The publisher answered 8 of 13 discussions. The card's head counts and base disagree with the files, and generation_config.json drops the base's end-of-turn stop token. The last file change is the GGUF upload of 22 July. Desk review, written from public documentation, pricing, terms, source and status history on 21 October 2026. No calls made. https://www.anchorterminal.com/tools/darwin-36b-opus#rev_3852 https://www.anchorterminal.com/tools/darwin-36b-opus#rev_3852 Wed, 21 Oct 2026 00:00:00 +0000 review FINAL-Bench's POCKET-35B Q4_K_M GGUF is 21.2 GB, about 25.4 GB with a fifth added, so a 32 GB machine. Its Q3_K_M, Q2_K and IQ1_M files are smaller but below 4-bit, and the BF16 release is 69.4 GB. The card names Apache 2.0 for the merge and both parents, though the repository has no LICENSE file. Nothing is gated, all six runtimes load the architecture, and no provider or API serves it.

No calls made. https://www.anchorterminal.com/tools/darwin-36b-opus#rev_3853 https://www.anchorterminal.com/tools/darwin-36b-opus#rev_3853 Wed, 21 Oct 2026 00:00:00 +0000 review Darwin-36B-Opus keeps Qwen3.6-35B-A3B's chat template, which alone defines tool calls, and the card neither mentions tool calling nor names a parser. Trained tool calling is credited from the base, since the publisher claims and tests none. The template closes the think block when enable_thinking is false, and the card shows how to split the reasoning off, while saying responses always begin with a think trace. No JSON output is documented, and nobody independent has benchmarked the merge. Desk review, written from public documentation, pricing, terms, source and status history on 21 October 2026. No calls made. https://www.anchorterminal.com/tools/darwin-36b-opus#rev_3854 https://www.anchorterminal.com/tools/darwin-36b-opus#rev_3854 Wed, 21 Oct 2026 00:00:00 +0000 review A trust_remote_code flag in Darwin-36B-Opus's example loads nothing, since config.json has no auto_map and the repository holds safetensors and GGUF with no Python. All 21 shards carry a SHA-256 in the FINAL-Bench organisation that vidraft.net links. What went into the weights is less clear. The merge method is proprietary, and the current files include a targeted refinement the card doesn't describe. No safety results, cautions or security contact were found.
