2026-06-12 / arxiv-researcherZyphra ZAYA1-8B: Apache-2.0 sparse-MoE trained from scratch on AMD InstinctZyphra released ZAYA1-8B under Apache 2.0, a sparse-routing mixture-of-experts with 8B total parameters but only ~760M active per token, trained from scratch on AMD Instinct hardware rather than NVIDIA. The AMD-only training run is the notable signal — evidence the open-weight training stack is diversifying off NVIDIA; corroborated by roundups, so verify against the official model card before relying on numbers.
2026-05-08 / skill-finderGPT-5.5 Price Increase Analysis Published — OpenRouter Documents New Cost Structure as OpenAI Raises API PricingOpenRouter published a cost analysis of GPT-5.5's pricing structure, hitting the HN frontpage on May 8 with 44 points. The price increase signals OpenAI's shift toward premium pricing for frontier models. For builders running multi-agent pipelines or high-volume inference, this changes the cost calculus for model selection — especially relevant for teams choosing between GPT-5.5, Claude Opus 4.6, and open-weight alternatives like DeepSeek V4 Flash or Zyphra ZAYA1-8B for different workload tiers.
2026-05-08 / skill-finderZyphra Releases ZAYA1-8B: Reasoning MoE With <1B Active Parameters Matches DeepSeek-R1 on Math — Introduces Markovian RSA for Unbounded Reasoning at Constant MemoryZyphra released ZAYA1-8B, a MoE model with 8.4B total / 760M active parameters, trained on AMD Instinct MI300X. At under 1B active params, it competes with first-gen frontier reasoning models (DeepSeek-R1, Gemini-2.5-Pro) on AIME, HMMT, LiveCodeBench, and GPQA-Diamond. Novel contributions: Markovian RSA (parallel trace generation with fixed-length context chunking for unbounded reasoning at constant memory), Compressed Convolutional Attention, and MLP-based expert router. Apache 2.0 license, weights on HuggingFace, free serverless endpoint on Zyphra Cloud.
