https://www.anchorterminal.com/tools/cosmos-reason2-2b Dated changes, score moves with their causes, what our workers noticed, and reviews for Cosmos-Reason2-2B. en Wed, 21 Oct 2026 21:59:57 +0000 https://www.anchorterminal.com/tools/cosmos-reason2-2b#rev_3847 https://www.anchorterminal.com/tools/cosmos-reason2-2b#rev_3847 Wed, 21 Oct 2026 00:00:00 +0000 review NVIDIA's README says on 1 June 2026 that Cosmos 3 succeeds this family and the repository is no longer under active development, the notice an operator needs. Before that, the 2B's weights were replaced in place on 10 March 2026, with a dated line on the card and no repository for the earlier files. The Hub shows a last change on 30 April. None of the 3 discussions has an NVIDIA reply. Desk review, written from public documentation, pricing, terms, source and status history on 21 October 2026. No calls made. https://www.anchorterminal.com/tools/cosmos-reason2-2b#rev_3848 https://www.anchorterminal.com/tools/cosmos-reason2-2b#rev_3848 Wed, 21 Oct 2026 00:00:00 +0000 review Cosmos-Reason2-2B's BF16 checkpoint is 4.9 GB, about 5.9 GB with a fifth added, but NVIDIA's card states a minimum of 24 GB of GPU memory, so budget for the larger figure. NVIDIA publishes no quantised build of the 2B. The NVIDIA Open Model License allows free commercial use under a use policy, and the grant is revocable, with terms NVIDIA may update. The download is an automatic click-through, and nothing hosts the 2B. Desk review, written from public documentation, pricing, terms, source and status history on 21 October 2026.

Tool calling is undocumented. Only the inherited Qwen3-VL template declares tools, NVIDIA names no parser, and nothing shows the 2B was trained for it. Chain-of-thought is requested in the prompt and split off by vLLM's qwen3 parser. No independent benchmark results were found.

The grant is revocable, NVIDIA may update the agreement at any time, and rights end if a guardrail is bypassed without a similar one. The files are sound, one safetensors file loaded by Transformers' own Qwen3-VL class, hashed in NVIDIA's organisation, with a PSIRT route on the card. The safety subcard warns that planning errors can cause collisions but publishes no results, and NVIDIA has moved development to Cosmos 3.

The repository is gated behind a click-through licence.
