DigitalOcean Ships Managed Agents as "Jev" Decision Models Spread Through the Dev Tooling Stack
DigitalOcean launched Managed Agents into public preview with per-second CPU billing and a gateway to 16,000+ governed tools, while @AndrewCurran_ claimed RSI could arrive by next summer, quoting Terence Tao's recent call to slow down. The day's biggest cluster, though, is the fast-growing "Jev" decision-model ecosystem, which gained vLLM support, a free open-source trial week, and a 20-item skills list.
Quick Hits
- @jenukal announced DigitalOcean Managed Agents in public preview: Firecracker microVM per session, an Action Gateway to 16,000+ governed tools, and per-second active CPU billing that he says cuts a typical agent run from $0.126 to about $0.031.
- @AndrewCurran_ argues "RSI isn't two years out. It's not even a year away" and predicts "the real thing by next summer," leaning on quotes he attributes to Terence Tao urging the field to slow down.
- OpenCode shipped v2.0.0 (@OpenCodeLog): a durable-inbox session core, sandboxed Code Mode tool execution, and SSH remoting plus an embedded Chromium pane in the desktop app.
- Decision-model plumbing keeps spreading: @vllm_project added DiffusionGemma-Jev support, @Hacubu is serving open-source SemIf free for a week, and @FareaNFts catalogued 20 Jev skills.
- Rumor to track: @ciruai amplifies a claim from @Biggest that a Qwen4-35B-A3B is being tested, though nothing has been announced.
DigitalOcean's bet: meter the work, not the VM
Vinay Kumar (@jenukal) posted the launch of Managed Agents, framing it around a shift in the cloud's "atomic unit" from the hourly VM to the agent. Each session runs in its own Firecracker microVM with pause, resume, checkpoint, and fork, and you can bring Claude Code, Codex CLI, OpenCode, Hermes, or a custom image. The Action Gateway exposes 16,000+ governed tools through one endpoint where "the agent never sees the key." The pricing claim is the notable part: active CPU billed by the second, with an hour of agent work that he says costs $0.126 fully allocated running about $0.031 at a typical 25% duty cycle, and zero while the agent waits. His diagnosis of the current stack is vendor sprawl, founders stitching together harnesses, sandboxes, inference, storage, and search across six vendors with "fifteen seams to secure and operate."
"The only way out is through": timeline warnings harden
The day's most charged post is @AndrewCurran_ replying to @willdepue, who wrote that people haven't internalized that "there'll soon be a machine better than us in every single intellectual & physical capacity." Curran insists he takes no lab money and posts to warn, then quotes Tao calling o1 a "mediocre, but not completely incompetent" graduate-student simulation two years ago, and, four days ago, saying "we have to slow down... There's no reason at all" for this pace. His own claims are stronger: lab staff allegedly say the last six months outran expectations, "Pacing the Frontier" is driven mainly by fear, and RSI arrives by next summer. None of this is verifiable from these posts, so treat it as one informed observer's argument. The everyday counterpoint comes from @bashu_thanks, who says using frontier AI as a dev feels like "playing Watson to Sherlock Holmes," mostly standing back and occasionally stopping him from getting shot.
Jev everywhere: decision models as cheap judgment
A large cluster of posts shows "Jev"-style decision models moving from novelty to default plumbing. @vllm_project announced DiffusionGemma-Jev runs on vLLM: ask yes/no, multiple-choice, or scored questions and get confidence, by seeding a canvas with the response template and reading a probability distribution from every slot in a single denoising step, with upstream work credited to @mmastrac. The quoted @googlegemma post adds one-command Cloud Run deploys at roughly 35-60 ms single-step latency, batch throughput of ~100-123 requests/sec at 32, and about $3/hr dropping to $0 idle.
Practitioners are wiring it in. @sydneyrunkle uses SemIf, "like jev, but open source," to label incoming issues on open-source repos, one noul per label with a p>0.8 application threshold, reporting it's faster than the previous LLM classifier while they monitor calibration. That follows @Hacubu's announcement that SemIf is served free through the LangSmith Gateway for a week, compatible with the TypeSafe SDK. @iannuttall updated his internal-linking tool to handle 2,000 URLs with week-long emailed reports on Cloudflare Durable Objects; the original version used Jev for link classification, and he suggests asking "Opus 5.5" to extend it further. @typesafeai quote-posts @anishfn's text box that turns into whatever UI you type, arguing Jev might crack dynamic UIs, "a famous graveyard" for PMs and products. @mikeldking awards "1 point for decision models" in his ongoing thread on Jev and System One semantics. @FareaNFts lists 20 Jev skills, from jev-ultrafast (browser agent) and fast-jev-compaction to canny (checking whether an agent really finished) and killmyidea, building on an earlier claim about cutting agent bills 400x. The hype cycle is already running ahead of the tooling: @EGafni's entire response to @JulianLaneve's "Jev's going to change data engineering" is "Intelligence Everywhere!!!!"
Agentic tooling: OpenCode 2.0, Moshi, and a testing spat
OpenCode v2.0.0 (@OpenCodeLog) is a sprawling release. Code Mode is a sandboxed JavaScript interpreter letting models compose and execute tools via OpenAPI schemas without direct filesystem or network access; the V2 session core adds durable prompt inboxes that decouple admission from execution; the desktop app gains SSH remoting, a Chromium pane with DevTools diagnostics, and a SQLite-backed state store; MCP gains elicitation forms and runtime server management; ACP v1 support lands across runtime and CLI. Elsewhere, @RayFernando1337 calls Moshi "GOATed for managing agents via Terminal UI," quoting @odd_joel polishing it for "the iphone duo," and @Voxyz_ai notes a Claude Code subscription can be used from Codex, with Astra coordinating up to 10 Claude Code instances (the post is truncated).
The sharpest disagreement of the day is about testing. @nateberkopec's claim that "unit tests are dead in the water," because model-written ones are terrible, drew a detailed rebuttal from @sasajuric: good testing practices shouldn't change in the agentic era. His approach is to test through the outermost API, complement with internal tests where needed, and remember that the unit is behavior, not code, citing Vladimir Khorikov and Ian Cooper, with BEAM, Elixir, and Phoenix keeping such tests reasonably fast. Smaller but useful: @joelhooks says his uncomplect skill is "how i 'read the code'" now, with @bios_hazard showing the one-liner invocation; @RhysSullivan calls the effect+alchemy+cloudflare combo a "super powers stack" of tech that became 100x easier to adopt with AI; and @kitlangton deployed something called OPENTUNNEL for anyone to poke at.
Papers, books, rumors, and stock counts
@omarsar0 highlights WFM, a Wiki Foundation Model that stores agent memory as a linked markdown wiki, turns it into a graph, and retrieves via message passing conditioned on the query, with a GPU-to-GPU training protocol the authors report as 10.5x faster, validated on five agent-memory and multi-hop reasoning benchmarks. @GergelyOrosz points to a free WIP O'Reilly book, supported by @AntithesisHQ, on getting AI to deliver business value for CTOs and engineering leaders. @lennysan recommends the new evals skill from @HamelHusain and @sh_reya; his accompanying post cites Ramp lifting receipt collection from 35% to 83%, Shopify's 2.2x faster and 68% cheaper workflow builder, and Cursor cutting routing costs 41%, though these are his citations rather than audited results. In the rumor bin: @jun_song amplifies @yume_arasaki calling EXL3 "the biggest paradigm shift in local LLMs"; @doqholliday reacts to X's announcement of X Numbers, optional contact details for calls and messages without following back, as Elon "quietly inventing his own phone number system"; and @MikeBradleyAI relays @loktar00's report that fewer than 100 Sparks units remain across Micro Center, with 9 stores still holding stock.
Practical Takeaway
If you have a classifier-shaped task in your stack, this week is a cheap time to test the decision-model route. With @Hacubu's free SemIf week via the LangSmith Gateway and @vllm_project's native DiffusionGemma-Jev support, try replacing one low-stakes LLM classifier and copy @sydneyrunkle's discipline: a confidence threshold (p>0.8), then monitor calibration drift before letting it touch anything production-critical.

How to cut your agent bill 400x with Jev (full setup + 20 real use cases)
While I don't want to say too much, hold out hope for a Qwen4-35B-A3B. It may not have been announced, but I know one is being tested.
Evals have been coming up more and more in my conversations with podcast guests and PM friends. Nearly half of the 25 awesome PM job openings I shared last week ask for experience writing evals. And leading companies keep sharing what investing in evals bought them: โ @tryramp took its automatic receipt collection from 35% to 83% accuracy. โ @Shopify shipped an AI workflow builder that's 2.2x faster and 68% cheaper than the frontier-model setup it replaced. โ @harvey__ai rebuilt its AI contract reviewer, nearly doubling its internal quality score. โ @cursor_ai tuned its Auto Balance routing, with much higher user satisfaction at 41% lower cost. So I asked the ๐s of evals, @HamelHusain and @sh_reya, to write an advanced sequel to their very popular "Building eval systems that improve your AI product." Drawing on their work with 50+ AI companies, they share the key step most teams skip, what you should (and shouldn't) automate, and a free plugin that lets a coding agent do most of the heavy lifting.

X Numbers are here. Share yours with anyone you want to contact you, even if you don't follow them. It's an optional way for people to message or call you, without you needing to accept requests or follow them back. https://t.co/HkObZSQMhm

Jev's going to change data engineering
๐ Free Open-Source Jev ๐ค LangSmith Gateway Decision models are becoming a first-class part of the LangSmith Gateway! We're serving SemIf, an open-source decision model, free for the next week. Compatible with the TypeSafe SDK - just change a string to try it! Docs in ๐งต https://t.co/hHHbTAfJiw
haven't had this much fun building in a while. polishing moshi for the iphone duo and every small detail feels worth it. https://t.co/jHyUvfMCjE
nobody talking about the effect+alchemy+cloudflare combo to literally build f'n anything why not?
Okay, we need good semantics around Jev. In one word, Jev / System One models are
O P E N T U N N E L ? ! https://t.co/spNv0L1s0j
i built a text box that turns into whatever(some ui) you type. powered by jev https://t.co/HH0P51033y
i don't think nearly anyone, myself included, has truly internalized there'll soon be a machine better than us in every single intellectual & physical capacity deep down we all share a feeling that our 'entrepreneurship' or 'taste' or... is special & safe. it isn't. it's over
Deploying DiffusionGemma-Jev (djev) just got a lot easier. You can now spin up a Jev API-compatible endpoint on Google Cloud Run using a single command. Performance is solid: ~35-60 ms for single step latency and batch@32 is ~100-123 requests/sec. It's a straightforward way to experiment without needing your own GPU. Runs at roughly $3/hr and drops to $0 when idle. Get the code and instructions here: https://t.co/E3agzrW2hZ
I agree with @thorstenball, I think unit tests are dead in the water. The ones the models write are terrible, at best just doubling total LOC. Inverting the testing approach - heavy e2e/black box/golden master, reaching for lower levels only if necessary, works better for me
I built a free internal linking tool using @typesafeai Jev for classifying and selecting the links. BYOK or pay $1 to use mine. It works for up to 500 pages and gives you a CSV or JSON to pass to an LLM to implement. https://t.co/i01qMCEXa6 https://t.co/7uhzyaiGQj
