Vercel's ephemeral compute primitive for untrusted, AI-generated code is generally available. Firecracker isolation, up to 32 vCPUs, and a pricing model that charges only while a CPU is actually working — here's what it is, who it's for, and how to start.

Your agent forgets everything the moment the request ends. Mem0 is the memory layer you add in two calls — it extracts what matters from a conversation, stores it, and hands the right facts back on the next turn, per user.

One model doing everything is hard to steer. CrewAI lets you split a job across a crew of role-specialized agents — a researcher, a writer, a reviewer — and orchestrate how they hand work to each other, in plain Python.

Pydantic AI v2.9 shipped a /usage command for cumulative token tracking and — the real upgrade — exposed the run's usage_limits to your tools. Here's how to set a hard budget, read what's left from inside a tool, and stop a runaway agent before the bill lands.

A code-forward walkthrough for getting every memory out as structured JSON you control — add, get_all, re-import — so no vendor's shutdown can delete your users' context.

OpenAI audited SWE-Bench Pro, found ~30% of its 731 tasks mismark correct code as wrong, and pulled its own recommendation. If you pick a coding model on a two-point benchmark gap, you're routing on noise.

In three releases across five days, the OpenAI Agents SDK made GPT-5.6 the default and quietly added 'hosted multi-agent beta support' — a path to run agent fan-out on OpenAI's infrastructure instead of your own. Here's what's actually in 0.18, and the decision it forces.

The 2026-07-28 spec deletes the handshake and the session. Here's the concrete diff — drop `initialize`, read capabilities from `_meta`, and replace held-connection elicitation with Multi Round-Trip Requests — with old-vs-new code for each step.

Mem0's token-efficient rewrite stops doing UPDATE and DELETE when it stores a memory, and pushes the hard part — reconciling contradictions — to read time. That's not a free win. It's a bet about where you can afford to spend.

The 2026-07-28 spec kills server-initiated sampling but keeps elicitation — and adds a URL mode built for exactly the flows you couldn't do before: OAuth, credential entry, and payment setup that must never touch the model context.

The release candidate everyone read for the deprecations buried the bigger change: MCP is no longer a session. It's a stateless request/response protocol you can put behind a plain load balancer — and that quietly rewrites how you deploy every server you own.

Both run vector, full-text, and hybrid search off object storage at billion scale. The real fork is whether your data stays an open file you own, or lives behind one vendor's API.

Intercept the tool call, pause for a human approve/deny/edit, then resume from the exact checkpoint — and put the gate where risk lives, not on every call.

Your tool schemas are the fattest, most stable block in every agent request — and the single highest-leverage thing to cache. The trick is not breaking the prefix.

On Agents' Last Exam — the benchmark for long-running professional workflows, where agent products actually die — GPT-5.6's cheapest tiers now clear a bar that Claude Fable 5 couldn't. The premium you pay for a frontier model just stopped being obvious.

China switches off its two biggest AI companions tomorrow, Google turned managed agents into background jobs, and open-weight coding got cheaper — the three shifts that change what you ship this week, and what to do about each before Monday.

From July 1, every Cursor Teams seat carries two separate usage pools and comes in Standard or Premium. It's the clearest sign yet that agent pricing is settling into 'predictable seat + separated model spend' — and a map for picking the seat by your bottleneck, not the brand.

On July 15 China switches off its companion agents. But it's the third jurisdiction in nine months to write 'AI companion' into law as a category — and the test they all use decides whether your product is regulated.

Google now spawns a locked-down, millisecond sandbox inside your existing Cloud Run instance — no env vars, zero egress, no premium. For anyone already on GCP, the build-vs-buy math for running agent code just changed.

Sonnet 5 is a drop-in replacement for 4.6, but it turns adaptive thinking on by default and max_tokens now caps thinking plus response. Two forces quietly push your final answer toward truncation. Here's the 20-minute migration that doesn't cut your agents off mid-sentence.

Claude Managed Agents let you swap the model, system prompt, tools, MCP servers, or skills for a single session with agent_with_overrides — no new agent version, no config drift. Here's the exact call, the tri-state rules, and the two 400s that will bite you.

The Rust rewrite made Chroma fast, but the architecture that matters is where the index lives. Chroma serves search from S3-class storage, which sets the exact cost and latency shape you're signing up for.

Both raised this month to build the worlds your agent lives in, and the pitches sound identical. They aren't: one makes your agent better, the other tells you where it breaks. Which you need depends on which problem you actually have.
