Kimi K3 analysis reveals higher costs and slower speeds than expected

A developer conducted a cost and performance analysis of Kimi K3 against four other AI models, finding that Kimi K3 was significantly more expensive and slower than anticipated for coding tasks. The analysis revealed that the actual billing rates for models can differ from listed prices, necessitating direct measurement from billing data. The Kimi-K3-codex variant, however, proved to be a cost-effective and faster alternative for coding compared to the base Kimi K3 model. AI

    I metered Kimi K3 against 4 other models from actual billing, not list prices

    <p>Kimi K3 landed two days ago and the timeline is full of parameter counts. I wanted a different number: what does it actually cost to run a real task on it, compared to the alternatives?</p> <p>So I ran the same coding task across five models and metered the cost. The result wa…
