An open-source Figma design system for rich LLM conversational interfaces
A large library of ready-made building blocks for conversational interfaces, plus screens you can customise to match your product.
Chat bubbles, sidebars with adjustable settings, prompt boxes and dedicated multi-prompt workflow screens cover the core chat patterns.
Override colors, spacing and typography through Figma variables and styles to match a brand system without rebuilding components.
A pre-designed dark theme is included, so you do not have to rework every screen for dark mode.

Enterprise developer platform and API for deploying GPT-6 Astra, Sol, Luna, and realtime multimodal agents.
Spanning GPT-6 Astra ($10/$50 per MTok), GPT-6.1 Sol ($2/$10), GPT-6.1 Terra ($1/$5), and GPT-6 Luna ($0.10/$0.50), all with a 1,050,000-token context window and 128K max output.
Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.
Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.
Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.

#1
Provides direct API access to Google's Gemini models with generous free prototyping tiers, but lacks OpenAI's ecosystem breadth.
#2
Free / Open-sourceAlibaba Cloud's 4th-generation multimodal AI assistant and foundation model lineup (Qwen4-Max, Qwen4-Plus, Qwen4-Flash & open-weight Qwen4-27B) with 1M context.

Unifies hundreds of third-party models under a single API key, offering greater model choice than OpenAI's curated catalog.
Free / Open-sourceRun and build with open AI models locally or in the cloud

Provides developer APIs for Zhipu AI's proprietary GLM models, serving as an alternative enterprise foundation model stack.

SpecialistOptimized for lightning-fast serverless execution of generative media and image models, rather than general text LLMs.

Specializes in high-performance serverless inference and dedicated GPU clusters for open-source models, bypassing closed commercial restrictions.

SpecialistFocuses heavily on running and fine-tuning open-source vision and language models via simple APIs, unlike OpenAI's hosted closed models.

Free / Open-sourceSelf-hosted AI workspace for local and cloud models
One OpenAI-compatible API for 500+ image, video, audio, and LLM models

From idea or sketch to editable wireframes, hi-fi UI and code in minutes
