Step 5 Preview is StepFun’s flagship AI model for agentic software engineering, professional knowledge work, and finance-oriented tasks. It supports vision input and a 1M-token context window, and is available through StepFun products and API.
NVIDIA Nemotron 3.5 Super VL is an open, customizable multimodal model for developers building specialized AI agents. It combines reasoning, tool use, and understanding of text, images, documents, and video, with support for post-training through NVIDIA NeMo.
Muse Spark Open is a Meta vision-language model on Hugging Face that combines an image with a text prompt to generate a textual response. It is intended for visual question answering, image description, multimodal assistant workflows, and permitted model adaptation, subject to its license and Usage Policy.
Navige is an AI agent and LLM cost-optimization layer for teams that want to reduce unnecessary model spend without changing their existing prompts, workflows, or tool schemas. It routes calls, limits repeated work, and offers free monitoring through weekly Watchtower reports.
KernelAI is a mobile AI app that runs 53 open-weight models locally on iPhone, iPad, and Android devices. It helps users chat, work with documents and images, code, and use AI offline without an account or subscription.
Microsoft-Decision-1 is a decision-scoring AI model for structured outputs used in routing, classification, prioritization, verification, and workflow control. It is documented as available through Microsoft Foundry and OpenRouter.
iwant is an open-source CLI for launching open-weight language models on bare-metal GPUs in your own Google Cloud account. It provisions model-specific infrastructure and returns an OpenAI-compatible endpoint for applications and direct API requests.
Gemini platform is Google Cloud’s platform for developers, data scientists, and ML engineers to build, customize, deploy, govern, and optimize enterprise AI agents and generative AI applications. It includes model and agent development tools, enterprise-data grounding through Agent Search, and MLOps services.
Liquid Inference is an AI inference router that sends each LLM request to the lowest-priced provider meeting selected model, region, speed, and quality rules. It helps developers and teams manage provider choice, compatibility, and inference costs through OpenAI- and Anthropic-compatible APIs.
Mistral AI is an online AI service accessed through a browser-based account portal. The supplied page supports email-based login or signup and includes password recovery, but does not document the platform’s broader AI features or pricing.
FastRouter.ai is an OpenAI-compatible API gateway that gives AI teams unified access to more than 200 models across providers. It adds routing, failover, governance, observability, and weekly traffic-based savings recommendations for operating model workloads.
Gemini 4 Argon is Google’s frontier AI model for long-horizon software engineering, enterprise knowledge work and cybersecurity defense. It is initially rolling out to trusted cyber defenders, with broader access planned after further testing and guardrail development.
Hopscotch is a developer API gateway that provides access to 500+ AI models from multiple providers through one interface. It helps teams switch models, configure fallbacks, monitor usage, and control spending by key, teammate, and workspace.
Claude Sonnet 5.5 is Anthropic's AI model for well-scoped coding, knowledge work, document creation, spreadsheets, and computer-interface tasks. It is designed for users who need faster iteration and lower per-task costs than Claude Sonnet 5, while more complex open-ended work may be better suited to Claude Opus 5.5.
Cuey is a Chrome extension that runs prompts across multiple AI models and displays their answers side by side in a browser sidebar. It helps people compare responses, spot disagreements or omissions, and carry context across supported AI tools without API keys or an initial account.
Promptic is a GenAI optimization platform for developers and teams building LLM applications. It benchmarks prompts, models, and agent workflows on user-provided data, using quality, cost, and latency metrics to guide optimization and validation.
Claude Opus 5.5 is Anthropic’s Claude 5.5 model for complex agentic coding, computer use, knowledge work, and business workflows. It is designed for demanding multi-step tasks with lower reported typical workload costs and faster output than Opus 5.
Grok 4.7 is an xAI model for software development and knowledge work, including extended coding tasks and professional analysis. It is available through Grok Build, Cursor, the Grok API, and other developer platforms, with token pricing starting at $2 per million input tokens and $6 per million output tokens.
Twigg is a stateful HTTP API that stores LLM conversations, assembles context for the selected model, and routes requests across supported providers. It helps developers build persistent chat and tool-using applications without resending transcripts or locking a conversation to one model.
Gemini 3.8 Live and Gemini 3.8 Live Extended Thinking are Google voice-dialogue models for near-real-time conversation, visual context, tool use, and reasoning. They support developers and enterprises building voice agents, as well as live experiences across Gemini, Workspace, and Search.
