Pareto / Coding plans
Best AI coding subscription? From $10.
Check three numbers: what you pay, how much work it covers and what happens when you run out. Pareto publishes all three, and works in coding agents that let you set a base URL.
Coding plans
Use either in your coding agent through the Unbiased API, for one person. Weekly and request limits apply.
Tokens are small pieces of words. The bug fix below used 272.
New API accounts require manual approval.
Comparing AI coding subscriptions?
Four numbers to check first.
What you pay
Personal is $10/month and Personal Max is $100/month, billed monthly, for one person.
How much work it covers
Personal includes 50M tokens a week and Personal Max 600M. The bug fix below used 272 tokens.
What happens when you run out
Requests over your plan’s limits return an HTTP 429 error. The allowance is published up front; subscriptions are not unlimited.
How fast it can go
Personal allows 20 requests per minute and Personal Max 60.
One real task
A real bug, fixed and checked.
Prompt
This Python function should return the median of a list of numbers, but this check fails:
def median(values):
s = sorted(values)
return s[len(s) // 2]assert median([4, 1, 3, 2]) == 2.5Find the bug, explain it in one sentence, and give me the fixed function.
Pareto’s answer, unedited
The bug is that for an even-length list, the index len(s) // 2 returns the upper middle element instead of the average of the two middle values.
Here’s the fixed function:
def median(values):
s = sorted(values)
n = len(s)
mid = n // 2
if n % 2 == 0:
return (s[mid - 1] + s[mid]) / 2
else:
return s[mid]The checks (test_median.py, in full)
assert median([4, 1, 3, 2]) == 2.5
assert median([5, 1, 3]) == 3
assert median([7]) == 7
print("all checks passed")Result
$ python3 test_median.py # before the fix
AssertionError
$ python3 test_median.py # after the fix
all checks passedWe pasted the answer's function above the checks and ran them with Python 3. The first check is the one in the prompt; the other two cover an odd-length list and a single value.
Captured October 20, 2026 from the Unbiased API (model pareto, served as Pareto 26.10). 272 tokens (85 prompt, 187 answer), as reported by the API. On pay-as-you-go credits this call cost $0.0007 at the published rates. Raw capture.
The setup
Use it in your coding agent.
Pareto speaks the OpenAI Chat Completions and Anthropic Messages formats (API spec), so a coding agent that lets you set a base URL and a model name can usually use it.
Choose a plan
Create your platform account and pick a plan. New accounts are reviewed by a person before API access turns on. Your API key is issued on the platform once you’re approved.Enter three settings
In your agent’s model or provider settings:Base URL: https://api.unbiased.ai/v1 Model: pareto API key: your Unbiased API key
Agents built on the Anthropic SDK take the base URL without/v1(quickstart):https://api.unbiased.ai
Keep the key in an environment variable or your OS keychain, never in a repo.If your tool lists models

50M tokens/week · 20 requests/minute · one person. New API accounts require manual approval.
Product names belong to their owners. Unbiased is not affiliated with or endorsed by the makers of the coding agents you connect.
One model string.
Several models behind it.
Pareto is Unbiased’s blended AI model: it runs a mix of frontier and open models on each request and blends their outputs into one answer.

Which coding agents work?
Tools that speak the OpenAI Chat Completions or Anthropic Messages format and let you set a base URL and model name can usually connect. Use the base URL https://api.unbiased.ai/v1 and the model string pareto.
What happens when I hit the weekly allowance?
Requests over your plan’s limits return an HTTP 429 error, per the API spec at unbiased.ai/openapi.json. Personal includes 50M tokens a week and 20 requests per minute. Personal Max raises that to 600M a week and 60 requests per minute for $100/month. Team uses prepaid pay-as-you-go credits with no weekly token cap.
Is Pareto a coding agent?
No. Pareto is a model you call with the model string pareto. You keep the coding agent, editor or terminal tool you already use and point it at the Unbiased API.
Is my code kept?
Unbiased Chat, Personal and Personal Max are not part of our Zero Data Retention API. Under section 5(c) of the Terms, prompts and responses on those plans may be kept for up to 30 days for abuse prevention, security monitoring, debugging and product improvement, and our staff may access them. Conversations and Projects you save in Chat are kept until you delete them; otherwise for the length of the contract plus 30 days, or 30 days after a verified account deletion request, whichever is earlier. Standard pay-as-you-go API traffic on Team credits isn’t part of the Zero Data Retention API either: under section 5(c)(i) it may be kept for up to 30 days for abuse prevention and security monitoring. The Zero Data Retention API is described on the Private AI page.
