Model release pace is relentless in February with Google releasing Gemini-3.1 Pro and AliBaba releasing Qwen3.5-397B-A17B on Chinese New Year's Eve. In terms of easy to use agentic tooling/services this week had Hugo Barra/David Singleton's Dreamer, Howie Lu with HyperAgent and Manus with their AI agents within Telegram chats Peter Steinberger of OpenClaw joining OpenAI generated buzz as well as Anthropic tightening the squeeze on using their subscriptions outside of their ecosystem Readers who think others in their family, friends and acquaintances who are curious in knowing more about rapidly evolving AI tools/services/use cases and would benefit from being subscribers of this weekly newsletter are encouraged to share this publication link to them and invite them to subscribe The following messages were posted on the 'All Things AI' Telegram group from Sunday 15th Feb 2026 to Saturday 21st Feb 2026Sunday 15th February 20261via Valerii Anufriev By friends in Nebius, webinar on how to build Claude Code pipelineGet insights on building Claude Code pipelines and learn more about Nebius Academy's upcoming 𝐀𝐏 𝐏𝐞𝐫𝐟𝐨𝐫𝐦𝐚𝐧𝐜𝐞 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐢𝐧𝐠 London program.

Join Denis Volkhonskiy, Rod Rivera, and me for an in-depth webinar we're hosting on 𝐅𝐞𝐛𝐫𝐮𝐚𝐫𝐲 17. I'm sure the tips and tricks for working with coding agents will pay off both during the course and in your everyday engineering work.https://www.linkedin.com2I'm a big fan of Replit, I think its a tool people should generally have in their arsenal and most often it helps you get over the cold-start problem of vibe-coding a custom app for your operational workflow as well as building custom apps rather than wrangling an expensive SaaS product. It's different than Cursor, Windsurf, Claude Code, Codex, Droid, Ampcode and many other which are targetted more towards professional developers and even if you swear by these, I encourage you to give the paid plan of Replit a whirl for a couple of months and see what it can do Here's a video of Replit's features it launched in the last year.

Would have been better for Open AI to "fund" the project in exchange for certain privileges which is what Sam really wants I suspect as they need a differentiator. I wish Peter the best but he hasn't yet witnessed the ugliness of the ravaging American legal system which is not at all like Europe. Concerned this will play out somewhat differently. from a PR perspective the perfect answer to anthropic and a huge huge miss on their part but the legal repercussions will be a bother that said Open AI is no stranger to that so they probably baked it into their equation4Alibaba Unveils Massive Qwen3.5-397B-A17B AI Model on Chinese New Year's Eve The flagship Qwen3.5-397B-A17B features 397 billion parameters but activates only 17 billion per token using a sparse Mixture-of-Experts design, delivering up to 19x faster speeds than predecessors while cutting costs. It handles a 262,000-token context expandable to over 1 million, supports 201 languages, and tops benchmarks like 87.8 on MMLU-Pro and records on agentic tasks. Released under Apache 2.0, it's available now on Hugging Face, with hosted options on chat.qwen.ai, fueling China's push in efficient, open multimodal AI.

Thought some of you might find it useful.I turned a coding editor into the ultimate writing tool | Simon DavisI've been writing updates, docs, and long-form content in a coding editor for the past 6 months. Not because I'm a developer, but because it's the ultimate writing tool. AI chat windows break with long documents. They hit context limits, introduce copy-paste nightmares, and there's no way to see what changed.https://www.linkedin.com3For what it's worth, some paid newsletter subscriptions that have been strongly recommended to me by AI leaders in Silicon Valley. Paid subscriptions come with various perks including subscriber-only articles, courses and initial subscriptions to various AI tools/services I pay for one of them, debating on the others primarily because at this point I don't know if I can give them the time commitment to be an effective learner.

The rule targets open-source tools like OpenClaw and Pi Agent, with enforcement risking bans, while a crackdown limits multiple Max accounts per user.

This is reflected in our progress on rigorous benchmarks. On ARC-AGI-2, a benchmark that evaluates a model’s ability to solve entirely new logic patterns, 3.1 Pro achieved a verified score of 77.1%. This is more than double the reasoning performance of 3 Pro. Sundar Pichai @sundarpichai Gemini 3.1 Pro is here. Hitting 77.1% on ARC-AGI-2, it’s a step forward in core reasoning (more than 2x 3 Pro).

Developers no longer need manual tweaks; a single cache_control field at the top level detects and reuses the longest matching prefix. Thariq from the Claude Code team shared tips like ordering prompts from static to dynamic and avoiding cache-breakers, quipping 'Cache Rules Everything Around Me' in a nod to hip-hop.
