Evaluating technical writing capabilities with Kimi-K2 Thinking

📜 YouTube Description

The smartest AI model in the world is now open source.
Today, we’re testing Kimi K2 Thinking — the brand-new open-source large language model that’s competitive with GPT-5 and Claude 4.5 Sonnet on nearly every benchmark that matters. From advanced reasoning and coding to agentic tool use with over 200 consecutive calls, this model proves that open AI is catching up fast.

In this video, we compare Kimi K2 Thinking vs GPT-5 Pro to see how it performs on one of the toughest tests in AI: creative and technical writing. We walk through model setup, context handling, and real-world writing output to see whether Kimi can match or beat closed-source models. Spoiler: it absolutely delivers.

If you’re building AI-powered applications, Kimi K2 Thinking is now available via the Baseten API — making it easy to deploy, scale, and integrate open models into your products. It’s faster, more affordable, and developer-friendly compared to other leading LLMs.
