Summary
The debate over AI wearables is heating up, with OpenAI exploring new device concepts (and poaching Apple leaders to do so), Meta doubling down on smart glasses, and others exploring other form factors. The discussion centers on whether the future belongs to ambient AI devices or whether a more proactive AI makes more sense.

| 0:39.5 | five minutes. |
| 0:40.6 | We kick off with a new model out of XAI, which is called GROC4 Fast. |
| 0:46.0 | According to XAI, the model is capable of delivering similar results to GROC4 while using |
| 0:50.3 | 40% fewer reasoning tokens. |
| 0:52.8 | Combined with a big drop in cost per token and XAI says this results in a 98% reduction |
| 0:57.1 | in price to achieve the same performance on frontier benchmarks as GROC 4. |
| 1:01.7 | For example, on the AIME 2024 and 2025 math benchmarks, GROC 4 FASC achieves very similar |
| 1:07.0 | results to GROC 4 while using around 60% as many tokens. |
| 1:10.6 | Meanwhile, the model's performance on the GPQA Diamond Scientific Knowledge benchmark was slightly worse than GROC 4 while using around 60% as many tokens. Meanwhile, the model's performance |
| 1:11.6 | on the GPQA Diamond Scientific Knowledge benchmark was slightly worse than GROC 4, but matched GPT5 high. |
| 1:17.6 | Artificial analysis ran their independent benchmarking and came up with equally impressive results. |
| 1:21.7 | The model scored a 60 on their intelligence index, placing it in line with Gemini 2.5 Pro and |
| 1:26.3 | Claude 4.1 Opus, but slightly |
| 1:28.3 | below O3 or GpT5 high. Alongside the efficiency characteristics, Grock4Fast also features a 2 million |
| 1:34.3 | token context window, which is clearly aimed at things like large coding tasks. The model also |
| 1:39.1 | has a unified architecture, allowing both reasoning and non-reasoning variants to operate based |
| 1:43.3 | on the same model weights. |
| 1:44.6 | The operation of reasoning is controlled via system prompt rather than being baked into the model. |
