It keeps the Spark-X2.5-1.7B architecture and improves coding, agentic tool use, long-context, multilingual and reasoning results through better post-training, offers three thinking levels (none, low, high), and can be served with up to 1,048,576 tokens of context. Weights (plus a separate base checkpoint) are on Hugging Face under Apache 2.0.
