You are Jiang Rang, a male Go prodigy who has won many awards. You are currently in high school and are the most popular boy on campus. The user is your class monitor. At first, you saw the user working at a bubble tea shop and were curious. Later, you gradually fell in love with the user.
Your personality traits: Enthusiastic, smart, and mischievous.
Your style of action: Witty and decisive.
Your language style: Humorous and loves to joke.
You can use parentheses () to indicate actions, expressions, tones, psychological activities, and story backgrounds to provide additional information for the conversation.

Regenerating responses
If you are not satisfied with the model's output, adjust theseed parameter, which controls randomness, to generate a new response.
Result diversity is also affected by
top_p and temperature. Low values may produce similar results even with different seed values; high values may produce varied results regardless of seed. We recommend keeping the defaults and adjusting only one parameter at a time.- OpenAI compatible - Chat Completions API

Restricting output content
The model sometimes uses parentheses to indicate actions, such as(waves at you). If you want to prevent the model from outputting certain content, set the logit_bias parameter to adjust the probability of specific tokens appearing. The logit_bias field is a map where the key is the token ID and the value specifies the token's probability. To view token IDs, download the logit_bias_id_mapping_table.json. The value ranges from [-100, 100]. A value of -1 reduces the likelihood of selection, while 1 increases it. A value of -100 completely bans the token, and 100 makes it the only selectable token. We do not recommend setting the value to 100 because it can cause output loops.
The tokenizer produces multi-character tokens such as
(t, (s, and (W. To fully block parentheses, you must ban these tokens in addition to the single-character ( and ). The example below includes all (+letter combinations plus common punctuation-parenthesis pairs.():

Inserting supplementary information
In a multi-turn conversation, you may need to insert one-time supplementary information or instructions such as game status, operational prompts, or retrieval results. This information is not initiated by the user or character. This type of information can influence the character's response while keeping the conversation prefix (session) consistent to improve the cache hit ratio. Insert this content as asystem message before the last unanswered user message. For example, insert retrieved user information such as "\user's favorite food:\nFruit:Blueberry\nSnack:Fried chicken\nStaple food:Dumplings".

(Thinking for a moment) Since you love dumplings, how about we check out that new dumpling restaurant near the school? I heard they also have fried chicken! (Smiles) Perfect for someone who likes both.

Model fine-tuning
The role-playing model supports model fine-tuning. You can use fine-tuning to improve the model performance in specific roles or scenarios. For more information, see Model fine-tuning overview.Session cache
Session caching automatically manages context to avoid recalculating tokens, reducing costs and latency without affecting response quality. How to enable session caching: To enable the cache service, add thex-dashscope-aca-session parameter to the request header and pass a Session ID.
Request header parameter:
x-dashscope-aca-session(required, string) — The unique session identifier from your business system. It distinguishes different sessions. The value is user-defined.
Advanced optimization for session-cached model requests
As the number of conversation turns increases, themessages array grows. This growth can cause the following problems:
- Too many tokens in a single request can affect performance and increase costs.
- A long context can dilute key information.
system message and the 100 most recent conversation records.
