A competition among ai coding agents has led to a price war, with grok 4.5 launching with aggressive pricing that undercuts some of its competitors. The pricing of grok 4.5 is said to be significantly lower than that of anthropic and openai, although the exact details of the competition and the participants are not entirely clear. The situation is further complicated by the introduction of other ai coding agents, including gpt-5.6 and muse spark 1.1, which may also be part of the pricing competition.
