Qwen3 14B

The highest listed result may be a tight or offloaded fit. For daily use, prefer the first result marked Confortável and keep context modest.

02 / DEFAULT RUNTIME

Ollama

One-command local chat and app integration. GPU and driver support varies by operating system. Confirm the current hardware matrix before buying hardware. Since v0.34.2 (2026-09-15) Ollama's first-run setup offered account sign-in, and the release notes said you could continue locally; since v0.40.1 (2026-10-07) the CLI Welcome screen completes onboarding on Enter and the intermediate account step is gone, while cloud models keep the sign-in flow. Since v0.40.0 (2026-09-25) Ollama runs MLX-supported model architectures on Apple silicon through MLX by default rather than its own runner; NVIDIA and CPU paths are unchanged.
