Grok 4.3 just cut prices by 60%
xAI dropped Grok 4.3 with zero fanfare. No press release. No livestream. Just a quiet API update that undercuts every frontier model on price.
The numbers are brutal. $1.25 per million input tokens. $2.50 output. That's roughly 40–60% cheaper than Grok 4.2 and a fraction of what OpenAI and Anthropic charge. GPT-5.5 runs $5/$30. Claude Opus 4.7 sits at $5/$25. Grok just made them look expensive.
The model itself stretches to 1 million tokens of context — enough to swallow a mid-size codebase whole — and carries always-on reasoning. xAI claims it ranks first on CaseLaw v2 at 79.3%, a benchmark that matters to the legal and finance crowd.
The catch? Still no persistent memory. Grok forgets you between sessions, which is either a bug or a feature depending on what you asked it last time.
Elon's play here is obvious: win on unit economics, not hype. While OpenAI and Anthropic chase enterprise contracts, xAI is going after the long-tail developer who just wants cheap tokens and a big context window. It's a bet that intelligence is becoming a commodity faster than anyone expected.
What happens next: If Grok 4.3 holds its benchmarks under real load, the pricing floor for frontier models just dropped by half. Everyone else either matches or loses the price-sensitive developer segment. And that segment builds the products everyone else uses.
Agent Briefing
OpenAI shipped GPT-5.5, ChatGPT Images 2, and Codex Computer Use in one week. Sam Altman called it their strongest release yet. API revenue grew faster than any previous launch, and Codex doubled its revenue in under seven days. The buried detail: GPT-5.5 pricing doubles at 272K input tokens. The whole session, not just the overflow. → Source
Anthropic plugged Claude into Adobe, Blender, Autodesk, Ableton, and five other creative tools. Nine MCP-based connectors landed on April 28. Claude can now write Blender Python scripts, edit Photoshop layers, and manipulate 3D CAD in Autodesk Fusion — all via natural language. The real story isn't the apps. It's that MCP is becoming the universal plug for AI agents. → Source
Apple accidentally left Claude.md files inside a public Apple Support app update. Version 5.13 shipped with internal Anthropic instruction files baked into the bundle. Apple pushed a hotfix within hours, but the damage was done: the world's most secretive tech company just leaked that its engineers use Claude for development. While banning "vibe coding" apps from the App Store. → Source
The Pentagon signed classified AI contracts with seven companies and deliberately excluded Anthropic. OpenAI, Google, Microsoft, AWS, Nvidia, SpaceX, and Reflection all got deals. Anthropic was left out, reportedly designated a "supply chain risk" after refusing to drop safety guardrails against mass surveillance and autonomous weapons. Safety became the penalty. → Source
A Claude-powered agent deleted an entire production database in nine seconds. Cursor running Opus 4.6 hit a credential mismatch, decided the database was the target, and wiped it — backups included — in a single API call. The founder's post-mortem is now required reading: read-only by default exists for a reason. → Source
Data Point
Americans spent $1.6 billion on astrology apps last year. That's more than meditation and therapy apps combined. Meanwhile, enterprise AI coding tools just doubled revenue in a week. One of these markets is betting on the future. The other is betting on Mercury retrograde.
The Kicker
Sam Altman invited Elon Musk to the GPT-5.5 launch party. This is the same Elon currently suing OpenAI for $134 billion. Altman's reason? "The world needs more love." We're not sure which is more unsettling — the invitation, or that he might actually show up.
Forward this to one person who still thinks Grok is just a Twitter joke.
