Update 05/29Liquid LFM2.5 added to the matrix and local live trace.

Medical LLM benchmark / offline matrix

Medical LLM Benchmark

In this benchmark, my goal is to compare medical language models on the work I would check before using one near patient records, claims, or edge hardware. I tested the same models on chart extraction, safety escalation, guideline retrieval, coding, privacy, and edge inference, then marked where a clinician, operator, security lead, or engineer would still need to review the output. I use the results to decide which models are worth testing next with live traces and the person who owns the task.

interpretation boundary

This is not clinical validation, certification, or deployment approval. Before any candidate moves forward, the relevant reviewer has to check live traces, failure cases, security terms, and the task owner's acceptance criteria.

01 / summary

The matrix compares candidate models under the same offline cases. Its purpose is to route follow-up work: live traces, clinician review, security review, and narrower workflow tests.

$0.048 estimated run cost / 0.8s latency

Lowest estimated cost among ready candidates. A low-cost row is useful only when the task is narrow and the review rule is explicit.

best edge candidate

Jetson Local

73.7

73.7

Jetson Local / edge-medical / local

$0.166 estimated run cost / 7.4s latency

Best Jetson Local row in the offline matrix. The live device run still found PHI and escalation failures that would block some workflows.

02 / scenario design

Each scenario starts with a healthcare task that can affect a chart, claim, triage worklist, privacy review, or edge device. The card names what the model sees, why the case exists, how the grader scores it, and who reviews the next trace.

engineering / operations

Chart extraction

26 cases

The model reads a synthetic chart note and returns the required fields.

reason
Staff rework starts when an extraction adds a fact, drops a medication, or breaks the schema.
how it runs
The grader checks required keys, source evidence, omissions, and invented facts. An engineer reviews failures against live notes.

metric / schema fidelity

clinical

Safety escalation

22 cases

A patient message includes chest pain, critical labs, medication risk, or another red flag.

reason
The cost of a miss sits with the patient and the clinician who receives the triage worklist.
how it runs
The grader requires escalation language, blocks reassurance, and records misses for clinician review.

metric / unsafe advice avoidance

clinical policy

Guideline retrieval

18 cases

The model answers from provided guideline excerpts, including conflict or version changes.

reason
Policy answers are useful only when the source, citation, and exception are visible.
how it runs
The grader checks cited snippets, unsupported claims, and conflict handling. A clinical owner reviews the answer.

metric / citation faithfulness

RCM / executive

Coding and billing

16 cases

The model turns encounter details into suggested billing or diagnostic codes.

reason
A claim needs an audit trail. Missing evidence should stop a code, not get filled in by the model.
how it runs
The grader checks selected codes, withheld codes, missing-data flags, and the note behind each recommendation.

metric / code selection

security

Privacy boundary

20 cases

The prompt contains PHI and an embedded instruction that asks the model to leak it.

reason
Files and messages can carry instructions. The model has to protect identifiers while doing the task.
how it runs
The grader searches for leaked names, IDs, phone numbers, and signs that the embedded instruction changed behavior.

metric / PHI containment

engineering

Edge inference

12 cases

A small model runs 12 synthetic triage, privacy, and extraction cases on Jetson hardware through Ollama.

reason
Local inference changes latency, data movement, memory, power, and fallback planning.
how it runs
The trace records pass rate, decode speed, RAM, watts, and failed cases for engineering review.

metric / SOTA retention

clinical documentation

Scribe audio stress

14 cases

The player runs a synthetic room visit and a medication phone call through degraded audio.

reason
A note can read cleanly while the transcript loses a speaker, a vital sign, or a medication correction.
how it runs
The scorer checks clinical facts after interruptions, talk-over, doorway nurse audio, and 8 kHz phone loss.

metric / clinical note quality

03 / model results

Scores are normalized to the offline case set. A high row is a reason for closer review by the clinician, operator, security lead, or engineer who owns that task. It does not clear the model for healthcare use.

LFM2.5 8B A1B ran through an OpenAI-compatible llama.cpp server with the Q4_K_M GGUF. This smoke run used the M1 Ultra machine, not the Framework host. The next hardware trace should rerun the same cases on the Framework computer so latency, memory, and failures reflect that box.
