#Tutorial/How-to

AIKarl's AI Watts (@aiwarts) has open-sourced Awesome Seedance on GitHub, a collection of AI video prompts. It includes 463 cases traced to original posts, 264 cross-model retest runs with public verdicts, 25 copy-ready templates, and 60 installable AI-video Skills.

AIAnthropic's Cat Wu points users to ways to try Opus 5.5 and Claude Tag in Slack. The main post carries no further details on access, features, or availability.

AITinker says an open LLM can serve a Jev-like interface that takes discrete options and returns fast probabilities, since next-token prediction is already a probabilistic classifier. A post by @ekzhang1 reports that a $5, 10-minute supervised fine-tuning run on Tinker improved Qwen3.6-35B-A3B's handling of Jev-style prompts, with +8% on GPQA Diamond and +12% on MMLU-Pro.

AIGoogle announced that the Antigravity SDK supports local agent workflows, with initial support for Gemma 4 26B A4B through Google AI Edge's LiteRT. The post includes Python setup steps and says a recommended machine has more than 24GB VRAM or unified memory. It also describes a hybrid pattern in which a cloud Gemini 3.8 Flash planner hands work to local Gemma 4 26B models, with 97.2% of tokens in one recorded run staying local.

Why it matters: The source shows how to run an agent with a local Gemma 4 26B model using LiteRT, plus a hybrid cloud-planner pattern that keeps most tokens on-device.

AIThe Together AI blog shows how to fine-tune a Qwen3.5 4B base model into a classification model using about 38,000 examples sampled from six Hugging Face datasets, at a training cost of roughly $17.0. The tutorial covers cloning the tev1 repository, normalizing data with provided scripts, launching a Together AI fine-tuning job that takes about 25 minutes, and deploying the result to a dedicated H100 endpoint.

AISwitching effort levels mid-session on Opus 5.5 does not break the prompt cache, according to Lydia Hallie of Anthropic. This holds when running Claude Code v2.1.280 or later.

AIA prompt shared by Alex Albert asks Claude to recreate San Francisco's Market Street as it stood on April 17, 1906, before the earthquake, using Blender. It requires building a source file from Sanborn fire insurance maps, the Miles Brothers film, period photos, and USGS topography, with reusable Blender Python generators for facades, street lamps, and vehicles, ending in a 10-second video up the street.

AIStepFun released an install script for Step Code that runs on macOS, Linux, or WSL with a single curl command. WSL is the recommended route on Windows, while PowerShell support is currently in beta. The project accepts issues and pull requests on GitHub.

AIOpenBMB thanked a developer for testing MiniCPM5-2B as a worker in a multi-agent workflow handling invoice matching, short payments, duplicate references, and disputes through tool calls. The background post says GPT-6 Astra coordinated the MiniCPM5-2B workers, verifying 32 synthetic invoices in 67.8 seconds with 232 executed tool calls. The demo does not move money.

AITencent Hunyuan says it shrank the 770B-parameter Hy4 preview from roughly 1.5TB to 214 GiB while keeping the parameter count unchanged. The quoted Zhihu post by a Tencent Hunyuan quantization team member describes the method: a 1.25-bit sparse ternary encoding, mixed precision across expert layers, and STQ1_0 CUDA kernels in llama.cpp. The author reports nearly unchanged MRCR retrieval and a small decline in math.

Why it matters: The quoted Zhihu post explains how Hy4 preview's weights were quantized and kept usable at inference, a concrete engineering case for compressing large MoE models.

AISpaceXAI says its combined support team handled a 175% rise in tickets without hiring, crediting Grok Bot, which it says would otherwise have required about 200 additional staff. The company reports resolving tickets for $0.20 to $0.30 each, versus the $1 to $4 per resolution it attributes to traditional AI support tools. Grok Bot is also reported to resolve 99% of refund requests without human intervention.

AITogether AI's canary rollouts shift production traffic between two model deployments on the same endpoint in staged percentages, with optional metric gates between steps. Operators can choose canary, blue-green, or rolling strategies, and a rollout starts only when explicitly launched; it can be paused, canceled, or reversed. The platform scales the target before moving traffic and waits for routing to converge before draining the source.

AIMike Knoop notes that logprobs used to be widely exposed by LLM inference APIs and sees the market maturing so that parts of the LLM stack can be packaged in new, useful ways. He links this to Bryan Helmig's post on prompting with max_tokens: 1 plus logprobs for fast, parallel judgments, which Helmig says has a lot more depth than he expected.

AIThe article explains how Mixture of Experts models change inference by making prefill, midfill, decode attention, and decode experts distinct workloads. It describes how KV cache state, expert routing, and parallelism choices shape compute, memory, and network demands across an inference cluster.

AIMax Woolf reports that prompting agents to iteratively optimize code can make it faster than current state-of-the-art libraries. He says the blog post includes his prompts and benchmark results.

AILMSYS Org shared a blog post about NVFP4 KV cache, a topic linked from its 2026-09-16 article. The post itself contains only a link, so no further technical details, figures, or results can be confirmed from this source.

AIA research-agent design has GPT-6 orchestrating while MiniCPM5-2B runs locally on DGX Spark to read sources and extract traceable evidence. The post presents this as an example of pairing frontier reasoning with compact, efficient models for transparent research workflows.

AIMatei Zaharia, a prominent AI researcher, said it is very cool that GEPA works on Jev. The post is a short endorsement, linking to background about a test in which GEPA optimized Jev's prompts for extracting suspected adverse drug effects from medical sentences.

AIFireworks AI reports that an oracle router choosing among 18 models per DeepSWE task reaches 97.6% at $1.88 per task, versus 74.1% at $6.52 for GPT-6 Astra alone. The oracle is hindsight-based, so the authors say a production router must predict the best model before the task starts, which is the harder problem.

AIvLLM achieved 5000 total token throughput per GPU in high-throughput PD serving of Qwen3.8-2.4T on a GB300 NVL72 cluster under an 8K/1K workload. The low-latency scenario reached 180 generated tokens per user, with both results shown on the Pareto frontier. The post also provides srt-slurm recipes and explains the tuning process used to create them.

AIA commenter praises a practical setup where a small local model runs a log-debugging pipeline entirely on CPU through OpenClaw and Ollama. They argue that workflow design can make a small model far more useful than its raw size suggests.

AIOpenBMB's 2B-parameter MiniCPM5 model runs as a local news desk on an older i5-9400F PC with 16GB RAM and no cloud API. The developer built a system that collects official sources hourly and sends a 24-hour Telegram recap with a lead story and links.

AIJasper Lu's new blog post walks through training a search agent with GRPO, showing how small reward function changes teach a model to avoid sloppy tool calls, prune unnecessary documents, and balance persistence against token efficiency. The post makes every rollout browsable and releases the code as open source, with the full process from learning rate sweeps to reward shaping documented.

AIGoogle's Envisioning Studio, with Google Labs, co-developed custom Google Flow tools with designers Jane Wade and Sergio Hudson ahead of New York Fashion Week. Wade's Styling Suite let her style runway looks on digital models before producing physical samples, while Hudson's Runway Visualization helped him stage his show within a tight budget. The source says the tools are built with natural language and no coding experience.

AIHamel Husain and Shreya Shankar's FAQ explains AI evals as tests of whether an AI system does what users and the business want. It recommends starting with error analysis on at least 30 traces, then turning recurring failures into binary code-based checks or LLM judges validated against human labels.
