Welcome to the daily AI news brief for vibe coders. It is Tuesday, May 26, 2026. In the last 24 hours, Anthropic priced a $30B funding round at a $900B+ valuation, Andrej Karpathy returned to the LLM frontier as an Anthropic pretraining lead, Claude Code shipped session scoping and rewind compression, and a Gemini preview model hit its scheduled retirement. If you build on Shopify, Claude, GPT, Gemini, or Firebase, today is a budgeting day. Pricing leverage, model deprecation timelines, and tooling defaults all just shifted.
TL;DR
- Anthropic closes a $30B round at a $900B+ valuation; Q2 revenue guided to $10.9B.
- Andrej Karpathy joins Anthropic to rebuild the pretraining research team.
- Claude Code adds
claude agents --cwd, recent-session feedback, and rewind compression. - Gemini 3.1 Flash-Lite preview retires today (May 25 sunset). Migrate now.
- Anthropic reportedly signs a $45B compute deal with SpaceX through May 2029.
- Papal encyclical “Magnifica Humanitas” frames AI as a human-dignity issue.
Anthropic closes $30B round at $900B+ valuation [STACK]
What shipped. Reports describe Anthropic closing a roughly $30B financing round that values the company above $900B, ahead of OpenAI’s March valuation. Anthropic has also guided Q2 revenue to $10.9B and its first quarterly operating profit (llm-stats).
Why it matters for vibe coders. Pricing power for Claude models tracks revenue and capacity. A bigger balance sheet means more compute headroom, more aggressive context-window upgrades, and longer support windows for the Claude Agent SDK. It also means more bargaining power against GPU suppliers, which trickles into per-token pricing.
What to do today. Lock in your annual Claude usage forecast. If you are over $5K/month on the API, ask sales about volume commits before the next price reset.
Karpathy joins Anthropic to rebuild pretraining [STACK]
What shipped. Andrej Karpathy, OpenAI co-founder and former Tesla Autopilot lead, is joining Anthropic to rebuild its pretraining research team. He cites the next few years at the LLM frontier as especially formative (llm-stats).
Why it matters for vibe coders. Pretraining leadership signals research direction. Karpathy’s bias toward small, well-engineered systems and education-first artifacts is a leading indicator that Claude’s next base models prioritize coding, tool use, and long-horizon agent behavior — exactly what multi-agent builders rely on.
What to do today. Star the anthropics/claude-agent-sdk-python repo and subscribe to release notes. Capability changes will land in agent tooling before they hit marketing copy.
Claude Code adds session scoping, feedback history, rewind compression [STACK]
What shipped. Claude Code now supports claude agents --cwd <path> to scope the session list to a directory, /feedback can include sessions from the last 24 hours or 7 days, and the Rewind menu offers “Summarize up to here” to compress earlier context while keeping recent turns intact (Claude Code changelog).
Why it matters for vibe coders. Context bloat is the silent killer in long agent runs. Rewind summarization lets you keep a multi-hour Claude Code session productive without losing the early plan. Directory-scoped session listing keeps multi-repo work tidy.
What to do today. Update Claude Code. Try Rewind > Summarize on any session over an hour old and measure token usage before and after.
Gemini 3.1 Flash-Lite preview retires May 25 [STACK]
What shipped. Google’s gemini-3.1-flash-lite-preview model reached its scheduled shutdown on May 25, 2026. Requests now route to a supported successor or fail, depending on your SDK version (Gemini API release notes).
Why it matters for vibe coders. Firebase AI Logic apps and any GenKit flows pinning the preview model break silently. Cost models built against preview pricing also no longer apply. If you wired Gemini into a Firebase product or a multi-model router, today is the day to audit.
What to do today. Grep your codebase for gemini-3.1-flash-lite-preview. Move calls to gemini-3.5-flash or another current GA model, retest latency, and update cost monitors.
Anthropic-SpaceX compute pact reportedly worth $45B [ECOSYSTEM]
What shipped. Reports describe an Anthropic compute agreement with SpaceX running roughly $1.25B per month through May 2029 — a total around $45B for GPU capacity (llm-stats).
Why it matters for vibe coders. Capacity commitments at this scale signal Anthropic is building for sustained agent workloads, not bursty inference. Expect higher rate limits, more long-running task tolerance, and pricing structures that reward steady-state usage.
What to do today. If you have been throttled on multi-agent runs, retest at higher concurrency this week. The capacity story is getting better, not worse.
Also worth noting
- Pope Leo XIV released the encyclical “Magnifica Humanitas,” focused on human dignity in the AI era, presented alongside Anthropic co-founder Christopher Olah (llm-stats).
- OpenAI is reportedly preparing a confidential S-1 filing with the SEC; no public timeline has been disclosed (llm-stats).
Build of the day
Ship a Claude Code agent that audits a repo for retired model strings. Two hours. Use Claude Code with claude agents --cwd scoped to one project. Add an MCP tool that runs ripgrep for known-deprecated identifiers (gemini-3.1-flash-lite-preview, gpt-5.3-instant, etc.). Pipe matches into a Markdown report with file, line, and a suggested replacement. Run Rewind > Summarize before you ask Claude to write the PR description so token use stays low.
FAQ
Is Anthropic worth more than OpenAI now?
Recent reports put Anthropic’s funding round at a $900B+ valuation, above OpenAI’s March valuation. Valuations move with each round and secondary-market trade, so the lead can flip again on the next print. The structural story for builders is that both companies have enough capital to keep frontier training going at scale through 2027 (llm-stats).
How does the SpaceX compute deal affect Claude pricing?
A $45B capacity commitment through May 2029 suggests Anthropic is buying enough GPU time to support sustained agent workloads. That tends to push API prices down at the high-volume tier and lift rate limits. It does not guarantee lower retail per-token prices on the consumer Claude plans (llm-stats).
What should I do if my app uses gemini-3.1-flash-lite-preview?
Migrate today. The preview model retired May 25, 2026. Replace the model identifier with a current GA Gemini Flash model in your Firebase AI Logic or GenKit code, retest latency and output quality, and update any cost dashboards that were calibrated against preview pricing (Gemini API release notes).
What is the new Claude Code rewind compression feature?
Rewind > “Summarize up to here” compresses earlier turns in a Claude Code session into a concise summary while leaving recent turns intact. The goal is to keep long sessions productive without burning the context window. Combined with claude agents --cwd, it makes multi-hour repo work practical (Claude Code changelog).
Does Karpathy’s move to Anthropic change Claude’s roadmap?
It signals priorities. Karpathy’s public work has emphasized small, well-engineered systems and reproducible tooling. His leading the pretraining team is a strong indicator that Claude’s next base models keep prioritizing coding, agent loops, and long-horizon tool use — the capabilities multi-agent builders depend on most (llm-stats).
How should a Shopify builder react to today’s news?
Audit your agent stack. Pin Claude model versions in production, migrate off the retired Gemini preview model, and update Claude Code locally. If you sell on Shopify, watch for Agentic Storefront and Universal Commerce Protocol updates — capacity and pricing trends from Anthropic and Google are tailwinds for agentic commerce (llm-stats).
