Article by **Paul Sawers** published on **The New Stack** on **June 16, 2026**, about the **suspension by Anthropic** — *"on the very day it was scheduled to go live"* — of the billing split meant to separate **Agent SDK** usage from Claude subscription limits. **Anthropic's cited message**: *"We're pausing the changes to Claude Agent SDK usage described below. For now, nothing has changed."* **The article's contribution is not the announcement but the surrounding context**, in three circles. **Circle 1 — Anthropic's week**: on June 9, the release of **Fable 5 and Mythos 5**, the first generally available Mythos-class models with hardened cybersecurity safeguards; a few days later, a **US government export control directive** forces Anthropic to **withdraw both models for all its customers worldwide**. The pricing suspension is read as *"a little good news"* in this context. **Circle 2 — collateral damage from the timing**: companies that had already passed the change on to their own customers find themselves caught out; **Conductor**, a multi-agent coding tool built on the Agent SDK, has to issue a denial (*"Anthropic has delayed the subscription updates to Claude plans"*). **Circle 3 — the underlying tension, which extends beyond Anthropic**: a quote from **Boris Cherny** (head of Claude Code) in April, during an earlier restriction, stating that subscriptions *"weren't built for the usage patterns of these third-party tools"* — an admission that **flat-rate plans and open-ended agentic usage don't mix**; **GitHub** settled the matter the same way, removing in June **Copilot**'s flat-rate *premium requests* model in favor of **token-based billing**, despite protests. Added to this, **the same week**, a **proposed class action** was filed in a California federal court, alleging that **Max** tiers fall well short of the usage multipliers advertised for intensive coding sessions. Anthropic does not say when a revised approach will arrive, only that it *"works to update the plan to better support how users build with Claude subscriptions."* **The author's final take**: between government pressure on Fable and Mythos, a planned **IPO**, and **rumored price cuts at OpenAI**, Anthropic is trying to **keep its developer base on its side** — and the suspension is, for now, a means to that end.

**Zed** blog post signed by **Franciska Dethlefsen** (head of growth and marketing), published on **May 14, 2026** — the day after Anthropic's announcement — to answer Zed users' questions. **Subject**: starting **June 15**, Anthropic **splits Claude subscription billing into two pools** — one for its **first-party tools** (chat, the official Claude Code CLI), the other for **third-party agent and SDK usage** (anything going through **ACP**, `claude -p`, or a third-party tool). Usage via ACP **then stops drawing from the Pro or Max limits** and switches to a monthly **"Agent SDK" credit**: **$20 for Pro, $100 for Max 5x, $200 for Max 20x**. Once the credit is exhausted, usage continues **at standard API pricing** if overage is enabled — otherwise requests stop until the next cycle. **The figure driving the article**: subscriptions had until then subsidized agentic usage by a factor of **≈15 to 30×** relative to API pricing, and the new credits are billed **at full API rates** — hence *« for anyone using agents heavily, this is a major cost increase »*. **Three options are proposed**, in an order that reveals Zed's position: (1) keep the subscription by running the **official `claude` CLI in a terminal inside Zed** rather than via ACP — *« when the official claude CLI runs in the terminal, it uses your subscription's limits, not the new credit »*; (2) use Zed's built-in agent with the provider of one's choice (Zed-hosted models, API keys, Copilot, local Ollama, DeepSeek); (3) plug in **any ACP agent** — OpenCode, Codex, Factory, Cursor —, several of which still offer rate-limited subscriptions that subsidize heavy usage. **The underlying thesis**, and the real reason for the post: *« ACP is an open protocol… so that your editor is never locked into one provider's pricing decisions »*, with the explicit anticipation that *« this kind of change won't be the last »*. **The post carries an addendum dated June 16, 2026** announcing that **the change is suspended**: ACP, `claude -p`, the Agent SDK, and third-party applications continue to work with subscriptions **as before**, no separate credit to claim, limits unchanged, Anthropic revising its plan with advance notice announced. **The artifact is thus self-contradicting**: its most important content — the reversal — postdates its own publication date by a month.
