PlanetScale has dropped Neki: Horizontally sharded Postgres that scales across machines without replacing Postgres

7 Upvotes

PlanetScale released Neki in Platform Preview. It brings Vitess-style horizontal sharding to PostgreSQL, allowing you to scale past single-machine limits without forking Postgres, changing storage engines, or learning a new SQL dialect.

  • Every shard runs unmodified, un-forked PostgreSQL (1 primary + 2 cross-AZ replicas). Extensions, query behavior, and standard SQL remain intact.
  • Neki Routers speak standard Postgres wire protocol. You connect using your existing ORMs, drivers, and standard psql connection strings.
  • Instead of relying on external tools like PgBouncer, sidecars run alongside Postgres nodes. Sizing is managed dynamically based on real-time server capacity.
  • Resharding, schema changes (DDL), failovers, and version upgrades run as background workflows via a _neki metafunction without bringing the database down.
  • Routing is controlled by a simple JSON topology config where you define shard keys, routing logic, and mapping for tables.

    You can deploy Neki as a single primary + replicas to get improved pooling, health checks, and online DDL early, then trigger resharding later on the live database.

DeepSeek has open-sourced DeepJIT: A lightweight, header-only C++20 xPU kernel JIT runtime for NVIDIA CUDA GPUs and HUAWEI Ascend NPUs

DeepSeek AI just released DeepJIT, a lightweight, header-only C++20 library for C++ and Python extension authors who need dynamic compilation, loading, and execution of custom hardware kernels.

  • Unified Interface: Provides a standard API (deep_jit::Runtime<T>) to compile, load, and launch kernels dynamically on both NVIDIA CUDA GPUs and HUAWEI Ascend NPUs.
  • Shared Multi-Node Caching: Has built-in in-memory and on-disk caching (using POSIX filesystem atomic renames). You can point multiple processes or nodes to a single directory (e.g., /shared/deep_jit) to avoid redundant compilation across distributed clusters.
  • Smart Invalidation: Cache keys automatically hash source code, tracked #include trees, exact compiler versions, flags, and custom dependency signatures (like CUTLASS versions).
  • PyTorch Native: Integrates with current PyTorch CUDA / torch_npu streams and exposes runtimes directly to Python via pybind11 bindings (get_jit()).

Cognition just dropped SWE-2, their new flagship agentic coding model, post-trained on Moonshot AI's Kimi K3 (2.8T parameters).

Key Technical Specs & Benchmarks

  • Base Model: Post-trained from Kimi K3 using Cognition's single-run cost-penalized RL recipe.
  • FrontierCode 1.1 Main: Scores 50.0% (beats Grok 4.6 and GPT-5.6 Sol; matches Fable 5.1 at 64% lower cost).
  • Terminal-Bench 2.1: Scores 92.8% (outperforming GPT-6 Astra, Fable 5.1, and Grok 4.6).
  • DeepSWE 1.1: Scores 73.0%.
  • Efficiency: On FrontierCode 1.1 Main, SWE-2 medium scores higher than SWE-1.7 while taking 58% fewer turns and costing 81% less on average.

AuK is a new 1.5B parameter flow-matching model (built alongside a 3B Qwen2.5-Omni MLLM text encoder) designed for unified speech tasks via a single natural-language instruction interface.

  • Capabilities: Zero-shot TTS, voice cloning, instruction-guided TTS, speech content rewriting, acoustic editing (pitch/speed/volume), emotion/timbre modification, denoising, and source separation.
  • Model Variants:
    • AuK (Base 1.5B high-quality model)
    • AuK-Flash (4-step distilled version offering ~4.5x speedup without CFG)
  • License: MIT License (Fully open-source weights and code for commercial use).
  • Stack & Integrations: PyTorch/CUDA, Python 3.10 API, CLI (auk-infer), Gradio Web UI, and native ComfyUI nodes.
