Ling 3.1 Flash Free

Ling 3.1 Flash Free is positioned as a no-cost text-to-text model intended for accessible general-purpose assistant workloads. It supports reasoning, tool calling, and temperature control, signaling that it is aimed at agent-style and controllable generation tasks rather than narrow single-turn Q&A. The combination of a zero per-token price and a 262,144-token context window makes it practical for developers experimenting with long-context prompts, multi-step tool workflows, and conversational agents where cost is a primary constraint.

As a member of the Ling family released in late September 2026, the model fits the role of a free-tier entry point that still exposes the longer context and tool-calling surface area typical of the family. Its 32,768-token maximum output ceiling supports extended responses for summarization, code generation, and multi-turn agent loops. The lack of open weights indicates a hosted inference model, with the model key and routing surfaced through the listing provider, while the underlying creator attribution is to inclusionai.
