88Z AI, 29 April — iFlytek has officially launched the Spark X2-Flash large language model and opened its API. The model uses a MoE architecture with 30 billion total parameters, supports a 256K long context window, and was trained on Huawei Ascend 910B domestic computing clusters. It shows significant improvements in agent and coding capabilities, with performance close to trillion-parameter models, token costs less than one-third of mainstream models, and integration with platforms like AstronClaw and Loomy, com

The update
iFlytek's open platform has officially launched the Spark X2-Flash large language model, simultaneously opening its API service. This model adopts a Mixture of Experts (MoE) architecture with a total of 30 billion parameters and supports an ultra-long context window of up to 256K. Its training was completed entirely using Huawei Ascend 910B domestic computing clusters. In terms of performance, Spark X2-Flash achieves significant leaps in agent interaction and code generation capabilities, with tested results approaching the level of trillion-parameter large models. Meanwhile, its token consumption cost is less than one-third of that of mainstream large models. Currently, the model has been integrated into platforms such as AstronClaw and Loomy, and is compatible with major Agent development frameworks like OpenClaw, providing developers with efficient and low-cost AI solutions.
