Stop paying premium prices for simple AI tasks.

Stop paying premium prices for simple AI tasks.

I analyzed 50,000 API calls from production. Here's what I found.

The breakdown

  • 42% were classification tasks ("Is this positive or negative?")
  • 31% were summarization ("Summarize this email thread")
  • 18% were simple generation ("Write a tweet about X")
  • 9% were complex reasoning ("Debug this race condition")

Every single one went to the same $7/M model.

A "yes/no" classification costs the same as debugging a 500-line function.
That's not just wasteful — it's lazy architecture.

The fix: two-line routing 

import openai
client = openai.OpenAI(
    api_key="mb-xxx",
    base_url="https://aibridge-api.com/v1"
)

model = "deepseek-chat" if task in ["classify","summarize","simple"]
                         else "glm-4-plus"
client.chat.completions.create(model=model, messages=messages)
Enter fullscreen mode Exit fullscreen mode

Same endpoint. Same code. Different model string for different workloads.

The numbers

Task Calls/month Old cost New cost
Classify (42%) 21,000 $1,491 $56
Summarize (31%) 15,500 $1,101 $418
Generate (18%) 9,000 $639 $243
Reason (9%) 4,500 $320 $320
Total 50,000 $3,551 $1,037

71% cost reduction. Quality unchanged — because the cheap model handles classification,
summarization, and simple generation indistinguishably from the expensive one.

The one-line migration 

curl https://aibridge-api.com/v1/chat/completions \
  -H "Authorization: Bearer mb-xxx" \
  -d '{"model":"deepseek-chat","messages":[...]}'

curl https://aibridge-api.com/v1/chat/completions \
  -H "Authorization: Bearer mb-xxx" \
  -d '{"model":"kimi-k3","messages":[...]}'
Enter fullscreen mode Exit fullscreen mode

DeepSeek (0.27/M).Qwen(from0.40/M). GLM-4 Plus ($7.10/M). Kimi K3 1M context.
Same key. Same endpoint. Change one string.

I found the breakdown of API calls fascinating, especially the fact that 71% of the costs were reduced by simply routing tasks to different models based on their complexity, as seen in the two-line routing code snippet: model = "deepseek-chat" if task in ["classify","summarize","simple"] else "glm-4-plus". This approach highlights the importance of understanding the specific requirements of each task and selecting the most suitable model to avoid overpaying for unnecessary complexity. The use of a cheaper model like "deepseek-chat" for classification, summarization, and simple generation tasks, which handles these tasks indistinguishably from the more expensive "glm-4-plus" model, is a great example of optimizing resource utilization. Have you considered exploring other optimization strategies, such as implementing a more dynamic model selection process based on real-time task analysis?
