The models were the easy part; getting them to run meant forking llama.cpp because upstream never added support.
Why now: The fork requirement surfaced in this r/LocalLLaMA post as of August 31, 2026.
One developer spent a month building uncensored quants for five niche local models, then had to write the runtime code to run them.
None of it runs on mainline llama.cpp. Getting the 1M-context window these releases promise means installing one person's fork instead.
The release covers LongCat-Flash-Lite-Sparse, Qwen3.8-27B, Qwen3.5-122B-A10B with MTPs, Qwen3-Coder-Next, and Laguna-S2.1 with vision support, according to a month of solo work posted to r/LocalLLaMA. LongCat-Flash-Lite-Sparse needed new architecture support in Heretic, the uncensoring tool, before quantization could start. Then came llama.cpp support for that same architecture, written from scratch, since mainline never added it.
Architecture support doesn't ship with the model release. Someone has to write it, and right now that's one person, unpaid, across five models in a month. If they stop maintaining the fork, every GGUF built against it stops working with anything newer.
The post doesn't say whether any of this gets upstreamed to llama.cpp, or whether the author plans to keep maintaining the fork after this release.
