Anthropic just dropped a 13-page PDF on Agent Memory - 5 layers that cut token cost 90% and make your agent actually learn:
here's the 5-layer memory architecture:
layer 1 โ working memory - the context window. everything the agent sees right now. when it fills up, old context dies. most agents stop here and wonder why they're broken
layer 2 โ episodic memory - what happened. full interaction logs with timestamps. the agent recalls that the deploy failed Tuesday at 3am because the migration script had a typo
layer 3 โ semantic memory - what is true. facts, entities, relationships stored as a knowledge graph. "user prefers TypeScript" lives here. doesn't expire when the session ends
layer 4 โ procedural memory - how to do things. the agent tried 3 approaches, one worked. that method becomes a reusable skill. next time it skips straight to what worked
layer 5 โ forgetting - what to delete. an agent that never forgets accumulates contradictions. old preferences override new ones. the user moved cities but the agent still recommends restaurants in the old one
the result: Mem0 stores 1,800 tokens per query instead of 26,000. Snowflake added one ontology layer - 20% better accuracy, 39% fewer tool calls. memory pays for itself on day one
this 13-page PDF is what separates a chatbot from an agent that actually learns

A Harvard student just found a genius way to slash LLM API token usage by 95% - dropped a whitepaper on GitHub.
The twist: the token count drops massively the moment you stop sending text and turn your codebase into a PNG image.
here's the whole method, step by step:
step 1 โ Standard prompting gets expensive - dumping raw code into the context window burns your API budget fast.
step 2 โ pxpipe intercepts the data - a local script renders your text and code files into highly compressed, dense images.
step 3 โ The LLM reads it visually - multimodal models (like Claude 3 or Gemini) process the image tokens instead of text tokens.
step 4 โ Massive cost reduction - visual processing is priced significantly lower, saving up to 95% on tokens without losing reasoning quality.
Bookmark and read the full method in the document below.
Anthropic just dropped a 1-hour workshop on how to actually build with AI in 2026:
00:26 - Why they stopped prompting
16:57 - The system that builds, tests, and fixes itself
25:27 - One engineer replacing a 5-person team
36:25 - Building your first loop from scratch
This 1-hour watch could replace 10 AI engineering courses on the internet.
Watch it today, then read the step-by-step guide on building loops below.
๐จJUST IN: 7 hours ago ANDREW NG dropped one of the MOST VALUABLE FREE AI COURSES OF 2026.
Most AI agents are brilliant but forget everything.
This course fixes that. I went through it.
Here's why this is THE MOST IMPORTANT SKILL OF 2026.๐

The guy who created Claude Code ( @bcherny ) just leaked how his team uses Claude.
One CLAUDE.md, you drop it at the root of your project.
Inside: past errors, conventions, rules -Claude reads it at every session.

๐๐ ๐ข๐ฏ๐๐ฒ๐ฟ๐๐ฎ๐ฏ๐ถ๐น๐ถ๐๐ is a must have in your tool belt as an AI Engineer. ๐ง๐ฟ๐ฎ๐ฐ๐ถ๐ป๐ด sits at the core of it, why is it important?
Tracing and instrumentation of software have been around for decades now. With AI systems resembling regular software even more, we are now moving the practice here as well (with a few key differences).
Letโs look into the process of tracing from a perspective of a naive RAG system.
๐๐ฆ๐ธ ๐ฅ๐ฆ๐ง๐ช๐ฏ๐ช๐ต๐ช๐ฐ๐ฏ๐ด:
๐ผ) An Orchestrator in the GenAI system application is the central piece of software that orchestrates the end-to-end process. Think of apps using LangChain, LlamaIndex or Haystack.
๐ฝ) Trace is the end-to-end application flow from the entry point till the answer is produced, it is composed of smaller pieces called spans.
๐พ) Span is a smaller piece of the application flow that represents an atomic action like a function call or a database query. They can be sequential, or run in parallel.
โน๏ธ As part of span we capture general metadata like start and end time, inputs and outputs of the span. On top of this metadata we track information specific to the GenAI system elements.
What might a trace look like for a naive RAG system?
๐ญ. A query that has been submitted to the chat application.
๐ฎ. The query is embedded into a vector.
โ Additional metadata like input token count is persisted with the span so that we can estimate the cost of the procedure.
๐ฏ. ANN lookup performed against the Vector DB to retrieve the most relevant context.
โ Additional metadata about the query is persisted as part of the span together with the retrieved pieces of context and their relevance.
๐ฐ. A prompt is constructed from the system prompt and retrieved context.
๐ฑ. The prompt is passed to the LLM to construct the answer.
โ Additional metadata about input and output token count is captured together with the span so that we can estimate the cost of the procedure.

- These applications are usually complex chains, errors can happen in different steps of your application. E.g. Embedding of query is taking longer than expected or you have reached API limits of LLM provider.
- Cost for calling LLM APIs will be variable depending on the length of inputs and produced outputs. You would usually trace this information and analyze it to help forecast expenses.
- GenAI systems are non-deterministic and will deteriorate over time. They need to be evaluated on span level rather than input/output of the entire system so that you can tune each piece separately.
