Opus 5 + Claude Voice Released (It’s basically Jarvis) | Riley Brown

The Gist

Anthropic has released Opus 5 at half the price of Fable 5, alongside new voice modes for iOS and desktop apps that mirror features from OpenAI, highlighting an accelerating race for AI agent dominance.

Quick Overview

Anthropic launched Opus 5 as an everyday model for enterprises and developers at half the cost of Fable 5, while rolling out real-time voice modes across iOS and Codex. Meanwhile, Anthropic and OpenAI are rapidly copying each other's features, including browser updates, multi-tab interfaces, and screen recording integrations, as they converge on universal agent super-apps.

Key Points: Anthropic introduced Opus 5, a model priced at $5 per million input tokens and $25 per output tokens, coming close to the frontier intelligence of Fable 5 at half the cost. Dan Shipper reported that Opus 5 required deleting existing complex workflows because it natively argued with instructions and behaved differently than prior models. Anthropic added a real-time voice mode to its iOS app that connects directly with tools like Google Calendar, Slack, and Notion. OpenAI launched voice chat inside Codex and added an iOS simulator feature that lets users build and run Swift apps directly in a side panel. Claude and Codex have independently converged on nearly identical three-tab interfaces for chat, work, and code tasks. Codex introduced a record and replay feature that turns user screen recordings into executable automation skills. Chinese developers are rapidly launching equivalent super-apps and models, including Z Code from the GLM team and Kimi Code from Kimi K3.

Context: The field of generative artificial intelligence is moving past simple chatbots toward autonomous agents capable of complex knowledge work across multiple applications. Anthropic and OpenAI are competing aggressively to build all-in-one super-apps that integrate voice, browser control, and system execution.

Detailed Analysis

Anthropic released Opus 5 as a high-performance model targeted at knowledge workers and developers for half the price of Fable 5. Early testers like Dan Shipper found that the model required stripping out previous custom engineering workflows because it operated effectively out of the box. Alongside the model release, Anthropic and OpenAI rolled out real-time voice modes and cross-platform desktop integration features. Both companies are racing to consolidate tools into unified super-apps, copying each other's browser tabs, mobile voice capabilities, and screen recording tools.
