Inspired by the iPhone Duo, I reimagined expand/collapse for the web. A glass cover folds open while the content stays flat beneath it. Blur, light, and shadow make a familiar interaction feel a little more physical.

I asked GPT-6-Astra to build a first-person motion simulator. > A 240m cliff dive with underwater sun rays. > A glowing centrifuge tunnel. > A high-speed canyon run with banking turns.

I gave 4 "Flash" models the same job: redact the PII in an HR letter using an agentic mask tool. One of them cost 630× more than another. And it wasn't 630× better. Results 🧵 🥇 GLM 5.3 Flash $0.005, 15 tool calls Clean sweep. Overshot a bit (also redacted employee ID + last-4 of the bank account, which the test didn't require), but zero leaks. Half a cent. 🥈 Qwen 3.8 Flash $0.013, 28 tool calls Clean pass, cleared its markers, and finished the job. 🥉 Gemini 3.8 Flash $3.10, 155 tool calls Passed... eventually. 73 reasoning turns, 3.9M input tokens, an add-mask / remove-mask loop that went on for minutes. Correct result, brutal bill. ❌ DeepSeek V4 Flash Vision $0.053, 31 tool calls Failed. Its own reasoning says "the mask needs to be wider" and "the text is still visible", then it stopped calling tools. Name, DOB, SSN, address, email all partly readable in the final output. Takeaways: > Cheapest model won. Not "won on value", won outright. > Tool-call count predicted cost better than model tier. 155 calls is where the money went. > Seeing the problem ≠ fixing it. DeepSeek diagnosed its own failure correctly and still shipped it. > Total spend for all 4 runs: $3.18. Gemini was $3.10 of that.
