September 27, 2022 - This is exactly where RFC-6902 comes to rescue. This specification talks about how the set of instructions can be sent using JSON Patch format for partial update to a resource.

Anyone using “JSON Patch” (RFC 6902) to fix only broken parts of LLM JSON outputs?

Openrouter has something “ response healing ” and I was wondering if they use it. I asked gpt 5.2 pro. It said there’s no public info on their implementation but something maybe relevant: JSON Patch is a patch document format (a sequence of ops like add, remove, replace, etc.) for applying changes to an already-parseable JSON document. It claimed the RFC was a “weird fit for this problem”. 🤷‍♂️ More on reddit.com

APIs in the wild using RFC-6902?

I've implemented JSON PATCH (RFC-6902) in our APIs and it works well. I would provide an example, but our external API Gateway provider still hasn't managed to get PATCH support working, so I've not updated our public documentation with use cases.

January 16, 2020 - The JSON Patch RFC attempts to solve this problem by providing syntax for the intended operations. Ideally we'd find a library that implements RFC 6902 with Jackson and can be added transparently to our existing serialization / de-serialization strategy.

r/LocalLLaMA on Reddit: Anyone using “JSON Patch” (RFC 6902) to fix only broken parts of LLM JSON outputs?

January 12, 2026 -

Hi folks — I’m building a pipeline where an LLM extracts a large structured JSON (100+ items) from documents. I run a deterministic validator (schema + business invariants). When validation fails, I currently ask another LLM call to “fix it”… but it re-outputs the entire JSON, which: • wastes tokens • risks mutating correct fields • makes diffs/debugging painful

I want a patch-based approach: fix ONLY the broken parts.

I’m inspired by the idea of asking the model for JSON Patch (RFC 6902) or some “minimal patch” format instead of regenerating the full object. Also reading this paper: https://arxiv.org/html/2510.04717v1 (JSON editing efficiency).

My current thinking: • Validator pinpoints the failing node(s) • Send the model only a small local context (broken node + parents/children) • Ask for patch ops (e.g., RFC 6902 JSON Patch or domain ops like reparent, set_values) • Apply patch deterministically • Re-validate / retry (bounded)

Another idea would be to grant access to the json file through tools (pydanticAI framework) and ask the agent to repair only the broken part but it seems this is not working

Has anyone shipped this in production? What worked / failed?

If you’ve tested the JSON Whisperer idea (or anything similar), I’d love your results!

I use the json_repair python package rather than the default json to parse llm outputs. No idea how reliable it is though. https://github.com/mangiucugna/json_repair
