_is_merge:
type: boolean

description: 'The `_is_merge` field controls how the row is merged with any existing row with the same id in the DB. By default (or when set to `false`), the existing row is completely replaced by the new row. When set to `true`, the new row is deep-merged into the existing row, if one is found. If no existing row is found, the new row is inserted as is.
For example, say there is an existing row in the DB `{"id": "foo", "input": {"a": 5, "b": 10}}`. If we merge a new row as `{"_is_merge": true, "id": "foo", "input": {"b": 11, "c": 20}}`, the new row will be `{"id": "foo", "input": {"a": 5, "b": 11, "c": 20}}`.

For example, say there is an existing row in the DB `{"id": "foo", "input": {"a": {"b": 10}, "c": {"d": 20}}, "output": {"a": 20}}`. If we merge a new row as `{"_is_merge": true, "_merge_paths": [["input", "a"], ["output"]], "input": {"a": {"q": 30}, "c": {"e": 30}, "bar": "baz"}, "output": {"d": 40}}`, the new row will be `{"id": "foo": "input": {"a": {"q": 30}, "c": {"d": 20, "e": 30}, "bar": "baz"}, "output": {"d": 40}}`.

For example, say we have logged a row `{"id": "abc", "input": "foo", "output": "bar", "expected": "boo", "scores": {"correctness": 0.33}}`. We can create a sub-span of the parent row by logging `{"_parent_id": "abc", "id": "llm_call", "input": {"prompt": "What comes after foo?"}, "output": "bar", "metrics": {"tokens": 1}}`.

InsertExperimentEvent:
type: object
properties:
input:
nullable: true
description: The arguments that uniquely define a test case (an arbitrary, JSON serializable object). Later on, Braintrust will use the `input` to know whether two test cases are the same between experiments, so they should not contain experiment-specific state. A simple rule of thumb is that if you run the same experiment twice, the `input` should be identical
output:
nullable: true
description: The output of your application, including post-processing (an arbitrary, JSON serializable object), that allows you to determine whether the result is correct or not. For example, in an app that generates SQL queries, the `output` should be the _result_ of the SQL query generated by the model, not the query itself, because there may be multiple valid queries that answer a single question
expected:
nullable: true
description: The ground truth value (an arbitrary, JSON serializable object) that you'd compare to `output` to determine if your `output` value is correct or not. Braintrust currently does not compare `output` to `expected` for you, since there are so many different ways to do that correctly. Instead, these values are just used to help you navigate your experiments while digging into analyses. However, we may later use these values to re-score outputs or fine-tune your models
error:
nullable: true
description: The error that occurred, if any.
scores:
type: object
nullable: true
additionalProperties:
type: number
nullable: true
minimum: 0
maximum: 1
description: A dictionary of numeric values (between 0 and 1) to log. The scores should give you a variety of signals that help you determine how accurate the outputs are compared to what you expect and diagnose failures. For example, a summarization app might have one score that tells you how accurate the summary is, and another that measures the word similarity between the generated and grouth truth summary. The word similarity score could help you determine whether the summarization was covering similar concepts or not. You can use these scores to help you sort, filter, and compare experiments
