DeepSeek Deepseek Coder V2 Lite Instruct vs OpenAI GPT-5.6 Terra (Legacy): Live Promos, Pricing, Hidden Fees & Latency
DeepSeek Deepseek Coder V2 Lite Instruct (deepseek/deepseek-coder-v2-lite-instruct) — Automatic Disk KV Cache (0.004/1M) & Off-Peak Promo
DeepSeek-V4 Pro (1.6T MoE) automatically caches repeated 64-token prompt prefixes on NVMe storage at $0.022/1M off-peak input tokens (vs $0.66 off-peak base) with zero code changes required, plus off-peak UTC scheduling discounts.
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 DeepSeek Deepseek Coder V2 Lite Instruct (API ID: deepseek/deepseek-coder-v2-lite-instruct) vs OpenAI GPT-5.6 Terra (Legacy) (API ID: gpt-5.6-terra), DeepSeek Deepseek Coder V2 Lite Instruct offers lower standard input pricing at $0.04/1M tokens ($0.12/1M output), while DeepSeek Deepseek Coder V2 Lite Instruct leads in cached prefix economics at $0.004/1M tokens (90% discount). OpenAI GPT-5.6 Terra (Legacy) achieves a 30ms faster P90 time-to-first-token latency (165ms vs 195ms).
Gateway-synced rate ($0.04/$0.12 per 1M, flat 128K window). Verify upstream provider cache TTL and regional routing before high-volume batch runs.
Flat context pricing ($2.00/$12.00, Cache $0.20/1M); consider migrating to GPT-6.1 Sol ($2.00/$10.00, Cache $0.10/1M) for 95% cache savings.
