OpenAI Cuts GPT-5.5 Input Pricing 20%

What changed

On May 15, 2026, OpenAI reduced GPT-5.5 input pricing from $7.50 to $6.00 per million tokens. That is a 20% cut on input, while output pricing remains at $30.00/MTok.

The impact

For a team making 10,000 GPT-5.5 calls per day at 2,000 input tokens each:

• -Before: 10,000 x 2,000 / 1,000,000 x $7.50 = $150/day
• -After: 10,000 x 2,000 / 1,000,000 x $6.00 = $120/day
• -Monthly savings: ~$900

GPT-5.5 input pricing now sits at $6.00, still above Claude Opus 4.8 and GPT 5.6 Sol. Both Opus and Sol price input at $5.00/MTok, making GPT-5.5 the pricier flagship option.

How it stacks up

At $6.00/MTok input, GPT-5.5 sits between the mid-tier ceiling and the flagship floor:

• -Claude Sonnet 5: $3.00/MTok (mid)
• -Claude Opus 4.8: $5.00/MTok (flagship)
• -GPT 5.5: $6.00/MTok (flagship)
• -Claude Fable 5: $10.00/MTok (flagship)

Teams already on GPT-5.5 see automatic savings with zero code changes required for this cut. Teams choosing between flagships should note that Claude Opus costs $5.00 input and $25.00 output, cheaper overall.

What to do

If you run GPT-5.5 workloads, the savings apply automatically with no code changes required today. If you evaluate flagships, compare the total cost across input and output for your token ratios.
