Dropstone 1.5 is our monthly re-baseline release. We test the top AI coding models every month and rebuild the runtime on whichever wins. This month: DeepSeek V4 Flash, V4 Pro, and Moonshot Kimi K2.6 all hosted in the US, nothing stored on our side. $15/month gets you about 450 deep coding sessions a week. Roughly twice what Claude Code Pro delivers at $20. Full technical report with the cost math and benchmarks: blankline.org/research/dropstone-1-5
Dropstone 1.5 is the first release from our new monthly cycle. Every month my team at Blankline tests the strongest open AI coding models, rebuilds the runtime around whichever wins, and ships.
This cycle we focused on two things. Cost, and safety.
On cost. Dropstone Pro and Heavy 1.5 run on trillion-parameter class open-weight models, the same scale that closed labs like Anthropic charge a premium for. We spent the month measuring what each coding session actually costs us, then squeezing it. $15 a month gets you about 450 deep coding sessions a week. Claude Code Pro gives you 150 to 225 for $20. On capability, Dropstone Pro 1.5 trades blows with Claude Opus 4.7. We match or beat it on most other coding work at a fraction of the price.
On safety. We built Dropstone safe enough to use on our own internal codebase first. Every file write, every shell command, every network call asks before it runs. Everything runs on US servers. Nothing is stored anywhere. That same safety boundary ships to every tier, Free, Pro, and Heavy. Using DeepSeek or Kimi through Dropstone is meaningfully safer than reaching for them directly.

Who hunted Dropstone 1.5?
Dropstone 1.5 was hunted by Santosh Arron. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
