[Feature]: Support for iFlytek's Newly Open-Sourced Edge-Side Models (Spark X2.5-4B & 1.7B)

Suggestion Description

Background

I'm a long-time user of iFlytek's products, particularly their Smart Office Book X5. The device is powered by iFlytek's edge-side models, which have been specifically fine-tuned for meeting transcription and light office tasks. In my experience, the performance on these specialized tasks is quite impressive.

Why These Models Matter

These models, being compact and efficient, appear to be well-suited for always-on deployment on NPUs like ours, which could enable seamless, day-to-day office assistance directly on the device. The X5 itself leverages a powerful NPU, demonstrating the viability of this approach.

The Opportunity

I'm excited to see that iFlytek has just open-sourced two of these edge-side models today (September 1, 2026):

Spark X2.5-4B
Spark X2.5-1.7B

A key feature is their native support for a 1 million token context window, which is quite advanced for edge-side models.

Given their proven performance in office scenarios, optimization for edge deployment, and now open-source availability, I believe these models would be a valuable addition to [Your Inference Engine's Name]'s supported model list. They could open up new possibilities for on-device AI assistance.

Would the team be interested in evaluating these models for future support?

Thanks for considering!

The issue provides links to the Spark X2.5-4B and 1.7B models but names no files or tests. Start by evaluating those models against FastFlowLM's supported-model scope; done should be a clear decision on whether support is feasible and what follow-up is required.
