When to choose each
DeepSeek-V4-Pro
Best for
- Agentic coding and terminal tasks
- Long-context jobs that need very long outputs
Watch out for
- The recorded rates are peak-hour prices (01:00 to 04:00 and 06:00 to 10:00 UTC on weekdays)
- No image input on the DeepSeek API, where the cheaper deepseek-flash has it
- DeepSeek had planned to retire it in September before extending service, so check its status before a long commitment
Muse Glimmer
Best for
- Local or on-device coding agents on a single GPU
- Fine-tuning an Apache 2.0 multimodal base
Watch out for
- Self-hosted only: Meta does not serve it over its Model API, so there is no first-party per-token price
- Audio is not supported and video is read as individual frames; the default context is 128K tokens
