Abacus AI (ChatLLM)
A single $10/month subscription that gives access to the major market models (GPT 5.5, Opus 4.8, Gemini 3.1 Pro, Nano Banana Pro for images) plus an app builder: you describe the app you want in natural language and DeepAgent builds the front end, back end and logic. The typical use case seen in practice: a personal job hunting app assembled in one day (CV parsing, job scoring through a LinkedIn scraper wired via API, application tracking board).
Strengths
- A single $10/month subscription for GPT 5.5, Opus 4.8, Gemini 3.1 Pro and the image models, instead of one subscription per provider
- DeepAgent assembles a full app (front end, back end, logic) from a natural language description: within reach of a non-dev
- Proven recipe: a personalized job hunting app (CV parsing + job scoring + tracking) assembled in one day
Limitations
- Closed platform: your app lives at Abacus, not in a repo of your own; leaving means rebuilding everything
- The credit system (not tokens, variable conversion per model) makes real cost hard to predict under heavy use
- For serious production, a runtime you control (Claude Code + a Git repo) remains preferable
Best for
- A PM or designer who wants a working personal app (application tracking, internal tool) without writing code
- Someone who wants to compare the major market models under a single subscription before picking a side
