How to control cost (a practical playbook)

Optimizing costs when using Solar Mini involves strategic prompt engineering and understanding its performance characteristics. By implementing a few key practices, you can maximize efficiency and ensure that your AI budget is spent effectively.

The following playbook provides actionable strategies to mitigate potential cost increases and leverage Solar Mini's strengths for various applications.

Context Window Management

Solar Mini's 4k token context window means that every token you send in counts towards your input cost. For tasks where information density is crucial, ensure your prompts are concise and directly relevant. Avoid including unnecessary conversational filler or redundant instructions.

  • Prune Inputs: Before sending a prompt, remove any irrelevant information or historical conversation turns that are no longer critical for the current task.
  • Summarize Prior Context: For multi-turn interactions, summarize previous turns into a compact context rather than sending the full history.
  • Efficient Prompt Design: Craft prompts that are clear, direct, and provide all necessary information without being overly verbose.
Output Control and Guidance

While specific verbosity data is unavailable, you can still guide Solar Mini to produce outputs of an appropriate length, thereby controlling output token costs. Explicitly instruct the model on the desired length or format of the response.

  • Specify Length: Use phrases like "Summarize in 3 sentences," "Provide a short paragraph," or "List 5 key points."
  • Define Format: Request specific formats like bullet points, short answers, or single-sentence responses to naturally limit output length.
  • Iterative Refinement: If initial outputs are too long, refine your prompt to be more restrictive in subsequent calls.
Batching and Asynchronous Processing

Solar Mini's slower output speed (76.1 tokens/s) can be a factor for high-volume tasks. To mitigate this, consider batching multiple requests together and processing them asynchronously, rather than waiting for each individual response.

  • Group Requests: For tasks like generating multiple product descriptions or summarizing several articles, send them in batches to optimize API call overheads.
  • Asynchronous Calls: Implement asynchronous API calls in your application to prevent your system from idling while waiting for responses, improving overall throughput.
  • Queue Management: Utilize message queues to manage and process large volumes of requests efficiently, especially during peak times.
Task Suitability Matching

As a non-reasoning model with below-average intelligence, Solar Mini is best utilized for tasks that align with its capabilities. Using it for complex analytical or highly creative tasks might lead to unsatisfactory results, requiring more re-prompts and thus increasing costs.

  • Identify Core Use Cases: Focus on tasks like summarization, rephrasing, basic content generation, and simple Q&A.
  • Avoid Complex Reasoning: For tasks requiring deep understanding, logical inference, or multi-step problem-solving, consider more capable models to avoid iterative prompting.
  • Pilot Testing: Thoroughly test Solar Mini on your specific use cases to ensure it meets quality requirements without excessive prompt engineering.
Monitoring and Analytics

Regularly monitoring your token usage and costs is crucial for identifying inefficiencies and optimizing your budget. Leverage Upstage's analytics tools or integrate your own tracking mechanisms.

  • Track Token Usage: Keep a close eye on both input and output token counts for different types of requests.
  • Analyze Cost Trends: Identify patterns in your spending to understand which applications or user behaviors are driving costs.
  • Set Alerts: Configure alerts for unusual spikes in token usage or costs to quickly address potential issues.
