𝗝𝗲𝗳𝗳 𝟭.𝟭 𝗶𝘀 𝗼𝘂𝘁! 🚀 Our open-source Jeff decision models just got a lot better. Jeff-1.1-Large on OpenDecisions: 89.0 in one pass 92.3 with optional reasoning (Jeff-1.0-Large: 84.9, Jev: 80.1) What changed? 🧵👇

Some things that were useful when my agent and I were building the data for this model: - Check how well you can guess the answer from the options alone. One source looked like a +4.5 gain, but it was mostly "the longest option is right". Real gain was more like +2.3 - Weight

Everyone is talking about 'System One models' like Jev: given a state, question, and set of options, they return a calibrated decision at a fraction of the cost of an LLM call. But do we need specialized architectures and recipes to train them? We show you don’t: 🧵👇

Here's what happens to speculative decoding when the prompt gets long. @GoogleAI @googlegemma Gemma 4 26B on one RTX 3090, 28k-token prompt: DFlash: 0.66x. Slower than not speculating at all. Uno: 1.30x. Still pulling ahead. That's 2x DFlash. Lossless. Same card, same model,
