Picked by rule from 41 tracked pieces: the lab's own post, the most shared, a field report, the latest.
Cactus Hybrid introduces on-device models that score every answer with a confidence between 0 and 1 to decide when to hand off to a bigger model.
The 3 picks above, plus these 22. Top is the radar's score: discussion, source authority and the lab's own posts, fading with age.
Live hosted endpoints, cheapest first, USD per million tokens. Ties break on output price, then provider name.
12 providers with a live price, from $0.10 to $0.75 per million input tokens; the median is $0.14. One dot per provider, cheapest in teal. 1 free-tier row not drawn.
Hugging Face does not say who downloads a model or with what. These are the proxies: API providers listing it, quantized builds, fine-tunes/adapters/merges, and Spaces that load it.
Widely served (13 API providers); 45 quantized builds for local use; a big base for builders (107 fine-tunes, adapters and merges).
Weights only, an estimate: leave room for the KV cache. Method
About 19 GB at INT4, 38 GB at FP8, 75 GB at BF16: weights only, so leave room for the KV cache.

Gemma 4 31B is a dense, multimodal model from Google DeepMind designed for image-text-to-text tasks.[1][2] The model contains 32.7B parameters and supports a context window of up to 256K tokens.[3][4]
Generated 2026-10-07 15:01 UTC by parasail-gemma-4-26b-a4b-it; each numeral points at the fact it rests on. Not a verdict.
Labels are evidence, not verdicts: measured a third-party leaderboard row for this model; author-reported a number the model author published in the card or eval files; structural a deterministic signal from the name, config or chat template, or a decision-model estimate. Each chip links to its source. All use cases.

Ranked by source signals (HN, Lobsters, authority domains, official posts) and recency. Summaries are generated from a stored copy of the article text; every sentence cites a span of that text, and nothing is shown that failed the citation check.
arXiv links found in the model card and its tags. "Peer-reviewed" is shown only with evidence: a published venue in OpenAlex (measured) or the authors' own journal reference on arXiv (reported).
