IFA 2026 memory

AMD launches Ryzen AI Max PRO 400 with 192GB unified memory - up to 160GB addressable as VRAM

At its IFA 2026 opening keynote AMD commercially launched the Ryzen AI Max PRO 400 series, whose single LPDDR5X-8533 pool of up to 192GB (around 273 GB/s) lets the integrated Radeon 8060S iGPU map up to 160GB as VRAM - on paper enough to hold quantized 300B-parameter models on a desk with no discrete GPU and no cloud. Commercial systems from HP and Lenovo are targeted for Q3 2026; the 192GB SKU's tight SK Hynix LPDDR5X supply remains the open question.

NVIDIA: new llama.cpp and vLLM optimizations lift local LLM throughput up to 1.9x on RTX 5090, RTX PRO 6000 and DGX Spark

New XQA attention kernels in FlashInfer deliver up to 1.9x throughput (Qwen3.6-35B on an RTX 5090), with 1.2x on RTX PRO 6000 Blackwell and 1.4x on a dual DGX Spark cluster; the gains reach users through llama.cpp, vLLM, LM Studio and Ollama.

Why Gated DeltaNet survives 4-bit quantization: NVFP4 W4A4 for the recurrent half of a hybrid 27B LLM

Quantizes all 496 Gated DeltaNet layers of the hybrid 27B Qwen3.8-27B to NVFP4 W4A4, including the decay and write-strength gates previously kept at 8/16-bit, and matches BF16 within seed noise across perplexity, MMLU-Pro, GSM8K, AIME'25, GPQA-Diamond and RULER to 64K tokens - disproving the community intuition that recurrent-state errors accumulate fatally under low precision.

Random attention: scored token selection adds almost nothing to KV cache eviction

Salesforce AI Research shows that evicting uniformly at random per attention head, while keeping the prompt, matches the strongest prior evictor across four models and six reasoning tasks while serving 32-43% higher throughput in vLLM deployment.

Rethinking on-policy distillation II: one training example is enough to go far

On-policy distillation on a single query keeps improving for hundreds of steps and recovers most of full-data OPD's gain across task domains and model families, making distillation feasible at the data-minimal limit.

Hardware-aware FP4 FlashAttention-4 maps attention scores straight to FP4 probabilities

Reaches up to 2.13x the BF16 forward throughput on an NVIDIA GB200 (Blackwell) by feeding the forward quantization directly into the backward pass with FP8 gradient operators, addressing the finding that FP4 tensor cores alone do not speed up attention once softmax conversion dominates.

VestigeKV: the NoPE-MLA KV cache carries its own eviction signal in a vestigial branch

On Kimi Linear, attention-observed selectors like H2O and SnapKV collapse on needle retrieval; VestigeKV evicts using the query-independent signal already present in the 64-dimensional decoupled RoPE branch, reading 11% of each row to partition the cache before future queries exist.

Unlocking lossless speedups in LLMs via discrete diffusion

Diffusion-augmented LLMs keep the autoregressive distribution but use lightweight diffusion weights to draw multiple tokens in parallel from it, targeting the sequential-generation bottleneck with lossless decoding speedups.

IFM releases K2 Horizon: six fully open models (0.9B-375B) with weights, code and training data

The Institute of Foundation Models opens everything - weights, code, training data, recipes and evaluations - across a fleet from 0.9B to 375B, with diffusion distillation for roughly 3x faster inference and a Mixture-of-Value-Attention 36B-A4B model that reportedly beats MoE models up to 15x its size; the 36B-A4B GGUF checkpoints landed on the Hub yesterday.

Free means $0 per token today, not unlimited or unconditional: both platforms rate-limit free use and require a free API key, some OpenRouter free endpoints may train on your prompts unless you opt out in account settings, and the roster changes daily. Verified against each provider's own pricing data at generation time — but pricing changes without notice, so confirm it's still free on the provider's own page before you rely on it.
