DeepSeek releases V4.1 Flash multimodal model; OpenCode makes its $60 usage quota permanent and fully integrates it

A new V4.1 Flash model from DeepSeek uses a 552B-parameter mixture-of-experts architecture that activates 8B parameters on input and 16B on output, with a causal encoder-decoder design and native multimodal visual understanding. DeepSeek says its KV cache lowers HBM demand to a quarter of the previous generation and SSD demand to an eighth.

OpenCode began phase two of “Operation Cheepseek” on September 25, making the model's previously time-limited $60 usage quota permanent. OpenCode, an official DeepSeek partner, has fully integrated V4.1 Flash; as of September 25, the model accounted for about 13% of the roughly 2 million usage events OpenCode observed, ranking first.
