| Notes Flagship announced 2025-11 with 1M input / 64K output tokens. The Gemini API pricing page (checked 2026-08-10) lists only the 2.5/3.1/3.5/3.6 series and still shows no per-token price for Gemini 3. | ||||||||
| Gemini 3.5 Flash | Mid-tier | — | — | $1.50 | $9.00 | — | Source as of 2026-08-10 | |
| Notes Described in the model list as the most intelligent model for sustained frontier performance on agentic and coding tasks. It remains on the pricing page alongside the newer Gemini 3.6 Flash. Context window and release date are not listed. | ||||||||
| Gemini 3.6 Flash | Mid-tier | — | — | $1.50 | $7.50 | — | Source as of 2026-08-10 | |

| Notes Meta's first paid API coding model; pricing is not in Meta's official blog and comes from TechCrunch reporting, so treat with caution. | ||||||||
| Qwen3.8-Max | Alibaba | Flagship | 1M | — | $2.00 | $6.00 | 2026-08-03 | Source as of 2026-08-10 |
| Notes A 2.4T-parameter MoE with 95B active, announced as the first Qwen-Max-class model to get open weights. Price and context window are as listed on QwenCloud. Max output is left null: QwenCloud shows "131.1K" while a configuration example in the official blog lists maxTokens 65536, so no single figure could be confirmed. | ||||||||
