Kimi K3.1 Pro Released: Capabilities Improved, but Price Is 16 Times That of DeepSeek and MiniMax Flash

Moonshot AI released Kimi K3.1 Pro on October 24, retaining K3's 2.8 trillion parameters without redoing pretraining, and raised its Artificial Analysis composite intelligence index from about 44 to about 55 by increasing post-training compute and joint reinforcement learning across hundreds of domains. Its pricing is $2 and $10 per million input/output tokens, or $12 for 1 million tokens each, 16 times the $0.75 idle-time rate of MiniMax M3.1 Flash and DeepSeek V4.1 Flash-1017. The article also compares the three vendors' respective reinforcement in 3D modeling and financial research, full project development, and computer operation and cross-application workflows, and notes that some users report 3D tasks consume tokens so fast that they hit the quota limit.

Kimi K3.1 suspected to appear on Arena, official video reveals model name

Kimi officially released a 24-second video, in which the model field of Kimi Code shows Kimi K3.1; previously an anonymous model Kibitz appeared on Arena and was suspected by netizens to be K3.1. Kibitz performed well in code tests such as 3D courtyard and pelican SVG, and a model-tracking account judged through Tokenizer features that it belongs to the Moonshot AI Kimi model family. Code commits in the SGLang repository show that K3.1 uses the same Tokenizer and 16 special Tokens as K3, and may add a new medium reasoning intensity tier.

MiniMax Breaks Issue Price for First Time in Hong Kong; Zhipu Falls 7.1% on Same Day as LLM Price War Continues

On October 22, MiniMax's Hong Kong shares fell more than 7% intraday, hitting a low of HK$158.10 and closing at HK$160.70, below the HK$165 issue price—its first break below the issue price since listing in January this year; on the same day, Zhipu closed down 7.1% at HK$460.80. MiniMax's share price has pulled back about 88% from its high, while Zhipu has pulled back about 85% from its high, with more than HK$1 trillion in market value wiped out. The article attributes the pullbacks to weakness in Hong Kong stocks and the price war: Zhipu launched GLM-5.3-Flash on August 26, pricing it at one-tenth of the flagship GLM-5.3; OpenAI released the GPT-6 series on September 23 and announced a permanent 50% API price cut; MiniMax released M3.1 Flash on October 19, saying the overall cost of use for Agentic tasks is 70% lower than the previous generation.

MiniMax M3.1 Flash hands-on comparison with Claude Opus 5.5

MiniMax's newly released M3.1 Flash and Claude Opus 5.5 were tested with the same Three.js prompt, and both ran successfully on the first try; M3.1 Flash detected 4 potential rendering errors on its own and fixed them, kept the frame rate steady at 60 fps, and even added a control panel unprompted. M3.1 Flash costs $0.6 per million output tokens and $0.015 for cache reads, is 3x faster than the previous-generation M3 at two-thirds lower cost, and tops Automation-Bench with 62.2, but scores only 38.1 on Terminal Bench 4.0, trailing Opus 5's 51.8.
