Unlike previous approaches that rely on imitating reasoning trajectories from stronger models, Tool-N1 uses a binary RL reward system that only evaluates the format validity and functional correctness of tool invocations, without supervising the intermediate reasoning process.\nThe research demonstrates that Tool-N1-7B/14B models outperform GPT-4o on several major benchmarks. Through a systematic study using 5,518 distilled reasoning trajectories, the authors compare SFT, RL, and combined SFT-then-RL pipelines, finding that pure RL can be more effective than the widely adopted SFT-then-RL approach for tool-calling tasks. This challenges conventional wisdom about the necessity of supervised pre-training before reinforcement learning.\nThe approach offers several advantages over traditional methods: it provides interpretable supervision signals through rule-based reward design; it enables more flexible training by not enforcing strict output matching; and it allows models to develop their own reasoning strategies independently without relying on annotated trajectories. This work contributes to advancing tool-using language models by demonstrating how reinforcement learning can be effectively applied to develop stronger reasoning capabilities in tool-calling scenarios.\n<<< Podcast outline >>>\n# Podcast Outline: \"AI Breakthroughs: Reinforcement Learning for Tool-Calling Models\"\n## Introduction (30 seconds)\n- **Adam**: Welcomes listeners to the

They explore how this approach achieves superior performance with smaller models and what it means for the future of AI development.\", \"lines\": [\n{\"text\": \"Welcome to 'Tech Horizons,' where we explore the cutting edge of artificial intelligence. I'm your host, Adam. Today, we're diving into a fascinating breakthrough in tool-calling AI models. Joining me is Bella, an AI researcher specializing in language models and part of the team behind the Nemotron-Research-Tool-N1 paper. Bella, thanks for being here!\", \"speaker\": \"Adam\"},\n{\"text\": \"Thanks for having me, Adam. Excited to chat about our work on Tool-N1.\", \"speaker\": \"Bella\"},\n{\"text\": \"So let's start with the basics. What exactly is Tool-N1, and how does it differ from previous models in this space?\", \"speaker\": \"Adam\"},\n{\"text\": \"Tool-N1 is essentially a series of language models specifically designed for tool-calling capabilities. The key innovation here is our approach to training. While most models in this space rely on supervised fine-tuning, where they essentially imitate reasoning trajectories from stronger models, we took a different path using reinforcement learning or RL. We've developed versions in both 7 billion and 14 billion parameter sizes.\", \"speaker\": \"Bella\"},\n{\"text\": \"For our listeners who might not be familiar, could you explain what 'tool-calling' actually means in the context of AI, and why it matters?\", \"speaker\": \"Adam\"},\n{\"text\": \"Sure thing. Tool-calling is an AI's ability to recognize when it needs external capabilities and then correctly invoke them. Think of an AI that knows when to use a calculator, search an API, or access a database. It's crucial because it extends what AI can do beyond its training data, making it much more useful in real-world applications.\", \"speaker\": \"Bella\"},\n{\"text\": \"That makes sense. Now, you mentioned using reinforcement learning rather than supervised fine-tuning. Could you break down the traditional approach versus what you did with Tool-N1?\", \"speaker\": \"Adam\"},\n{\"text\": \"Traditionally, we'd train a model by showing it examples of correct reasoning trajectories from stronger models – essentially saying 'copy this expert.' With Tool-N1, we implemented a binary reward system that only evaluates two things: is the format valid, and is the function call correct? We don't supervise any of the intermediate reasoning steps. The model figures those out entirely on its own.\", \"speaker\": \"Bella\"},\n{\"text\": \"Wait, so you're not telling the model how to think through the problem? That seems counterintuitive. I would have thought you'd want to guide its reasoning process.\", \"speaker\": \"Adam\"},\n{\"text\": \"That's exactly what makes this interesting! The conventional wisdom has always been that you need to guide models through complex reasoning. Our research shows that with the right reward structure, the model can develop its own effective reasoning strategies. It's like teaching a child by only telling them if the final answer is right, not how to solve the problem.\", \"speaker\": \"Bella\"},\n{\"text\": \"That's fascinating. So how does Tool-N1 perform compared to industry standards like GPT-4?\", \"speaker\": \"Adam\"},\n{\"text\": \"The results actually surprised us. Both our Tool-N1-7B and 14B models outperform GPT-4o on several major benchmarks. That's remarkable considering our models are much smaller. The 7B model has less than 1% of the parameters that GPT-4 likely has, yet it still outperforms it on tool-calling tasks.\", \"speaker\": \"Bella\"},\n{\"text\": \"Which benchmarks were most impressive?\", \"speaker\": \"Adam\"},\n{\"text\": \"We tested across a range of tool-based reasoning tasks. What's particularly exciting is our performance on complex multi-step reasoning problems where the model needs to chain several tool calls together to reach a solution. These are precisely the kinds of tasks where you'd expect supervised fine-tuning to be necessary.\", \"speaker\": \"Bella\"},\n{\"text\": \"You know, there's been this standard pipeline in AI development where you do supervised fine-tuning first, then apply reinforcement learning. But your paper seems to challenge that approach?\", \"speaker\": \"Adam\"},\n{\"text\": \"Absolutely. We systematically analyzed 5,518 distilled reasoning trajectories comparing SFT, RL, and combined SFT-then-RL pipelines. What we found is that pure RL can actually be more effective than the standard SFT-then-RL pipeline for tool-calling tasks. This really does challenge the conventional wisdom that you need supervised pre-training before applying reinforcement learning.\", \"speaker\": \"Bella\"},\n{\"text\": \"That could have huge implications for how AI systems are developed. What would you say are the practical advantages of your approach?\", \"speaker\": \"Adam\"},\n{\"text\": \"There are three key advantages. First, we get interpretable supervision through rule-based reward design – we know exactly what we're reinforcing. Second, the training is more flexible since we're not enforcing strict output matching. And third, models develop independent reasoning strategies rather than just imitating larger models. This could lead to more diverse and potentially more innovative AI systems.\", \"speaker\": \"Bella\"},\n{\"text\": \"And potentially more cost-effective development, right? If smaller models can perform at this level without the complex supervised fine-tuning step?\", \"speaker\": \"Adam\"},\n{\"text\": \"That's a great point. The computational resources needed for traditional supervised approaches can be enormous. Our method potentially offers a more efficient path to developing highly capable AI systems, which could democratize access to this technology.\", \"speaker\": \"Bella\"},\n{\"text\": \"As we wrap up, what do you see as the future implications of this work for AI tool-using capabilities?\", \"speaker\": \"Adam\"},\n{\"text\": \"I think we're just scratching the surface. This approach could extend beyond tool-calling to other capabilities requiring complex reasoning. It suggests we might need to rethink some fundamental assumptions about how to train AI systems. Rather than more supervision, sometimes the right incentive structure might be all you need for AI to develop sophisticated capabilities.\", \"speaker\": \"Bella\"},\n{\"text\": \"Fascinating stuff. Thank you, Bella, for sharing these insights on Tool-N1. To our listeners, this conversation highlights how reinforcement learning alone might be more powerful than we thought for developing sophisticated AI capabilities. It's another reminder of how quickly this field is evolving. Thanks for tuning in to 'Tech Horizons,' and we'll catch you next time.\", \"speaker\": \"Adam\"}\nffmpeg version 5.1.6-0+deb12u1 Copyright (c) 2000-2024 the FFmpeg developers\nbuilt with gcc 12 (Debian 12.2.0-14)\nconfiguration: --prefix=/usr --extra-version=0+deb12u1 --toolchain=hardened --libdir=/usr/lib/x86_64-linux-gnu --incdir=/usr/include/x86_64-linux-gnu --arch=amd64 --enable-gpl --disable-stripping --enable-gnutls --enable-ladspa --enable-libaom --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libcodec2 --enable-libdav1d --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libglslang --enable-libgme --enable-libgsm --enable-libjack --enable-libmp3lame --enable-libmysofa --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-libpulse --enable-librabbitmq --enable-librist --enable-librubberband --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libsrt --enable-libssh --enable-libsvtav1 --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvorbis --enable-libvpx --enable-libwebp --enable-libx265 --enable-libxml2 --enable-libxvid --enable-libzimg --enable-libzmq --enable-libzvbi --enable-lv2 --enable-omx --enable-openal --enable-opencl --enable-opengl --enable-sdl2 --disable-sndio --enable-libjxl --enable-pocketsphinx --enable-librsvg --enable-libmfx --enable-libdc1394 --enable-libdrm --enable-libiec61883 --enable-chromaprint --enable-frei0r --enable-libx264 --enable-libplacebo --enable-librav1e --enable-shared\nlibavutil 57. 28.100 / 57. 28.100\nlibavcodec 59. 37.100 / 59. 37.100\nlibavformat 59. 27.100 / 59. 27.100\nlibavdevice 59. 7.100 / 59. 7.100\nlibavfilter 8. 44.100 / 8. 44.100\nlibswscale 6. 7.100 / 6. 7.100\nlibswresample 4. 7.100 / 4. 7.100\nlibpostproc 56. 6.100 / 56. 6.100\n[mp3 @ 0x56977b85fe00] Estimating duration from bitrate, this may be inaccurate\nInput #0, concat, from '/tmp/file_list.txt':\n Duration: N/A, start: 0.000000, bitrate: 128 kb/s\n Stream #0:0: Audio: mp3, 32000 Hz, mono, fltp, 128 kb/s\nOutput #0, mp3, to 'podcast.mp3':\nMetadata:\n TSSE : Lavf59.27.100\n Stream #0:0: Audio: mp3, 32000 Hz, mono, fltp, 128 kb/s\nStream mapping:\n Stream #0:0 -> #0:0 (copy)\nPress [q] to stop, [?] for help\nsize= 1kB time=00:00:00.03 bitrate= 266.0kbits/s speed=N/A\n[mp3 @ 0x56977b879500] Estimating duration from bitrate, this may be inaccurate\n[mp3 @ 0x56977b8824c0] Estimating duration from bitrate, this may be inaccurate\n[mp3 @ 0x56977b875940] Estimating duration from bitrate, this may be inaccurate\n[mp3 @ 0x56977b86ae80] Estimating duration from bitrate, this may be inaccurate\n[mp3 @ 0x56977b864240] Estimating duration from bitrate, this may be inaccurate\n[mp3 @ 0x56977b863880] Estimating duration from bitrate, this may be inaccurate\n[mp3 @ 0x56977b8a6c80] Estimating duration from bitrate, this may be inaccurate\nLast message repeated 2 times\n[mp3 @ 0x56977b863880] Estimating duration from bitrate, this may be inaccurate\nsize= 6711kB time=00:07:09.48 bitrate= 128.0kbits/s speed=7.94e+03x\nvideo:0kB audio:6711kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.009037%\n]}",
