Provider Setup Guides
Lenno supports multiple AI providers through a Bring Your Own Key (BYOK) model. Choose the provider and model that best fits your needs.
Supported Providers
| Provider | Models | Best For |
|---|---|---|
| Anthropic (Claude) | Claude Opus, Sonnet, Haiku | Complex reasoning, long context, coding |
| OpenAI | GPT-5.x Codex, GPT-4o, o3 | General purpose, vision, coding, reasoning |
| Mistral | Mistral Small/Large, Devstral | European hosting, multilingual, cost-effective |
These three providers have dedicated integrations with both a CLI execution mode and a direct API mode.
More Providers (API-only)
Beyond the three above, Lenno’s provider catalog includes a range of additional providers that connect via their OpenAI-compatible chat-completions API. Add any of them from your agent’s Provider tab the same way – paste an API key and pick a model:
| Provider | Example Models |
|---|---|
| DeepSeek | DeepSeek V3, DeepSeek R1 |
| xAI (Grok) | Grok 3, Grok 3 Mini |
| Cohere | Command A, Command R+ |
| Groq | Llama 3.3 70B, Mixtral 8x7B |
| Together AI | Open-source models (Llama, Qwen, etc.) |
| Fireworks AI | Open-source models |
| OpenRouter | Aggregated access to many models |
| Alibaba Cloud (Qwen) | Qwen models |
| Moonshot (Kimi) | Kimi models |
| Other (OpenAI-compatible) | Any custom endpoint that speaks the OpenAI chat-completions format |
How BYOK Works
- Get an API key from your chosen provider
- Add the key in your agent’s Provider tab
- Select a model from the available options
- Start using your agent – all AI calls use your key directly
You pay the provider directly at their published rates. Lenno does not add any markup or surcharge on AI usage.
Switching Providers
You can switch providers or models at any time without losing your agent’s personality, memory, or configuration. The provider only affects how responses are generated – everything else stays the same.
To switch, go to your agent’s Provider tab or use the /provider switch command.
