DeepSeek released Harness v0.1, an MIT-licensed open-source agent framework where every component — model, tools, storage, agent loop, UI — is a swappable plugin on a Cordis microkernel. Released alongside a Peking University research paper on the formal foundations of dynamic component composition.
Read more →DeepSeek V4-Flash-0731 went from a 7.3 to a 54.4 on DeepSWE with identical pretrained weights — a 645% jump achieved purely through post-training. It's evidence that the gap between "can write code" and "can act as an agent" is largely a training-envelope problem, not a capacity problem, and that post-training is now a first-class axis of model improvement alongside pretraining scale and architecture.
Read more →DeepSeek released DSpark on June 27 — a semi-parallel speculative decoding framework already running in production for DeepSeek-V4 — alongside DeepSpec, an MIT-licensed toolkit packaging three drafting algorithms with complete training and evaluation pipelines. Together they let anyone train a custom draft model for their own target LLM, not just the models DeepSeek ships.
Read more →A detailed engineering account of bringing DeepSeek-V4-Flash up on AMD MI300X reveals the real cost of AMD's software ecosystem gaps: FP8 format fragmentation, missing kernels, and HIP graph constraints that each required dedicated engineering effort before getting to 2,700 tokens/s.
Read more →DeepSeek Reasonix is a DeepSeek-native terminal coding agent that treats prefix-cache stability as a first-class invariant rather than a side effect. With 99.82% cache hit rates in reported benchmarks, it cuts a heavy session from ~$61 to ~$12 — deliberately by coupling tightly to one provider's caching behavior instead of staying provider-agnostic.
Read more →Salvatore Sanfilippo (antirez, Redis) released ds4: a single-model Metal inference engine for DeepSeek V4 Flash that deliberately rejects the general-framework approach. Asymmetric 2-bit quantization on MoE experts only gets a 280B-parameter model into 128 GB RAM with 26–36 t/s generation, 1M-token context, and disk-persisted KV cache on Apple Silicon.
