OpenAI Unveils Jalapeño AI Chip; Callstack Acquires Margelo for €20M
OpenAI is set to introduce its first proprietary AI chip, "Jalapeño," designed specifically for inference workloads in collaboration with Broadcom. The chip aims to challenge Nvidia's dominance in the inference market by offering superior performance-per-watt metrics compared to Nvidia's Blackwell GPUs. Simultaneously, Polish cross-platform software specialist Callstack has announced the acquisition of Vienna-based React Native engineering firm Margelo in a transaction valuing Margelo at over €20 million. Backed by a €120 million growth investment from Viking Global Investors in 2025, Callstack plans to utilize Margelo's highly popular open-source libraries and advanced architecture capabilities to address the shifting demands of AI-accelerated software development.
OpenAI entering the custom physical AI silicon space with Broadcom directly challenges Nvidia's infrastructure monopoly and will alter operational economics for major AI platforms.

OpenAI and Broadcom Reveal Jalapeño AI Chip
OpenAI and Broadcom publicly unveiled Jalapeño, their first jointly developed custom AI inference accelerator, positioning it as an “Intelligence Processor” designed to improve performance‑per‑watt and lower token costs for large language model inference. Broadcom has already delivered engineering silicon to OpenAI; Broadcom CEO Hock Tan expects initial deployment late 2026, a ramp in 2027 and full-scale deployment in 2028. The announcement arrives as Broadcom shares have fallen sharply since early June, and follows market reports that hyperscalers (Alphabet, ByteDance) are exploring additional chip design partners to diversify supply. OpenAI’s Greg Brockman emphasized Jalapeño is complementary to, not a replacement for, GPU-based solutions from firms like Nvidia. The collaboration signals increased vertical integration by an AI provider and a potential pathway to reduce inference costs and diversify compute beyond dominant GPU suppliers.
OpenAI unveils Jalapeño inference chip with Broadcom
OpenAI unveiled its first custom-built inference processor, called Jalapeño, developed in collaboration with Broadcom. The chip is designed specifically for inference workloads and, according to OpenAI, early tests show substantially better performance-per-watt than current alternatives. OpenAI said its own AI models assisted chip development. The partnership with Broadcom was announced previously in October, and the move is widely seen as a way for OpenAI to reduce reliance on Nvidia GPUs for inference, while heavier tasks like pre‑training will likely continue to use existing GPU hardware. OpenAI framed the chip as part of a broader strategy to optimize across the stack — from chip architecture to deployment systems — to make models faster, more reliable, and cheaper to run.
OpenAI and Broadcom unveil Jalapeño inference chip
OpenAI and Broadcom announced Jalapeño, an LLM-optimized accelerator described as OpenAI’s first 'Intelligence Processor' and the initial component of a multi-generation compute platform co-developed with Broadcom and Celestica. OpenAI says the chip was designed from the ground up for modern and future LLM inference, produced from design to tape-out in nine months with assistance from OpenAI models, and that engineering samples are running ML workloads (including GPT‑5.3‑Codex‑Spark). Early internal testing reportedly shows performance per watt substantially better than current state-of-the-art; a detailed technical report will follow. The partners plan gigawatt-scale deployments with data center partners (including Microsoft) beginning in 2026, aiming to lower inference cost, latency, and improve reliability for large-scale interactive LLM products.
