Opus 5 refined the UI and functions in about 30 minutes for the tableau method calculation tool that I painstakingly created on my own last year.
Also, as I instructed, I made it possible to follow the calculation process dynamically. The tableau method is a deductive system with an easy-to-see formula structure, and this function is expected to help learning (however, handwriting is probably best for learning).
Opus 5 vs DeepSeek v4.1 Flash
Tested both models with same frontend prompt at highest reasoning available but results came out really different opus took 80 minutes to complete and costed $20 v4.1 flash took 60 minutes and costed $0.2 which one did better here?
Up to 20x faster response times on Claude, GPT & Grok!⚡️
We just upgraded our upstream infrastructure at APInex_ai and switched to lightning-fast dedicated routes for our flagship models: ⚡️ Claude (Sonnet 5, Opus 5) ⚡️ GPT (GPT-5.6 Luna / Sol / Terra, GPT-6 Astra) ⚡️ Grok
If there were a metric called “intelligence per second,” deepseek_ai V4.1 Flash would be roughly 3× Opus 5.
Factor in cost, and the advantage becomes ~90×.
