A Review of Eleven Models and Their Positions

Gemini 3.7 Flash was released with API pricing and a focus on coding and agent workflows. The pricing was listed at $0.75 input and $3.75 output per 1M tokens. This model included a 1,048,576-token context window.

Claude Opus 5 maintained a high position on coding-agent benchmarks. It achieved 89.1% on Terminal-Bench 2.1.

GPT-5.6 Sol surpassed Claude Opus 5 on the same benchmark. It registered 89.5% on Terminal-Bench 2.1. GPT-5.6 Sol was also used to establish pricing comparisons for ChatGPT/Codex, with ChatGPT Plus via Codex noted at $20/month.

Grok 4.6 was positioned for long-running agents and interactive or visual tasks. No verified benchmark was available in the source for this claim.

ChatGPT GPT-5.6 Sol experienced reported price reductions in late August. The new pricing was $4 per 1M tokens for input and $20 per 1M tokens for output.

DeepSeek V4 Pro launched with competitive API pricing and claims related to agent capabilities. Its pricing was $0.435 input and $0.87 output per 1M tokens. It showed a 2.8% average gap on 9 tasks.

Tencent Hy4 was reported as an open-sourced flagship model with 770B parameters.

Qwen3.8-Flash was described as an open-weight multimodal MoE preview. Its specifications included 125B total parameters and 51B N-gram. API prices were stated as $0.16 input and $0.47 output per 1M tokens.

Chinese open-model activity was a significant factor in open-weight releases during summer 2026. This period saw 178 releases with over 20B parameters, with 59% licensed under Apache 2.0 and 22% under MIT.

Chinese monthly open-model parameter ceilings reportedly surpassed those in the U.S. for most of 2026. The monthly ceilings ranged from 754B to 2.78T parameters.
