What each model is for
Gemini 3.6 Flash
Google · Balanced
Google's current workhorse model, released July 2026 as the practical successor to 3.5 Flash rather than the long-delayed 3.5 Pro. It improves on coding, knowledge work and multimodal handling while reducing token usage by up to 17%, which makes it cheaper to run than its predecessor on the same task even before the headline rate is compared.
- Up to 17% fewer tokens per task than 3.5 Flash
- Coding and knowledge work
- Multimodal input including audio and video
- 1M-token context
DeepSeek-V4-Flash
DeepSeek · Efficient
The public-beta release of DeepSeek V4 Flash, which supersedes the earlier preview with substantially stronger agentic behaviour; DeepSeek reports its agent scores beating the larger V4-Pro-Preview. Its defining feature is the price/capability ratio: a 1M-token context window at a fraction of frontier rates. The listed price is DeepSeek's cache-miss rate; cache hits bill lower.
- Very low cost for a 1M-context model
- Agentic task performance
- Long-context handling
- Cheaper cache-hit pricing
