- Instagram: migrate /v1/ to /v2/ ScrapeCreators endpoint (v1 deprecated Feb 2026) - OpenAI: switch fallback chain to [gpt-5-mini, gpt-4.1-mini, gpt-4.1] (8x cheaper, gpt-5-mini is the first mini model supporting web_search with filters.allowed_domains) - xAI: use explicit grok-4-1-fast-non-reasoning (bare name aliases to reasoning variant) - xAI: pass from_date/to_date natively to x_search tool config instead of prompt-only - Polymarket: correct rate limit comment (15K/10s, not 350/10s)
