Ant Group Unveils Ling AI Model Family and Launches Trillion-Parameter Language Model Ling-1T

HANGZHOU, China--(BUSINESS WIRE)--Oct 9, 2025--

Ant Group today announced the release and open-sourcing of Ling-1T, a trillion-parameter general-purpose large language model. This launch expands Ant Group’s Ling (also known as BaiLing) model family, which now comprises three main series: the Ling non-thinking models, the Ring thinking models, and the multimodal Ming series.

As a flagship non-thinking model in the Ling family, Ling-1T achieves state-of-the-art (SOTA) performance on multiple complex reasoning benchmarks within constrained output token limits, striking a strong balance between efficient inference and precise reasoning, while delivering improved results across diverse use cases—including code generation, software development, competition-level mathematics problem solving, and logical reasoning.

For example, on the 2025 American Invitational Mathematics Examination (AIME) benchmark, Ling-1T achieves an accuracy of 70.42% at an average cost of over 4,000 output tokens per problem, performing on par with best-in-class AI models.

This follows Ant Group’s release of Ring-1T-preview—the world’s first open-source trillion-parameter thinking model in September.

He Zhengyu, Chief Technology Officer of Ant Group, stated: "At Ant Group, we believe Artificial General Intelligence (AGI) should be a public good—a shared milestone for humanity’s intelligent future. We are dedicated to building practical, inclusive AGI services that benefit everyone, which requires constantly pushing technology forward. The open-source release of Ling-1T and Ring-1T-preview represents a key step in fulfilling our commitment to open and collaborative advancement."

The Ling AI model family now comprises:

Together, these models offer diverse sizes and technical capabilities tailored to various application scenarios.

CHIBA, Japan--(BUSINESS WIRE)--Dec 8, 2025--

Seiko Instruments Inc. (President: Yoichi Endo; Headquarters: Chiba City, Chiba Prefecture; hereinafter “SII”) will begin mass production of the “SC-10S” (32.768kHz), the world’s smallest* tuning-fork crystal resonator measuring 1.0 × 0.8mm, starting in April 2026.
*Based on SII research as of November 2025.

[Background of Development]
SII has already been mass-producing the “SC-12S” (32.768kHz), one of the world’s smallest tuning-fork crystal resonators at 1.2 × 1.0mm. As wearable devices such as smart rings and smartwatches, as well as IoT devices, continue to become smaller, the electronic components built into these devices are increasingly required to support high-density mounting, low power consumption, and high performance. To meet these needs, SII leveraged its proprietary photolithography technology to develop and mass-produce the world’s smallest tuning-fork crystal resonator, the “SC-10S,” which achieves a 33% reduction in mounting area compared to existing models (1.0 × 0.8 × 0.32mm).

[Main Features]
1. World’s Smallest Size
Using SII’s proprietary photolithography technology, which forms fine patterns on quartz wafers, the SC-10S achieves high-precision processing at the world’s smallest size for a 32.768kHz tuning-fork crystal resonator: 1.0 × 0.8 × 0.32mm.

2. Low ESR (90 kΩ max.)
Miniaturization typically leads to an increase in ESR (Equivalent Series Resistance). However, through SII’s proprietary design and manufacturing technologies, the SC-10S maintains a low ESR of 90kΩ max., equivalent to that of existing models.

3. High Shock Resistance and Frequency Stability
The SC-10S ensures excellent frequency stability even in environments subjected to shock or vibration, delivering highly reliable operation.

[Main Applications]
Smart rings, smartwatches, smart tags, hearing aid
Communication modules such as Bluetooth and LPWA
Clock frequency source for RTCs (Real-Time Clocks)
Sub-clock for various microcontrollers

[Production Schedule]
Sample Shipments Begin: December 2025
Mass Production Start: April 2026
