Open source model signals

2026-09-27 · reviewer verdict: pass (confidence 0.7) · run 8a9904d9

Ranked list (fetched-source count, confidence, most-corroborated first): 1) Fastino GLiNER2.5-Decide — count=1, confidence=noise/unconfirmed (S3: open-weight model under Apache 2.0 license, released September 24, 2026, inside the Sept 20-27, 2026 window). NASA-IBM Lunar Foundation Model is EXCLUDED: dated outside window (S2 gives an announcement date of September 10, 2026) and is therefore not in the ranked list or competitors. Of 3 fetched pages (S1, S2, S3), only S3 is both dated inside the window and states a specific fact about a named qualifying model; the gate requiring ≥2 qualifying models and ≥3 qualifying sources is not met, so this run recommends more_evidence. The 3-web-search budget was used in full without surfacing a Reddit thread or a second qualifying model.

Models, most corroborated first

What people are saying

• Fastino Labs released GLiNER2.5-Decide, an open-weight model under the Apache 2.0 license, on September 24, 2026 — inside the Sept 20-27, 2026 window. [S3]

Caveats

• NASA-IBM Lunar Foundation Model: EXCLUDED: dated outside window — S2 gives an announcement date of September 10, 2026, before the Sept 20-27, 2026 window, so it is not in the ranked list or competitors despite S2 stating it is open-source (weights on Hugging Face, code on GitHub).
• Only 1 qualifying model (Fastino GLiNER2.5-Decide, RANKED, count=1) and 1 qualifying source (S3) were found this run; the gate requiring ≥2 qualifying models and ≥3 qualifying sources is not met, so recommendation is more_evidence.
• S1 (Google Open Source Blog roundup) counts for nothing toward the qualifying-source minimum: the fetched text confirmed only its title and September 24, 2026 date, not a specific fact about a named model.
• No Reddit thread (r/LocalLLaMA, r/MachineLearning, r/OpenSource) appeared among this run's three web searches, so Reddit sentiment could not be assessed this run.
• A second independent fetched source for Fastino GLiNER2.5-Decide was not found within the 3-web-search budget used this run.
