+## GPT-6 Sol and Luna
+
+GPT-6 Sol (`gpt-6-sol`) and GPT-6 Luna (`gpt-6-luna`) are available through this provider for ChatGPT Plus, Pro, Business, Enterprise, and Edu accounts. Select either model after signing in; availability remains controlled by OpenAI for the signed-in account.
+
+Both models support image input and reasoning effort levels from `none` through `max` (Zoo Code defaults to `medium`). For the upstream rollout and model contracts, see OpenAI's [GPT-6 Sol](https://developers.openai.com/api/docs/models/gpt-6-sol) and [GPT-6 Luna](https://developers.openai.com/api/docs/models/gpt-6-luna) model pages.

+GPT-6 Sol (`gpt-6-sol`) and GPT-6 Luna (`gpt-6-luna`) are OpenAI's cost-efficient GPT-6 models, announced on September 22, 2026 at roughly half the API price of their GPT-5.6 counterparts. Both support text and image input, a 1,050,000-token context window, up to 128,000 output tokens, and reasoning effort levels from `none` through `max`. Prompts above 272,000 input tokens use long-context pricing, cached input reads are discounted by 90%, and Flex and Batch are priced at 50% of standard rates.

+For the complete, up-to-date model list and capabilities, see [OpenAI's models documentation](https://platform.openai.com/docs/models) and the [GPT-6 Sol](https://developers.openai.com/api/docs/models/gpt-6-sol) and [GPT-6 Luna](https://developers.openai.com/api/docs/models/gpt-6-luna) model pages.
+
+OpenRouter, Vercel AI Gateway, and NanoGPT also list `gpt-6-sol` and `gpt-6-luna` in their live model catalogs at OpenAI's standard rates, and Zoo Code discovers them dynamically through those providers. OpenCode Go does not currently list the GPT-6 models.

+For models that support reasoning (GPT-6, GPT-5, o1, o3, o4 families), you can control how deeply the model thinks:
+
+**GPT-6 Sol/Luna Models:**
+- `none` - Fastest responses without explicit reasoning
+- `low` - Quick responses with light reasoning
+- `medium` (default) - Balanced reasoning and response time
+- `high` - Deep reasoning for complex problems
+- `xhigh` - Extended reasoning for demanding problems
+- `max` - Maximum reasoning depth
 
 **GPT-5 Models:**
 - `minimal` - Fastest responses with basic reasoning
