A clear reference of what Featherless CAN and CANNOT do
Featherless runs open-weight text-based LLMs via an OpenAI-compatible API. All models are hosted serverless — no GPU setup required. Below is a complete capability reference.
| Capability | Status | Example Models | Details |
|---|---|---|---|
| Text Generation | Supported | Qwen2.5-72B-Instruct, Llama-3.1-70B | General text completion and generation via /v1/completions and /v1/chat/completions |

| Vision / Image Analysis | Supported | Magistral-Small-2506, Qwen3-VL-30B, Gemma-3-27B | Image understanding, screenshot analysis via vision models (Mistral Small, Gemma 3, Qwen VL). See Vision AI for a dedicated playground. |
| OCR & Document Analysis | Supported | Mistral-Small-3.2, Qwen3-VL | Extract text from scanned documents, receipts, screenshots using vision models with OCR capabilities |
| Tool Calling / Function Calling | Supported | Qwen2.5-72B, Qwen2.5-7B-Tool | Models that can generate structured tool/function calls via the API |
| Reasoning & Chain-of-Thought | Supported | DeepSeek-R1-70B, OpenReasoning-32B | Models with explicit reasoning traces, thinking tokens, and step-by-step problem solving |
| Coding Assistance | Supported | Qwen2.5-Coder-32B, NextCoder-32B, Qwen3-Coder-480B | Code generation, debugging, explanation, and refactoring across many languages |

| Capability | Status | Recommended Alternatives | Details |
|---|---|---|---|
| Image Generation | Not Available | Stable Diffusion (via Automatic1111, ComfyUI), DALL-E 3, Midjourney, Flux | Featherless models are text-only. Image generation requires diffusion model architectures. |
| Video Generation | Not Available | Runway Gen-3, AnimateDiff, Kling AI, Sora | Video synthesis requires specialized temporal diffusion models with GPU clusters. |
| Audio / Speech / TTS | Not Available | ElevenLabs, Bark, XTTS-v2, Whisper (for STT) | Text-to-speech and audio generation use different model architectures (audio codecs, vocoders). |
| Image Editing / Inpainting | Not Available | ControlNet, Stable Inpainting, Photoshop AI, Clipdrop | Image editing requires spatial controls and diffusion models with masking capabilities. |
| Embeddings / Reranking | Not Available | Cohere Embed, OpenAI Embeddings, BGE, E5 | Embedding models produce vector representations, not text output. |
