# Models

Pick a model per thread from the new-thread dialog, switch mid-thread with [`/model`](/docs/agent/slash-commands), or set a project-wide default under **Settings → Project → Agent**.

## Platform models

These are billed to your workspace's [credit ledger](/docs/billing):

| Model | Provider | Context window | Reasoning effort | Fast tier |
| --- | --- | --- | --- | --- |
| **GPT-5.6 Sol** | OpenAI | 200k | none → max | yes |
| **GPT-5.6 Terra** (default) | OpenAI | 200k | none → max | yes |
| **GPT-5.6 Luna** | OpenAI | 200k | none → max | yes |
| **GPT-5.5** | OpenAI | 200k | minimal → xhigh | yes |
| **GPT-5.3 Codex** | OpenAI | 400k | low → high | no |
| **Fable 5** | Anthropic | 200k | none → xhigh | no |
| **Opus 5** | Anthropic | 1M | none, low → max | no |
| **Opus 4.8** | Anthropic | 200k | none → xhigh | no |
| **Sonnet 4.6** | Anthropic | 200k | none → xhigh | no |
| **Haiku 4.5** | Anthropic | 200k | none → xhigh | no |

All platform models accept image input, so screenshots and design files in your messages reach the model directly.

## Reasoning effort

Reasoning effort trades latency and cost for depth: `none`, `minimal`, `low`, `medium` (the default), `high`, `xhigh`, and `max`. The picker only shows the levels the selected model actually supports. Reasoning tokens are billed as output tokens.

## Speed

Models with a fast tier (currently the GPT family) offer a **standard / fast** toggle. Fast maps to a priority service tier — same model, quicker output.

## Automatic ChatGPT / API routing

There is one model list—no separate `codex/` copies. If you connect ChatGPT under **Settings → Account → Profile → Connect ChatGPT**, supported OpenAI models automatically use that subscription and are **billed to your ChatGPT plan, not your workspace credits**. If no eligible connected subscription is available for the thread, Hoplite runs the same selected model through the platform API instead. Usage is still recorded on the [usage page](/docs/billing#usage), with the actual payer tracked per call.

## Housekeeping models

Small, fast delegate models handle background work like generating thread titles and context compaction — you don't pick these, and they keep housekeeping costs negligible.
