Day 0 Experience Frontier-Reasoning with NVIDIA Nemotron 3 Ultra on Bitdeer AI Model Studio
As autonomous agents take on increasingly complex, long-running tasks, from orchestrating multi-week coding projects to synthesizing hundreds of research sources in real time, the demands placed on the underlying reasoning model have fundamentally changed. Speed, depth of reasoning, and the ability to sustain context across extended sessions are no longer optional. They are the baseline for any model serious about agentic work.
Today, we are delighted to announce that NVIDIA Nemotron™ 3 Ultra is available at launch on Bitdeer AI Model Studio. As the flagship of the NVIDIA Nemotron family, Nemotron 3 Ultra is an open frontier reasoning model purpose-built or long-running autonomous agents. Designed to be smaller, faster, and lower cost for agent workflows, it delivers up to 5x faster inference and up to 30% lower cost while maintaining frontier-level reasoning capabilities for coding, deep research, and enterprise automation.
What is NVIDIA Nemotron 3 Ultra?
NVIDIA Nemotron 3 Ultra is an open frontier-reasoning model built for long-running autonomous agents. It is optimized for agent orchestration, complex reasoning, coding, and deep research workloads where speed, cost efficiency, and sustained reasoning depth matter as much as raw intelligence. Unlike traditional chat-focused models Nemotron 3 Ultra is designed for workflows that span hundreds of turns, multiple tools, and extended executive cycles—delivering up to 5x faster inference and up to 30% lower cost for agentic workloads
Post-trained for agent harnesses, Nemotron 3 Ultra sustains reasoning depth across the hardest calls — architectural decisions across week-long autonomous coding sessions, synthesis across hundreds of contradictory research sources, or verification of chip designs across thousands of interdependent constraints.
Fully open, Nemotron 3 Ultra can be fine-tuned for any domain and deployed on any infrastructure, giving enterprises the flexibility to maintain data control while benefiting from frontier-class intelligence.

Why Faster and Lower-Cost Agent Reasoning Matters?
Most production agentic systems are not bottlenecked by a single model call — they are bottlenecked by the cumulative cost of many. A coding agent planning a complex refactor, a research agent cross-referencing hundreds of sources, or an enterprise agent triaging thousands of alerts all depend on how quickly the model can complete each reasoning cycle. Throughput is not just a hardware metric; it is a direct multiplier on how much an agent can accomplish within any given time budget.
Nemotron 3 Ultra addresses this at the architectural level:
Fastest Task Completion. Ultra's Hybrid Mamba-Transformer MoE architecture delivers the highest token throughput in NVIDIA’s published comparisons against leading open frontier baselines, enabling more reasoning cycles per time budget. Multi-Token Prediction (MTP) further reduces generation time for long sequences by predicting multiple future tokens in a single forward pass, and NVFP4 precision, optimized specifically for NVIDIA Blackwell GPUs, delivers significant inference speedup versus FP8 while maintaining accuracy.
Leading Accuracy. Latent MoE enables Ultra to call four experts for the inference cost of just one, improving intelligence and generalization with no added compute cost. Multi-environment reinforcement learning training across a broad set of agentic environments gives the model robust tool calling, reasoning, and instruction-following capabilities. The 1M token context window retains conversation history and plan states across long-running agent sessions, and enables cross-document reasoning at a scale that shorter-context models cannot match.
Fully Open. Ultra is released with open weights under NVIDIA's open-model license, trained on NVIDIA-generated high-quality synthetic data that is fully open, and accompanied by published development techniques and recipes, giving researchers and enterprises full transparency and the flexibility to customize or build on top of the model.
Enterprise Use Cases

Source: NVIDIA
Programming and Coding Agents. Coding agents built on Ultra plan, code, test, debug, and iterate end-to-end across large codebases. Ultra handles the hard reasoning calls: architectural planning, complex multi-file refactors, and error recovery, sustaining coherent reasoning across sessions that can span days or weeks.
Deep Research and Search. Research agents search, evaluate, cross-reference, and synthesize across hundreds of sources in sustained parallel loops. Ultra handles final synthesis, the step where contradictions must be resolved, gaps must be identified, and novel hypotheses proposed with the depth and consistency that frontier reasoning demands.
Enterprise Workflow Agents. Agents built for enterprise workflows automate operations across industries in persistent, tool-using loops: triaging thousands of security alerts, ingesting and interpreting regulatory filings, orchestrating clinical trial operations. Ultra handles the complex reasoning steps within these workflows, where errors in judgment have real downstream consequences.
EDA and Chip Design. Chip design agents autonomously generate RTL from specifications, verify designs across thousands of constraints, and orchestrate workflows from design to manufacturing sign-off. Ultra handles verification, failure analysis, and cross-block dependency resolution — the reasoning-intensive operations that define the quality of the final design.
Supported Agentic Frameworks
Nemotron 3 Ultra integrates with leading open agent frameworks out of the box — from single-command deployment with NVIDIA NemoClaw to tested cookbooks for the most popular coding and orchestration platforms. It is also packaged as an NVIDIA NIM microservice, making it deployable across data center and cloud environments without modification.
