Qwen3 14B

by Alibaba

Qwen3 14B is Alibaba's April 2025 dense model with switchable hybrid reasoning: a thinking mode that exposes step-by-step logic for math, coding, and logical problems, and a non-thinking mode for fast direct responses. Trained on a large multilingual corpus across many languages, it combines reasoning strength with agentic tool use. A 40K context window supports extended reasoning and conversation history, and the model improves on the Qwen2.5 line for mathematics, code generation, and commonsense reasoning while staying lighter than the 235B MoE variant. Released under Apache 2.0, it fits workloads wanting optional visible reasoning chains and cost-efficient agentic systems with tool integration.

Uptime and availability

One of Qwen3 14B's 2 routes is on the monitoring board, so the figure below is that provider's availability rather than the model's.

100%route uptime, last 30 days

Its other routes aren't measured here yet.

Name a second model in the same request and the gateway tries it on retriable errors, so a busy hour never has to reach your users. Set up a fallback chain.

Measured over the last 30 days from each provider's official status feed via StatusGator. Refreshed hourly. 1 further route is not on the board yet. See uptime for every provider Opper monitors.
