Starting July 8, 2026, the following legacy models were deprecated. Use the corresponding replacement model: | Legacy model | Replacement model | | ------------- | ----------------- | | `deepseek-r1` | `deepseek-v4-pro` | | `qwq-32b` | `qwen3.6-plus` | | `qwen3-max` | `qwen3.7-max` | * **Response**: Added the `model` field, which returns the model actually used for the review task. * [Get Review Task Result](/api-reference/intelligent-review/get-review-task-result) statistics now include `not_triggered_count`, which returns the number of review rules that were not triggered. ## 2026-07-05 ### API #### Extraction Model Upgrade The extraction models have been uniformly renamed, and a new **Auto** intelligent routing option has been added. This affects all endpoints that contain `extract_model` (**Create File Category**, **Update File Category**, adding and updating file category fields/tables, **Extract Fields**, **Get File Results**). | Old Model Name | New Model Name | Description | | -------------- | -------------- | ------------------------------------------------------------------------------------------------------------------ | | Model 1 | `Acgpt` | Fast speed with stable extraction results | | Model 2 | `DF-M1` | Suitable for complex document understanding | | Model 3 | `Acgpt-VL` | VLM, suitable for simple extraction (≤10 pages) | | — | `Auto` | Automatically matches the extraction model (new; the algorithm automatically routes to the actual model per field) | * The request parameter `extract_model` only accepts the new model names (`Auto`/`Acgpt`/`Acgpt-VL`/`DF-M1`); the old values `Model 1`/`Model 2`/`Model 3` and the legacy code values `llm`/`vlm` are no longer supported. * In the **Get File Results** and **Extract Fields** responses, fields and tables now include `configModel` (the configured model, which may be `Auto`; `null` for legacy data that was not configured); the original `extractModel` semantics have been adjusted to "actual hit model" (values `Acgpt`/`Acgpt-VL`/`DF-M1`). * A new extraction failure reason "Exceeded Acgpt-VL processing limit" has been added (`Acgpt-VL` has a document-level processing cap, surfaced when e.g. the page count exceeds the limit). * The extraction model `Acgpt-VL` does not currently support table multi-table merging (`collect_from_multi_table`). ## 2026-06-02 ### API #### Primary Endpoints Upgrade Process multiple objects in a single request. All endpoints use **all-or-nothing** semantics — if any item fails validation, the entire batch is rejected. | Endpoint | Description | | ----------------------------------------------------------------------------------------------------- | ------------------------------------ | | [Add File Category Fields](/api-reference/file-category/add-file-category-fields) | Create up to 100 fields at once | | [Update File Category Fields](/api-reference/file-category/update-file-category-fields) | Update multiple field configs | | [Add File Category Tables](/api-reference/file-category/add-file-category-tables) | Create tables (with embedded fields) | | [Update File Category Tables](/api-reference/file-category/update-file-category-tables) | Update multiple table configs | | [Upload Category Samples](/api-reference/file-category-samples/upload-category-samples) | Upload multiple samples (up to 20) | | [Download Category Samples (ZIP)](/api-reference/file-category-samples/download-category-samples-zip) | Download samples as ZIP | #### Deprecated Endpoints The following single-item endpoints are now marked as `deprecated`.
