Two new flagship reasoning models are now available in our LLM model pickers: OpenAI's GPT-6 Astra and Anthropic's Claude Opus 5.5.
GPT-6 Astra
GPT-6 Astra (gpt-6-astra) is OpenAI's newest and most capable flagship, built for the hardest end-to-end work: complex reasoning, coding, and research.
- Available wherever you pick a text/reasoning model (static ads, carousels, rich media, video playgrounds, and more).
- Pricing: $10 / 1M input tokens and $50 / 1M output tokens.
- Static ads and carousels use a new top model tier for GPT-6 Astra.
Claude Opus 5.5
Claude Opus 5.5 (claude-opus-5-5) is Anthropic's latest flagship for deep reasoning, agentic workflows, and long-form polish.
- Replaces Claude Opus 5 and Opus 4.8 in the model pickers. Saved selections on those models (regenerations, restored briefs, campaign slots) keep working and show as Legacy in the picker until you switch.
- Default reasoning model for freeform / Hyperframes playgrounds.
- Pricing: $4 / 1M input tokens and $20 / 1M output tokens (lower than Opus 5).
