This Week in All Things AI - Week 22-2026

This Week in All Things AI covers key developments in models, agents, tools, infrastructure, and policy curated from discussions in the All Things AI Telegram group.

If you follow AI for work, research, investing, or just to understand where the technology is heading, this weekly brief is a concise way to scan the most important launches, risks, and resources in a few focused minutes.

Major developments this week included xAI completing training on Grok V9-Medium (1.5T parameters) with a public release expected in 2–3 weeks, alongside plans to open-source its current v8-small model by year-end. OpenRouter raised $113M at a $1.3B valuation as Xiaomi's MiMo slashed API pricing by up to 99% and MiniMax teased its M3 sparse-attention architecture. Anthropic released Opus 4.8, Stanford launched the open-source OpenJarvis agent framework, and Cursor announced its inaugural Compile conference. China's Shanghai Futures Exchange began researching AI token futures as Tomasz Tunguz argued that competitive advantage now lies in the orchestration layer rather than foundation models. The week closed with Kirkland & Ellis committing $500M to build a proprietary in-house AI platform and ElevenLabs launching Dubbing v2, a model that preserves speaker emotion, tone, and pacing across 90+ languages.

The sections that follow walk through these items day by day, with short context and links so you can dive deeper into the pieces most relevant to your work or interests.

Elon Musk announced that training of Grok foundation model V9-Medium with 1.5 trillion parameters is complete, with positive evaluation results.

Supplementary training included substantial Cursor data, with fine-tuning now underway and reinforcement learning scheduled to start in a few days.

Public release is expected in 2-3 weeks, marking a major upgrade over the current 0.5T v8-small model, particularly for challenging coding tasks.

He also announces that xAI will open-source its current 0.5T Grok model (v8-small) by the end of 2026, stating it should remain quite useful even after newer models launch.

We're seeing a Cambrian explosion of AI models, and it's happening on OpenRouter.

The future of AI is neurodiversity:

OpenRouter
@OpenRouter

Today we're announcing our $113M Series B led by @CapitalGVC.

Over the last 6 months, weekly volume on OpenRouter grew from 5T to 25T tokens as AI rapidly shifts from experimentation into production.

We're excited for what comes next.

OpenRouter is now serving 1.5 quadrillion tokens/yr!

That token run rate is:

— 15-30% of Google APIs
— 20-40% of OpenAI
— >50% of Microsoft Azure Foundry

That's 15x larger than when we invested a year ago.

Revenue has already doubled since this $1.3B round was done in Feb!

Xiaomi MiMo announced permanent API price cuts of up to 99% for MiMo-V2.5-Pro and MiMo-V2.5 models, with unified pricing across context lengths and new low rates like $0.0036 per 1M input cache hit tokens for Pro.

Token plans received major upgrades delivering 5–8× more credits at the same price points, with all existing subscriber credits fully reset as a thank-you, while MiMo-V2.5-TTS stays free temporarily.

Xiaomi MiMo
@XiaomiMiMo

Better inference efficiency, lower costs, broader access.

MiMo-V2.5 Series API pricing is now permanently reduced — by up to 99% compared to previous pricing.

Unified pricing across all context lengths.

MiMo Token Plans have also been upgraded:

• 5–8× more usable tokens

Behind the MiMo API Price Reduction:

The deepest price cut, up to 99%, is for Input (Cache Hit). The core reason is our inference framework now supports hierarchical KV cache optimization for SWA. Production inference engine tests show this optimization increases cached token

Tomasz Tunguz of Theory Ventures with a post where in he articulates that in the AI era, the core differentiator in software is not the model itself but the “harness” layer that tames a general LLM into a reliable, domain-specific agent by combining seven capabilities (context, tools, orchestration, state, sandboxing, observability, and cost optimization).

The article argues that when everyone can access similar foundation models, competitive advantage shifts to whoever builds the best harness around the model. This harness “domesticates” a powerful but wild LLM into a dependable system that can safely execute real workflows in specific industries.

[**Software After AI**
\Software is no longer about UX & data. It is about the harness, the layer that turns an LLM into a reliable agent. Seven components define the new stack.
https://tomtunguz.com](https://tomtunguz.com/harnessing-ai/)

In response Brent Maxwell writes

In my engineering teams, nobody can tell the difference between gpt-5.5, claude-4.7, gemini-3.5-flash or composer-2.5.
There is no winner right now in the model wars.

The harnesses are totally the right thing to focus on - they are making or breaking development processes for us. When we figure out how to manate the harness better, we ship faster with less time stuck in PR. When one of our devs just uses the default agent config in the IDE, it really doesn't give them the same amount of leverage.

Shanghai Futures Exchange Explores AI Token Contracts

China’s Shanghai Futures Exchange is in early-stage research on futures contracts tied to AI tokens, the smallest unit of information processed and billed for by AI models. These contracts would let companies hedge against volatile AI compute costs along the AI supply chain, similar in spirit to commodity or energy futures.

While U.S. exchanges like CME and ICE are moving toward futures tied to GPU rental/compute capacity, China’s concept would be directly linked to AI token consumption used for pricing AI services. This represents a different abstraction layer: the U.S. focuses on hardware capacity, whereas China targets the usage-based “digital fuel” that powers AI models.

China’s daily AI token usage has exploded roughly 1,000x since early 2024, reaching more than 140 trillion tokens a day by March 2026, underscoring surging demand and cost exposure. Token-based derivatives are being framed as a potential new asset class, with figures like BlackRock’s CEO noting that futures on compute could become a distinct financial market.

BREAKING:

Anthropic just dropped Opus 4.8—and it is a MONSTER

We've been testing for about a week @every and our verdict is they could've just called it Opus 5, it's that good.

Here's our vibe check:

Stanford Unveils OpenJarvis: Efficient AI Agents for Your Devices

Stanford researchers from Hazy Research and Scaling Intelligence Lab released OpenJarvis v1.0, an open-source framework that builds personal AI agents to run locally on devices. It emphasizes 'Intelligence per Watt' with swappable components like local models, engines, agents, tools for apps like Slack and email, and self-improvement features. Users get eight ready-to-run agents for tasks such as morning briefings and code review, installable via a simple one-line script across CLI, web, desktop, or messaging apps. Benchmarks show it handles most queries at interactive speeds with far lower costs and latency than cloud systems, positioning it as a privacy-focused alternative to massive data centers.

@JonSaadFalcon

The dominant story in AI has been the growing cloud: bigger clusters, larger models, more gigawatts.

We believe the future is in the opposite direction: on-device inference, smaller models, watts instead of gigawatts.

Today we're releasing @OpenJarvisAI v1.0: a personal AI

Kirkland & Ellis LLP is one of the world’s most successful and profitable “Big Law” firms with approximately 4,000 attorneys across 23 offices. It consistently ranks at or near the top of revenue and profitability metrics.

Kirkland & Ellis is committing $500 million over the next 3–4 years to build its own proprietary AI platform and custom tools. This is one of the largest and most ambitious technology investments ever announced by a law firm.

Key details include:

This move sits at the center of a key debate in legal technology: buy vs. build for AI. Many top firms rely heavily on specialized platforms like Harvey, CoCounsel (Thomson Reuters), or Lexis+ AI. Kirkland’s approach prioritizes:
