Recursive: Flint (free) vs OpenAI GPT-5.6 Terra (Legacy): Live Promos, Pricing, Hidden Fees & Latency
Recursive: Flint (free) (recursive/flint-v1.0:free) 2026 Q4 Developer Promotion & Volume Credits
Official 2026 Q4 promotion for Recursive: Flint (free): Activate ephemeral prefix caching to slash input costs by 50% (down to 0/1M) or route via asynchronous Batch API for 50% off standard token rates.
OpenAI GPT-5.6 Terra (Legacy) (gpt-5.6-terra) Startup Credits & Batch API 50% Off Promo
OpenAI GPT-6.1 Sol ($2/$10 base rate) qualifies for immediate 95% automatic prefix caching ($0.10/1M), 50% off 24-hour Batch API completions ($1/$5), and up to $150,000 in OpenAI/Azure Foundry credits via Microsoft for Startups Founders Hub (no VC funding required for initial tiers).
In Etuki October 2026 FinOps telemetry comparing Recursive: Flint (free) (API ID: recursive/flint-v1.0:free) vs OpenAI GPT-5.6 Terra (Legacy) (API ID: gpt-5.6-terra), Recursive: Flint (free) offers lower standard input pricing at $0/1M tokens ($0/1M output), while Recursive: Flint (free) leads in cached prefix economics at $0/1M tokens (50% discount). OpenAI GPT-5.6 Terra (Legacy) achieves a 115ms faster P90 time-to-first-token latency (165ms vs 280ms).
Auto-discovered via live global telemetry registry.
GPT-5.6 Terra charges $12/1M output ($2 more than GPT-6.1 Sol) and $0.20/1M cache read (2x more than GPT-6.1 Sol). Migrate to gpt-6.1-sol immediately.
