Kimi K3.1 Pro Price Compared with Opus 5.5 and GPT-6 Astra, Fully Open-Sourced in Early November
The author compared the prices of Kimi K3.1 Pro, Opus 5.5, and GPT-6 Astra: Kimi K3.1 Pro's input, output, and cache-hit prices are all only one-fifth of GPT-6 Astra's, and its input and output prices are also only half of Opus 5.5's. The author states that Kimi K3.1 Pro comprehensively surpasses Opus 5.5 on coding and terminal tests, and will be fully open-sourced in early November. Another tweet cited gives prices of $2 per million tokens for input, $10 for output, and $0.20 for cache hits, with the Highspeed version charging double for both input and output.

Brothers, I seriously can't sleep tonight 😭 I made a comparison chart of Kimi K3.1 Pro, Opus 5.5, and GPT-6 Astra, take a look for yourselves! Kimi K3.1 Pro's input, output, and cache-hit prices are all only one-fifth of GPT-6 Astra's, and Kimi's input and output prices are also only half of Opus 5.5's. I really have to say holy shit here, Damn, how are closed-source models supposed to compete,
Who could have imagined that the technical high wall built by overseas closed-source large models over two years would be completely smashed apart tonight by a 2.8T heavy punch from a domestic team,
Kimi K3.1 Pro completely locks down Opus 5.5 across the board on coding and terminal tests, and directly shows its trump card: full open source in early November!
The era of private deployment of top-tier intelligence is finally here, no more having to look at others' faces ahhhhh 😭
