+## Some tips:
+If you’re using the DeepSeek API provided by the official website, you might encounter an “exceeding context” error after several rounds of conversation (since the official API only supports a 64K context window). In this case, you’ll need to discard the previous context and start fresh. Alternatively, you can use ByteDance’s DeepSeek API, which offers a 128K context window and supports KV cache.
+
+Note: claude code consumes a huge amount of tokens, but thanks to DeepSeek’s low cost, you can use claude code at a fraction of Claude’s price, and you don’t need to subscribe to the Claude Max plan.
+
+Some interesting points: In my testing, providing absolute context information can help bridge the gap between these models. For example, when I used Claude 4 in VS Code Copilot to handle a Flutter issue, after three rounds of conversation it kept messing up the files, and I had to roll back in the end. But when I switched to claude code using DeepSeek, after three or four rounds of conversation, I finally completed my task—and the cost was less than 1 RMB!
