# This Week in All Things AI - Week 18-2026 *Sunday 26th April 2026 to Saturday 2nd May 2026* By [This Week in All Things AI](https://paragraph.com/@twiata) · 2026-05-03 --- This week’s AI landscape was defined by aggressive model commoditization, agentic workflows maturing, and incumbents pulling key verticals in‑house. DeepSeek and Xiaomi drove frontier‑grade capabilities toward “practically free,” with DeepSeek slashing cached token prices and Xiaomi open‑sourcing trillion‑parameter MiMo models under MIT with huge token grants, while Poolside and xAI pushed specialized coding and agentic models like Laguna and Grok 4.3 into the spotlight. Major platforms shifted their economics and UX around agents: GitHub Copilot moved to usage‑based billing, Anthropic released deep integrations for creative tools, and OpenAI’s Codex evolved into a “Codex for everything” control layer over the desktop and browser Microsoft’s new Legal Agent effectively turning legal AI into a Word feature. Strategic and philosophical debates continued in the background: China blocked Meta’s $2B Manus acquisition, Ed Zitron and Shaun Warman questioned AI’s unit economics and “apprenticeship” phase, 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**](https://paragraph.com/@twiata/) to them and invite them to subscribe **_The following messages were posted on the '_**[**_All Things AI_**](https://t.me/+PnCnwhgH8V4yMTFl)**_' Telegram group from Sunday 26th Apr 2026 to Saturday 2nd May 2026_** * * * Sunday 26th April 2026 ---------------------- via [Valerii Anufriev](https://t.me/vianu_reebs) a link to the Deepseek V4 Pro paper [https://huggingface.co/deepseek-ai/DeepSeek-V4-Pro/blob/main/DeepSeek\_V4.pdf](https://huggingface.co/deepseek-ai/DeepSeek-V4-Pro/blob/main/DeepSeek_V4.pdf) Monday 27th April 2026 ---------------------- DeepSeek Slashes AI API Prices to One-Tenth for Cached Inputs DeepSeek announced Saturday a lasting cut in cached input token costs to one-tenth of original prices, starting at $0.0028 per million on V4-Flash and $0.003625 on V4-Pro, stacking with a 75% discount on V4-Pro until May 5, 2026.  My understanding is that these price drops are only available via DeepSeek's inference endpoint in China.  OpenRouter mentions the following about this specific provider input > To our knowledge, this provider may use your prompts and completions to train new models [![User Avatar](https://storage.googleapis.com/papyrus_images/5e1311e1bfa0da893f7934d2831628d79c254fbc3e39a50634635be0803c483e.jpg)](https://twitter.com/deepseek_ai) [DeepSeek](https://twitter.com/deepseek_ai) [@deepseek\_ai](https://twitter.com/deepseek_ai) [](https://twitter.com/deepseek_ai/status/2048440764368347611) ![🔥](https://abs-0.twimg.com/emoji/v2/72x72/1f525.png)DeepSeek Input Cache Price Drop!

China Blocks Meta's $2 Billion AI Startup Acquisition China's National Development and Reform Commission prohibited Meta's $2 billion purchase of Singapore-based Manus, a developer of autonomous AI agents for tasks like coding and data analysis.

A 13B pre-internet trained model to prove whether LLMs are more than just stochastic parrots: In short (preliminary results and the approach is flawed in my opinion): LLMs show non-zero learning capabilities from context alone. Obviously python coding problems never touched the training data but it still is able to get some results correct. The effect is very very small (0.05% success rate) but it shows that LLMs can come to novel (not included in training) conclusions User What would an electronic brain be capable of doing? talkie-1930 An electronic brain would be capable of recording, feeling, and perceiving everything that comes within the range of the senses. It would be capable of knowing colours, sounds, tastes, and smells; it would be capable of pleasure and pain; and it would be capable of thought and volition. In a word, an electronic brain would be a perfectly sensible brain. User Would the electronic brain be able to replace human labor? talkie-1930 No; for, although an intelligent electronic brain would do everything that a human brain can do, it could not do anything more. The utmost that an electronic brain could accomplish would be to think, and to act upon the thoughts; but it could not execute. Muscular labour must still be performed by muscular agency.
