The verdict
Pick GLM-5.2 if…
- →overall capability matters more than price (AI Score 8.7 vs 8.2)
- →you want our editor's pick for this category
- →your primary use case is development teams building coding agents who want a frontier-class model they can self-host, fine-tune, and deploy under a fully permissive license.
- →you need: development, agents

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
Codex Security CLI
Coding · free
Pros
- ✓Genuinely open source — you can read the client, audit its calls, fork it, and pin a version rather than trusting a black-box security vendor
- ✓Tracks findings across runs, so a scan reads as a delta instead of the same wall of unranked issues every build
- ✓Verifies that fixes actually closed the finding, which is what makes it viable as a CI gate rather than a report-only scanner
- ✓Model-based analysis can follow logic across files without someone first writing a rule for that specific pattern
- ✓Free at the tool layer, which puts real scanning in reach of teams shipping AI-generated code with no security budget
Cons
- ×Day-one release in early access — the command surface and flags will churn, so pin the version before it gates anything
- ×The client is open but the model that ranks a finding as critical or noise is not, and neither is the eval set behind it
- ×Same-vendor auditing: Codex writes the code and a Codex-branded tool grades it, with no public study of whether same-family generator and auditor share blind spots
- ×Whether your unpatched inventory stays on the runner or leaves it is worth establishing from the source before wiring this into a pipeline
