Gemini Diffusion
Google DeepMind
Gemini Diffusion is our state-of-the-art research model exploring what diffusion means for language and text generation. Large-language models are the foundation of generative AI today. We’re using a technique called diffusion to explore a new kind of language model that gives users greater control, creativity, and speed in text generation. Diffusion models work differently. Instead of predicting text directly, they learn to generate outputs by refining noise, step by step. This means they can iterate on a solution very quickly and error correct during the generation process. This helps them excel at tasks like editing, including in the context of math and code. Generates entire blocks of tokens at once, meaning it responds more coherently to a user’s prompt than autoregressive models. Gemini Diffusion’s external benchmark performance is comparable to much larger models, whilst also being faster. -

Google Whisk is an AI-powered image generation tool from Google. Unlike traditional AI image generators that rely solely on text prompts, Whisk allows users to input images to define the subject, scene, and style of the desired output. Users can provide multiple images for each category and have the option to refine results further with text prompts. If users don't have specific images, Whisk can generate its own prompts to assist in the creation process. The tool emphasizes rapid visual exploration, generating images within seconds, and is built on Google's latest Imagen 3 model. While it may occasionally produce imperfect results, Whisk has been praised for its iterative and engaging approach to AI-driven image creation. -

Gemini Deep Research Max
Google
Gemini Deep Research is Google’s next-generation autonomous research agent, designed to plan, execute, and synthesize complex, multi-step research tasks across the web and private data sources into high-quality, structured outputs. Built on top of advanced Gemini models such as Gemini 3.1 Pro, it introduces a system where the AI can break down a user’s query into sub-tasks, search across multiple sources, evaluate relevance, and iteratively refine results before producing a comprehensive, cited report. It is positioned as a “step change” in long-horizon research workflows, enabling autonomous exploration of both public web content and custom enterprise data while maintaining context and coherence across extended reasoning chains. It supports features such as MCP (Model Context Protocol) integration, native visualizations, and significantly improved analytical quality, allowing users to generate insights.Starting Price: Free -

MetaPrompt
MetaPrompt
MetaPrompt is a tool within the Agent.ai ecosystem designed to help users build better, more effective AI prompts. It requires an Agent.ai account (free option available) and offers features such as saving and tracking prompt generations, private and secure storage of your work, and access to a suite of “AI-powered agents” that presumably assist with prompt construction, optimization, or management. The goal is to make prompt engineering easier, more reproducible, and more organized, helping users refine prompts over time using saved history. The core value appears to be enabling users to get more power and consistency out of their AI interactions by centralizing their prompts, tracking outputs, and improving prompt performance through iteration.Starting Price: Free -

Ray3.14
Luma AI
Ray3.14 is Luma AI’s most advanced generative video model, designed to deliver high-quality, production-ready video with native 1080p output while significantly improving speed, cost, and stability. It generates video up to four times faster and at roughly one-third the cost of its predecessor, offering better adherence to prompts and improved motion consistency across frames. The model natively supports 1080p across core workflows such as text-to-video, image-to-video, and video-to-video, eliminating the need for post-upscaling and making outputs suitable for broadcast, streaming, and digital delivery. Ray3.14 enhances temporal motion fidelity and visual stability, especially for animation and complex scenes, addressing artifacts like flicker and drift and enabling creative teams to iterate more quickly under real production timelines. It extends the reasoning-based video generation foundation of the earlier Ray3 model.Starting Price: $7.99 per month -

LLM Scout
LLM Scout
LLM Scout is an evaluation and analysis platform designed to help users benchmark, compare, and interpret the performance of large language models across diverse tasks, datasets, and real-world prompts within a unified environment. It enables side-by-side comparisons of models by measuring accuracy, reasoning, factuality, bias, safety, and other key metrics using customizable evaluation suites, curated benchmarks, and domain-specific tests. It supports the ingestion of user-provided data and queries so teams can assess how different models respond to their own real-world workflows or industry-specific needs, and visualize outputs in an intuitive dashboard that highlights performance trends, strengths, and weaknesses. LLM Scout also includes tools for analyzing token usage, latency, cost implications, and model behavior under varied conditions, helping stakeholders make informed decisions about which models best fit specific applications or quality requirements.Starting Price: $39.99 per month -

Hamming
Hamming
Prompt optimization, automated voice testing, monitoring, and more. Test your AI voice agent against 1000s of simulated users in minutes. AI voice agents are hard to get right. A small change in prompts, function call definitions or model providers can cause large changes in LLM outputs. We're the only end-to-end platform that supports you from development to production. You can store, manage, version, and keep your prompts synced with voice infra providers from Hamming. This is 1000x more efficient than testing your voice agents by hand. Use our prompt playground to test LLM outputs on a dataset of inputs. Our LLM judges the quality of generated outputs. Save 80% of manual prompt engineering effort. Go beyond passive monitoring. We actively track and score how users are using your AI app in production and flag cases that need your attention using LLM judges. Easily convert calls and traces into test cases and add them to your golden dataset. -

PromptSignal
PromptSignal
PromptSignal is an AI visibility analytics platform that monitors how major large language models like ChatGPT, Claude, Perplexity, and Gemini mention, rank, and describe brands. As consumers increasingly rely on AI assistants instead of search engines to research, compare, and evaluate products, PromptSignal helps companies understand and optimize how their brand appears in AI-generated answers. The platform provides daily monitoring across multiple models, offering visibility scores, ranking positions, sentiment analysis, and competitive benchmarks. It includes tailored prompt suggestions to test brand performance and actionable recommendations to improve positioning and perception in LLM responses. Metrics such as brand visibility, competitor tracking, sentiment score, ranking position, and prompt performance allow teams to track where their brand is winning or falling behind.Starting Price: $99 per month
