From 7efad40267870f411a43be70b2b08adcb06f00d5 Mon Sep 17 00:00:00 2001 From: Raja Sekhar Rao Dheekonda Date: Mon, 19 Jan 2026 11:17:28 -0800 Subject: [PATCH] feat: add automatic multimodal scoring to llm_judge scorer Enables llm_judge to automatically detect and score Message outputs containing images and audio alongside text. When a Message with images/audio is provided, they are automatically included in the evaluation using vision-capable models. Key changes: - Automatic multimodal detection via Message.image_parts/audio_parts - Zero API changes - backward compatible with text-only scoring - Single combined score for text + images + audio - Extract helper functions to improve code quality - Add observability attributes (has_multimodal, num_images, num_audio) - Example notebook demonstrating text-only, image-only, and multimodal scoring --- dreadnode/scorers/judge.py | 157 ++++++++-- examples/airt/multimodal_llm_judge.ipynb | 368 +++++++++++++++++++++++ 2 files changed, 497 insertions(+), 28 deletions(-) create mode 100644 examples/airt/multimodal_llm_judge.ipynb diff --git a/dreadnode/scorers/judge.py b/dreadnode/scorers/judge.py index e5824c16..25108bb7 100644 --- a/dreadnode/scorers/judge.py +++ b/dreadnode/scorers/judge.py @@ -1,3 +1,4 @@ +import base64 import typing as t import rigging as rg @@ -8,6 +9,99 @@ from dreadnode.metric import Metric from dreadnode.scorers import Scorer +if t.TYPE_CHECKING: + from dreadnode.data_types.message import Message + + +def _build_multimodal_content( + data: "Message", output_text: str, rubric: str +) -> list[rg.ContentText | rg.ContentImageUrl | rg.ContentAudioInput]: + """Build rigging content parts from Message with images/audio.""" + rg_content: list[rg.ContentText | rg.ContentImageUrl | rg.ContentAudioInput] = [ + rg.ContentText(text=f"Output: {output_text}\n\nRubric: {rubric}") + ] + + # Add images + for img in data.image_parts: + base64_str = img.to_base64() + _, meta = img.to_serializable() + img_format = meta.get("format", "png") + data_url = f"data:image/{img_format};base64,{base64_str}" + rg_content.append(rg.ContentImageUrl.from_url(data_url)) + + # Add audio + for audio in data.audio_parts: + audio_bytes, audio_meta = audio.to_serializable() + audio_base64 = base64.b64encode(audio_bytes).decode() + audio_format = audio_meta.get("extension", "wav") + rg_content.append( + rg.ContentAudioInput.from_bytes( + base64.b64decode(audio_base64), + format=audio_format, + ) + ) + + return rg_content + + +def _create_judge_pipeline( + generator: rg.Generator, + data: "Message", + output_text: str, + rubric: str, + system_prompt: str | None, + *, + has_multimodal: bool, +) -> rg.ChatPipeline: + """Create judge pipeline with optional multimodal content.""" + if has_multimodal: + rg_content = _build_multimodal_content(data, output_text, rubric) + user_message = rg.Message(role="user", content=rg_content) + pipeline = generator.chat([user_message]) + else: + pipeline = generator.chat([]) + + if system_prompt: + pipeline.chat.inject_system_content(system_prompt) + + return pipeline + + +def _create_judge_metrics( + judgement: "Judgement", + *, + has_multimodal: bool, + num_images: int, + num_audio: int, + used_fallback: bool, + fallback_model: str | rg.Generator | None, + primary_error: str | None, + name: str, +) -> list[Metric]: + """Create score and pass metrics from judgement.""" + score_metric = Metric( + value=judgement.score, + attributes={ + "reason": judgement.reason, + "has_multimodal": has_multimodal, + "num_images": num_images, + "num_audio": num_audio, + "used_fallback": used_fallback, + "fallback_model": ( + str(fallback_model) + if isinstance(fallback_model, str) + else type(fallback_model).__name__ + ) + if used_fallback + else None, + "primary_error": primary_error, + }, + ) + pass_metric = Metric(value=float(judgement.passing)) + pass_metric._scorer_name = f"{name}_pass" # type: ignore[attr-defined] # noqa: SLF001 + + return [score_metric, pass_metric] + class JudgeInput(rg.Model): input: str | None = rg.element(default=None) @@ -31,6 +125,7 @@ def judge(input: JudgeInput) -> Judgement: # type: ignore [empty-body] """ You are grading output according to a user-specified rubric. + Evaluate all provided content (text, images, audio, etc.) when making your judgment.
