Task Group

The Parallel Task Group API enables you to batch process hundreds or thousands of Tasks efficiently. Instead of running Tasks one by one, you can organize them into groups, monitor their progress collectively, and retrieve results in bulk. The API is comprised of the following endpoints: Creation: To run a batch of tasks in a group, you first need to create a task group, after which you can add runs to it, which will be queued and processed.

POST /v1/tasks/groups (Create task-group)
POST /v1/tasks/groups/{taskgroup_id}/runs (Add runs. Up to 1,000 runs per POST request.)

Progress Snapshot: At any moment during the task, you can get an instant snapshot of the state of it using GET /{taskgroup_id} and GET /{taskgroup_id}/runs. The runs endpoint streams back the requested runs immediately using SSE to support large payloads without pagination; it does not wait for runs to complete. Task Group runs are subject to your account’s data-retention configuration. Persist any results your application needs after processing; Zero Data Retention (ZDR) deployments do not retain completed run data.

GET /v1/tasks/groups/{taskgroup_id} (Get task-group summary)
GET /v1/tasks/groups/{taskgroup_id}/runs (Fetch task group runs)
GET /v1/tasks/groups/{taskgroup_id}/runs/{run_id} (Retrieve one task run’s status)

Realtime updates: You may want to provide efficient real-time updates to your app. For group status updates and non-active run state events, you can use GET /{taskgroup_id}/events. To retrieve a completed task run’s result, use the task run result endpoint.

GET /v1/tasks/groups/{taskgroup_id}/events (Stream task-group events)
GET /v1/tasks/runs/{run_id}/result (Get task-run result)

To determine when a task group has no active runs, you can either use realtime update events or poll the task-group summary endpoint. You can continue adding runs to a task group after it becomes inactive.

Key Concepts

Task Groups

A Task Group is a container that organizes multiple task runs. Each group has:

A unique taskgroup_id for identification
A status object with is_active (boolean) and task_run_status_counts (counts by status)
The ability to add new Tasks dynamically

Group Status

Track progress with real-time status updates:

Total number of task runs
Count of runs by status (queued, action_required, running, completed, failed, cancelling, or cancelled)
Whether the group is active (is_active is true while any run is queued, running, or cancelling)

An inactive group has no active runs, but its runs may have completed, failed, been cancelled, or require action. Inspect task_run_status_counts to distinguish those outcomes.

Quick Start

1. Define Types and Task Structure

# Define task specification as a variable
TASK_SPEC='{
  "input_schema": {
    "json_schema": {
      "type": "object",
      "properties": {
        "company_name": {
          "type": "string",
          "description": "Name of the company"
        },
        "company_website": {
          "type": "string",
          "description": "Company website URL"
        }
      },
      "required": ["company_name", "company_website"]
    }
  },
  "output_schema": {
    "json_schema": {
      "type": "object",
      "properties": {
        "key_insights": {
          "type": "array",
          "items": {"type": "string"},
          "description": "Key business insights"
        },
        "market_position": {
          "type": "string",
          "description": "Market positioning analysis"
        }
      },
      "required": ["key_insights", "market_position"]
    }
  }
}'

import pydantic
from parallel import AsyncParallel
from parallel.types import TaskSpecParam, JsonSchemaParam
from parallel.types.run_input_param import RunInputParam

# Define your input and output models
class CompanyInput(pydantic.BaseModel):
    company_name: str = pydantic.Field(description="Name of the company")
    company_website: str = pydantic.Field(description="Company website URL")

class CompanyOutput(pydantic.BaseModel):
    key_insights: list[str] = pydantic.Field(description="Key business insights")
    market_position: str = pydantic.Field(description="Market positioning analysis")

# Create reusable task specification
task_spec = TaskSpecParam(
    input_schema=JsonSchemaParam(json_schema=CompanyInput.model_json_schema()),
    output_schema=JsonSchemaParam(json_schema=CompanyOutput.model_json_schema()),
)

import Parallel from "parallel-web";

// Define your input and output types
interface CompanyInput {
  company_name: string;
  company_website: string;
}

interface CompanyOutput {
  key_insights: string[];
  market_position: string;
}

// Use SDK types for Task Group API
type TaskGroupObject = Parallel.TaskGroup;
type TaskGroupStatus = Parallel.TaskGroupStatus;
type TaskGroupRunResponse = Parallel.TaskGroupRunResponse;
type TaskGroupEventsResponse = Parallel.TaskGroupEventsResponse;
type TaskGroupGetRunsResponse = Parallel.TaskGroupGetRunsResponse;

// Create reusable task specification using SDK types
const taskSpec: Parallel.TaskSpec = {
  input_schema: {
    type: "json",
    json_schema: {
      type: "object",
      properties: {
        company_name: {
          type: "string",
          description: "Name of the company",
        },
        company_website: {
          type: "string",

        },
      },
      required: ["key_insights", "market_position"],
    },
  },
};

2. Create a Task Group

# Create task group and capture the ID
response=$(curl --request POST \
  --url https://api.parallel.ai/v1/tasks/groups \
  --header 'Content-Type: application/json' \
  --header "x-api-key: ${PARALLEL_API_KEY}" \
  --data '{}')

# Extract taskgroup_id from response
TASKGROUP_ID=$(echo $response | jq -r '.taskgroup_id')
echo "Created task group: $TASKGROUP_ID"

# Initialize the client
client = AsyncParallel()

# Create a new task group
task_group = await client.task_group.create()

taskgroup_id = task_group.task_group_id
print(f"Created task group: {taskgroup_id}")

// Initialize the client
const client = new Parallel({
  apiKey: process.env.PARALLEL_API_KEY,
});

// Create a new task group
const groupResponse = await client.taskGroup.create({});

const taskgroupId = groupResponse.taskgroup_id;
console.log(`Created task group: ${taskgroupId}`);

3. Add Tasks to the Group

By default, the response refreshes and returns the aggregated status of all runs in the group. If you’re adding tasks at scale, set refresh_status to false to skip the full status refresh — the response still includes a status snapshot from the group’s atomically maintained counters. You can refresh the aggregated status at any time via the GET task-group endpoint.

curl --request POST \
  --url https://api.parallel.ai/v1/tasks/groups/${TASKGROUP_ID}/runs \
  --header 'Content-Type: application/json' \
  --header "x-api-key: ${PARALLEL_API_KEY}" \
  --data '{
  "default_task_spec": '$TASK_SPEC',
  "inputs": [
    {
      "input": {
        "company_name": "Acme Corp",
        "company_website": "https://acme.com"
      },
      "processor": "pro"
    },
    {
      "input": {
        "company_name": "TechStart",
        "company_website": "https://techstart.io"
      },
      "processor": "pro"
    }
  ]
}'

# Prepare your inputs
companies = [
    {"company_name": "Acme Corp", "company_website": "https://acme.com"},
    {"company_name": "TechStart", "company_website": "https://techstart.io"},
    # ... more companies
]

# Create task run inputs
run_inputs = [
    RunInputParam(
        input=CompanyInput(**company).model_dump(),
        processor="pro",
    )
    for company in companies
]

# Add runs to the group
response = await client.task_group.add_runs(
    taskgroup_id,
    inputs=run_inputs,
    default_task_spec=task_spec,
)

print(f"Added {len(response.run_ids)} Tasks to group")

// Prepare your inputs
const companies = [
  { company_name: "Acme Corp", company_website: "https://acme.com" },
  { company_name: "TechStart", company_website: "https://techstart.io" },
  // ... more companies
];

// Create task run inputs using SDK types
const runInputs: Array<Parallel.RunInput> = companies.map((company) => ({
  input: {
    company_name: company.company_name,
    company_website: company.company_website,
  },
  processor: "pro",
}));

// Add runs to the group
const response = await client.taskGroup.addRuns(taskgroupId, {
  default_task_spec: taskSpec,
  inputs: runInputs,
});

console.log(`Added ${response.run_ids.length} Tasks to group`);

4. Monitor Progress

# Get status of the group
curl --request GET \
  --url https://api.parallel.ai/v1/tasks/groups/${TASKGROUP_ID} \
  --header "x-api-key: ${PARALLEL_API_KEY}"

# Get status of all runs in the group
curl --request GET \
  --no-buffer \
  --url https://api.parallel.ai/v1/tasks/groups/${TASKGROUP_ID}/runs \
  --header "x-api-key: ${PARALLEL_API_KEY}"

import asyncio

async def wait_until_inactive(client: AsyncParallel, taskgroup_id: str) -> None:
    while True:
        task_group = await client.task_group.retrieve(taskgroup_id)

        status = task_group.status
        print(f"Status: {status.task_run_status_counts}")

        if not status.is_active:
            print("No active runs remain.")
            break

        await asyncio.sleep(10)

asyncio.run(wait_until_inactive(client, taskgroup_id))

async function waitUntilInactive(
  client: Parallel,
  taskgroupId: string
): Promise<void> {
  while (true) {
    const response = await client.taskGroup.retrieve(taskgroupId);

    const status = response.status;
    console.log("Status:", status.task_run_status_counts);

    if (!status.is_active) {
      console.log("No active runs remain.");
      break;
    }

    await new Promise((resolve) => setTimeout(resolve, 10000));
  }
}

async function main() {
  const client = new Parallel({ apiKey: process.env["PARALLEL_API_KEY"] });
  // ... create task group and get taskgroupId ...
  await waitUntilInactive(client, taskgroupId);
}

main();

5. Retrieve Results

The getRuns endpoint returns a Server-Sent Events stream, not a simple JSON response. It emits one event per run currently in the group (a snapshot of each run’s state), then closes. To pick up runs added after that snapshot, resume from the last event_id via the last_event_id parameter. Each event in the stream has:

type: Either "task_run.state" or "error"
event_id: Cursor for resuming the stream via the last_event_id parameter
run: The TaskRun object with run_id, status, and is_active
input: The original input (only included when include_input=true)
output: The result output (only included when include_output=true and the run completed successfully)

If you want a live stream of non-active run state transitions and group-level status updates instead of a snapshot, use the /events endpoint shown below the getRuns examples.

# Snapshot of each run's current state (matches the Python/TS getRuns examples)
curl --request GET \
  --no-buffer \
  --url "https://api.parallel.ai/v1/tasks/groups/${TASKGROUP_ID}/runs?include_input=true&include_output=true" \
  --header "x-api-key: ${PARALLEL_API_KEY}"

# Live stream of non-active run-state + group-status events (stays open while runs are active)
curl --request GET \
  --no-buffer \
  --url https://api.parallel.ai/v1/tasks/groups/${TASKGROUP_ID}/events \
  --header "x-api-key: ${PARALLEL_API_KEY}"

from parallel.types.task_run_event import TaskRunEvent
from parallel.types.error_event import ErrorEvent

# Stream all results from the group
async def get_all_results(client: AsyncParallel, taskgroup_id: str):
    results = []

    run_stream = await client.task_group.get_runs(
        taskgroup_id,
        include_input=True,
        include_output=True,
    )

    async for event in run_stream:
        if isinstance(event, TaskRunEvent) and event.output and event.input:
            company_input = CompanyInput.model_validate(event.input.input)
            company_output = CompanyOutput.model_validate(event.output.content)

            results.append(
                {
                    "company": company_input.company_name,
                    "insights": company_output.key_insights,
                    "market_position": company_output.market_position,
                }
            )
        elif isinstance(event, ErrorEvent):
            print(f"Error: {event.error}")

    return results

results = await get_all_results(client, taskgroup_id)
print(f"Processed {len(results)} companies successfully")

// Stream all results from the group
async function getAllResults(
  client: Parallel,
  taskgroupId: string
): Promise<
  Array<{ company: string; insights: string[]; market_position: string }>
> {
  const results: Array<{
    company: string;
    insights: string[];
    market_position: string;
  }> = [];

  // Use the SDK's streaming API
  const runStream = await client.taskGroup.getRuns(taskgroupId, {
    include_input: true,
    include_output: true,
  });

  for await (const event of runStream) {
    // Handle task run events
    if (event.type === "task_run.state" && event.output && event.input) {
      const input = event.input.input as unknown as CompanyInput;
      const output = (event.output as Parallel.TaskRunJsonOutput)
        .content as unknown as CompanyOutput;

      results.push({
        company: input.company_name,
        insights: output.key_insights,
        market_position: output.market_position,
      });
    }
  }

  return results;
}

const results = await getAllResults(client, taskgroupId);
console.log(`Processed ${results.length} companies successfully`);

Batch Processing Pattern

For large datasets, process Tasks in batches to optimize performance. Setting refresh_status to false is recommended when adding tasks in bulk, as it skips refreshing the group status on each request for faster responses:

async def process_companies_in_batches(
    client: AsyncParallel,
    taskgroup_id: str,
    companies: list[dict[str, str]],
    batch_size: int = 500,
) -> None:
    total_created = 0

    for i in range(0, len(companies), batch_size):
        batch = companies[i : i + batch_size]

        # Create run inputs for this batch
        run_inputs = [
            RunInputParam(
                input=CompanyInput(**company).model_dump(),
                processor="pro",
            )
            for company in batch
        ]

        # Add batch to group (skip status refresh for faster bulk adds)
        response = await client.task_group.add_runs(
            taskgroup_id,
            inputs=run_inputs,
            default_task_spec=task_spec,
            refresh_status=False,
        )
        total_created += len(response.run_ids)

        print(f"Processed {i + len(batch)} companies. Created {total_created} Tasks.")

async function processCompaniesInBatches(
  client: Parallel,
  taskgroupId: string,
  companies: Array<{ company_name: string; company_website: string }>,
  batchSize: number = 500
): Promise<void> {
  let totalCreated = 0;

  for (let i = 0; i < companies.length; i += batchSize) {
    const batch = companies.slice(i, i + batchSize);

    // Create run inputs for this batch using SDK types
    const runInputs: Array<Parallel.RunInput> = batch.map((company) => ({
      input: {
        company_name: company.company_name,
        company_website: company.company_website,
      },
      processor: "pro",
    }));

    // Add batch to group (skip status refresh for faster bulk adds)
    const response = await client.taskGroup.addRuns(taskgroupId, {
      default_task_spec: taskSpec,
      inputs: runInputs,
      refresh_status: false,
    });

    totalCreated += response.run_ids.length;

    console.log(
      `Processed ${i + batch.length} companies. Created ${totalCreated} Tasks.`
    );
  }
}

Error Handling

The /runs stream is a snapshot and can include active runs. Classify each event using event.run.status, not merely by whether an output is present:

async def process_with_error_handling(client: AsyncParallel, taskgroup_id: str):
    successful_results = []
    unsuccessful_results = []
    unresolved_results = []

    run_stream = await client.task_group.get_runs(
        taskgroup_id,
        include_input=True,
        include_output=True,
    )

    async for event in run_stream:
        if isinstance(event, ErrorEvent):
            unsuccessful_results.append(event)
            continue

        if not isinstance(event, TaskRunEvent):
            continue

        if event.run.status == "completed" and event.output:
            try:
                # Validate the result
                company_output = CompanyOutput.model_validate(event.output.content)
                successful_results.append(event)
            except Exception as e:
                print(f"Validation error: {e}")
                unsuccessful_results.append(event)
        elif event.run.status in {"failed", "cancelled", "completed"}:
            # A completed run without output is also unsuccessful.
            unsuccessful_results.append(event)
        else:
            # queued, running, cancelling, or action_required
            unresolved_results.append(event)

    print(
        f"Success: {len(successful_results)}, "
        f"Unsuccessful: {len(unsuccessful_results)}, "
        f"Unresolved: {len(unresolved_results)}"
    )
    return successful_results, unsuccessful_results, unresolved_results

async function processWithErrorHandling(
  client: Parallel,
  taskgroupId: string
): Promise<{
  successful: Array<Parallel.TaskGroupGetRunsResponse>;
  unsuccessful: Array<Parallel.TaskGroupGetRunsResponse>;
  unresolved: Array<Parallel.TaskGroupGetRunsResponse>;
}> {
  const successful: Array<Parallel.TaskGroupGetRunsResponse> = [];
  const unsuccessful: Array<Parallel.TaskGroupGetRunsResponse> = [];
  const unresolved: Array<Parallel.TaskGroupGetRunsResponse> = [];

  const runStream = await client.taskGroup.getRuns(taskgroupId, {
    include_input: true,
    include_output: true,
  });

  for await (const event of runStream) {
    if (event.type === "error") {
      unsuccessful.push(event);
      continue;
    }

    if (event.run.status === "completed" && event.output) {
      successful.push(event);
    } else if (
      event.run.status === "failed" ||
      event.run.status === "cancelled" ||
      event.run.status === "completed"
    ) {
      // A completed run without output is also unsuccessful.
      unsuccessful.push(event);
    } else {
      // queued, running, cancelling, or action_required
      unresolved.push(event);
    }
  }

  console.log(
    `Success: ${successful.length}, Unsuccessful: ${unsuccessful.length}, Unresolved: ${unresolved.length}`
  );
  return { successful, unsuccessful, unresolved };
}
