Mercury 3 diffusion LLM. Inception released Mercury 3, a diffusion language model that refines full answers instead of generating token by token, claiming over 1,000 tokens per second and leads over GPT-6 Luna and Claude Haiku 5.5 in eight of twelve internal benchmarks. It supports up to 1 million tokens and targets real-time agent and wearable apps.

Vercel durable-harness. Vercel open-sourced durable-harness, an npm package that wraps Pi, OpenCode, Claude Code, Codex, and fx to keep coding agent sessions alive through crashes and timeouts by storing sessions in durable logs. Finished model and tool calls are replayed from logs, never re-run or billed twice.

Patch the Planet plugins. Google published patching-bugs and regression-hunt plugins that let engineers delegate patch development and regression checks to agents, born from the Patch the Planet initiative with OpenAI. In preliminary evaluations, regression-hunt produced 25% fewer false positives than a baseline Codex agent.

2-bit residual decoding. A speculative decoding scheme keeps a 2-bit model on GPU and exact 8-bit residual in system RAM, with only activations crossing PCIe. Early PyTorch measurements show 2-bit+8-bit residual is closer to bf16 than Q8_0, about half the KL divergence.

Vocabulary specialization. Specializing an SLM vocabulary around token cost rather than frequency cut measured inference cost by 77% in a production Portuguese essay grader built on Qwen3-4B, without changing the base model.

KLS conjecture solved. Microsoft researchers solved the 31-year-old KLS conjecture in high-dimensional geometry using a human-directed agentic research process where AI explored mathematical possibilities and researchers pruned and redirected the search. The result establishes a universal geometric principle for log-concave distributions and was independently machine-checked.

What breaks 4B agents. A 50-run evaluation of ten agent harnesses on Qwen3.5-4B found tool-call parsing was not the main failure; exact-match edits that skipped blank lines, context pruning, and harness-specific quirks caused most failures. Six of ten agents passed all five small tasks.

NVIDIA Kumo Relational. NVIDIA Kumo Relational is a pre-trained relational foundation model that predicts outcomes directly on enterprise databases with no task-specific training or feature engineering. Across 41 tasks on 15 databases it beat supervised relational deep learning and AutoGluon ensembles by 8% MRR on SAP SALT.
