GPT-6 and Claude Haiku 5.5 launch same day in split OpenAI-Anthropic strategies
On Oct 7 in San Francisco, OpenAI and Anthropic announced releases minutes apart. OpenAI began a full rollout of GPT-6 and introduced Intelligent UI, which lets ChatGPT answer with charts, buttons, forms or small interactive tools instead of plain text; paid users get GPT-6 Sol while free and Go users get GPT-6 Luna. Anthropic released Claude Haiku 5.5, the third model in the Claude 5.5 family, priced at $0.10 per million input tokens and $0.50 per million output tokens for requests under 100,000 tokens — a 90% cut versus Haiku 4.5 — with five adjustable reasoning-effort levels. The article frames the split as OpenAI chasing the interaction entry point while Anthropic drives down per-task agent costs, citing OpenRouter data showing enterprise AI spend share shifted from roughly three-quarters for Anthropic early in the year to near parity.
Same-day launches point to two different bets — owning the AI interface versus owning the cheapest execution layer — as model capability commoditizes.
