   Maia 300 goes inference-only as hyperscalers split training, inference chips

   An analysis piece republished by Huxiu (originally from the outlet 偏科声) says Microsoft's Maia 300 drops the redundant training-oriented hardware of earlier designs to focus on high-concurrency inference: long-context chat, low-latency interaction and multi-step agent workloads. It traces the arc from the November 2023 Maia 100, a combined training/inference architecture, to this January's Maia 200, which already tilted its architecture and scheduling toward inference. The article groups the move with Google's eighth-generation TPU lineup, where TPU 8i targets inference, and Amazon's separate Trainium (training) and Inferentia (inference) lines, framing it as hyperscalers sidestepping Nvidia's CUDA training ecosystem for lower-barrier, faster-payback commercial inference. It cites Microsoft's technical team as estimating a 30%–50% cut in per-token inference cost at scale, and IDC and Inspur projections that inference could exceed 70% of AI compute by 2026 — figures the article relays from vendors and research firms without independent verification.

   Infinigence AI closes RMB 2.3B C round ahead of confidential Hong Kong IPO filing

   Infinigence AI, a Chinese AI compute-scheduling company, has completed a RMB 2.3 billion Series C round, bringing total funding to roughly RMB 4.3 billion, according to a report republished by Cyzone and originally from Guangzhui Tech. Citing unnamed sources and Bloomberg, the report says the company filed confidentially with the Hong Kong Stock Exchange in early October to raise several hundred million dollars, with CITIC Securities, Haitong International and UBS as sponsors and a listing possibly as early as the first half of 2027; the IPO details have not been confirmed by the company. Infinigence does not make chips or own data centers, saying it manages more than 37,000 P of compute across 16 mainstream chip types, and at WAIC it reframed its business from selling raw compute to selling tokens through a "front store, back factory, one center" model. Rival SiliconFlow, which filed in Hong Kong in June, reported 2025 revenue of RMB 55.33 million (up 653%) alongside a widening net loss of RMB 345 million and gross margin falling from 39.4% to -24%, underscoring the profitability challenge for such intermediaries.

   StepFun opens Step 5 Preview weights: 600B MoE, 1M-token context

   StepFun released the open weights of its flagship Step 5 Preview model on October 15, publishing BF16 and FP8 versions on Hugging Face and ModelScope alongside a technical blog and deployment guide. The model is a sparse Mixture-of-Experts system with 600B total parameters, 27B active per token and up to a 1M-token context window, positioned for long-horizon agentic work in software engineering, professional knowledge work and finance; its model card also lists text, image and video input, while several reports describe native text and vision only. IT之家 reported that Huawei Ascend, Biren, MetaX and Moore Threads announced day-zero support, with Huawei saying its first 1,024-card Atlas 950 SuperPoD liquid-cooled cluster came online alongside the release. Zhidx, citing Artificial Analysis, said Step 5 Preview scored 44 on the Intelligence Index for a top-three open-model placement, and citing OpenRouter data said it ranked second globally on both the weekly and daily token-usage charts as of October 15.
