Shortlist map
Compare exact access routes.
A model name does not define the endpoint, quota, context cap or agent scaffold. Use this map to choose a pair, then open the focused comparison and test both on the same repository task.

|---|---|---|---|---|---|
| GLM 5.3 | Z.ai, this site and compatible providers | Long-horizon coding and agent tasks | Managed API | Text | Usage or plan |
| Kimi K3 | Moonshot AI and verified providers | Multimodal and broad-context workflows | Managed provider | Verify endpoint | Provider dependent |
| Qwen 3.8 | Qwen Studio and verified providers | Broad model ecosystem and multimodal evaluation | Provider or model dependent | Variant dependent | Provider dependent |
| DeepSeek V4 | DeepSeek API and verified providers | Cost-sensitive reasoning and coding | Managed provider | Verify endpoint | Usage based |
| GPT-5.6 Sol | OpenAI API and authorized providers | Frontier reasoning and the OpenAI ecosystem | Managed API | Model dependent | Usage / service tier |
| Claude Fable 5 | Anthropic and authorized providers | Frontier coding and the Anthropic ecosystem | Managed API | Model dependent | Usage based |

Read articleHow to use this library
Use comparisons as an evaluation plan.
These comparisons are designed to narrow a shortlist, not crown a permanent winner. Model behavior depends on the provider, agent harness, available tools and the exact repository task.
Match the setup
Use the same repository snapshot, instructions, permissions, retry budget and acceptance tests for both models.
Measure accepted work
Track passing tests, unnecessary changes, reviewer corrections, latency and total cost per completed task.
Date every conclusion
Model aliases, quotas, prices and product scaffolds change. Recheck primary sources before a purchasing decision.
Begin with two or three tasks your team completes often, plus one difficult edge case. Save the prompts, outputs and reviewer notes. If one model wins only after extra retries or a different tool scaffold, preserve that difference in the conclusion instead of flattening it into a score. The useful result is a dated deployment decision with a fallback, not a universal ranking.
