Who each one suits
ChatLLM

Worth knowing
ChatLLM
- There is no free plan or free trial. Billing is monthly at $10 per user, or $20 per user with Pro.
- Usage runs on credits: Basic has 20,000 a month, and heavy models, images, video and agent tasks use them faster. A set of lighter models stays unlimited.
- Basic limits the Abacus AI Agent to 3 tasks of limited complexity and Abacus AI Studio to 3 conversations. Pro removes both caps.
- Abacus.AI states that it does not give refunds based on the output or performance of its models and agents.
T3 Chat
- Prices and usage limits are shown only in the app's settings page and could not be read for this listing.
- Usage is metered: long threads, attachments, search and costlier models drain the quota faster, and when both buckets are empty you wait for a refill.
- The terms of service say no refunds are given when you cancel your account.
- The pages that could be read describe a web app only; no desktop or mobile apps are mentioned.
Key features
ChatLLM
- 100+ models with automatic routing
- Chat with models from OpenAI, Anthropic, Google, xAI and open-weight labs, or leave the picker on Auto and RouteLLM chooses a model for each task.
- Abacus AI Agent
- A general-purpose agent that builds and hosts apps from a description, creates slides, documents and research reports, and automates work with tasks and triggers.
- Image and video generation
- Image models include Nano Banana Pro, GPT Image and FLUX. Video generation runs through Abacus AI Studio with models such as Veo, Kling and Seedance.
- Documents, data and web search
- Analyzes uploaded PDFs, Word and PowerPoint files, charts data from CSV and Excel files, searches the web and runs generated code in a playground beside the chat.
- Team workspace and connectors
- Invite any number of users at the per-user price, organize chats and files in projects, and connect Slack, Microsoft Teams, Google Drive, SharePoint, Confluence and other systems.
- Mobile apps, extension and desktop tools
- iOS and Android apps with voice mode, a Chrome extension, and Abacus AI Desktop with a coding agent and CLI are included with the subscription.
T3 Chat
- Models from several providers
- Runs models from OpenAI, Anthropic and Google and routes others through OpenRouter. The model and its reasoning effort are chosen per chat.
- Web search
- Search can be switched on for a chat so that answers draw on more recent results, with between 1 and 5 search queries or tool calls allowed per run.
- Two-bucket usage meter
- Usage is spent from a Base bucket that refills every 4 hours, then from an Overage bucket that refills on the monthly renewal date. Settings show each as its own percentage bar.
- File and image attachments
- Prompts can include uploaded PDF files, images and text files. Large or numerous attachments raise what a message costs against the usage meter.
- Profiles and temporary chats
- A chat can be started under a named profile, or as a temporary chat that is not kept as a saved thread. A /new URL with query parameters presets the prompt, model and search setting.
- Training opt-outs
- T3 Chat says it does not train its own models and has opted out of training-data collection with its providers where possible. Models that require training are labeled.
