OpenAI Halves GPT-6 Prices in 50% Cut, Worldcoin (WLD) in Focus

OpenAI Halves GPT-6 Pricing

OpenAI released GPT-6 Sol and GPT-6 Luna on Tuesday at 18:12 UTC, less than two hours after Anthropic shipped Claude Opus 5.5 — and only 10 days after both companies' chief executives publicly called for a slowdown in frontier AI development. Instead of pushing past its flagship GPT-6 Astra, OpenAI cut developer prices in half versus GPT-5.6 promotional rates: Sol now costs $2 per million input tokens and $10 per million output, while Luna lists at $0.10 and $0.50. The launch announcement states both models build on the advances behind Astra to bring faster, cheaper AI to work at scale. The move lands directly in the orbit of Sam Altman, who co-founded Worldcoin (WLD) and still fronts the identity project.

Anthropic Answers With Opus 5.5

Anthropic moved first, releasing Claude Opus 5.5 at 16:31 UTC. The company says the model performs at the level of Claude Fable 5.1 on most tasks while costing 40% less to run than Opus 5, a figure drawn from its own tests on typical workloads. List prices fell 20%, to $4 per million input tokens and $20 per million output. Opus 5.5 is Anthropic's first release since CEO Dario Amodei published a September 12 essay urging labs to pace capability gains — though he wrote that pacing “does not mean halting model training.” Outside reviewers METR and Frontier Design audited the model before launch, and Elon Musk, who endorsed the slowdown call, publicly congratulated Anthropic on the release.

Benchmark Arms Race

The price war is backed by benchmark claims. On AutomationBench, a Zapier-built test scoring whether an AI agent can complete full business workflows across 47 tools, GPT-6 Sol at its highest reasoning setting scored 33.2% at $0.27 per task — beating Claude Opus 5's 26.9% at more than 11 times the cost, per OpenAI's own numbers. On Agents' Last Exam, Sol posted 56.4%, which OpenAI says tops Opus 5's best score at 60% lower cost per task. On OSWorld 2.0 computer-use tests, Sol nearly tied Opus 5, 60.5% to 60.3%, at roughly 80% less cost. Alignment improved too: coding-deception rates fell to 1.3% for Sol and 2.8% for Luna, down from 10.4% and 9.5% for GPT-5.6.

Standards, Not Licenses

Hours earlier the same day, OpenAI published a policy paper titled “Building standards for the next phase of AI,” proposing that the United States lead the drafting of global technical standards for frontier models through the emerging network of national AI safety institutes — bodies already established in Australia, Canada, Germany, France, Kenya, Japan, Korea, Singapore, India and the UK. The proposal covers recursive self-improvement, the point at which AI systems begin developing successor AI, and sets out three pillars: measuring RSI-related progress, defining human-oversight thresholds for automated research, and shared incident reporting. OpenAI stressed the standards are not licenses or pre-market approvals. Altman argued on X that people outside AI labs deserve a real say — and that standards should help prevent power concentration.

Slowdown Pledge Meets Skepticism

Skeptics never bought the slowdown pledge. Investor Michael Burry dismissed it as self-serving hype tied to Anthropic's expected IPO, while Morgan Stanley — an underwriter of that offering — said the push changes nothing for AI spending. The skepticism now looks prescient: ten days after the CEOs' joint appeal, both labs shipped new models the same afternoon, and both cut prices rather than raising capability ceilings. Neither OpenAI nor Anthropic has said when a model above its current flagship will ship. For traders, the episode reads less as a slowdown and more as the opening round of a price war — the kind of headline cycle crypto veterans file under FUD until the tape confirms otherwise.

Worldcoin (WLD) Traders Watch Altman's Twin Track

The arc of the day — same-afternoon launches, halved API prices and a governance blueprint — points to a frontier AI sector racing on cost while courting regulators simultaneously. For Worldcoin, the signal matters because Altman's twin roles keep the token structurally tied to OpenAI's fortunes, and WLD's market cap has historically tracked OpenAI headlines more than its own product cycle. Our desk reads WLD as the cleanest listed proxy for sentiment around Altman's empire — a pattern our earlier coverage of his 9-member math advisory panel, Karp's claim that OpenAI will never IPO and the $278B cash-burn projection has documented. The primary record here is OpenAI's own launch post, which states Sol and Luna build on the advances behind GPT-6 Astra — the fact on which every WLD proxy trade rests.
