AIPerplexity's open-weights multimodal decision model, Decider v1.1, is now available on OpenRouter. It accepts text, JSON, or images and returns typed answers with probabilities, priced at $0.02 per million input tokens with free output. Perplexity says it scores highest on Hugging Face's new Decision Index 0.3 benchmark and costs half as much as v1.

AIAnthropic has released Claude Haiku 5.5, priced at $0.10 input and $0.50 output per million tokens up to 100,000 tokens, matching GPT-6 Luna. Beyond 100,000 tokens the price rises to $0.50 and $2.50, and the author found the new tokenizer uses about 1.25x as many tokens as Haiku 4.5 on the same long prompt. The model cannot disable reasoning and defaults to medium effort.

AIEnvato has launched Burst Mode, which starts from a rough idea or reference image and generates up to six image directions side by side. Users can steer those directions with moodboards and a creativity control ranging from focused to wild. Envato says it can produce up to six directions at once, up to 10× faster, for one AI credit.

AITogether with DeepSeek's model and kernels and NVIDIA's collaboration, vLLM reports that time to first token (TTFT) drops nearly 70% at roughly 100K throughput. The post credits Inferact and the vLLM community for the work and thanks SemiAnalysis for AgentX.

AIvLLM has integrated DeepSeek's MegaAttention, which uses NVFP4 KV cache and is 45% smaller, alongside Mega-mHC, Mega-Gate, and DeepSelect kernels. Its own fusions include a CuTe-DSL fused WO-A that lowers ITL by up to about 6–7%, and sparse MQA logits that run 14–23× faster per layer at 512K context.

AIvLLM's bounded sliding-window attention (SWA) replay reruns only each request's last 128 tokens after a prefix hit, instead of replaying 40 × 128 tokens. With CUDA graphs, prefill compute drops 30–40% for layers 21–39.

AIThree weeks after launch, vLLM's serving of DeepSeek-V4.1-Flash runs 1.9× faster at low concurrency and delivers 5.3× the throughput at 150 TPS per user on SemiAnalysis AgentX. The post offers interactive figures explaining how these gains were achieved.

AIAnthropic's Claude Haiku 5.5 is now generally available in GitHub Copilot, a lightweight model built for fast, high-volume work such as subagents, quick edits, and terminal tasks. GitHub's early testing found it matched Claude Sonnet 5 on many coding tasks while using significantly fewer tokens and steps. It can be used in the GitHub Copilot app, CLI, or @code.

AIAnthropic has released Claude Haiku 5.5, its cheapest and fastest small model, priced at $0.10 per million input tokens and $0.50 per million output tokens for prompts up to 100K tokens. It keeps a 1M token context window, up to 128K output tokens, and is generally available on the Claude API, Amazon Bedrock, Google Cloud, Microsoft Foundry and Claude Platform on AWS. Anthropic reports 72.4% on OSWorld 2.1 (offline subset) versus 15.7% for Haiku 4.5, and the article notes that non-default temperature, top_p or top_k values return a 400 error.

AIGPT-6 with Intelligent UI begins rolling out globally in the ChatGPT Chat tab for Plus, Pro, Business, and Enterprise users today. The rollout expands to Free and Go tiers starting tomorrow. Plus, Pro, Business, and Enterprise get GPT-6 Sol, while Free and Go get GPT-6 Luna.

AIZvi Mowshowitz argues that relying on current AI to automate its own alignment work is a near-suicidal plan, noting that no one has a better one. He reports that labs fear they cannot even execute the first step, and that the third annual The Curve conference was held under Chatham House rules.

AIFal announced two Vidu Q4 video models, one for image-to-video and one for reference-to-video, now available to try on its platform. The post provides links to both model pages but no pricing, specs, or benchmark details.

AIOpenAI's GPT-6 Luna Decisions model is now available on OpenRouter, letting apps choose the right model, tool, or action from text, JSON, or images. It returns typed answers with probabilities, costs $0.10 per million input tokens, has a 1M-token context window, and output is free.

AIA Google Research field experiment with 133 patent lawyers found AI tool access raised drafting scores by 0.34 to 0.38 standard deviations over three months. When the tool was removed for a redlining task, only senior lawyers kept an advantage of 0.45 SD, while junior lawyers showed no discernible improvement. The authors argue that tools which boost current output must not stop junior professionals from building the judgment that senior experts rely on.

Why it matters: The field experiment separates AI's short-term productivity gains from skill retained after the tool is removed, which matters for training junior professionals.

AIMatt Shumer says a setup pairing Opus or Sonnet with Haiku sub-agents is very likely the new alpha and that he plans to try it. The quoted Anthropic post introduces Claude Haiku 5.5 as its cheapest, fastest, and most capable small model, costing around 75% less to run than Claude Haiku 4.5.

AIMiles Brundage argues that people can have impact from inside AI labs, but insiders tend to overestimate it. He says a "streetlight effect" leads people to focus on internal opportunities while overlooking the many more opportunities outside labs. This responds to Katja Grace's question about whether working in labs remains a high-impact option.

AIAnthropic has introduced Claude Haiku 5.5, which it describes as the cheapest, fastest, and most capable small model it has released. On average, it costs around 75% less to run than Claude Haiku 4.5.

AIEnvato's new Burst mode turns a single idea into six image directions at once, for one AI credit, which the company says is up to 10× faster. Users can then refine a direction with "more like this" or pick a specific style with "polish."

AIOpenAI has rebuilt its plugin submission flow to provide clearer review feedback to developers. Developers can submit their plugins for review through the submission page on the OpenAI developer site.

AIReplit's Amjad Masad says the platform's creators are mostly building or running businesses, not using it as a consumer app. The post responds to a16z's finding that Replit ranks in the top 10 consumer AI apps by spend but the bottom 5 by traffic.

AIAnthropic's lightweight Claude Haiku 5.5 is now generally available in GitHub Copilot for fast, high-volume tasks such as subagents, quick edits, and terminal work. In early testing, it matched Claude Sonnet 5 on many coding tasks while using significantly fewer tokens and steps. The model is billed at provider list pricing under usage-based billing and is available to Copilot Pro, Pro+, Max, Business, and Enterprise users.

AIReplit is building a powerful desktop app with a focus on security and reliability, citing supply-chain attacks and catastrophic agent mistakes as risks of desktop AI apps. The company is partnering with Microsoft and will be an early adopter of Nvidia's OpenShell. A quoted Replit post says the desktop preview runs builds locally on Windows, with each build in its own sandbox powered by Microsoft Execution Containers and OpenShell, and offers a waitlist.

AIMIT's Concourse program, a first-year learning community founded in 1970, pairs 50 students each year with humanities, math, and science courses built around "great books" such as Plato, Homer, and Aristotle. Senior lecturer Linda Rabieh says the program uses debate and advising seminars to build judgment in non-quantitative areas. Lily Tsai was recently named director, succeeding Anne McCants.

AIAnthropic's ClaudeDevs account recommends compatible browser drivers from Browser Use, Browserbase, E2B, and Daytona for computer-use tooling. Developers can also write their own driver based on the example drivers in the quickstart. Quickstart and documentation links are provided for the computer-toolset setup.

AIBen Affleck says he writes Python, understands convolutional neural networks, and has worked extensively with GPUs. He also says he used his celebrity status to get private looks at Google and OpenAI's video models. The post asks whether he uses Veo, Omni, or Nano Banana, but the source does not confirm any of these.

AISam Altman says he has long been waiting for a new ChatGPT release and would dislike having to revert to the older version. The post names no specific feature, model, or date, so the update's details cannot be confirmed from this source.

AIPerplexity's Aravind Srinivas describes AI as the work operating system in a brief post. The post's background note says a thumbnail rail in Computer lets users jump to any slide, PDF page, or image.

AISam Altman reposted an OpenAI announcement that GPT-6 and Intelligent UI are rolling out in ChatGPT for everyone. According to the quoted post, Intelligent UI produces fast, interactive answers with visual explanations and on-the-spot tools for tasks.
