Grok 4

Elon Musk's xAI company has released the next version of its large language model. In their presentation, they used one of the ways to manipulate statistics, by cropping one axis to make the difference seem much more significant. Possibly other descriptions of the model are not straightforward either. But this does not negate the fact that both the model and its agentic mode with 4 competing agents show outstanding results (and pricetag:).

The context window size of 256k tokens is average by current standards. It handles confusing questions and planning very well. Judging by reviews, in practical programming tests it shows average results. It appeared in Cursor's list of available models, but not yet in Windsurf.

Unexpectedly, a bigger piece of news for programming was the appearance of a new open model from Moonshot AI. The model is not "thinking", but simply a Mixture-of-Experts (MoE). It can work as an agent because it knows how to use tools and functions.

The model can be connected via https://github.com/sst/opencode or any VSC plugins compatible with openrouter. It is also deployed on Groq.

Context window 131K. In tasks where planning is not needed, but simply code generation, the model outperforms Claude Sonnet 4. On openrouter there are different providers.
