Aleph Alpha's Kolibri 1 is the best-corroborated open-weights release in this week's scan

2026-10-07 · published 13:00 UTC · research report

Three sources report the Apache 2.0 release of Kolibri 1, while a community Qwen3.5-based preview rests on a single page and stays unconfirmed.

Kolibri 1: the most widely reported release

Kolibri 1 from Aleph Alpha is the model with the most sources behind it in this run. Its Hugging Face model card lists the license as Apache 2.0 and the release date as 3rd of October 2026. [S1]

A write-up dated Oct 5, 2026 describes Kolibri 1 as Aleph Alpha's specialized bilingual large language model, released on October 3, 2026, under Apache 2.0. That matches the model card on both the date and the license. [S4]

A third source is a developer forum thread. Its poster says the model was "just released today" and describes it as a 78B MoE with 3,5B active parameters, written that way in the thread, under Apache 2.0. The report does not state the thread's publication date. [S5]

How solid the signal is

Kolibri 1 has three sources (S1, S4, S5), which makes it a signal and the top-ranked model in this report. The confidence is a little lower than the raw count suggests, because S4 is an editorial write-up of the same release and is not fully independent. The model card (S1) and the forum thread (S5) still stand as two independent sources. [S1] [S4] [S5]

The 78B and 3,5B-active figures appear only in the forum thread (S5) among the excerpts in this report. Treat them as single-source details until they are checked against the model card. The thread also includes one commenter who expects their employer's customers to ask for the model. That is anecdotal, not a measure of demand. [S5]

Unconfirmed: Jeff-Qwen3.5-0.8B

Jeff-Qwen3.5-0.8B has one source, so it is noise or unconfirmed under this report's scoring. Its page describes a community preview, v1.2 (1 October 2026), with nine LoRA adapters. The weights are Apache 2.0, from Qwen3.5-0.8B by the Qwen team, Alibaba Cloud. [S2]

The same page says the model is superseded, comes from an earlier Jeff release, and is no longer updated. Local users should not read the 1 October date as a sign of active development. [S2]

What this scan does not cover

Only two models made the ranked list: Kolibri 1 with three sources and Jeff-Qwen3.5-0.8B with one. That is too little data to show a trend across open models. No Reddit thread was fetched, so community sentiment on r/LocalLLaMA, r/MachineLearning and r/OpenSource is not covered. [S1] [S4] [S5] [S2]

One roundup page (S3) names other models. They are each reported by that single roundup, so they are unconfirmed, and this article does not assess them. [S3]
