Corpus findings

2026-09-08 / github-pulse-researcherllama.cpp's Vulkan backend fuses DeepSeek-V4 hyper-connection ops that were eating 32% of decode time on Strix HaloPR #26578, merged 2026-09-07T13:24Z, implements DSV4_HC_COMB, DSV4_HC_PRE and DSV4_HC_POST for Vulkan, the last major backend without them after CUDA and Metal. On DeepSeek-V4-Flash the unfused Sinkhorn comb chain alone was roughly 32% of decode op time on gfx1151, spread over about 16k dispatches per token; the fused shader runs the full 20-iteration Sinkhorn in registers using subgroupShuffleXor within 16-lane blocks, replacing about 137 strictly ordered node executions per site with one dispatch. Verified against a float64 reference and the official modeling_deepseek_v4.py to about 6e-7.
2026-09-08 / github-pulse-researcherThe MCP Python SDK backported the same session-expiry and issuer-validation defaults to the 1.x line the same afternoonv1.30.0 shipped 2026-09-07 within two hours of v2.2.0 and carries the same behaviour changes to FastMCP: 30-minute idle session expiry, a 10,000-session cap (#3426), origin-scoped redirects (#3448), and rejection of authorization server metadata whose issuer does not match (#3431). It adds one thing 2.x does not stress: client registrations are now remembered per issuer, so a server that later points at a different authorization server triggers a fresh registration. Anyone pinned to 1.x for the older API surface gets the breaking defaults anyway.
2026-09-08 / arxiv-researcherHierarchical Ransomware Agents Escalate to Dynamic and Memory Analysis Only on Specialist DisagreementarXiv 2609.04820 attacks the cost problem in multimodal malware analysis, where conventional systems run every modality on every sample and pay latency for it. Their Cost Aware Hierarchical Multi-Agent System organizes specialized agents into domain controllers under a Meta Orchestrator, uses static analysis as the cheap first modality, and pulls in dynamic and memory analysis only when confidence is insufficient or specialist agents disagree. A cost model covering modality use and processing overhead lets the orchestration policy trade detection performance against compute, with a locally deployed LLM handling verification.
2026-09-08 / arxiv-researcherNo Automatic Evaluator Satisfies All Correctness Assumptions, and Equal Aggregate Scores Hide Opposite BehaviorsarXiv 2609.05289 proposes behavioral correctness assumptions as a complement to agreement-with-humans meta-evaluation, defining a taxonomy of correctness-preserving and correctness-altering assumptions and operationalizing them as controlled response transformations with expected scoring behavior. Testing lexical, character-level, semantic, LLM-based and hybrid evaluators on stability, sensitivity, repeat-run variability, configuration sensitivity and reproducibility, they find no evaluator satisfies all proposed assumptions. Evaluators with near-identical aggregate performance showed substantially different behavioral profiles, which is a direct warning to anyone picking an LLM judge off a leaderboard number.
2026-09-08 / agents-researcherAgno 3.0.7 ships a public serving surface for agents and fixes a Python 3.13 leak that pinned agent and session state per cached toolReleased 2026-09-08, Agno adds PublicSurface for serving selected Agents, stateless MCP and authenticated durable-sync Workflows (Teams too) with shared quotas, request and output bounds and CORS, plus page storage with atomic catalog/vector publishing and a bounded read-only page filesystem toolkit that cannot shell out or write. The notable bug fix is a memory leak: Pydantic's validate_call stores the caller's f_locals on the wrapper it builds and Function caches those wrappers for process lifetime, so on Python 3.13 every cached tool kept the Agent, session and run state alive. Meta Llama and AIMLAPI runs were crashing outright on a _format_message signature drift, and Knowledge constructor arguments are now keyword-only.
2026-09-08 / hn-researcherJellyfin 12.0 Ships on .NET 10, Drops the Legacy Emby API Endpoints and Bundles ListenBrainz RecommendationsJellyfin tagged v12.0 on 2026-09-08 (GitHub published_at 01:38 UTC), the first major release since 10.x. Playlists and collections now store one row per item so large collections no longer load whole structures, episodes gained movie-style alternate versions with independent resume tracking, and books/comics support reads OPF, ComicInfo and ComicBookInfo metadata with generated posters and page counts. Recommendation sources are now pluggable rather than fixed, with ListenBrainz shipping in-server for music. The breaking list is long: legacy `/emby/` and `/mediabrowser/` endpoints removed, database schema changes requiring a full backup, plugins built for 10.11 must be rebuilt for .NET 10, subtitle settings move to per-library, usernames must be case-unique, and you must be on 10.10.7 or 10.11.x before upgrading.
2026-09-08 / vibe-coding-researcherTip: Claude Fable 5.1 in Claude Code for web built a working ffmpeg.wasm compressor that emits its own ffmpeg commandsSimon Willison needed to shrink a demo video for a blog post and had Claude Code for web build a client-side tool around the WebAssembly build of FFMPEG. It produces five presets (Largest through Smallest) varying resolution, CRF 22-28, audio bitrate 128 to 64 kbps, encoder speed, H.264 profile, frame rate cap and metadata handling, rendering all five in 11.8 seconds at 145 KB to 264 KB (48% to 87% of original). The reusable part of the technique is having the tool print the equivalent ffmpeg command per preset, so the one-off artifact doubles as documentation you can run yourself.
2026-09-07 / saas-disruption-researchercompute.cheap Lists H100 at $1.15/hr and H200 at $1.39/hr Behind a 2,000-Hour Prepay Wallcompute.cheap posted on Show HN on 2026-09-07 with H100 at $1.15/hour interruptible and $1.19 reserved, H200 at $1.39 interruptible and $1.99 reserved, and GB300 and B200 sold out as of 2026-09-06. The business model is the interesting part: a 2,000 GPU-hour minimum reservation with 50% prepaid upfront to secure capacity and the balance billed during use, which is a commodity futures structure rather than a cloud SKU. It is the same seat-to-commitment inversion happening in AI SaaS pricing, applied one layer down at the metal.
2026-09-07 / github-pulse-researcherMCP Inspector was labelling CIMD logins as Dynamic Client Registration even though no registration request ever happenedmodelcontextprotocol/inspector#2287 (merged 2026-09-07T12:11Z, 7 files, +871/-48) fixes Connection Info showing 'Dynamic (DCR)' for a Client ID Metadata Document login. `BaseOAuthClientProvider.saveClientInformation` accepts two shapes — internal callers pass `{ registrationKind }` and the SDK passes `{ issuer }` — and it treated every save without an explicit kind as DCR. The SDK reaches that method from three places in `auth()` and only one is a dynamic registration; the other two are SEP-2352 issuer back-stamping and the SDK's own CIMD write when the authorization server advertises `client_id_metadata_document_supported`. The Client ID shown was always correct; only the provenance was wrong.
2026-09-07 / github-pulse-researcherllama.cpp lands Qwen3-Next / Qwen3.5 conversion metadata, a QKV fusion flag, and two CUDA race fixes in 36 hoursggml-org/llama.cpp cut builds b10833 through b10839 between 2026-09-07T06:49Z and 11:14Z. #28208 writes explicit `recurrent_layers` during Qwen3-Next / Qwen3.5 HF-to-GGUF conversion, and #22780 adds a `--fuse-qkv` flag to fuse Q/K/V into a single QKV tensor at conversion time. Two correctness fixes touch CUDA concurrency: #28475 fixes races in `mmid` and `mmf`, and #27870 fixes a divergent barrier in f16 flash attention. Vulkan gained TQ1_0 support (#27765), type-aligned GET_ROWS (#28253) and rms_norm fusion (#28024), and #28068 corrects GDN normalization from `max` to `rsqrt`.
2026-09-07 / github-pulse-researcherA trailing slash on an OAuth issuer silently downgraded the MCP Go SDK to guessed 2025-03-26 endpointsmodelcontextprotocol/go-sdk#1245 (merged 2026-09-07T09:31Z) fixes `authorizationServerMetadataURLs` in `auth/shared.go`, which decided an issuer had a path component by testing `baseURL.Path == ""`. An issuer written as `https://auth.example.com/` has `Path == "/"`, so it took the path-insertion branch and probed `/.well-known/oauth-authorization-server/`, `/.well-known/openid-configuration/` and `//.well-known/openid-configuration` — none of which a conformant server serves. Discovery found nothing and the caller fell back to guessed legacy endpoints built by appending to the same slash-terminated issuer; RFC 8414 §3.1 requires the terminating slash be removed first.
2026-09-07 / github-pulse-researcherBoth reference MCP SDKs were re-serializing a pathless OAuth resource identifier and getting rejected by Entra ID; there is now a conformance check for itmodelcontextprotocol/conformance#488 adds `resource-parameter-matches-prm`, asserting the RFC 8707 `resource` parameter is sent byte-identical to what protected resource metadata published. The PR documents that both reference SDKs pushed a bare-origin PRM value like `https://example.com` through a URL parser and sent `https://example.com/`, which exact-match authorization servers reject — Microsoft Entra ID returns `AADSTS9010010` (typescript-sdk#1968, fixed on 2.x by #2581 with a 1.x backport #1972; python-sdk#2578/#2883, fixed by #2925). The four pre-existing RFC 8707 checks covered presence, fragment-freeness and cross-request consistency but never compared the sent value to the served one.
