Best Local LLMs for a Single 24GB GPU in 2026: Qwen, Gemma, Mistral, and DeepSeek Compared

A comprehensive comparative guide evaluates the top local LLMs runnable on a single 24GB GPU in 2026, covering Qwen, Gemma, Mistral, and DeepSeek across capability, speed, and use-case fit. The 24GB tier (covering cards like the RTX 4090 and A5000) is the sweet spot for serious local inference, and having a current, opinionated comparison matters as the model landscape has shifted significantly in the past six months. For developers setting up local development environments, self-hosted inference servers, or offline-capable applications, this kind of benchmark-grounded guide cuts through the noise of marketing claims. The inclusion of DeepSeek and Qwen alongside Western models reflects the reality that Chinese open-weight models now dominate several capability tiers. Developers evaluating local deployment options should treat this as a practical starting point before running their own task-specific evals.
