Open source model signals

2026-10-10 · reviewer verdict: pass (confidence 0.6) · run 47d07fee

Only one model passed both qualification gates. Ranked list (model, count of distinct fetched sources, confidence): 1. Beam, count 1, noise/unconfirmed (RANKED). Not ranked: Aleph Alpha Kolibri is EXCLUDED: publication date unverified. Unverified lead: Mistral Large 4 (search snippet only). Unverified lead: EmbeddingGemma-2 (search snippet only). Only one qualifying source (s1) exists and no model has a count of 2 or more, so the report cannot separate signal from noise yet. Recommendation: more_evidence.

Models, most corroborated first

RANKED, count 1, noise/unconfirmed. s1 describes it as a sparse Mixture-of-Experts model built for coding, reasoning, and agentic workloads. No second fetched source reports the same signal.

What people are saying

Beam (RANKED, count 1, noise/unconfirmed): s1 is dated October 5, 2026 and introduces Beam as Reflection's first open-weight model, a sparse Mixture-of-Experts model with 501 billion total parameters and 23 billion active. [s1]

Caveats

Fewer than 2 RANKED models and fewer than 3 qualifying sources: only s1 qualifies, so the recommendation is more_evidence.
Beam: RANKED, count 1, noise/unconfirmed; s1 supports text does not state a licence or weights link, so its open-weight status rests on the vendor's own wording.
Aleph Alpha Kolibri: EXCLUDED: publication date unverified; s2 supports text is title-only, does not state a date or licence, and counts for nothing.
Unverified lead: Mistral Large 4 (search snippet only)
Unverified lead: EmbeddingGemma-2 (search snippet only)
Fetched datacamp.com: no usable body (retained text is navigation and promo only), so nothing from it is cited.
Fetched mistral.ai: no usable body (retained text is navigation only), so nothing from it is cited.
Fetched infoq.com: no usable body (retained text is navigation only), so nothing from it is cited.
Could not open huggingface.co (2 model-card URLs) or news.ycombinator.com (2 item URLs): fetch_page denied them because they were not returned by a prior web_search in this run.
No Reddit or Hacker News thread was fetched, and the Reddit-targeted search returned no usable Reddit thread, so community sentiment is not covered.
Economics fields are zero placeholders with no sourced pricing, cost or demand data.
retrieved_at is set to the report time because the exact fetch times were not recorded.
