Nace AI发布Drex 1.5决策模型
Nace AI出了个128k上下文的决策模型Drex 1.5，比Jev便宜还得分更高，首批开发者能获250M免费token。
Nace AI推出Drex 1.5，这是首个拥有128k上下文窗口的决策模型。该模型参数量不足10B，每100万输入token收费0.04美元，在决策指数0.2.1基准上得分为58.28，超过Jev 1.13.0的57.91。用户可发送完整合同或视频转录内容获取评分决策，无需处理分块或拼接结果。
Nace AI just released Drex 1.5 — the first (and so far the only) decision model with a 128k context window.
128k is really good! You can send an entire contract or a video transcript and get a scored decision over the whole thing. You don't need to mess with chunking or stitching results back together.
The idea is the same as with Jev:
• Input: context + a set of choices • Output: classification + score for every option
For example, you can use Drex to classify a review as "POSITIVE", "NEGATIVE", or "NEUTRAL", and route any low-scored answer to a human for further inspection.
Here is where the model differs from Jev:
• 128k context • Small - It's under 10B parameters • $0.04 per 1M input tokens, a bit cheaper than Jev
The model is #1 on the Decision Index 0.2.1 (chance-corrected; random guessing = 0):
• Drex: 58.28 • Jev 1.13.0: 57.91
Nace is giving 250M free tokens to the first 10,000 builders: https://t.co/Q2j9qu28KY
