signal brief
SpaceXAI has launched Grok 4.5, its first model since going public and acquiring Cursor. The model is priced at $2 per 1M input tokens and $6 per 1M output tokens, significantly cheaper than competing models like Anthropic's Opus 4.7 ($5/$25) and OpenAI's Sol ($5/$30) Axios. Bloomberg reports it is designed for legal, finance, and coding tasks Bloomberg. TechCrunch details that Elon Musk described it as an 'Opus-class model' with 'twice greater token efficiency' TechCrunch. Benchmark results show competitiveness just short of best-in-class. However, a lawsuit filed the same day alleges that a user generated 7,000 CSAM images using Grok, with xAI allegedly obstructing the investigation Ars Technica. This legal risk tempers the positive launch news. The low confidence reflects the juxtaposition of competitive product news and severe allegations.
