LLM Pricing and Performance Briefing

This briefing summarizes recent information regarding large language model (LLM) pricing, performance, and strategic positioning. The focus is on API pricing and reported capabilities for coding and agentic workloads.

Gemini 3.7 Flash carries introductory API pricing. This model is positioned for coding and agent use cases. The stated rates are $0.75 input and $3.75 output per 1 million tokens. Google also lists Gemini 3.7 Flash in its agent platform pricing at these same introductory rates.

Claude Opus 4.6 maintains premium frontier pricing. This model is also positioned for coding and agent tasks. Its pricing is $5 input and $25 output per 1 million tokens. These Opus pricing figures are consistent across Anthropic’s news and product pages.

Grok 4.6 is priced as a more economical frontier option. A fast variant of Grok 4.6 is also available. Base pricing for Grok 4.6 is $2 input and $6 output per 1 million tokens. OpenRouter’s Grok 4.6 page confirms this base pricing and adds a cost for web-search calls: $5 per 1,000 calls.
