Tencent Cloud open-sourced TencentDB Agent Memory, using context offloading and a Mermaid task canvas to reduce token usage by up to 61% in multi-task continuous sessions while supporting OpenClaw integration and local SQLite storage.

Moore Threads said at the SGLang × MUSA Meetup that the MUSA backend has been merged into SGLang mainline, with 47 PRs submitted and 41 merged as of May 12.

OpenSquilla combines local model routing, vector retrieval, incremental sending, and cache hits to reduce transmitted tokens by more than 90%, while routing simple tasks to cheaper models and complex tasks to stronger models without spending tokens on the routing decision.

SenseNova published SenseNova-U1-A3B-MoT on Hugging Face; the post lists A3B MoT, 8B MoT, and 0.4B LoRA weight links, and says the NEO-unify architecture unifies multimodal understanding, reasoning, and generation in one model family.

The team open-sourced psql_bm25s, a native PostgreSQL access method for exact BM25 retrieval, and says it runs about 23x faster than pg_search on standard benchmarks.

Xiaomi open-sourced MiMo-V2.5-Pro with 1.02T parameters, 42B active parameters, a 1M context window, and an MIT license; the author ran 125 Claude Code sessions through the API, spending $70.12 for 387,380,436 tokens with a 96.3% cache hit rate.

ModelBest, Tsinghua University, and OpenBMB open-sourced MiniCPM-V 4.6, a 1.3B multimodal model that supports full fine-tuning on one RTX 4090 and offers 4x/16x visual token compression for accuracy or speed trade-offs.

maddiedreese ran Andrej Karpathy’s TinyStories-260K on a stock Game Boy Color with INT8 weights, fixed-point math, an MBC5 ROM, bank-switched cartridge storage, and KV cache in cartridge SRAM; the demo uses no phone, PC, Wi‑Fi, link cable, or cloud inference, but output is extremely slow and gibberish.

Cactus open-sourced Needle, a 26M-parameter tool-calling model that reaches 6,000 tok/s prefill and 1,200 tok/s decode on consumer devices, with MIT-licensed weights released on Hugging Face.

Cactus Compute open-sourced Needle, a 26M-parameter tool-calling model that reaches 6,000 tok/s prefill and 1,200 tok/s decode on consumer devices, using an attention-and-gating architecture with no MLPs.

China’s open AI model community forms a self-reinforcing loop, with domestic open model downloads rising by more than 200% quarter over quarter.

The author surveyed export methods across 5 consumer platforms: Taobao supports exports, JD.com needs a Codex-built Chrome extension, Ele.me can provide Excel exports by request, Meituan Waimai has no method, and JD.com plus Dianping tools are open sourced.

ByteDance open-sourced DreamLite, a 0.39B-parameter unified diffusion model that generates or edits a 1024×1024 image on an iPhone 17 Pro in about 3 seconds, using 4-step DMD2 distillation and on-device offline inference without cloud dependency.

Reddit user kexxty ran 288 structured-output calls through OpenRouter models, including Llama 3, Mistral, Command R, DeepSeek, and Qwen, and found similar JSON failure categories across local and API-only models. The MIT-licensed Python library outputguard validates against JSON Schema, applies 15 ordered repair strategies, includes 2,001 tests, and has no LLM provider dependency.

Anthropic open-sourced a financial services AI template library on GitHub, including 10 end-to-end agents, 7 vertical industry plugins, and MCP connectors for 11 financial data providers, with deployment paths from personal plugins to enterprise APIs and integrations for Microsoft 365 and private cloud.
