Safely parse and repair JSON returned by GPT-style models

As developers who have worked with large language models like GPT-3, we're all too familiar with the challenges of handling their output. One common issue is parsing and repairing the JSON data that these models return. This can be a daunting task, especially when dealing with broken or malformed JSON.

The problem

When working with GPT-style models, it's essential to handle the JSON output with care. The problem arises when the model's output is not in a standard format, making it difficult for our applications to parse and understand. This can lead to errors, crashes, or even security vulnerabilities if we're not careful.

One common issue is dealing with SRT (SubRip) or VTT (WebVTT) subtitles that may be included in the model's output. These subtitle formats can be complex and require additional processing to parse correctly. Furthermore, the token budget of these models can be limited, making it essential to compress text to fit within this budget.

LLM Dev Utilities API

The LLM Dev Utilities API offers a solution to these challenges by providing a set of tools that can safely parse and repair JSON data returned by GPT-style models. This API can repair broken model JSON, clean SRT/VTT subtitles, compress text to a token budget, and triage logs – all in a fast, deterministic, and AI-free manner.

What does the request/response look like?

When using the LLM Dev Utilities API, our requests typically consist of a simple JSON payload containing the raw output from the GPT model. The response will then contain the parsed and repaired data, formatted according to our specifications.

Here's an example of what the request might look like:

And here's an example of what the response might look like:

In this example, the raw output from the GPT model contains an invalid subtitle format. The LLM Dev Utilities API receives this data, repairs the subtitle, and returns a parsed and repaired response.
