Models
AI models available in Foxl
Foxl supports models from multiple providers. Use Foxl relay credits, your own API keys (BYOK), or your ChatGPT Plus/Pro subscription (OAuth).
Foxl Relay Models
Included with your Foxl plan. No setup needed - just sign in and chat.
| Model | Provider | Context | Best For |
|---|---|---|---|
| Claude Opus 4.7 | Bedrock | 1M tokens | Most capable for complex reasoning + agentic coding |
| Claude Opus 4.6 | Bedrock | 1M tokens | Previous flagship; still 1M context |
| Claude Sonnet 4.6 | Bedrock | 1M tokens | Best balance of speed and quality |
| Claude Haiku 4.5 | Bedrock | 200K tokens | Fastest model, near-frontier intelligence |
| GLM 5 | Bedrock (Z.AI) | 200K tokens | Agentic coding, long-horizon tasks |
Subscription (OAuth) Models
Use your existing subscriptions. Desktop only - see Providers for setup. Foxl calls the vendor API directly with your OAuth token; tool use, adaptive thinking, and streaming all flow through Foxl's normal agent loop.
Claude Code (Anthropic Pro/Max)
| Model | Context | Best For |
|---|---|---|
| Opus 4.7 (Claude Code mode) | 1M tokens | Complex reasoning, coding, analysis |
| Sonnet 4.6 (Claude Code mode) | 1M tokens | Balanced speed and quality |
Claude Code (OAuth) runs in compatibility mode so requests route through your Claude Pro/Max subscription instead of pay-as-you-go "Extra usage". In this mode, Foxl-specific tools (memory, subagents, schedules, channel send, browser extension, view image) are disabled - only Bash, Read, Grep, and WebFetch are available. Haiku 4.5 is not exposed in this mode. For the full Foxl tool surface, use an Anthropic API key (BYOK) or the foxl.ai relay.
OpenAI (ChatGPT Plus/Pro)
| Model | Context | Best For |
|---|---|---|
| GPT-5.5 | 1M tokens | Latest frontier, reasoning + streaming |
| GPT-5.4 | 1M tokens | General-purpose reasoning |
| GPT-5.4 Mini | 400K tokens | Fast, cost-aware tasks |
| GPT-5.3 Codex | 400K tokens | Code-heavy tasks |
Also exposed as a built-in tool: gpt-image-2 via the generate_image tool. No API key, no per-image billing - powered by your ChatGPT Plus/Pro OAuth session. Accepts up to 10 input images for edit / compose mode.
Gemini CLI (Google)
| Model | Context | Best For |
|---|---|---|
| Gemini 2.5 Pro | 1M tokens | Long documents, deep analysis |
| Gemini 2.5 Flash | 1M tokens | Fast, cost-effective |

Adaptive Thinking
Claude Opus 4.7, Opus 4.6, and Sonnet 4.6 support adaptive thinking - Claude dynamically decides when and how much to think based on the complexity of your request. No manual budget setting needed.
- Simple questions: Claude responds directly without thinking overhead
- Complex problems: Claude automatically engages deep reasoning
- Agentic workflows: Claude can think between tool calls (interleaved thinking)
Adaptive thinking (type: "adaptive") is the recommended mode for Opus 4.7, Opus 4.6, and Sonnet 4.6. Haiku 4.5 uses type: "enabled" with a budget_tokens parameter instead.
Haiku 4.5 also supports extended thinking with type: "enabled" and budget_tokens.
You can toggle thinking on/off in the model selector.
Thinking and Cost
Thinking consumes output tokens. When thinking is enabled, the model may use 2-10x more output tokens depending on task complexity. This directly increases credit cost:
- Simple question without thinking: ~0.01 credits (Sonnet)
- Same question with thinking: ~0.05-0.15 credits (Sonnet)
- Complex reasoning with thinking: ~0.30-1.0 credits (Opus)
For cost-sensitive usage, disable thinking for simple tasks. For complex coding, analysis, or multi-step reasoning, thinking significantly improves quality and is worth the extra cost. See Credits for detailed per-token pricing.
Model Selection
Desktop App
Click the model name in the chat input area to switch models. Your selection persists across conversations.
Web App
Click the model selector dropdown to choose a different model. The selection is saved in your browser.
Bring Your Own Key (Desktop Only)
In the desktop app, you can use your own API keys instead of Foxl credits:

- Enter your API key
- Select a model from that provider
When using your own keys, no Foxl credits are consumed.
