xAI added a Grok Imagine Video 1.5 Lite tier to its Imagine API docs — 2 cents per second at 480p, 3 cents at 720p. The 720p price is one-fifth of the full version and under one-third of Kling 3.0 Turbo.
An never-announced model name appeared on OpenAI's API pricing page: gpt-rosalind-discovery. It sits next to gpt-rosalind-research under "life sciences models" at identical pricing. Nothing but a name and a price — no blog post, no docs, no system card. The use case can only be guessed from the name: most likely a new Rosalind-family member focused on drug discovery.
On October 7, Anthropic released Claude Haiku 5.5 — the third 5.5-family model in a month, aimed at high-frequency, low-cost tasks. Pricing is 75% cheaper than Haiku 4.5, matching OpenAI's GPT-6 Luna directly.
