## Stories
- [DeepSeek separated stable V3.2 tool use from the temporary V3.2-Speciale endpoint](https://rangoon.ai/insights/archive-deepseek-v3-2-speciale-december-2025/)
  DeepSeek launched stable V3.2 and the API-only V3.2-Speciale on December 1, 2025, separating tool-enabled modes from a temporary reasoning variant.
- [DeepSeek-V3.2-Exp put sparse attention into an experimental API upgrade](https://rangoon.ai/insights/archive-deepseek-v3-2-exp-september-2025/)
  DeepSeek updated its chat and reasoner endpoints to V3.2-Exp on September 29, 2025, presenting DeepSeek Sparse Attention as a long-context experiment.
- [DeepSeek-V3.1 joined thinking modes, long context, and tool calls in one release](https://rangoon.ai/insights/archive-deepseek-v3-1-august-2025/)
  DeepSeek released DeepSeek-V3.1 on August 21, 2025, describing Think and Non-Think modes, 128K context, updated tokenizer materials, and beta strict function calling.
- [DeepSeek-R1-0528 made reasoning updates a token-budget decision](https://rangoon.ai/insights/archive-deepseek-r1-0528-update-2025/)
  DeepSeek released R1-0528 on May 28, 2025 with stated benchmark, function-calling, and hallucination changes. A reasoning gain can also change tokens, latency, and tool behavior.
