+
+** what are ai agents
+- what is it at its core
+- what can it do
+- why do we need them
+
+#+caption: what is an ai agent
+#+attr_html: :width 600px
+[[../../_share/media/img/compsci/ai/herk/build_8hr/ch01_e01.png]]
+
+*** what it does
+- take input
+- process input
+- get output
+
+*** how to use it
+- send the output to a tool
+  - gmail
+  - latex
+  - anything
+
+- when we add an LLM to a tool we get
+  - ai workflow
+  - ai agent
+
+*** workflow vs agent
+**** ai workflow
+#+caption: ai workflow
+#+attr_html: :width 600px
+[[../../_share/media/img/compsci/ai/herk/build_8hr/ch01_e02a.png]]
+
+***** pros
+- reliability
+- cost efficiency
+- easier debugging and maintenance
+- scalability
+
+***** what we are doing
+- input
+- tools to process input
+- call the LLM
+- tool chain
+  - process output before final output
+- final output
+
+***** practical example
+- hubspot tool
+  - passes in lead
+
+- perplexity tool
+  - does research
+
+- LLM
+  - takes research
+
+- send email
+
+**** ai agent
+#+caption: ai agent
+#+attr_html: :width 600px
+[[../../_share/media/img/compsci/ai/herk/build_8hr/ch01_e02b.png]]
+
+***** how it works
+- takes input
+- has a set of tools at it's disposal
+- uses internal logic to decide what to do
+
+***** disadvantages
+- not linear
+- expensive
+
+***** when to use it
+- if the task is unpredicatable
+
+**** anatomy of an ai agent
+#+caption: anatomy of an ai agent

+
+***** outside features
+- input
+- LLM
+- output
+
+***** in the agent
+- brain
+  - LLM
+    - anthropic
+    - gemini
+  - memory
+    - long term
+    - short term
+    - it won't forget what we need it to remember
+
+- instructions
+  - system prompt
+    - differnt than input in that it stays the same
+    - input changes regularly, ie every interaction you have with chatgpt
+  - what is your role
+  - what do you do
+  - this is what you got to work with
