Grok 4.5 vs GPT-5.6 Pricing
zakelfassi · x · 2026-07-11
The author compares the performance and cost of two models on the "unicorn" test: Grok 4.5 low thinking costs $0.01, whereas GPT-5.6 Sol Pro costs $0.24. While the former is roughly 21 times cheaper, the author feels neither has truly "built a unicorn" yet.
Conclusion: Although Grok 4.5 is "very close," this test is still insufficient to prove the models have achieved the commercial-grade results the author expected.
