MemT-1.0: Towards Memory-Native Evolution Slashing 128K KV Footprint by 66x with Gated DeltaNet-2

Researchers introduced MemT-1.0 (arXiv:2610.26825), a groundbreaking architecture internalizing memory as an intrinsic component of foundation model computation. Moving beyond exploding KV caches and lossy Vector RAG pipelines, MemT-1.0 employs Gated DeltaNet-2 with stable within-turn token-level updates alongside a novel Mixture-of-Storage mechanism. Trained across a two-stage 34B-token pipeline, the released MemT-1.0-Nano model achieves a 1.86x end-to-end inference speedup and a staggering 66x reduction in persistent storage at 128K tokens relative to full-context KV caching, dramatically elevating procedural task execution in autonomous agents.

MemT-1.0: Towards Memory-Native Evolution Slashing 128K KV Footprint by 66x with Gated DeltaNet-2

Key Takeaways

  • MemT-1.0 introduced on arXiv:2610.26825, pioneering memory-native evolution by internalizing memory directly into model computation
  • Combines Gated DeltaNet-2 with stable token-level memory updates and Mixture-of-Storage to scale memory capacity intrinsically
  • At 128K context length, delivers a 1.86x inference speedup and slashes persistent storage by 66x compared to standard KV cache
  • Internalizes procedural operational experience, significantly improving agentic multi-turn task success rates

Inception Unveils Mercury 3: Diffusion-Based LLM Breaks 1,000+ Tok/s with 1M Context Window

Inception co-founder Stefano Ermon officially unveiled Mercury 3, the company's next-generation diffusion-based large language model. Delivering an astonishing 1,068 tokens per second inference speed on NVIDIA GPUs, Mercury 3 scales to 40x the size of Mercury 1 with a native 1M context window. Benchmarked on IFBench, GPQA Diamond, and SWE-Bench Atlas, it matches frontier closed baselines with standard API pricing of $0.20 / $0.70 per 1M input/output tokens (with 50% promotional pricing of $0.10 / $0.35).

Key Takeaways

  • Inception co-founder Stefano Ermon officially launched Mercury 3, a diffusion LLM generating 1,068 tokens per second on NVIDIA GPUs
  • Scales model size by 40x over Mercury 1 with a native 1M context window; priced at $0.20 / $0.70 per 1M tokens ($0.10/$0.35 promotional)
  • Triples baseline intelligence on IFBench, GPQA Diamond, and SWE-Bench Atlas, with live availability via OpenRouter
  • Bypasses autoregressive sequential bottlenecks via parallel diffusion denoising, accelerating multi-step agent workflows

Codex kicks off "28 days of improvements or a full reset": Day 1 makes GPT-6 Astra and GPT-6.1 Sol ~50% faster by default, including OpenCode, Pi, Amp and Devin via Sign in with ChatGPT

On Oct 5, Codex lead Thibault "Tibo" Sottiaux committed that for the next 28 days OpenAI will ship one clear improvement for most Codex/ChatGPT Work users each day, or give everyone a full usage reset. Day 1 is an inference speedup: GPT-6 Astra and GPT-6.1 Sol are ~50% faster by default on subscriptions (roughly 30 to 50 tokens/s), including partner tools using Sign in with ChatGPT. No API speed change was announced.

Key Takeaways

  • 28-day pledge: each day either one clear improvement or a full usage reset for everyone (OpenAI Developer Community thread)
  • Day 1: GPT-6 Astra / GPT-6.1 Sol default speed ~+50%; Tibo cited roughly 30 to 50 tokens/s (closer to +67% if exact; both called approximate)
  • Scope: OpenAI products plus every Sign in with ChatGPT partner (OpenCode, Pi, Amp, Devin), no config change, live within ~2 hours
  • Subscription path only; no API speed change announced, so API-billed evals are unaffected
  • One community user reported slower 6.1 Sol runs on a private benchmark after the change; unverified single data point

Continuous Depth Batching (CDB): Unlocking Depth-Adaptive Inference for Looped Language Models with 99% Speedup Realization

While looped language models enable depth-adaptive inference by executing fewer layer repetitions on easy tokens and more on complex tokens, variable loop counts break conventional batching engines like vLLM. Researchers from TUM and Imperial College introduced Continuous Depth Batching (CDB). By dynamically reorganizing batches between loop iterations, orchestrating looped KV-caches, and asynchronously predicting token exits, CDB achieves up to 99% of the theoretical maximum inference speedup across Ouro 1.4B and Huginn 3.5B architectures.

Continuous Depth Batching (CDB): Unlocking Depth-Adaptive Inference for Looped Language Models with 99% Speedup Realization

Key Takeaways

  • Resolving the Looped Batching Impasse: Depth-adaptive inference allows tokens to exit recurrent transformer layers early, but differing loop counts prevent uniform forward passes in engines like vLLM; CDB introduces inter-step batch reformation.
  • Asynchronous Exit Prediction & Looped KV Cache: Integrates a dynamic scheduler between recurrent blocks that manages recurrent KV-cache states and asynchronously prepares future batches based on exit-likelihood estimates.
  • 99% Theoretical Limit Realized: Validated on Ouro 1.4B and Huginn 3.5B, CDB achieves up to 99% of the upper-bound theoretical speedup, clearing the path for production deployment of adaptive-depth architectures.
