∞ JSON Repair

Documentation

• Class name: LLMJsonRepair
• Category: SALT/Language Toolkit/Tools/JSON
• Output node: False

The LLMJsonRepair node is designed to correct malformed JSON strings using a language model. It takes a potentially incorrect JSON input and optional directions, and outputs a repaired version of the JSON, ensuring data integrity and proper formatting.

Input types

Required

• llm_model
  • Specifies the language model to use for repairing the JSON. It is crucial for interpreting the input and generating the corrected output.
  • Comfy dtype: LLM_MODEL
  • Python dtype: dict
• text_input
  • The malformed JSON string that needs to be repaired. This input is essential for the node to understand what needs fixing.
  • Comfy dtype: STRING
  • Python dtype: str

Optional

• extra_directions
  • Optional additional instructions for the language model to follow during the repair process, allowing for more tailored corrections.
  • Comfy dtype: STRING
  • Python dtype: str

Output types

• json_output
  • Comfy dtype: STRING
  • The repaired JSON string, corrected for syntax and formatting errors to ensure validity.
  • Python dtype: str

Usage tips

• Infra type: CPU
• Common nodes: unknown
