# Exa Deep Revamp

> Exa Deep is now faster, adds deep-reasoning, and supports structured outputs with field-level grounding.

***

**Date: March 4, 2026**

## What's New

* **Greatly improved performance** for Exa Deep workloads.
* **Latency ranges**:
  * `deep`: 4 to 12 seconds
  * `deep-reasoning`: 12 to 50 seconds
* **New search type: `deep-reasoning`** for higher-effort reasoning tasks.
* **20% lower price for regular `deep`** search.
* **Structured outputs for Deep** using output schemas. Built to provide web grounded fields perfect for enrichments.
* **New request schema controls**: `type`, `description`, and `properties` on `outputSchema` (`output_schema` in Python SDK).
* **New synthesized response fields**: `output.content` and `output.grounding`.

## Structured Outputs

For deep search variants (`deep`, `deep-reasoning`), you can define the output shape using:

* `outputSchema` in JavaScript/TypeScript and REST
* `output_schema` in Python

Supported schema controls include:

* `type`
* `description`
* `properties`

```json theme={null}
{
  "query": "top aerospace companies",
  "type": "deep-reasoning",
  "outputSchema": {
    "type": "object",
    "properties": {
      "companies": {
        "type": "array"
      }
    }
  }
}
```

## Deep Output Response Shape

Deep responses now include:

* `output.content` for synthesized text or structured JSON
* `output.grounding` for field-level citations and confidence

```jsonc theme={null}
// Query: Top aerospace companies and their CEO's name
"output": {
  "content": {
    "companies": [
      {
        "ceo_name": "Christopher T. Calio",
        "company_name": "RTX Corporation"
      },
      {
        "ceo_name": "Kelly Ortberg",
        "company_name": "Boeing"
      },
      ...
    ]
  },
  "grounding": [
    {
      "field": "companies[0].ceo_name",
      "citations": [
        {
          "url": "https://fintool.com/app/research/companies/RTX/people/christopher-t-calio",
          "title": "Christopher Calio - Executive Profile & Compensation"
        },
        ...
      ],
      "confidence": "high"
    }
  ]
}
```

## Pricing Update
