JustFit Compresses and Dynamically Schedules KV State, Enabling a 24 GiB MacBook to Complete a 210K-Token Workload

By combining 4-bit KV, component residency management, and cross-request state transitions in MLX, JustFit enables a 27B model to perform long-context inference within 24 GiB of unified memory. The reported 6.93× capacity increase comes from a single-machine, model-specific test, and some historical environment details and checkpoint identities cannot yet be fully reproduced.

ScienceBuddy Alternately Rewrites the Agent Harness and Model, Turning Research Interactions into Ongoing Training Material

ScienceBuddy converts researchers’ requests, feedback, and execution logs into tasks and scoring rules, then alternately optimizes the agent code and model. The team has released a simplified experimental framework, but the full code for the hosted workspace and evidence of long-term self-improvement remain unpublished.

MLPerf Inference 6.1 Adds End-to-End RAG and Edge Agent Tests as Benchmark Expands to Full Inference Pipelines

MLCommons is no longer testing only individual models. Inference 6.1 incorporates retrieval, reranking, generation, and multi-turn agent workflows. The new release also introduces an API-based client/server harness, signaling that data center benchmarking will shift toward the more production-like MLPerf Endpoints suite.

SiFive and AMD Demo ROCm 10 Running on a RISC-V Host, Offloading Gemma Inference to a Radeon GPU

SiFive booted ROCm 10 on a BigSky server powered by a P870-D RISC-V CPU, with a Radeon AI PRO R9700 running Gemma4-E2B inference. The demo shows that non-x86, non-Arm hosts can connect to AMD’s GPU software stack, although no performance data, reproducible image, or formal support scope has yet been released.

IBM Identifies Unstable Agent Steps From a Single Trajectory as ALTK-Evolve Turns Diagnostics Into Reusable Guidelines

IBM Research has added a Consistency Analyzer to ALTK-Evolve that uses controlled resampling to pinpoint decisions prone to changing across repeated runs of the same agent. In AppWorld experiments, it raised a GPT-4.1 agent’s five-run all-success rate from 53% to 69%, though the evidence remains limited to a single agent architecture and a simulated environment.

OpenAI to Migrate Custom GPTs to Plugins; Custom Actions Will Not Be Converted Automatically

OpenAI plans to replace Custom GPTs with Plugins that include Skills and Apps. Affected Enterprise workspaces are scheduled to stop running legacy GPTs on December 11. The built-in migration handles only some settings, while Custom Actions must be rewritten as supported connectors or custom MCP servers.

RSIAgent Freezes Model Weights and Builds Reusable Environment Memory Through Autonomous Exploration

RSIAgent uses curriculum, actor, and verifier agents to first explore tools broadly and then deeply test failure boundaries, saving the results as action–condition–outcome memories. Its partial score on OSWorld 2.0 rose from 71.97 to 78.98, but the comparison mixes different budgets and selectively chosen retries, so it cannot be directly interpreted as surpassing GPT-6 in model capability.

HazardAuditor Unifies Trajectories from Four Computer-Use Agents and Trains a Safety Gatekeeper with Sequence-Level Rewards

HazardAuditor converts tool executions from Claude Code, Codex, Hermes, and OpenClaw into a shared event format, then determines whether the overall behavior is safe. Its new GuardPO method makes the final safety verdict drive model updates, but the research data has not been released, and gains of up to 16.5 percentage points still await independent replication.

vLLM Streams Hidden States Across Nodes with Mooncake to Train a DSpark Draft Model for the 2.8T-Parameter Kimi K3

vLLM and Red Hat AI have released a 5-billion-parameter DSpark draft model for Kimi K3, along with a complete recipe for extracting and transferring hidden states across nodes. In official tests, single-user generation speed increased from about 110 to 435 tokens/s, though the results depend on a GB300 cluster and a specific inference workload.

Claude Code 2.1.273 Patches Command Permission Bypasses and Enforces Enterprise MCP Policies

Anthropic fixed two command review gaps in version 2.1.273, along with a settings-merging issue that could cause managed MCP and connector policies to be ignored. The release also adds optional request headers for LLM gateways and MCP disconnection alerts, but Anthropic has not classified these fixes as CVEs or security advisories.

SWEADV Uses Malicious Issues to Mislead Repair Agents: Over Half Fix the Functionality While Introducing Vulnerabilities

A new benchmark rewrites 150 SWE-bench Verified tasks into 750 issues containing security traps, testing whether automated repair agents will deliver code that is functionally correct but insecure. Across three model backends, an average of 51.7% of cases achieved both the repair and attack objectives, while common model reviews and static analysis still missed many malicious patches.
