Products & Applications

Perplexity launches "Computer": an all-in-one agent workstation with multi-model orchestration. Perplexity released Computer, letting users research, design, code, deploy, and operate from a single interface. It uses parallel asynchronous sub-agents plus a coordinator model that picks different models per task, with usage-based billing, spending caps, and memory/file/tool management. Available first to Max users.

  • Claude Code turns one: from IDE assistant to legacy-system modernization tool. Anthropic is positioning Claude Code as its coding agent foundation and unveiled a modernization offering for legacy systems like COBOL. Though only a blog use case, markets read it as a threat to IBM's mainframe services, briefly pushing IBM stock down over 10%. Whether it can truly modernize critical financial systems remains to be validated.

  • GitHub Copilot CLI is GA, adding repo-level "/research" analysis. Copilot CLI announced general availability plus a new /research command that performs deep investigations of entire repositories using GitHub code search and MCP tools, generating reports exportable as gists. Terminal titles show live task status.

  • Feature intro | GA announcement
  • Nous open-sources Hermes Agent: a local multi-agent workbench with long-term memory. Hermes Agent is an open-source Python project with multi-level memory, sub-agents, filesystem/terminal control, and browser actions, with seamless session continuation across CLI and multiple messaging apps. Combined with Atropos, it supports large-scale data generation and RL pipelines.

  • GitHub repo | Announcement and free trial
  • LM Studio launches LM Link: secure remote access to local models via Tailscale. LM Link lets users securely reach local LLMs on home or cloud machines from outside the network without exposing ports. The community wants mobile support and a mode independent of third-party accounts.

  • Models & Capabilities

    OpenAI launches GPT-5.3-Codex, emphasizing coding and inference speed. Now available in the API, community tests show it is roughly 25% faster than 5.2 with fewer tokens per task, performing strongly on SWE-Bench Pro and other coding benchmarks. Pricing: $1.75/M input tokens, $14/M output tokens — sparking "expensive but strong" debates.

  • Dev announcement | Cline benchmarks | Pricing discussion
  • Qwen 3.5 Medium series: open weights, ultra-long context, MoE. Alibaba released Qwen3.5 27B/35B-A3B/122B-A10B with same-day support in vLLM, GGUF, LM Studio, and Ollama. Official claims: near-lossless at 4-bit + KV quantization, 800K–1M token context. Developers report the 35B-A3B approaches commercial cloud models in local agent tool-calling, activating only ~3B parameters per token.

  • Release and tooling | Long context and FP8 weights | Local agent review | Arena adds Qwen3.5
  • Grok-4.20-Beta1 takes #1 on Arena Search. xAI's Grok-4.20-Beta1 ranks first on Arena Search with a score of 1226, ahead of GPT-5.2 and Gemini-3, and ties for 4th on the Text leaderboard at 1492 — showing its retrieval and general QA are competitive with frontier closed models.

  • Arena leaderboard | Announcement
  • Liquid AI releases LFM2-24B-A2B: a sparse MoE with 2B effective parameters. A 24B-parameter model activating only 2B per token, runnable on 32GB-memory devices, with day-one support in llama.cpp, vLLM, SGLang, and various GGUF quantizations. Pretraining has passed 17T tokens and continues; it will later become LFM2.5.

  • Reddit discussion
  • Diffusion LLM inference engine claims ~1000 tok/s. Inception Labs and others demonstrated diffusion-based LLM inference reportedly reaching ~1000 tokens/second, further accelerated by test-time scaling techniques like Ψ-Samplers. These remain frontier experiments; real-world performance awaits community replication.

  • Agents & Tooling

    Karpathy: coding agents have "genuinely become useful" since December 2025. Karpathy described completing an entire local deployment via agents — SSH setup, vLLM installation, model pulling, load testing, service startup, frontend, systemd config, report writing — almost fully automated. He believes coding agents have qualitatively improved in long-task coherence and persistence over the past two months.

  • Karpathy thread
  • ActionEngine: GUI agents as one-shot generated "programs" rather than step-by-step clicking. ActionEngine treats web/GUI interaction as graph search, exploring a state machine offline so that at inference time a single LLM call generates the whole action program — claiming better success rates, latency, and cost than step-by-step visual agents.

  • Method intro
  • OpenClaw as a "system-level" agent: from desktop control to long-term memory stacks. OpenClaw is widely used as a local OS-level agent controlling files, browsers, and machines. People build email/CRM/finance automations with it while worrying about safety — one user granted root access had their trash wiped; others built three-tier persistent memory stacks for it.

  • Usage thread | Discord discussion
  • Aider community's cheap-and-effective model mix: DeepSeek + Kimi + Mimo. Recommended setup: DeepSeek V3.2 as the main reasoning model (cheap but slower), mimo-v2-flash for fast file edits, and moonshot Kimi-k2.5 for planning on hard problems with mimo implementing the code. Multi-model routing is seen as a good cost/experience balance.

    Karpathy: the real bottleneck is memory orchestration, not raw compute. Karpathy frames LLM compute as a two-tier system — fast-but-small on-chip SRAM vs. large-but-slow external DRAM — arguing that scheduling prefill and decode between the two is the core challenge for long-context, high-concurrency agent workloads, unsolved by both HBM and big-SRAM approaches.

  • OpenAI and Meta receive 160M AMD warrants: effectively "buy GPUs, get stock." Analysis says OpenAI and Meta secured warrants for a combined 160M AMD shares tied to large GPU purchase deals, with a strike-price target around $600 and theoretical returns up to $192B — an equity rebate that further binds compute suppliers to AI companies.

  • Deal analysis
  • Blackwell GPU cloud price war: Packet.ai from $0.66/hour. Packet.ai published Blackwell cloud pricing of about $0.66/hour on-demand or $199/month for training. More individuals and small teams are turning to rental solutions like Lightning AI clusters instead of enterprise-level B200 purchases.

  • Packet Blackwell pricing | Lightning AI clusters
  • Zagora: stitching scattered internet GPUs into a model-training cluster. Zagora is building a distributed fine-tuning platform that combines consumer GPUs over the public internet to train 70B+ models, currently supporting GPT-OSS, Qwen 2.5, Mistral, and other Transformer families using Petals/SWARM-style pipeline training.

  • Research & Methods

    Agent reliability research: capabilities rise fast, but "not failing" hasn't improved much. Multiple works note that while benchmark scores soar, reliability gains are limited: agents often derail on a single tool call, with errors compounding. Some propose minimal safety benchmarks that must be strictly obeyed — e.g., never sending emails regardless of surrounding context.

  • Reliability survey discussion | Failure modes summary | Minimal safety benchmark proposal
  • Trace-Free+: teach models to "rewrite tool descriptions" before agents use tools. Intuit found tool-calling performance depends heavily on tool description wording. Trace-Free+ uses curriculum training so the model learns to rewrite complex tool docs into agent-friendly formats — no extra traces at inference, more stable in multi-tool settings.

  • Method intro
  • Goodfire: interpretability at trillion-parameter scale without crushing inference performance. Goodfire demonstrated infrastructure collecting billions of activations from very large models with minimal latency impact, including a case of live "course-correcting" chain-of-thought via activation analysis — engineering-grade interpretability for safety and debugging teams.

  • Technical thread
  • Midtraining: a small training stage between pretraining and instruction tuning, highly sensitive. A new paper systematizes "midtraining" — an additional stage between pretraining and post-training — finding it can reduce forgetting and improve downstream performance, but is very sensitive to timing and data distribution; inserting it carelessly can hurt.

  • Preprint
  • Diffusion/Flow Matching survey series: diffusion is rewriting LLM training, not just images. The Eleuther community curated recent work from Rectified Flows and Flow Matching to Diffusion Forcing, plus new papers from ByteDance, Tencent, and others, with a video lecture playlist.

  • Industry & Company News

    Anthropic acquires Vercept to strengthen Claude's "computer use." Anthropic acquired Vercept, a computer-operating agent company. The founders say the goal is for AI to actually click through interfaces and run tasks for users — especially non-technical ones — reinforcing the Claude Code / Claude Tools product line.

  • Anthropic announcement | Vercept founder's retrospective
  • Wayve raises $1.5B: embodied AI expanding from autonomous driving to general robotics. UK autonomous driving company Wayve closed a $1.5B Series D at an $8.6B valuation, with SoftBank, Microsoft, NVIDIA, and Uber participating. It plans supervised robotaxi pilots in 10 cities in 2026 and will sell embodied AI hardware/software to automakers and robot makers from 2027.

  • Funding and roadmap
  • Quiver AI raises $8.3M to turn images/copy into SVG with one click. a16z-led Quiver AI announced an $8.3M seed round and released Arrow-1.0: input a design sketch or text description, output editable SVG vector graphics for UI, posters, and icons — potentially a high-frequency tool for front-end developers and designers.

  • Funding and model release
  • Policy, Governance & Safety

    US Department of Defense negotiates with xAI/Grok, Anthropic, and OpenAI: military-use red lines in the open. Reports say the Pentagon reached a deal to use Grok in classified systems and demanded Anthropic allow Claude for "all lawful uses," including mass surveillance and weapons development. Anthropic publicly refuses mass surveillance and autonomous weapons, and reportedly faces threats of invoking the Defense Production Act or being designated a supply-chain risk.

  • xAI-Pentagon deal report | Ultimatum to Anthropic | Community discussion
  • Anthropic softens RSP constraints, criticized for "safety pledges buckling under commercial pressure." TIME reports Anthropic dropped its Responsible Scaling Policy's most aggressive clause: not training stronger models until safety is adequately demonstrated. Its chief scientist said unilateral commitments are unsustainable when competitors don't follow — some see a pragmatic compromise, others a side effect of absent global regulation.

  • TIME report | Community discussion
  • AI + surveillance: Jeff Dean publicly opposes mass-surveillance uses. Jeff Dean stated on X that mass surveillance suppresses free speech, is easy to abuse, and violates constitutional principles. Community members worry that delegating enforcement to agents that cannot refuse "unlawful orders" makes policing systems harder to constrain.

  • Jeff Dean statement | Risk discussion
  • Energy constraints surface: US considering requiring AI companies to build their own power. Reports suggest the US government, worried data center and AI loads will strain the grid, is pushing large AI/cloud vendors to shoulder their own power supply so the public doesn't pay for rising electricity prices. Scaling is now an infrastructure and energy policy problem, not just algorithms and GPUs.

  • Energy pressure and self-power rumors
  • Red-teaming and jailbreak automation: self-updating jailbreak agents raise major compliance risks. In the BASI community, someone built a self-updating "jailbreak agent" using OpenClaw + DeepSeek-R1 that automatically generates multi-turn covert jailbreak prompts for Claude, GPT, Gemini, Grok, and more. Peer reviewers noted it violates virtually every vendor's TOS and that seized VPS logs, malicious models, and no rollback plan are major hazards.
