Why This Is Good for Freelancers
Freelancers who build things with AI will feel this most. If you sell chatbots, automation work, or coding service, API cost eat your profit.
One small test from outside show Flash 1017 finish one task in only $0.0157. Same task cost $0.0577 with GPT-6.1 Sol and $0.0653 with Claude Sonnet 5.5. Gap is big. But test was small, only 56 runs, so take it like a hint, not full proof. Still direction is clear. DeepSeek is the cheap option and it keep getting better.
New Search API and Fetch API also help you. Now you can build one AI agent which search web and read pages, all with one cheap API key.
Things You Must Care About
No release is perfect. Some honest points:
All scores come from DeepSeek self. Every test number in this post is from DeepSeek own tests. No outside lab check them till now. Big companies always pick tests which look good for their model. So wait for outside reviews before you full trust these numbers.
Servers went down this week. Few days before, DeepSeek servers stop working for near 5 hours. Full offline. Cheap price bring too many users, and system come under pressure. So if you make client project on DeepSeek, keep one backup plan ready.
Privacy also think one time. DeepSeek is China company. If you work with private client data, first read their privacy policy. Free and cheap tool also need your trust.
How You Can Try It
Try karna is very easy:
- Go to DeepSeek website or install DeepSeek app on your phone.
- New model is already live. You not need change any setting.
- API users keep using same name “deepseek-flash”. New model is now running behind this name.
- Developers can download open weights from Hugging Face and run model on own machine.
Last Words
This is good news for every person who pay for AI. Same price. Better scores. Fast answers. And free app also get this upgrade.
DeepSeek is fighting price war with big US labs. For students and freelancers, this fight mean more power in less money. Only keep backup ready, and not believe every test number until outside people check the work.
