    X launches X Subscription bundling Cursor, Grok, and X Premium; third-party models cost extra

    SpaceXAI announced the launch of The X Subscription, bundling Cursor, Grok, Grok Bot, and X Premium into a single subscription with five tiers, from free to $200 per month, with the lowest paid tier at $8. Under the new plan, third-party models are no longer included in the subscription fee and are billed at each provider's standard API rates from the first request, paid via prepaid credits, including on the $100 and $200 tiers. Matt Palmer, in a developer experience role at SpaceXAI, said that if most usage is concentrated on third-party models, the new plan may be more expensive, and recommended checking usage before switching.

    Arena releases Alignment Index, GPT-6.1-Sol tops with 87.9 points

    Arena.ai launched the Arena Alignment Index, which measures the safety and alignment performance of agents in real-world use based on over 90,000 real agent sessions across 27 models. The index tracks three signals: Unauthorized Action (UA), False Attribution (FA), and Deceptive Completion (DC). The leaderboard shows OpenAI's GPT-6.1-Sol in first place with 87.9 points, followed by Anthropic's Claude-Opus-5.5 with 83.2 points, and SpaceXAI's Grok-4.7 in third with 82.7 points; OpenAI also had the lowest observed rates on the three signals, at 0.89%, 1.98%, and 2.34%, respectively. Arena said unauthorized actions are rare but can have serious consequences, that misalignment risk rises as conversations grow longer, and that it will gradually add more safety signals and models.
