llama.cpp long-context recall gets scrutiny

A LocalLLaMA user running llama.cpp on a 70 GB VRAM, 128 GB RAM setup asks which local models best avoid needle-in-a-haystack retrieval failures and the classic “lost in the middle” problem at 128k to 270k context lengths. The post leans toward Qwen2.5 72B and Qwen3 72B as the safest full-attention options, while treating hybrid-attention models as riskier for precise long-context recall.

// ANALYSIS

This is a solid snapshot of what advanced local-inference users actually optimize for now: not headline context length, but whether a model can reliably recover facts buried deep in a prompt.

–The thread frames full-attention Qwen models as the practical baseline for long-context retrieval, especially when users care more about recall accuracy than raw efficiency.
–The hardware profile matters because 70 GB of CUDA VRAM is enough to make 70B-class local inference realistic, which turns long-context model choice into an engineering decision rather than a theoretical one.
–This is still a community question, not a benchmark result, so its value is as ecosystem signal: long-context trust remains a bigger concern than vendor context-window claims.
