+title: LLMs are bad at returning code in json
+excerpt: LLMs write worse code if you ask them to return the code wrapped in json via a tool/function call.

+# LLMs are bad at returning code in json
+
+
+A lot of people wonder why aider doesn't have LLMs use tools or function calls to
+specify code edits.
+Instead, aider asks LLMs to return code edits in plain text, like this:
+
+````
+greeting.py
+```python
+<<<<<<< SEARCH
+def greeting():
+    print("Hello")
+=======
+def greeting():
+    print("Goodbye")
+>>>>>>> REPLACE
+```
+````
+
+People expect that it would be easier and more reliable
+for aider to parse a nicely formatted json 
+response more like this:
+
+```
+{
+    "filename": "greeting.py",
+    "start_line": 6,
+    "end_line": 7,
+    "new_content": "def greeting():\n    print(\"Goodbye\")\n"
+}
+```
+
+This seems even more tempting as LLMs get better tooling for reliably generating
+valid json, or even enforcing that it meets a specific schema.
+For example, OpenAI recently announced
+[strict enforcement of json responses]().
+
+The problem is that LLMs are bad a writing code when you ask them to wrap it
+into a json container.
+The json tooling around the LLM helps make sure it's valid json,
+which does solve an important problem. 
+LLMs used to frequently produce invalid json, so that's a big step forward.
+
+The problem remains, LLMs write worse code when they're asked to 
+emit it wrapped in json.
+In some sense this shouldn't be surprising.
+Just look at the very simple
+json example above, with the escaped 
+quotes `\"` quotes
+newlines `\n`
+mixed into the code.
+Coding is complicated enough without having to escape all the special characters too.
+
+If I asked you to write me a program, would you do a better job
+typing it into a text file or hand typing it as a properly escaped json string?
+
+## Quantifying the benefits of plain text
+
+
+Previous [benchmark results](/2023/07/02/benchmarks.html)
+showed
+the superiority of plain text coding compared to json-wrapped function calls,
+but they were done over a year ago.
+OpenAI's newly announced support for "strict" json seemed like a good reason to
+investigate whether the newest models are still handicapped by json-wrapping code.
+
+To find out, I benchmarked 3 of the strongest code editing models:
+
+- gpt-4o-2024-08-06
+- claude-3-5-sonnet-20240620
+- deepseek-coder (V2 0724)
+
+Each model was given one try to solve 
+[133 practice exercises from the Exercism python repository](/2023/07/02/benchmarks.html#the-benchmark).
+This is the standard aider "code editing" benchmark, except restricted to a single attempt.
+
+Each model ran through the benchmark with two strategies for returning code:
+
+- **Markdown** -- where the model simply returns the whole source code file in standard markdown triple-backtick fences.
+- **Tool call** -- where the model is told to use a function to return the whole source code file. This requires the LLM to wrap the code in json.
+
+The markdown strategy would return a program like this:
+
+````
+Here is the program you asked for which prints "Hello, world!":
+
+greeting.py
+```
+def greeting():
+    print("Hello")
+```
+````
+
+The tool strategy requires the LLM to call the `write_file` function with
+two parameters, like this:
+
+```
+{
+    "explanation": "Here is the program you asked for which prints \"Hello, world!\"",
+    "content": "def greeting():\n    print(\"Hello\")\n"
+}
+```
+
+Both of these formats avoid actually *editing* source files, to keep things as
+simple as possible.
+This makes the task much easier, since the LLM can emit the whole source file intact.
+LLMs find it much more challenging to correctly formulate instructions to edit
+portions of a file.
+
+We are simply testing the effects of json-wrapping on the LLMs ability to solve coding tasks.
+
+## Results
+
+All 3 models did significantly worse on the benchmark when asked to
+return json-wrapped code in a tool function call.

+## Conclusions
+
+While the quantitative results differ from the similar
+[July 2023 experiments](/2023/07/02/benchmarks.html),
+the conclusion seems unchanged: LLMs are bad at returning code in JSON.
+
+OpenAI appears to be making progress in allowing LLMs to return code in

+But it seems premature to consider switching from plain text
+to JSON-wrapped code.

+## Notes on the aider leaderboard
+
+The results presented here are not directly comparable to results
+from the main
+[aider LLM leaderboard](https://aider.chat/docs/leaderboards/).
+A number of settings were changed to simplify the benchmark
+in order to focus on comparing plain text and JSON wrapped code.

 ## Abstract
 
-The newest LLMs have support for returning properly formatted JSON responses,
-making it easier for clients to parse complex responses.
-This makes it tempting for AI coding applications to
-use JSON replies to
-receive code from LLMs.
+Current LLMs have support for returning properly formatted JSON,
+making it easier for clients to reliably parse complex responses.
+It therefore seems attractive for
+AI coding applications ask LLMs to return code in structure JSON replies.
 Unfortunately, 
 LLMs write worse code when asked to wrap it in JSON, harming their ability
 to correctly solve coding tasks.
 On a variant of the aider code editing benchmark, 
-JSON-wrapping code
+asking for JSON-wrapped code
 often significantly harms coding
-performance
-compared to returning code as plain text.
+performance.
 This holds true across many top coding LLMs, 
-including OpenAI's new gpt-4o-2024-08-06 
+including OpenAI's latest model gpt-4o-2024-08-06 
 which has strong JSON support.
