Fireworks AI vs Skild AI
Side-by-side comparison of AI visibility scores, market position, and capabilities
Fireworks AI (ex-Meta PyTorch) reached ~$315M ARR at $4B valuation, serving 10K+ customers at 10T+ tokens/day on $327M raised; fastest open-model inference.
About
Fireworks AI is a high-performance AI inference platform founded in San Francisco by veterans of Meta's PyTorch team. The company was built to solve a critical gap in the AI infrastructure market: making large language model inference fast enough, cheap enough, and reliable enough for production-scale applications. Fireworks AI's founding team brings direct experience building the open-source deep learning framework that underlies much of the industry's AI work.\n\nThe platform offers access to a broad model library — including open-source models like Llama and Mixtral, as well as Fireworks' own optimized variants — served through a high-throughput API optimized for low latency and high concurrency. Key differentiators include custom model fine-tuning and serving, function calling, and structured output generation, along with pricing that can be dramatically lower than hyperscaler alternatives for high-volume workloads. Customers range from AI-native startups building inference-heavy products to enterprises migrating workloads from OpenAI or Anthropic to open models.\n\nFireworks AI has achieved approximately $315 million in annualized recurring revenue and processes over 10 trillion tokens per day — metrics that place it among the leading independent AI inference providers. The company reached a $4 billion valuation after raising $327 million in total funding. With 10,000+ customers, Fireworks AI is benefiting from the rapid growth of open-weight model adoption as organizations seek to reduce AI infrastructure costs while maintaining performance.
Universal robot brain startup raised $1.4B Series C at $14B valuation in Jan 2026 led by SoftBank with Nvidia and Bezos; $30M 2025 revenue; deployed at Foxconn
About
Skild AI is building a universal robot brain — a foundation model for physical intelligence that can power a broad range of robot types without requiring task-specific training for each deployment. Founded to solve the fragmentation problem in robotics AI, where every robot type and task requires separate model development, Skild's approach trains a single generalist model on diverse robotic data and fine-tunes it rapidly for specific deployments. The company was founded by robotics AI researchers who identified the model reuse gap as the primary barrier to scalable robot deployment.\n\nSkild's generalist robot model has been deployed across more than 30 distinct robot types — spanning manipulation arms, mobile platforms, and humanoid form factors — demonstrating the cross-hardware generalization that most robot AI systems lack. The platform targets robotics manufacturers, logistics operators, and industrial automation companies that need AI-capable robots but lack the internal ML infrastructure to develop foundation models themselves. By offering a model-as-a-service layer, Skild enables robot OEMs and systems integrators to add AI capabilities without building the underlying research infrastructure.\n\nSkild AI raised a $1.4 billion Series C in January 2026 at a $14 billion valuation, led by SoftBank with co-investment from NVIDIA and Jeff Bezos. The round was one of the largest in robotics AI history and reflects institutional conviction in the physical AI market's scale. With $30 million in 2025 revenue and accelerating enterprise deployments, Skild is building the financial foundation to match its valuation. The SoftBank-NVIDIA investor combination positions Skild at the center of the global robotics deployment wave.
