Grok 4.5 Launched: Elon Musk's AI Challenges Rivals

Elon Musk’s xAI has launched Grok 4.5, intensifying the AI arms race. This new model promises faster and cheaper coding assistance. Developers are already building complex projects more quickly, leading Musk to invite more users to try it. Grok 4.5 aims to undercut competitors on price while matching or beating their performance. xAI calls it an "Opus-class" model, directly challenging Anthropic's Claude Opus line. It claims to use 4.2 times fewer output tokens than Anthropic’s Opus 4.8 on specific coding benchmarks. The model is priced at $2 per million input tokens and $6 per million output tokens. It features a 500k-token context window and runs on tens of thousands of NVIDIA GB300 GPUs. What's interesting is how this impacts crypto-adjacent compute markets. The efficiency of Grok 4.5 could pressure revenue models for decentralized compute networks if it genuinely reduces the compute needed per task. This launch positions xAI as a significant threat to other major AI players.
