Running a coding builder agent on GTX 1080 Ti 11GB: model candidates tested

NegotiationNo1504 · reddit · 2026-11-08

A Redditor seeks a local LLM to act as a builder agent on GTX 1080 Ti 11GB + 32GB RAM (Debian, llama.cpp/Vulkan since CUDA is unstable), paired with an API planner model to cut costs, targeting 100k+ context. Tested so far: Qwen3.6 35B A3B UD Q4KM (7–10 t/s, under-tested), Qwen3.5-9B MTP (25–30 t/s but inadequate as builder), Sharp Spark X2.5 4B (overthinks, unusable), X2.6 4B (fine for simple tasks only). Asks for working model/quant/harness combos at Q3/Q4 for real agentic coding.
