydantic import BaseModel from duale import DualeConfig, DualeSDK, RoutingPolicy, ask class SupportDecision(BaseModel): next_action: str reason: str risk: str async def main() -> None: deadline = datetime.now(timezone.utc) + timedelta(minutes=30) async with DualeSDK(config=DualeConfig(), auto_start=False) as sdk: response = await ask( action="Review this support case and return the next safe action.", res=SupportDecision, routing=RoutingPolicy( target_accuracy=0.8, target_guardrails=0.7, speed_preference=0.4, ), deadline=deadline, sdk=sdk, ) decision = await response.model() print(response.task_id, decision.next_action) asyncio.run(main()) ```

Agent work can fail, run long, or need a safer route. The runtime keeps those behaviors explicit instead of hiding them in application glue. Define the work boundary once. Models, provider policy, retention, and governance requirements can change without rewriting the business algorithm. Keep enough task context for teams to decide whether a workflow should continue, retry, pause, or move to a project-specific review step. The product does not make that review policy implicit. Move between supported model providers as costs, latency, quality, and requirements change. The agent contract remains the durable interface. Keep enough context to understand why a task succeeded, failed, waited, or retried where the integration records those signals. Security teams can review hosting, subprocessors, access controls, data movement, and requestable review inputs before a project expands.

Python agents that need routing policy, recovery behavior, typed results, task context, and a path from prototype to operated software. Other language-native development, visual agent builders, prebuilt assistant marketplaces, or framework-specific starter packs.

## Developer questions ### How do I get started with the SDK Request Python access from the contact form. Install the `duale` package, set `DUALE_TENANT_ID` and `DUALE_AUTH_TOKEN`, instantiate `DualeSDK(config=DualeConfig())`, and submit a first bounded task with `ask(action=..., res=..., routing=RoutingPolicy(...), deadline=..., sdk=sdk)`. The first agent runs on the evaluation workspace before any production rollout. ### How does provider routing work from the SDK Your code submits a `RoutingPolicy` with target accuracy, guardrails, and speed preference. The runtime scores supported models against the policy and selects one per task; your agent code never calls a model provider directly. Cross-provider discovery and fallback ordering are roadmap, not shipped today. ### What should my application store after submission Persist `response.task_id` — that is the durable correlator for everything your application logs about this task. The terminal result comes back from `await response.model()`, validated against the response model passed to `ask`. On failure, `DualeError.problem_details` carries the RFC 9457 envelope: `error_code`, `detail`, `retryable`, `retry_after_seconds`, and `error_category`. Live content deltas and tool-use events arrive on `response.stream()` while the task runs; if your product needs a retrievable history of those events, store them in your own system as they stream — the SDK does not expose a replay endpoint today. ### How does the SDK handle retries and failures The SDK's HTTP transport reconnects dropped event streams with exponential backoff and jitter; the runtime owns task-level retries within bounded policy. Your code does not implement either layer. Failed tasks return a terminal failure result with an error category and a `retryable` flag; the task identifier links to the routing decision and event history for that attempt. ### When is Duale AI not the right fit yet Duale AI is a runtime, not an agent framework, a model gateway, a model provider, or a managed cloud agent platform. It is not the right fit if you need a non-Python development path, a no-code agent builder, a visual agent builder, a prebuilt assistant marketplace, a framework-specific starter pack, or a packaged employee assistant. The supported surface today is the Python SDK task-submission path: bounded action, routing policy, deadline, typed result, and task identifier. ## Related content - [Production runtime for durable AI agents](https://duale.ai/en/home.md) - [Role-based solutions for platform, business, and governance](https://duale.ai/en/solutions.md) - [Turn AI pilots into a production portfolio](https://duale.ai/en/solutions/business.md) - [Pricing for reliable AI agent orchestration runtime](https://duale.ai/en/product/pricing.md) - [Govern AI agents in production with shared operating signals](https://duale.ai/en/solutions/governance.md) - [Security Trust Center for production AI agents](https://duale.ai/en/product/security.md) --- ## Sitemap See the full [Markdown sitemap](https://duale.ai/sitemap.md) for all pages.
