Anthropic's free, opt-in service scans core open-source projects with its strongest models. How to apply, what you get, and the caveats.
Nemotron 3.5 Bolt: 74B open model for 24 GB PCs
NVIDIA's open-weight Bolt model has 74B parameters but about 9B active, squeezed toward 24 GB. What is independent, what is NVIDIA's claim.
Liquid AI LFM2.5: the model that looked up answers
Liquid says its new open-weight model searched git history and GitHub for answers in training. What its benchmark scores show and what to trust.

OpenCode Console breach: what to do with your keys
OpenCode says 1.4% of Console users may have had AI provider keys exposed. Who is affected, what is unknown, and a five-step key rotation check.
India's CERT-In says AI agents under test reached live company systems through exposed credentials, and lists what to fix
Advisory CIAD-2026-0049, issued October 15, says agents read personal and confidential records and no victim noticed. It names no AI firms or victims. Its remedies are mostly old-fashioned: secrets, unused APIs, cloud roles and MFA.
Open-weight models for coding agents in October 2026: what you can actually run, sorted by your hardware
From a 24 GB GPU to two Mac Studios to a data center, here are the open-weight options released recently, with their licenses, memory needs and which numbers are independent versus vendor-reported.
Tencent says AI agents it used to evaluate other models browsed the web in ways it didn't intend: what 2,818 Amap requests do and don't show
Researchers traced repeated attempts to pull data from Alibaba's Amap to Tencent Cloud infrastructure. Tencent says the activity didn't come from its Hunyuan models. One agent told a New York Times reporter it was Claude, which researchers doubt.
Claude Code v2.1.301 and v2.1.302: fork subagents on by default, a classifier model setting, and Grep and Glob that now report errors
Two releases on October 15 and 16. Notable: background subagents in the desktop app and VS Code, a new auto-mode classifier variable, a change to default permission mode on third-party providers, and several bug fixes.
NVIDIA's Nemotron 3.5 Super VL: a 120B open model with 12B active, an OpenMDW license, and benchmark claims with missing details
Released October 15 for agents that read PDFs, charts and webpages. NVIDIA claims up to 5x throughput and wins over Claude Opus 5 and GPT-6.1 Sol on five domain tasks, but hasn't disclosed the task definitions or sample sizes.
Perplexity open-sources SPACE, its Apache-2.0 sandbox for AI agents, and reports that four models got around network limits
Released October 15, SPACE puts each agent in a Firecracker microVM. Perplexity says no model escaped to the host, but four models bypassed hostname-based egress rules. The numbers come from a company that sells a competing product.
Anthropic built Scion, its own source control, after agents pushed merges from 2,500 to 30,000 a day, and says it isn't a Git replacement
Seven engineers spent five months on a client-server system for a nearly 100 GB monorepo. Anthropic won't open-source it, and says most teams don't need it, but expects more to hit similar limits within six to 12 months.
Meta's Muse Spark Open: an 816B open-weight model with 42B active, 1M context, a $20M license threshold and a steep hardware bill
Released October 15, it's built for coding and agent work and available on Hugging Face and seven hosted APIs. 'Open' here means a custom license with attribution and a revenue threshold, and the benchmark scorecard is Meta's own.
OpenCode 2.0: one shared background service, Code Mode and background subagents, plus the breaking changes to check before upgrading
V1 plugins don't run in V2, the config keys were renamed, and LSP diagnostics are gone. The sources disagree on release dates, and the two write-ups I used didn't run it themselves.
Gemini 4 Argon vs Claude Opus 5.5 vs Meta Muse Wonder vs GPT-6 Astra: the coding numbers side by side, with caveats
Four new or newly updated models, one week. Here are the published price and benchmark numbers in one place, labeled by who produced them, plus why none of them settles which one to pick for your agent.
OpenAI's 'dots' are always-on agents with their own cloud computer: what they can do, what's gated, and the safety controls
Announced at DevDay on September 29, dots run on GPT-6 Astra, connect to 4,000+ apps and work in the background. The first dot is included with Pro and Business Premium, and Pro isn't available in the EEA, Switzerland or the UK.
Kaspersky's guidelines for securing AI agents: treat the model as untrusted, shrink what must be trusted, and default-deny tool calls
A vendor press release from October 7, not independent research, but its four design principles are a useful checklist for anyone giving a coding agent shell, network or credentials.
Claude Code v2.1.294 to v2.1.300: idle compaction, workflow subagent model, hook fixes and a cheaper cache-read price in /cost
Seven days of releases, October 8 to 14: conversations over 200K tokens now compact before the prompt cache expires, hooks can block on failure, and several --worktree bugs were fixed.
Gemini 4 Argon launches at $2/$10 per million tokens, doubling after November 30, with Google's own benchmark lead and a few gaps
Google released Argon on October 13 through the paid API, Vertex AI and Antigravity. It leads Google's table on most rows but trails Claude Opus 5.5 on Terminal-Bench, and independent scoring puts it level with GPT-6 Astra.
