Anthropic Releases Opus 4.6 with Capability to Deploy Teams of Agents

Anthropic just released Opus 4.6, upgrading its smartest model beyond coding into wider knowledge work and turning Claude into “digital coworkers” built for complex reasoning and collaboration.

Details:

• It adds “agent teams” in research preview, letting multiple agents split big tasks, coordinate, and work in parallel. It can also run longer jobs and fix some of its own mistakes

• Performance jumps with a 1M token context window and stronger benchmark results. It beats OpenAI’s GPT-5.2 by 144 Elo on economic tasks and leads on Humanity’s Last Exam and coding tests

• Usability improves with native PowerPoint side panel for building decks inside the app. Reliability also rises for finance analysis, research, and deep coding, making it stronger for product managers and analysts

With these updates, Anthropic claims Opus 4.6 operates reliably in massive codebases and plans more carefully than any predecessor.

GPT 5.3 Codex Is The First OpenAI Model To Help Create Itself

This morning, Anthropic and OpenAI launched rival agentic coding models minutes apart. Anthropic moved Claude Opus 4.6 up by 15 minutes, and OpenAI replied with GPT-5.3-Codex, shifting from code reviews to a near full-stack developer agent.

Details:

• OpenAI says this is its first model that helped build itself, with early versions used to debug training, handle deployment, and speed up development. Staff said the results “blew them away”

• It set record scores, winning Terminal-Bench 2.0 by double digits, and scoring 57% on SWE-Bench Pro and 64% on OSWorld. That suggests it can build complex apps and games from scratch over days

• It’s also more efficient: over 25% quicker per token and needing less than half the tokens vs GPT-5.2. It’s delivered through a macOS app interface built to manage multiple agents at once

With engineers at both firms saying most coding is done by AI, this dual release marks the shift from AI-assisted coding to fully autonomous software engineering workflows.

AI Tutorial

How to Listen to Any PDF and Ask Questions in Real Time

Most summaries miss what you actually want. Sometimes you just need the main idea, the key takeaway, or a simple explanation. This method does that: upload your book or PDF to ElevenReader, and the AI answers using the real text.

1. Download right app

   Download ElevenReader app and sign in. The complimentary plan is generous.

2. Add book or document

   Tap “Upload your content”, then add your content using one option:

   • Paste a link

   • Type in text

   • Upload a file

3. Launch it from library

   Your uploaded content will appear in your library. Tap it to open.

4. Listen with AI narrator

   Press Play to hear it read aloud. You can also switch to a different voice if you want.

5. Start voice chat

   Tap the voice chat button in the bottom right corner. Ask smart questions while the content is available. Try questions like:

   • “Explain the main idea in 5 bullets.”

   • “What are the key takeaways I should remember?”

   • “Summarize each section in 2 lines.”

6. Use it like study buddy

   You can ask about characters, themes, plot points, worldbuilding, or receive a full summary. The narrator remembers context and answers based on the actual text.

Note: When studying, ask “What should I remember for an exam?” instead of a generic summary.

Create Your Own Photo Like This Using the Prompt Below:

A slim young man riding a powerful black horse, captured from a low front three-quarter angle. He sits upright, holding the reins naturally, gazing slightly to the side with a calm, fearless expression, face fully visible and sharp. The horse is muscular with a thick flowing mane and tail, captured mid-gallop with all four legs visible in motion. Subject and horse are in sharp focus while the background is heavily motion-blurred with horizontal streaking lines suggesting high speed. He wears an oversized white linen shirt with open buttons and rolled sleeves, light blue baggy jeans, white Nike Air Force 1 sneakers, a silver wristwatch on his left wrist, and narrow rectangular sunglasses. Face must remain 100% identical to the reference—no facial changes, smoothing, beautification, or face swap. Monochrome black-and-white with deep contrast, dramatic cinematic lighting from the side, subtle film grain texture, shallow depth of field keeping rider and horse razor-sharp. Leica M11-style vintage editorial aesthetic with motion blur streaks in background, panning photography effect. Ultra-realistic, cinematic composition with dynamic sense of movement and speed.
