Question 1

What is the current OpenAI API pricing?

Accepted Answer

As of 2026: GPT-4o costs $2.50/1M input, $10/1M output. GPT-4o-mini costs $0.15/1M input, $0.60/1M output. o1-preview costs $15/1M input, $60/1M output. o1-mini costs $1.75/1M input, $7/1M output. GPT-3.5 Turbo costs $0.50/1M input, $1.50/1M output. Prices are per million tokens.

Question 2

Which OpenAI model should I use for cost optimization?

Accepted Answer

Use GPT-4o-mini for routine tasks (classification, extraction, simple chat) at $0.15-0.60/1M tokens. GPT-4o for complex reasoning at $2.50-10/1M. Reserve o1 models for math and coding challenges only. The mini version handles 90% of applications at 5% of premium model cost.

Question 3

How does OpenAI pricing compare to other providers?

Accepted Answer

OpenAI GPT-4o-mini ($0.15-0.60/1M) is competitive with Claude Haiku ($0.25-1.25/1M) and Gemini Flash ($0.075-0.30/1M). Gemini Flash is cheapest for high-volume tasks. Claude Sonnet ($3-15/1M) offers better value than GPT-4o for moderate complexity tasks. Compare based on your actual token profile.

Question 4

What are OpenAI's rate limits and how do they affect costs?

Accepted Answer

Rate limits vary by tier: Free tier 3 RPM/40K TPM. Tier 1: 500 RPM/30K TPM. Tier 2: 5,000 RPM/100K TPM. Higher tiers available for enterprise. Rate limit errors trigger retries, increasing latency and cost. Plan request distribution and implement backoff strategies to stay within limits.

Question 5

Does OpenAI offer volume discounts?

Accepted Answer

OpenAI offers no automatic volume discounts on API usage. Enterprise customers can negotiate custom pricing for high-volume commitments ($100K+/year). The Volume Program provides committed-use pricing with lower rates. Contact sales for enterprise agreements. Otherwise, optimize by choosing cheaper models.
