Sunday 24 May 2026
A Sunday roundup with significant funding news across AI infrastructure, model labs pivoting to agents, and the ongoing cost compression race reshaping the economics of inference.
🤖 Models and Launches
Anthropic, Microsoft in talks for AI chip deal after $5B investment — Microsoft plans to supply its Maia AI chips to Anthropic, which faces compute constraints despite partnerships with Amazon and Google. Maia claims 30% improved performance over current options.
Alibaba releases Qwen3.7-Max as agent-foundation model — Posts top scores on Terminal-Bench 2.0, SWE-Pro, SciCode, MCP-Mark, and GPQA Diamond, with consistent performance across Claude Code, OpenClaw, and custom harnesses.
OpenAI’s Q1 revenue hit $5.7B, beating Anthropic — Strong demand for inference has Amazon, Google, and Microsoft all vying to supply custom chip solutions to the major labs.
DeepSeek makes V4-Pro 75% discount permanent — First-party pricing at $0.435/M input, $0.87/M output, placing V4 Pro on the Pareto frontier. Estimated ~19x cheaper than Claude Opus 4.7 on Intelligence Index benchmarks.
Cartesia Sonic-3.5 ranked #1 TTS model on Speech Arena — Elo of 1218, 42 languages, 82ms end-to-end first audio in production.
💰 Funding and Business
Cursor hits $3B annualized revenue — One of the fastest-growing startups of all time, with 3,000+ customers paying $100K+ annually. SpaceX has the right to buy Cursor for $60B during a 30-day window after its IPO.
Modal raises $355M Series C at $4.65B valuation — Rebuilding the cloud stack for AI workloads from scratch, with strong developer experience. Investors include Redpoint.
Hark raises $700M at $6B valuation — GPU infrastructure, foundation models, hardware, and multimodal products. Reported a 200-hour uninterrupted autonomous run for F.03.
Exa raises $250M Series C at $2.2B valuation — AI search infrastructure hitting major scale milestones.
Turbopuffer crosses $100M ARR and profitable — Just 19 months after $1M, with less than $1M raised. The retrieval/search layer for AI is proving to be where the money accrues.
Manus weighs raising $1B to unwind Meta takeover — China’s regulators ordered the reversal of Meta’s acquisition. Founders may chip in their own money. A deal reversal this large months after completion is virtually unheard of.
ClickUp cuts 22% of staff, introduces million-dollar AI salary bands — Savings from cuts flow directly to remaining staff who create outsized impact using AI.
🔬 Research
Agent compilation/distillation achieves ~100x lower inference cost — A paper shows full agentic workflows (multi-step calls, tool use, scratchpads) can be distilled into weights while preserving near-frontier quality. One of the clearest arguments yet for compiling expensive runtime loops into cheaper deployable models.
Can SAEs capture neural geometry? — GoodfireAI shows sparse autoencoders can represent curved manifolds through feature clustering, moving interpretation from single features to structured ensembles.
NVIDIA’s Gated DeltaNet-2 outperforms KDA and Mamba-3 — Decouples erase and write operations in linear attention with channel-wise gates, with notable long-context retrieval gains on RULER at 1.3B parameters.
LT2: linear-time looped transformer — Combines sparse and linear attention to make looping practical, with a distilled Ouro-hybrid-1.4B model.
AI’s plummeting prices are a software story, not a hardware one — Local open-weight models on older commodity hardware are increasingly competitive with frontier models, putting downward pressure on what labs can charge.
🛠️ Agents and Tools
All model labs are now agent labs — Greg Brockman: “the model alone is no longer the product.” AI21 shuttering its model team to pivot to agents. DeepSeek building a “Harness team” for the first time. The product surface is moving from model to model + harness + workflow + UI + memory.
Cursor shares lessons from building cloud agents — Durable execution, isolated dev environments, self-healing infrastructure, and cleaner separation between agent state and conversation state.
MCP 2026-07-28 release candidate: now stateless — No handshake, no session ID, any request can hit any server instance. First-class extensions (MCP Apps, Tasks), auth hardening, and clearer deprecation policy. Big operational shift for infra teams.
CoreWeave launches Sandboxes in public preview — For RL, agent tool use, and model evaluation workloads.
Weaviate ships built-in MCP server inside the database — Coding agents can ingest a repo and use hybrid BM25 + vector retrieval without extra processes.
Microsoft cancels Claude Code licenses, shifts developers to GitHub Copilot CLI — A move likely driven by financial motives as Microsoft consolidates its AI coding tools.
🔒 Security
Anthropic’s Project Glasswing finds 10,000+ critical vulnerabilities in a month — Partners using Claude Mythos Preview discovered high- and critical-severity flaws in essential software. Anthropic warns the industry must adapt to this volume.
Defending against the next generation of agentic AI attacks — Frontier AI models are compressing the attack lifecycle, enabling autonomous, adaptive threats faster than anything seen before.
The FBI wants ‘near real-time’ access to US license plate readers — A push for pervasive surveillance infrastructure with minimal oversight.
BambuStudio accused of violating PrusaSlicer AGPL license — Prusa’s Josef Prusa claims Bambu has been violating the open-source license since their fork.
