Microsoft Releases Third-Generation In-House AI Chip Maia 300, Entering Production in 2027

On October 12, 2026, The Verge reported that Microsoft released its third-generation in-house AI chip, Maia 300, positioned as the "primary AI inference system" for Microsoft's products and services, aimed at reducing reliance on Nvidia GPUs. Microsoft plans to begin producing Maia 300 in 2027 and to expand the Azure Maia family to multi-gigawatt deployments starting in 2027. Later the same day, The Decoder reported that Microsoft announced it would deploy Azure Maia AI chips at multi-gigawatt scale from 2027, with Microsoft executive Scott Guthrie saying it would become the primary inference system for Microsoft's products. The two reports are largely consistent on timing (production and deployment from 2027) and positioning (primary AI inference system), but The Decoder's wording refers to the Azure Maia chip family as a whole, while the earlier report said Maia 300 is the primary inference system, and the later report attributes that claim to executive Scott Guthrie. Only these two reports exist so far, with no further developments available.
