Intelligent Review Model Update

• Submit Review Task
  • Body: The available values of the model parameter are updated to deepseek-v4-pro, qwen3.6-plus, qwen3.7-max, and ORM-O1. 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 statistics now include not_triggered_count, which returns the number of review rules that were not triggered.

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).

• 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).

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.

​

Deprecated Endpoints

The following single-item endpoints are now marked as deprecated. They remain functional but will no longer be maintained. Please migrate to the primary endpoints above:

​

One-Step Category Creation

Create File Category now accepts a tables parameter — configure tables and their fields in a single call when creating a category.

​

Field Advanced Config

Update File Category Field (single + batch) now support these properties:

​

Enriched Responses

Get full config without extra queries:

• Get File Category Field List — added enabled, prompt, use_prompt, extract_model, alias, identity, multi_value, duplicate_value_distinct, transform_settings
• Get File Category Table List — added prompt, collect_from_multi_table, extract_model
• List File Categories — added category_prompt, extract_model
• with_detail flag — pass with_detail=true on create/update to get the complete object in the response
