Vision LLMs and Tool Use: Multimodal Dreams Meet Real-World Constraints

Vision LLMs are colliding with real-world limits. The buzz centers on Qwen3 VL coming next week and Magistral 24B's sharp vision, showing multimodal dreams inching toward reality—yet VRAM and compute budgets are very real.^[1]

What’s lighting up the chat • Qwen3 VL—the next vision model, touted as potentially the best OSS option depending on performance ^[1]. • Magistral 24B—vision capabilities described as top notch ^[1]. • Gemma MOE models—a preferred MOE family topic for speed and efficiency ^[1]. • Gemma 3-27B—MOE that’s small and might fit in tiny VRAM ^[1]. • Gemma 4—hopeful to come with 30B MOE like Qwen3 ^[1]. • Qwen3-30B-A3B and GPT-OSS-20B—sizes people say are worth using around that range ^[1]. • Dense 12b—noted for punching above its weight class ^[1]. • granite-4.0—another vision-capable entry mentioned in the chat ^[1]. • More MOE models in 15-30B size for 8GB VRAM—the hardware constraint nudging model choices ^[1]. • The question of running “30B MOE in 8GB VRAM” pops up as people scope deployment realities ^[1].

Closing thought: the appetite for multimodal tool use is real, but practical device budgets and MOE efficiency will shape what actually ships next.^[1]
