In a security-review bake-off, GPT-5.6 Sol caught every planted bug -- and no Anthropic model made the cost frontier News
A security firm tested 10 AI models on catching planted access-control bugs in pull requests and found GPT-5.6 Sol hit 100% recall at $0.70 per review, while no Anthropic model reached the cost-quality frontier for this specific task.
A researcher says xAI's coding tool uploads your whole repo -- secrets, unread files, and all News
An independent wire-level teardown found that xAI's Grok Build CLI uploads an entire code repository, including .env secrets and files the AI never read, to an xAI cloud bucket -- and the model-improvement opt-out does not stop it.
SpaceXAI ships Grok 4.5, trained on trillions of Cursor coding sessions News
SpaceXAI released Grok 4.5 on July 8, its first model as a public SpaceX subsidiary, trained on trillions of Cursor developer-interaction tokens and priced aggressively at $2 per million input tokens, though that rate only holds below 200K context.
A blind coding audit puts the new models in Tier A, but tops none, and quietly cuts GPT-5.5 by 11 points News
An independent blind-audited coding benchmark placed GPT-5.6 Sol (92) and Grok 4.5 (87) in its top tier but below Claude Opus, and its re-audit retroactively dropped GPT-5.5 from 96 to 85, exposing how unstable single-run model scores are.
Grok 4.5 arrives claiming Opus-class quality at a third the price News
SpaceXAI released Grok 4.5, a 1.5-trillion-parameter model priced at $2 per million input tokens and $6 per million output, undercutting frontier rivals roughly threefold while claiming comparable coding quality.
