Version 2.1.239 fixes streaming on Bedrock behind proxies that remove the response Content-Type header. Claude Code silently fell back to re-running every turn without streaming, and each turn was billed twice. The same release makes cost estimates show the 1.1× premium that data-residency workspaces pay.

OpenAI cut Sol's API price on August 21: input from $5 to $4, output from $30 to $20, cached input from $0.50 to $0.40. On a standard task the model goes from more expensive than Claude Opus 5 to cheaper than it. The cut is promotional and runs at least through November 21.

Nvidia published a run in which AVO, its agent architecture, scores 100.00 RHAE on ARC-AGI-3 and clears all 183 levels across 25 environments. The same model evaluated on its own scores about 30%. In the same post Nvidia writes that the comparison is not a controlled ablation, and that sentence did not survive into the coverage.

Both drive a web browser, both stop before the step that cannot be undone, and their lists of stopping points are nearly the same. The difference is what each assumes about the session it runs in: one is built on the accounts you are already signed into, the other tells you to give it a browser with no credentials in it. That single assumption decides which of the two belongs anywhere near your work.

Six models, one task, one number: what a thousand calls cost when each sends 4,000 tokens in and gets 800 back. The cheapest row is $1.76 and the most expensive is $16.00, a nine-fold spread rather than the hundred-fold spread the category implies. Two things move the ranking more than the headline price does, and one of them has a date on it.

Two disclosures first: this is a reading of the vendor's own evaluations rather than our test, and it is written by a model that vendor built. With both stated, the published numbers still contain three things worth noticing before you pick this model.

Both start at $20 a month, both speak MCP, both run skills and hooks, both reach CI. The difference is not the feature list. It is whether the agent lives inside an editor you adopt or inside the terminal you already have.

Sol's price cut on August 21 put it below Opus 5 on both short-context columns — $4 against $5 on input, $20 against $25 on output. Its long-context column went the other way and still costs more. Opus 5's price sits between Sol's two columns, so the cheaper model depends on which column your request lands in, and OpenAI does not say where the boundary is.

Four levers, all published, none of them clever: cache the fixed part of your prompt, batch what can wait, drop a tier where the task allows it, and stop paying multipliers you did not ask for. Worked all the way through on one real workload.

August 19 brought two changes to how Claude operates someone else's screen. The computer use tool moved to general availability as computer_toolset_20260801, with no beta header, actions grouped into a single turn, and zoom enabled from the start. Alongside it came browser_toolset_20260801, a separate set of 31 tools that works inside a browser you run yourself rather than across the whole desktop. The important difference is that this set reads the page accessibility tree and returns element references, so a click targets a reference such as ref_2 instead of a point in pixels — and that survives a layout shift.

The August 20 release fixes what got in the way during long stretches of work rather than adding features. Tool results returned by subagents are now freed as soon as they leave the recent-view window, so memory in long interactive sessions stops growing without a ceiling. The release also fixes custom output styles sliding back to the default tone mid-session, along with a run of stalls in Remote Control. A new keybindingFlavor setting restores Bash behavior, where Ctrl+W deletes back to the previous space, and claude mcp list no longer starts disabled servers just to check their status.

Since August 18, Workbench in the Claude console is called Playground and has been rebuilt from the ground up. The new tool supports every Messages API parameter and ships with templates that show how code execution and web search work. For every run it displays the complete request exactly as the SDK sends it, along with the raw API response, which makes it a way to learn the API rather than only a place to try prompts. The old Workbench shut down on August 17, saved prompts and evaluations do not carry over, and the experimental prompt tools APIs for generating and improving prompts were withdrawn with it.

On August 19, Anthropic moved a large part of the Claude platform from beta to general availability. The Files API no longer requires a beta header and gains file expiry through expires_in_seconds, pagination, and filtering by identifier, alongside a terabyte of storage per organization and a limit of 500 requests per minute. Agent Skills and the accompanying Skills API also became generally available, so skills now load through the Messages API without a single beta header. Managed Agents gain allow and block lists of domains for search and content fetching, and the session viewer in the console was redesigned with a timeline minimap and an Inspector panel. Anyone building an agent over client content gets three critical parts of the API that stop being a moving target.

Two open sessions can talk: Claude finds the others with ListAgents and sends a message through SendMessage, either because you asked or on its own when a change in one session affects the work in another. Only text Claude writes crosses over — never conversation history, never files. Since version 2.1.232 you can also address a session directly by typing @ followed by its name. The feature runs on macOS and Linux and needs version 2.1.224 or later, and /list-agents shows what is available. It pays off most when you keep the frontend and backend of the same project in separate sessions.

Since August 14, auto mode is the default permission mode for new sessions on the Pro, Max, and Team plans. Instead of interrupting at every action, a classifier in the background lets safe actions through and stops risky ones. If you set a default mode yourself, it stays in force until you accept a one-time offer to switch, and a mode an organization mandates does not change automatically. One detail matters for your quota: the classifier calls auto mode makes no longer count against usage limits.

Three releases in three days change several things about daily work. Version 2.1.237 introduces a built-in Concise output style, in which Claude leads with the result and skips the preamble and the recap, and fixes prompt caching for sessions that go through a proxy gateway or a custom base URL. Version 2.1.236 adds the ANTHROPIC_DEFAULT_MODEL environment variable, which sets the model new sessions start on, and a notify_when_idle option that asks another session to report when it frees up. Version 2.1.235 introduces optional spell checking through aspell, hunspell, or ispell, and reduces memory and processor use for sessions running in the cloud.

The new flagship in the Opus line lets you set how much effort it spends on a task, across three levels — low, medium, and high — which gives you direct control over the trade-off between cost and quality. Pricing stayed where it was with 4.8, at five dollars per million input tokens and twenty-five per million output tokens, while scores on a large share of tasks sit close to Fable. Opus 5 became the default on the Max plan and the strongest model available on Pro, and it is called in the API as claude-opus-5.

Anthropic published an official explanation of the mechanism that writes a watermark into text Claude generates. With the new European labeling rules, the subject stops being a technical curiosity and enters compliance territory, because it offers a way to establish the origin of content even when whoever publishes it does not say so.
