DeepSeek Pro and Flash continue to be extremely underrated.
Both are excellent choices for easy agentic loops
20x cheaper than GPT 5.5 and just as good
DeepSeek v4 works fine, but it’s not the frontier-pressing moment we saw with Kimi 2.6. On Notion eval data, it’s similar performance to GPT 5.2, with understandable failings.
Most interesting — it doesn’t scale well. It’s ridiculously slow. On multiple major, trusted, and performant US inference providers we see it 15x slower than GPT 5.2 and 2x slower than Opus 4.7, a problem Kimi never had.
Curious if it’s a fundamental issue in architecture, or a matter of time til inference providers make it work. Doesn’t seem urgent either way, if Kimi can outperform. Cheaper maybe, but not groundbreaking.
DeepSeek V4 Pro and Flash now available in Go
We rushed to get this released, still working out the capacity and usage limits
