Pros and cons
GLM-5.2
Coding · freemium
Pros
- ✓MIT-licensed open weights — full commercial use, self-hosting, and fine-tuning with no revocable API terms
- ✓1M-token context handles whole codebases and long agent histories in one pass
- ✓Benchmark results competitive with top closed frontier models, especially on coding and agentic tasks
- ✓Genuinely free to start: chat UI, 20M signup tokens, or download the weights
- ✓Strong fit for coding agents thanks to its long-horizon, tool-use orientation
Cons
- ×At 744B parameters, self-hosting demands serious GPU hardware — out of reach for most individual developers
- ×Vendor-published benchmarks need independent verification; real-world coding performance may vary from the claims
- ×Hosted API and coding-plan pricing isn't transparently listed, so budgeting requires checking the site
- ×As a model from Zhipu AI, some enterprises face data-residency or procurement constraints around China-based providers
Aider
Coding · free
Pros
- ✓Completely open-source with an active community and frequent updates
- ✓Automatic git commits give a clean audit trail and easy rollback for every AI change
- ✓Works with any LLM — swap between Claude, GPT, Gemini, or local models freely
- ✓No IDE lock-in: use it alongside Vim, Emacs, VS Code, or anything else
Cons
- ×Terminal-only interface has a steep learning curve for non-CLI users
- ×Requires your own API keys — no turnkey experience like Cursor or Copilot
- ×No inline code completion or real-time suggestions; it's conversation-driven only
- ×Large codebases can burn through API tokens quickly with repo-map context
