Gemma 4: Byte for byte, the most capable open models

Gemma 4: Byte for byte, the most capable open models Four new vision-capable Apache 2.0 licensed reasoning LLMs from Google DeepMind, sized at 2B, 4B, 31B, plus a 26B-A4B Mixture-of-Experts. Google emphasize "unprecedented level of intelligence-per-parameter", providing yet more evidence that creating small useful models is one of the hottest areas of research right now. They actually label the two smaller models as E2B and E4B for "Effective" parameter size. The system card explains: The…

datasette-llm-usage 0.2a0

Release: datasette-llm-usage 0.2a0 Removed features relating to allowances and estimated pricing. These are now the domain of datasette-llm-accountant.

Quoting Soohoon Choi

I want to argue that AI models will write good code because of economic incentives. Good code is cheaper to generate and maintain. Competition is high between the AI models right now, and the ones that win will help developers ship reliable features fastest, which requires simple, maintainable code. Good code will prevail, not only because we want it to (though we do!), but because economic forces demand it. Markets will not reward slop in coding, in the long-term. — Soohoon Choi, Slop Is…

Supply Chain Attack on Axios Pulls Malicious Dependency from npm

Supply Chain Attack on Axios Pulls Malicious Dependency from npm

Supply Chain Attack on Axios Pulls Malicious Dependency from npm Useful writeup of today's supply chain attack against Axios, the HTTP client NPM package with 101 million weekly downloads. Versions 1.14.1 and 0.30.4 both included a new dependency called plain-crypto-js which was freshly published malware, stealing credentials and installing a remote access trojan (RAT). It looks like the attack came from a leaked long-lived npm token. Axios have an open issue to adopt trusted publishing, which…

llm-all-models-async 0.1

Release: llm-all-models-async 0.1 LLM plugins can define new models in both sync and async varieties. The async variants are most common for API-backed models - sync variants tend to be things that run the model directly within the plugin. My llm-mrchatterbox plugin is sync only. I wanted to try it out with various Datasette LLM features (specifically datasette-enrichments-llm) but Datasette can only use async models. So... I had Claude spin up this plugin that turns sync models into async…

llm 0.30

llm 0.30

Release: llm 0.30 The register_models() plugin hook now takes an optional model_aliases parameter listing all of the models, async models and aliases that have been registered so far by other plugins. A plugin with @hookimpl(trylast=True) can use this to take previously registered models into account. #1389 Added docstrings to public classes and methods and included those directly in the documentation.
