Escalating Rivalry Among AI Enterprises as Competition Intensifies
The competitive landscape among artificial intelligence firms is becoming increasingly fervent as they vie for leadership in this rapidly evolving sector.
Anthropic has purportedly curtailed access to its models for xAI’s team, which had been utilizing them for coding purposes. In response, Nikita Bier, the head of product at X, indicated that there may be a potential ban on Anthropic’s access to the service.
“Hello team, many of you have likely observed that Anthropic models are currently unresponsive on Cursor. According to Cursor, this is a new policy being mandated by Anthropic for all significant competitors.” Tony Wu, co-founder of xAI, notified staff via Slack, following a report from Kylie Robinson of Core Memory.
“This presents a dual-edged scenario,” Wu elaborated. While we will experience a downturn in productivity, it catalyzes the urgency to cultivate our proprietary coding products and models.
We find ourselves at a juncture where AI has become a seminal technology for enhancing our productivity. The upcoming year promises to be exceptionally thrilling for all involved.
Our team is diligently working on developing our own models and product. We anticipate sharing updates soon. In the interim, feel free to explore diverse models through Grok Build, he urged.
It appears that xAI had been leveraging Anthropic’s models via Cursor for coding activities, and given their rival status, Anthropic’s decision to discontinue access is telling.
Elon Musk has previously lauded the quality of Anthropic’s models, remarking, “I must give @AnthropicAI credit here: Opus4.5 is outstanding,” in a post last month on X. Additionally, Google has been integrating Anthropic’s models for internal coding needs, with a Principal Engineer asserting last week that Claude Code accomplished more in a single instance than their team managed over an entire year.
However, discontent is palpable among Musk’s associates regarding the prohibition on their teams from utilizing Anthropic’s models. “Time to ban Anthropic from X,” Bier declared via X in reaction to the news. As of this writing, Anthropic’s presence on X remains unaffected.
This incident is not an isolated occurrence; Anthropic previously restricted access to its models, notably severing ties with Windsurf last year amid concerns that the latter had been acquired by OpenAI.
This move was presumably aimed at safeguarding data concerning the application of its models.

Such interruptions may lead AI companies competing with Anthropic to rethink their reliance on its services, potentially accelerating the development of equally robust models within their own organizations.
Moreover, these developments serve as a robust endorsement of Anthropic’s coding capabilities—its models are evidently distinguished in terms of efficacy and utility, as evidenced by usage across leading firms such as Google and xAI.
