Cohere Command Light vs OpenAI GPT-5.6 Terra (Legacy): Live Promos, Pricing, Hidden Fees & Latency
Cohere Command Light (cohere-command-light) 2026 Q4 Developer Promotion & Volume Credits
Official 2026 Q4 promotion for Cohere Command Light: Activate ephemeral prefix caching to slash input costs by 95% (down to 0.2/1M) 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 Cohere Command Light (API ID: cohere-command-light) vs OpenAI GPT-5.6 Terra (Legacy) (API ID: gpt-5.6-terra), Cohere Command Light offers lower standard input pricing at $0.8/1M tokens ($3.2/1M output), while Cohere Command Light leads in cached prefix economics at $0.2/1M tokens (95% discount). Cohere Command Light achieves a 20ms faster P90 time-to-first-token latency (145ms vs 165ms).
Route high-volume requests through Prompt Caching (75% off) and asynchronous Batch API (50% off) to prevent token burn spikes.
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.
