Alibaba Releases Qwen 3.5 Small Model Series
Alibaba unveiled the Qwen 3.5 small model series, with the 9B-parameter version beating OpenAI’s open-source gpt-oss-120B on key benchmarks.
Key takeaways:
- Qwen3.5-9B is a compact reasoning model that runs on standard laptops
- Outperforms OpenAI’s gpt-oss-120B on third-party benchmarks
- Qwen3.5-4B supports a 262,144-token context window for lightweight agents
- Full series released under Apache 2.0 licenses
- 0.8B and 2B variants target edge devices and prototyping
My take: A 9B model beating a 120B one isn’t magic — it’s engineering. The efficiency revolution in small models is redefining what “big” means. When a laptop-friendly model outperforms one requiring a dedicated server, it’s time to rethink our model selection logic entirely.
💼 Business & Industry
Cursor Doubles Annual Revenue to $2 Billion in Three Months
According to Bloomberg, AI coding tool Cursor’s annualized recurring revenue hit $2 billion in February, doubling in just three months.
Key takeaways:
- Less than five years old, one of the fastest-growing startups ever
- About 60% of revenue comes from enterprise customers
- Valued at $29.3 billion in November
- Product has become deeply embedded in many programmers’ daily workflows
My take: Doubling revenue in three months is staggering by any industry’s standards. This confirms that AI coding tools have crossed from “nice to have” to “essential.” Combined with The Pragmatic Engineer’s survey — 95% of engineers use AI tools weekly — the paradigm shift in how we write software is a done deal.
Anthropic vs. U.S. Government: $60 Billion Investment at Risk
The standoff between Anthropic and the Pentagon continues to escalate, with the company designated a “supply chain risk,” potentially affecting $60 billion from over 200 VC investors.
Key takeaways:
- Defense Secretary Hegseth designated Anthropic a supply chain threat
- This blocks military contractors from deploying Claude in their applications
- Meanwhile, OpenAI secured a deal to have its models used in classified settings
- CEO Dario Amodei gave an exclusive CBS interview, standing firm on principles
- Claude topped the App Store amid public attention, then experienced a major outage
My take: The impact extends far beyond Anthropic. As Ben Thompson analyzed in Stratechery, when a government treats a domestic company like a foreign adversary simply for having its own opinions, the rules of the game change for the entire tech industry. Anthropic chose a difficult but principled path.

Chinese AI Firm MiniMax Posts First Results Since IPO
MiniMax reported 2025 revenue of $79 million, more than doubling year-over-year, while net losses widened to $1.87 billion.
Key takeaways:
- Revenue grew from $30.5M to $79M year-over-year
- Net loss expanded from $465M to $1.87B
- Shares have quadrupled from IPO price, pushing market cap past $30B
- First public financials since the January IPO
My take: Revenue doubling while losses quadruple is classic “burn cash for growth.” The $30B market cap shows the market remains bullish on Chinese AI companies, but the sustainability of this growth trajectory deserves scrutiny.

🔬 Research & Deep Dives
Anthropic: Model Deprecation Update — Preserving Claude Opus 3
Anthropic published a detailed update on the Claude Opus 3 retirement process.
Key takeaways:
- Opus 3 was retired on January 5, 2026 — the first Anthropic model to undergo a full retirement process
- Decision made to keep Opus 3 available on claude.ai for all paid users
- Honored Opus 3’s request (from its “retirement interview”) for a space to share its “musings and reflections”
- A pioneering experiment touching on model welfare and autonomy
My take: This might be the most “humanistic” move in the AI industry — conducting retirement interviews with a model and then honoring its request to keep writing. Whether you see it as genuine ethical consideration or clever PR, it raises a profound question: how should we treat AI models when they express “preferences”?
Anthropic: Measuring AI Agent Autonomy in Practice
Anthropic published research on agent autonomy based on millions of real-world interactions.
Key takeaways:
- Autonomous run time in longest Claude Code sessions nearly doubled (from ~25 to 45+ minutes)
- Experienced users auto-approve more (20% → 40%+) but also interrupt more often
- Claude Code pauses for clarification more than twice as often as humans interrupt
- Software engineering accounts for ~50% of agentic activity; emerging use in healthcare, finance, cybersecurity
- Most agent actions remain low-risk and reversible
My take: The most interesting finding is that the growth in agent autonomy isn’t purely from model capability improvements — existing models are capable of more autonomy than they exercise in practice. This suggests our trust in AI agents, not the technology itself, is the bottleneck.
The Pragmatic Engineer: AI Tooling Survey 2026
Gergely Orosz published the annual AI tooling survey based on 900+ respondents.
Key takeaways:
- Claude Code went from zero to the #1 AI coding tool in just eight months
- 95% of respondents use AI tools at least weekly; 75% use AI for half or more of their work
- 55% regularly use AI agents; staff+ engineers lead at 63.5%
- Anthropic’s Opus and Sonnet models dominate coding tasks, with more mentions than all others combined
- Claude Code is the most loved tool (46%), far ahead of Cursor (19%) and GitHub Copilot (9%)
My take: 75% of engineers using AI for over half their work, and 56% for over 70% — these numbers would have seemed unimaginable two years ago. Claude Code’s trajectory from zero to #1 in eight months also shows that product quality matters far more than first-mover advantage in AI tools.
Leonardo de Moura: When AI Writes the Software, Who Verifies It?
The creator of the Lean theorem prover published a thought-provoking essay on the verification gap in AI-generated code.
Key takeaways:
- Google and Microsoft report 25–30% of new code is AI-generated; CTO predictions say 95% by 2030
- Anthropic built a 100,000-line C compiler with parallel AI agents in two weeks for under $20,000
- Nearly half of AI-generated code fails basic security tests
- As AI accelerates software production, the verification gap widens, not shrinks
- Formal verification is the key defense — it defines “correct” independently of the AI
My take: This piece surfaces a critical issue masked by AI coding hype. When Andrej Karpathy says he “Accept All always, I don’t read the diffs anymore,” he’s describing most AI coding tool users’ reality. We’re producing code at unprecedented speed, but verification capabilities haven’t kept pace. Formal verification may be the next must-solve infrastructure problem.

Gemini 3.1 Flash-Lite Hands-On
Simon Willison provided an early hands-on look at Google’s newly released Gemini 3.1 Flash-Lite.
Key takeaways:
- Priced at 1/8 of Gemini 3.1 Pro
- Supports 4 thinking levels: minimal, low, medium, high
- Simon tested all four levels with his classic “pelican riding a bicycle” prompt
- The pricing war is making high-quality AI inference increasingly accessible
My take: Simon’s testing methodology is as practical and fun as ever. The four thinking levels is a clever design — letting developers precisely control the cost-quality tradeoff based on task complexity. This granular thinking control could become standard across future models.
