Pricing Configuration (prices.yaml)

Configure token pricing for different LLM models to track and estimate API costs during UFO² execution.

Overview

The prices.yaml file defines the cost per 1,000 tokens for different LLM models. UFO² uses this information to calculate and report the estimated cost of task executions.

File Location: config/ufo/prices.yaml

Pricing May Be Outdated

The pricing information in this file may not be current. LLM providers frequently update their pricing.

Always verify current pricing on provider websites
This file will be updated periodically
Use these values as estimates only

Quick Start

View Current Pricing

# config/ufo/prices.yaml
gpt-4o:
  prompt: 0.0025
  completion: 0.01

gpt-4o-mini:
  prompt: 0.00015
  completion: 0.0006

gpt-4-turbo:
  prompt: 0.01
  completion: 0.03

Add Your Model

# Add pricing for your custom model
my-custom-model:
  prompt: 0.001      # USD per 1K prompt tokens
  completion: 0.003  # USD per 1K completion tokens

Configuration Format

Structure

Each model has two pricing fields:

model-name:
  prompt: <cost_per_1k_prompt_tokens>
  completion: <cost_per_1k_completion_tokens>

Field	Type	Unit	Description
`prompt`	Float	USD/1K tokens	Cost per 1,000 input (prompt) tokens
`completion`	Float	USD/1K tokens	Cost per 1,000 output (completion) tokens

Common Models (As of Template)

Verify Current Pricing

These prices are from the template and may be outdated. Always check provider websites for current pricing:

OpenAI Models

Model	Prompt ($/1K)	Completion ($/1K)	Notes
`gpt-4o`	$0.0025	$0.01	Latest GPT-4 optimized
`gpt-4o-mini`	$0.00015	$0.0006	Cheaper alternative
`gpt-4-turbo`	$0.01	$0.03	GPT-4 Turbo
`gpt-4-vision-preview`	$0.01	$0.03	GPT-4 with vision
`gpt-3.5-turbo`	$0.0005	$0.0015	GPT-3.5

Example Configuration

# OpenAI Models
gpt-4o:
  prompt: 0.0025
  completion: 0.01

gpt-4o-mini:
  prompt: 0.00015
  completion: 0.0006

gpt-4-turbo:
  prompt: 0.01
  completion: 0.03

gpt-4-vision-preview:
  prompt: 0.01
  completion: 0.03

gpt-3.5-turbo:
  prompt: 0.0005
  completion: 0.0015

# Claude Models (example)
claude-3-5-sonnet-20241022:
  prompt: 0.003
  completion: 0.015

# Gemini Models (example)
gemini-2.0-flash-exp:
  prompt: 0.0
  completion: 0.0

Cost Tracking

UFO² automatically tracks costs when pricing information is available.

During Execution

# UFO² automatically calculates costs
Session logs show:
- Total prompt tokens used
- Total completion tokens used
- Estimated cost (based on prices.yaml)

View Cost Summary

After task execution, check logs:

logs/<session-id>/cost_summary.json

Example output:

{
  "total_cost_usd": 0.15,
  "prompt_tokens": 5000,
  "completion_tokens": 2000,
  "model": "gpt-4o"
}

Updating Pricing

Step 1: Check Current Pricing

Visit your LLM provider's pricing page:

OpenAI: https://openai.com/pricing
Azure OpenAI: https://azure.microsoft.com/pricing/details/cognitive-services/openai-service/
Anthropic: https://www.anthropic.com/pricing
Google: https://ai.google.dev/pricing

Step 2: Update prices.yaml

# Update with current pricing
gpt-4o:
  prompt: 0.0025  # Update if changed
  completion: 0.01

Step 3: Add New Models

# Add newly released models
gpt-5:
  prompt: 0.005
  completion: 0.02

Programmatic Access

from config.config_loader import get_ufo_config

config = get_ufo_config()

# Get pricing for a specific model
model_name = "gpt-4o"
if model_name in config.prices:
    prompt_cost = config.prices[model_name]["prompt"]
    completion_cost = config.prices[model_name]["completion"]
    print(f"{model_name}:")
    print(f"  Prompt: ${prompt_cost}/1K tokens")
    print(f"  Completion: ${completion_cost}/1K tokens")
else:
    print(f"No pricing info for {model_name}")

Cost Estimation Example

# Example: Estimate cost for a task
prompt_tokens = 10000      # 10K prompt tokens
completion_tokens = 5000   # 5K completion tokens
model = "gpt-4o"

# Get pricing
prompt_cost_per_1k = 0.0025
completion_cost_per_1k = 0.01

# Calculate
total_cost = (
    (prompt_tokens / 1000) * prompt_cost_per_1k +
    (completion_tokens / 1000) * completion_cost_per_1k
)

print(f"Estimated cost: ${total_cost:.4f}")
# Output: Estimated cost: $0.0750

Notes

Important Notes

✅ Pricing is for cost estimation only, not billing
✅ Actual costs may vary based on your provider contract
✅ Different Azure regions may have different pricing
✅ Some models have tiered pricing based on volume
✅ Prices change frequently - update regularly

Agent Configuration - LLM model selection
System Configuration - Token limits and usage

Summary

Key Takeaways

✅ prices.yaml tracks LLM costs - Estimates API spending
✅ Pricing may be outdated - Always verify current rates
✅ Update regularly - Providers change pricing frequently
✅ Add new models - Include pricing for any custom models
✅ Cost tracking is automatic - UFO² calculates costs during execution

Keep pricing updated for accurate cost tracking! 💰
