Strengths & weaknesses
Mistral
Stability AI
Key differentiators
The only frontier lab offering open-weight models alongside proprietary ones — giving teams the flexibility to self-host or use the API.
Stable Diffusion models are open-weight and can be self-hosted, making them the most flexible option for teams that need full control over their image generation pipeline.
Frequently asked questions
Mistral FAQs
How much does the Mistral API cost?
Mistral Large costs $2.00/1M input and $6.00/1M output tokens. Mistral Small is $0.10/$0.30 per 1M tokens — one of the cheapest capable models available. Codestral for code generation is priced separately.
Are Mistral models open-weight?
Some are. Mistral 7B, Mixtral 8x7B, and Mixtral 8x22B are open-weight and available on Hugging Face for self-hosting. Mistral Large and Codestral are proprietary and only available via the API.
What is Codestral?
Codestral is Mistral's code-specialised model with a 262K context window. It supports 80+ programming languages and is optimised for code completion, generation, and explanation tasks.
Stability AI FAQs
What is Stable Diffusion?
Stable Diffusion is an open-weight text-to-image model developed by Stability AI. It can be run locally or accessed via the Stability AI API, and has spawned a large ecosystem of fine-tuned variants.
How does Stability AI compare to DALL-E 3?
DALL-E 3 generally produces more photorealistic and instruction-following images out of the box. Stable Diffusion offers more flexibility through open weights, fine-tuning, and self-hosting.
