ChatLLM gives access to 20+ frontier models, including GPT-5.5, Claude Opus 4.8, Gemini 3.1 Pro, Grok 4.3, and DeepSeek v4.
It costs $10 per user per month, with image generation, video, agents, and a coding CLI included.
Reviewers praise the value but flag a clunky interface and coding that can be hit or miss.
If you pay for ChatGPT, Claude, and Gemini separately, the bill climbs fast. ChatLLM by Abacus AI pitches itself as the fix: one login, one flat fee, and access to nearly every major AI model at once.
What you actually get

ChatLLM bundles state-of-the-art LLMs like GPT-5.5, Codex 5.3, Claude Sonnet 4.6 and Opus 4.8, Gemini 3.1 Pro, Grok 4.3, Qwen 3.7 Max, DeepSeek v4, and Kimi 2.7, plus 20 more closed and open models.
For images you get Nano Banana Pro, Grok Imagine, and Flux Ultra, and video runs through Abacus Studio with Sora 2, Veo 3.1, Kling AI v3, and Seedance 2.0. A built-in router called RouteLLM picks the model for each task, so you skip the manual switching.
Beyond chat
This is where Abacus leans into its bigger claims. ChatLLM adds an Abacus AI Agent and a coding agent (CLI) that can vibe code apps, build presentations, run deep research, and automate workflows. The platform also markets CoWork and a SuperComputer for running cloud services, and bills itself as the world's first AI super assistant.
The price
A subscription is $10 per user per month, billed when you sign up, cancel anytime. A Pro tier adds $10 for unrestricted Agent and Studio access, and Enterprise starts at $5,000 a month. Abacus says it does not train on your data, encrypts everything, and holds SOC-2 Type 2 and HIPAA compliance.
The honest part
The Instagram pitch says the coding agent beats Claude and GPT-Codex. That is Abacus marketing, not a settled fact. Independent reviewers say the coding features can be hit or miss, and that serious developers may still want GitHub Copilot alongside it.
The bigger trade-off: you get the models, not the platforms, so there is no GPT Store, no Claude Projects, and no Canvas. The interface also gets called clunky and less polished than ChatGPT.
For freelancers and small teams drowning in three or four AI subscriptions, the math is hard to argue with. For someone who lives inside one tool's ecosystem, it is more of a sideways move than an upgrade.
