1. Clinician use of language models diverges from how the models are evaluated

Why this matters: Hospital leaders and benchmark builders can compare their own assistant's usage logs with the tests they rely on, since the authors found the median of 58 public benchmarks they assembled shared only 31% of the task mix of one system's real use.

Summary: This preprint from a New York health system studies 127,833 queries that 6,342 physicians, advanced practice providers such as nurse practitioners and physician assistants, and nurses sent to an in-house AI assistant over about eight months. The authors labeled each query with a clinician-checked framework, using an AI model as the labeler. Documentation and administration (36.2%) and knowledge retrieval (28.9%) made up nearly two-thirds of use, while diagnosis was 3.7%, and 36.1% of queries could not be answered well as asked. Across 58 public benchmarks, the median one shared 31% of the real task mix (less than an even spread across task categories would) and had no documentation requests. The authors note it covers one system and one assistant, only the first message was labeled, and clinicians agreed only modestly on risk.

2. Same Query, Different Answer: Run-to-Run Variance in Semantic Query Processing

Authors: Oktie Hassanzadeh et al.

Why this matters: Benchmark designers and engine builders can check whether their per-query comparisons survive repeated runs.

Summary: This arXiv experimental study re-runs the text and table workloads of three benchmarks for database queries that ask a language model to judge rows (SemBench, LRO-Bench, UDA-Bench), logging about 1.2 million model calls. At temperature 0, the authors report that between 0.07% and 10.2% of rows change their output over five executions, depending on the model, and up to 24.0% on one task. On UDA-Bench, a few percent of extracted values change but about two thirds of the answers do. In SemBench's published results, 21% of text results change quality between executions. The authors also report that 16 of 28 tests of LRO-Bench's recommendations are not settled by its executions, and that voting reduces the variance but does not remove it.

3. web-edit 0.1a0

Why this matters: People who let AI coding agents work on their machines can see one developer's early alpha for editing a credentials file without passing its contents through the model.

Summary: This is a release note on Simon Willison's blog for an early alpha tool. Willison writes that while working from his phone he wanted to edit a credentials file without sending those credentials through the language model. He says he had Codex and a GPT-6 model build a Python web app that offers a web page for viewing and editing files in a folder. It is meant to run over Tailscale, so an agent can start it and he can edit files from his phone over his own network. He notes the editor uses CodeMirror 6.

4. ttok 1.0

Why this matters: Developers who count tokens to estimate cost or fit text into a model's limit should note that OpenAI has not confirmed that GPT-6 uses the same tokenizer as GPT-5.

Summary: This is a release note on Simon Willison's blog for version 1.0 of his ttok tool. He writes that after releasing 0.4 he noticed it still defaulted to the GPT-4 tokenizer, so he switched the default to the GPT-5 and GPT-6 one and called it 1.0. He states that OpenAI has not confirmed that GPT-6 uses the same tokenizer as the GPT-5 family, and he links to an issue about it. He points to a commit by William Liu that reports an experiment suggesting the tokenizers are likely the same. So the only support he cites for the tokenizers matching is that outside experiment, not an OpenAI statement.
