Gemini 3.1 Pro
Gemini 3.1 Pro is the next-generation flagship multimodal model from Google, with a very long context window and top-tier reasoning and coding. Fully OpenAI-API compatible: set model to gemini-3.1-pro in your existing SDK. Low-reasoning tier by default (faster and cheaper); pass reasoning_effort=high for the high tier (billed at the Preview rate). Responses carry a reasoning_content field so you can see the thinking (streamed chunk by chunk as well).
Gemini 3.8 Flash
Gemini 3.8 Flash is the latest Flash generation from Google (released September 2026), built for long-running coding, agent workflows and complex reasoning: 1M-token context, up to 64K output, image input. It uses a dynamic thinking budget -- quick answers for simple questions, more thinking for hard ones. Fully OpenAI-API compatible: set model to gemini-3.8-flash.

Claude
Anthropic
Claude Opus 5.5
Claude Opus 5.5 is the newest model in Anthropic's Opus line and the successor to Claude Opus 5, built for long-horizon agentic coding and knowledge work: a 1M-token context window, up to 128K output tokens per request, and adaptive thinking that is always on. It supports image input, tool calling, prompt caching and streaming. NezhaGate serves it through both the OpenAI-compatible API and the native Anthropic Messages API (/anthropic), so Claude Code connects directly; the five effort levels (low to max), thinking summaries, structured output and PDF input are available on the native API. Pay as you go; failed calls are never billed.
Claude Sonnet 5.5
Claude Sonnet 5.5 is the newest model in Anthropic's Sonnet line and the successor to Claude Sonnet 5, which Anthropic calls its best combination of speed and intelligence: output more than 30% faster than Sonnet 5, fewer tokens and tool calls for the same task, and 70.6% on Terminal-Bench 4.0. It has a 1M-token context window, up to 128K output tokens per request and adaptive thinking, with image input, tool calling, prompt caching and streaming. NezhaGate serves it through both the OpenAI-compatible API and the native Anthropic Messages API (/anthropic), so Claude Code connects directly; effort control, thinking summaries, structured output and PDF input are available on the native API. Pay as you go; failed calls are never billed.
Claude Opus 5
Claude Opus 5 is the next-generation flagship from Anthropic, with adaptive thinking on by default. It excels at complex reasoning, code engineering and agent orchestration, and supports image understanding, tool use and prompt caching. Fully OpenAI-API compatible: set model to claude-opus-5; or use the native Anthropic Messages API so Claude Code connects directly.
Claude Fable 5
Claude Fable 5 belongs to the Anthropic Fable series: same generation and capability base as Opus 5 (adaptive thinking, tool use, image understanding, prompt caching), with a finer touch and richer emotional layering in Chinese narrative and long-form writing. Fully OpenAI-API compatible: set model to claude-fable-5; the native Anthropic Messages API is supported as well.
Claude Sonnet 4.6
Claude Sonnet 4.6 strikes an excellent balance between capability and speed, excelling at everyday chat, code and agents at a great price. Fully OpenAI-API compatible: set model to claude-sonnet-4-6 and you are connected.
