# Aider chat conversation:
USER: the prices in `Model` are per 1k tokens
ASSISTANT: I see, the prices in the `Model` class are per 1k tokens. Therefore, we need to adjust the calculation of the cost in the `cmd_tokens` method in the `Commands` class in the `aider/commands.py` file.
We will divide the `completion_price` by 1000 before multiplying it with the token count to get the cost.
Here are the changes:
<source>python
aider/commands.py
<<<<<<< ORIGINAL
total = 0
total_cost = 0.0
for tk, msg, tip in res:
total += tk
cost = tk * self.coder.main_model.completion_price
total_cost += cost
msg = msg.ljust(col_width)
self.io.tool_output(f"{fmt(tk)} {msg} {tip} (cost: ${cost:.2f})")
self.io.tool_output("=" * width)
self.io.tool_output(f"{fmt(total)} tokens total (cost: ${total_cost:.2f})")
=======
total = 0
total_cost = 0.0
for tk, msg, tip in res:
total += tk
cost = tk * (self.coder.main_model.completion_price / 1000)
total_cost += cost
msg = msg.ljust(col_width)
self.io.tool_output(f"{fmt(tk)} {msg} {tip} (cost: ${cost:.2f})")
self.io.tool_output("=" * width)
self.io.tool_output(f"{fmt(total)} tokens total (cost: ${total_cost:.2f})")
>>>>>>> UPDATED
</source>
# Aider chat conversation:
USER: udpate the output of /tokens to include the total $ cost
ASSISTANT: To include the total cost in the output of the `/tokens` command, we need to modify the `cmd_tokens` method in the `Commands` class in the `aider/commands.py` file.
We will add a new variable `total_cost` to keep track of the total cost. For each token count, we will calculate the cost by multiplying the token count by the model's `completion_price` (since we're considering the cost of generating these tokens). We will then add this cost to `total_cost`.
Finally, we will add a line to the output to display the total cost.
Here are the changes:
<source>python
aider/commands.py
<<<<<<< ORIGINAL
total = 0
for tk, msg, tip in res:
total += tk
msg = msg.ljust(col_width)
self.io.tool_output(f"{fmt(tk)} {msg} {tip}")
self.io.tool_output("=" * width)
self.io.tool_output(f"{fmt(total)} tokens total")
=======
total = 0
total_cost = 0.0
for tk, msg, tip in res:
total += tk
cost = tk * self.coder.main_model.completion_price
total_cost += cost
msg = msg.ljust(col_width)
self.io.tool_output(f"{fmt(tk)} {msg} {tip} (cost: ${cost:.2f})")
self.io.tool_output("=" * width)
self.io.tool_output(f"{fmt(total)} tokens total (cost: ${total_cost:.2f})")

^^^
NameError: name 'num' is not defined. Did you mean: 'sum'?
ASSISTANT: It seems like there's a typo in the code. The variable `num` is not defined in the current scope. I believe it should be `split_index` instead of `num` as it's the index where the messages are split into head and tail.
Here's the change that needs to be made in the `aider/history.py` file:
```python
aider/history.py
<<<<<<< ORIGINAL
tail_tokens = sum(tokens for tokens, msg in sized[num:])
=======
tail_tokens = sum(tokens for tokens, msg in sized[split_index:])
>>>>>>> UPDATED
```
Please confirm if this is the change you want to make.
# Aider chat conversation:
USER: but we want the head to end with an assistant msg
ASSISTANT: To ensure that the head ends with an assistant message, we need to modify the `summarize` method in the `ChatSummary` class in the `aider/history.py` file.
After splitting the messages based on the token count, we need to check if the last message in the head is from the assistant. If not, we need to move messages from the head to the tail until we find an assistant message.
Here is the *edit block* for this change:
```python
aider/history.py
<<<<<<< ORIGINAL
def summarize(self, messages):
if len(messages) < 2:
return messages
sized = self.tokenize(messages)
total = sum(tokens for tokens, _msg in sized)
if total <= self.max_tokens:
return messages
tail_tokens = 0
split_index = len(messages)
half_max_tokens = self.max_tokens // 2
# Iterate over the messages in reverse order
for i in range(len(sized)-1, -1, -1):
tokens, _msg = sized[i]
if tail_tokens + tokens < half_max_tokens:
tail_tokens += tokens
split_index = i
else:
break
head = messages[:split_index]
tail = messages[split_index:]

tail_tokens = 0
split_index = len(messages)
half_max_tokens = self.max_tokens // 2
# Iterate over the messages in reverse order
for i in range(len(sized)-1, -1, -1):
tokens, _msg = sized[i]
if tail_tokens + tokens < half_max_tokens:
tail_tokens += tokens
split_index = i
else:
break
# Ensure the head ends with an assistant message
while messages[split_index - 1]["role"] != "assistant" and split_index < len(messages):
split_index += 1
head = messages[:split_index]
tail = messages[split_index:]
>>>>>>> UPDATED
```
This change ensures that the head of the messages ends with an assistant message.
# Aider chat conversation:
USER: instead of splitting the history in half based on the msg number, split it in half based on the token count
ASSISTANT: To implement this change, we need to modify the `summarize` method in the `ChatSummary` class in the `aider/history.py` file.
The current implementation splits the messages in half based on the number of messages. We need to change this to split the messages based on the token count.
Here are the steps to implement this change:
1. Calculate the total token count of all messages.
2. Iterate over the messages and keep a running total of the token count.
3. Once the running total exceeds half of the total token count, split the messages at that point.
Here is the *edit block* for this change:
```python
aider/history.py
<<<<<<< ORIGINAL
def summarize(self, messages):
num = len(messages)
dump(num)
if num < 2:
return messages
sized = self.tokenize(messages)
total = sum(tokens for tokens, _msg in sized)
if total <= self.max_tokens:
return messages
num = num // 2
# we want the head to end with an assistant msg
while messages[num]["role"] == "assistant" and num < len(messages) - 1:
num += 1
head = messages[:num]
tail = messages[num:]
