@rohanpaul_ai Wild seeing cheaper models keeping up with way more expensive options today
GPT-5.6 Sol Ultra vs GPT-5.5 In a surprising HTML5 physics test demo Atomic Chat found GPT-5.6 Sol Ultra is 3X more expensive vs GPT-5.5, but for no clear physics advantage. The test asked each model to write self-contained HTML5 canvas demos for crashes, flips, jumps, and derailments. Outputs: GPT-5.6 Sol Ultra: 32.9K tokens, $0.33 Opus 4.8: 9.2K tokens, $0.24 GPT-5.5: 12.4K tokens, $0.11 Grok 4.5: 7.0K tokens, $0.08 Physics demos expose a weakness that ordinary coding benchmarks often hide: a model can spend more tokens describing a richer scene while still failing the hard part, which is maintaining force, momentum, collision timing, and believable object behavior across frames.
