Fastino's GLiNER2.5-Decide Ships as an Open-Weight Model — Unconfirmed by a Second Source
2026-09-27 · published 13:19 UTC · research report
This week's open-source model search turned up one dated release, Fastino Labs' GLiNER2.5-Decide, which remains backed by a single source; a separate NASA-IBM lunar foundation model announcement falls outside this week's tracking window.
Fastino GLiNER2.5-Decide: this week's one tracked release
Fastino Labs released GLiNER2.5-Decide on September 24, 2026. The model ships as an open-weight release under the Apache 2.0 license, hosted at fastino/GLiNER2.5-Decide. [S3]
This is the only model found this week that both falls inside the September 20-27, 2026 tracking window and has a specific, sourced fact tied to a named model. It rests on a single fetched source, so it is labeled unconfirmed rather than a confirmed trend — a second independent source has not yet turned up to corroborate the release. [S3]
Little else corroborated this week
A "This Week in Open Source" roundup published on the Google Open Source Blog, dated September 24, 2026, was also checked this week. The fetched text confirmed only the post's title and date, not any specific claim about a named model, so it does not corroborate the Fastino release or point to any other project. [S1]
Older news, outside this week's window: NASA-IBM Lunar Foundation Model
Separately, IBM and NASA announced on September 10, 2026 the open-source release of the NASA-IBM Lunar Foundation Model, which the two organizations describe as one of the first publicly available foundation models built specifically for scientific exploration of the Moon. [S2]
That announcement predates this report's September 20-27, 2026 tracking window. Like the Fastino release, it rests on a single fetched source, so it is also flagged as unconfirmed pending a second, independent source. [S2]
