Unsloth ends TQ1_0 quant production

Unsloth's UD-TQ1_0 quants were the last practical bridge between frontier-scale MoE models and consumer hardware — their quiet removal closes a door the local LLM community deeply relied on.

• –TQ1_0 was the only format enabling models like Qwen3.5-397B and DeepSeek-R1 671B to fit in 128GB Mac unified memory; no equivalent replacement exists at that size-to-RAM ratio
• –Unsloth gave no detailed explanation — just "we have decided to remove 1-bit models from now on" — with hosting costs for 200GB+ multi-file uploads the most plausible driver
• –Community members have already started preserving quants independently, with a backup of Qwen3.5-397B TQ1_0 uploaded to HuggingFace within hours
• –Unsloth's recommended alternative is UD-Q2_K_XL (2.7-bit), which offers better accuracy but demands meaningfully more RAM
• –Existing TQ1_0 quants remain on HuggingFace; only new releases are affected
