* SimpleChat: A placeholder system prompt, Use usage msg in code
Just have a alert msg wrt needing javascript enabled in html. And
have usage message from js file. Update the usage message a bit.
So also enable switch session wrt setup_ui call.
Add a possible system prompt as a placeholder for the system-input.
* SimpleChat:CompletionMode: Allow control of Role: prefix
* SimpleChat:Completion: Avoid Role: prefix; Newline only in between
In completion mode
* avoid inserting Role: prefix before each role's message
* avoid inserting newline at the begin and end of the prompt
message. However if there are multiple role messages, then
insert newline when going from one role's message to the
next role's message.
* SimpleChat:CompletionMode: Update readme/usage, trim textarea newline
Readme update wrt completion mode behavior.
Usage help updated wrt completion mode behavior.
When changing from input to textarea elment wrt user input, the last
newline at the end of the user input wrt textarea, was forgotten to be
filtered, this is fixed now. However if user wants to have a explicit
newline they can using shift+enter to insert a newline, that wont be
removed. The extra newline removal logic uses substring and keyup to
keep things simple and avoid some previously noted bugs wrt other
events in the key path as well as IME composition etal.
* SimpleChat:SC: Ensure proper clearing/reseting
previous logic would have cleared/reset the xchat, without doing
the same wrt iLastSys, thus leading to it pointing to a now non
existent role-content entry.
So if a user set a system prompt and used completion mode, it would
have done the half stupid clear, after the model response was got.
Inturn when user tries to send a new completion query, it would
inturn lead to handle_user_submit trying to add/update system prompt
if any, which will fail, bcas iLastSys will be still pointing to a
non existant entry.
This is fixed now, by having a proper clear helper wrt SC class.
* SimpleChat: Update usage note and readme a bit
* SimpleChat:Completion: clear any prev chat history at begining
Previously any chat history including model response to a completion
query would have got cleared, after showing the same to the user,
at the end of handle_user_submit, rather than at the begining.
This gave the flexibility that user could switch from chat mode
to completion mode and have the chat history till then sent to
the ai model, as part of the completion query. However this flow
also had the issue that, if user switches between different chat
sessions, after getting a completion response, they can no longer
see the completion query and its response that they had just got.
The new flow changes the clearing of chat history wrt completion
mode to the begining of handle_user_submit, so that user doesnt
lose the last completion mode query and response, till a new
completion mode query is sent to the model, even if they were to
switch between the chat sessions. At the same time the loss of
flexibility wrt converting previous chat history into being part
of the completion query implicitly doesnt matter, because now
the end user can enter multiline queries.
* SimpleChat:Try read json early, if available
For later
the server flow doesnt seem to be sending back data early, atleast
for the request (inc options) that is currently sent.
if able to read json data early on in future, as and when ai model
is generating data, then this helper needs to indirectly update
the chat div with the recieved data, without waiting for the
overall data to be available.
* SimpleChat: Rename the half asleep mis-spelled global var
* SimpleChat: Common chat request options from a global object
* SimpleChat: Update title, usage and readme a bit
Keep the title simple so that print file name doesnt have chars
that need to be removed.
Update readme wrt some of the new helpers and options.
Change Usage list to a list of lists, add few items and style it
to reduce the margin wrt lists.
* SimpleChat:ChatRequestOptions: max_tokens
As some times based on the query from the user, the ai model may get
into a run away kind of generation with repeatations etal, so adding
max_tokens to try and limit this run away behaviour, if possible.
* SimpleChat: Reduce max_tokens to be small but still sufficient
* SimpleChat: Consolidate global vars into gMe, Display to user
This allows the end user to see the settings used by the logic,
as well as allows users to change/update the settings if they
want to by using devel-tools/console
* SimpleChat:SlidingWindow: iRecentUserMsgCnt to limit context load
This is disabled by default. However if enabled, then in addition
to latest system message, only the last N user messages, after the
latest system message and its reponses from the ai model will be sent
to the ai-model, when querying for a new response.
This specified N also includes the latest user query.
* SimpleChat: placeholder based usage hint for user-in textarea
* SimpleChat: Try make user experience better, if possible
Reduce chat history context sent to the server/ai-model to be
just the system-prompt, prev-user-request-and-ai-response and
cur-user-request, instead of the previous full chat history.
This way if there is any response with garbage/repeatation, it
doesnt mess with things beyond the next question, in some ways.
Increase max_tokens to 1024, so that a relatively large previous
reponse doesnt eat up the space available wrt next query-response.
However dont forget that the server when started should also
be started with a model context size of 1k or more, to be on
safe side.
Add frequency and presence penalty fields set to 1.2 to the set
of fields sent to server along with the user query. So that
the model is partly set to try avoid repeating text in its
response.
* SimpleChat:Add n_predict (equiv max_tokens) for llamacpp server
The /completions endpoint of examples/server doesnt take max_tokens,
instead it takes the internal n_predict, for now add the same on
the client side, maybe later add max_tokens to /completions endpoint
handling.
* SimpleChat: Note about trying to keep things simple yet flexible
* main : don't print special tokens with --grammar
The CLI interface was recently changed to print special control tokens
like the </s> stop message one. This token shouldn't be printed if the
grammar flag was passed, unless the grammar specifies it, because that
breaks shell-scriptability.
* main: use seperate stream for control characters
* main: use dprintf and add --ctrl-token-no-out and --ctrl-token-fd-out
* main: dprintf isn't part of the IEEE POSIX standard. Just use write().
* main: remove --ctrl-token-fd-out in favor for fcntl() based detection
* common.cpp: accidentally removed --interactive-first
* main: only merge stdout and control token if not in conversation or grammar mode
* main: rejig control token descriptor handling
* main: must check pipe status on very top of program
* main: renamed --no-special from --ctrl-token-no-out and other refactoring
* main: refactor ctrl_token_no_out --> no_special
* llama: rename llama_token_is_control_token() to llama_token_is_control()
* main: remove special token file descriptor feature (#5)

* Make tokenizer.cpp CLI tool nicer.
Before this commit, tokenize was a simple CLI tool like this:
tokenize MODEL_FILENAME PROMPT [--ids]
This simple tool loads the model, takes the prompt, and shows the tokens
llama.cpp is interpreting.
This changeset makes the tokenize more sophisticated, and more useful
for debugging and troubleshooting:
tokenize [-m, --model MODEL_FILENAME]
[--ids]
[--stdin]
[--prompt]
[-f, --file]
[--no-bos]
[--log-disable]
It also behaves nicer on Windows now, interpreting and rendering Unicode
from command line arguments and pipes no matter what code page the user
has set on their terminal.
* style fix: strlen(str) == 0 --> *str == 0
* Simplify tokenize.cpp; by getting rid of handling positional style arguments.
It must now be invoked with long --model, --prompt etc. arguments only.
Shortens the code.
* tokenize.cpp: iostream header no longer required

* SimpleChat: Add a skeletal html page
Contains a div placeholder for showing chat messages till now
a text-input for allowing user to enter next chat message/query
to the model.
a submit button to allow sending of the user entered message and
chat till now to the model.
* SimpleChat: A js skeleton with SimpleChat class
Allows maintaining an array of chat message.
Allows adding chat message (from any of the roles be it system,
user, assistant, ...)
Allows showing chat messages till now, in a given div element.
* SimpleChat: request_json, globals, startme
* SimpleChatJS: Roles Class, submitClick
Define Role class with static members corresponding to the roles.
Update startme to
* Get hold of the ui elements.
* Attach a click handler to submit button, which adds the user input
to xchats array and shows the chat messages till now in chat div
element.
Trap DOMContentLoaded to trigger startme
* SimpleChat:HTML: Bring in the js file
* SimpleChat: Rather value wrt input text element
* SimpleChat: Also add completions related prompt
* SimpleChat: Use common helper logic wrt json data
* SimpleChat: Move handling of submit request into its own func
* SimpleChat: Try handshake with llm over its web service endpoint
* SimpleChat:JS: Extract model response and show to user
* SimpleChat:JS: Messages/Prompt, indicate working to end user
* SimpleChat: Try keep input element in view
* SimpleChat: Diff user/assistant msgs, Make input wider
Also show a default message to user
Also add some metas
* SimpleChat: Move into its own sub directory to avoid confusion
* SimpleChat:sh: Add simple shell script to run python3 http.server
So one needs to run the llm server locally
then run this script and access it using a local browser
* SimpleChat:JS: Try trap enter key press wrt input text field
So user can either press submit button or press enter key
* SimpleChat: Allow user to select chat or completion mode
* SimpleChat: Dont submit if already submitted and waiting
Also make chat the default selection wrt mode
* SimpleChat:JS: Handle difference in response
Try read the assistance response from appropriate field in the
response got.
Also examples/server seems to return the response in a slightly
different field, so try account for that also.
* SimpleChat:JS: Force completion mode be single message by default
* SimpleChat: Add a simple readme file
* SimpleChat:HTML: Cleanup/structure UI a bit, Add input for system
* SimpleChat:Allow system prompt to be set, if provided before user
* SimpleChat: Ignore empty user input, without trimming
* SimpleChat:Alert user if they provide sysprompt late or change it
* SimpleChat: Move handling systemprompt into its own func
* SimpleChat:HTML: Add a style for system role message
* SimpleChat: Update the readme file
* SimpleChat:CSS: Move style info into its own css file
To keep it simple, clean and seperate so that things are not
unnecessarily cluttered.
* SimpleChat:CSS: Allow for chat div to be scrollable
* SimpleChat:JS: Try ensure the last entry in chat is visible
Needed because now only the chat div is scrollable and not the full
page.
In last commit the chat div size was fixed to 75% vertical height,
so the full page no longer scrolls, so the old bring user-input
element to view wont work, instead now the last element in the
chat div should be brought into view.
* SimpleChat:JS: bottom of element visible, Set focus to user input
As the generated text could be multiple lines and occupy more space
that the full scrollable div's vertical space, make the bottom of
the last element (which can be such a generated text) in the div
visible by scrolling.
Ensure that the user input box has focus
* SimpleChat: Update notes a bit. Try keep browser happy
Avoid browser quirk mode with DOCTYPE.
Help with accessibility a bit by specifying the language explicitly.
Specify the char encoding explicitly, inturn utf-8 is a safe bet,
even with intermixing of languages if reqd in future.
Add a cache-control http-equiv meta tag, which in all probability
will be ignored.
Defer js loading and execution, just for fun and future, not that
critical here as it stands now.
* SimpleChat:HTML:Group user input+btn together; Note about multichat
* SimpleChat:JS: Allow for changing system prompt anytime for future
* SimpleChat:Readme: Note about handle_systemprompt begin/anytime
* SimpleChat:HTML: Add viewport meta for better mobile friendliness
Without this the page content may look too small.
* SimpleChat:HtmlCss: Cleanup UI flow
set margin wrt vmin rather than vw or vh so portrait/landscape ok.
Use flex and flex-grow to put things on the same line as well as
distribute available space as needed. Given two main elements/line
so it remains simple.
In each line have one element with grows and one sits with a basic
comfortably fixed size.
* SimpleChat: textarea for multiline user chat, inturn shift+enter 4 enter
* SimpleChat: Make vertical layout better responsive (flex based)
Also needed to make things cleaner and properly usable whether
landscape or portrait, after changing to multiline textarea rather
than single line user input.
Avoid hardcoding the chat-till-now display area height, instead
make it a flex-growable within a flex column of ui elements within
a fixed vertical area.
* SimpleChat: Rename simplechat.html to index.html, update readme
Instead of providing a seperate shell script, update the readme wrt
how to run/use this web front end.
* SimpleChat: Screen fixed view and scrolling, Printing full
* SimpleChat:JS:CI: Avoid space at end of jsdoc param line
* SimpleChat:JS: MultiChat initial skeleton
Will help maintain multiple independent chats in future
* SimpleChat:JS: Move system prompt begin/anytime into SimpleChat
* SimpleChat:JS:Keep MultiChatUI simple for now
Worry about different chats with different servers for later.
* SimpleChat:JS: Move handle submit into MultiChat, build on same
Create an instance of MultiChatUI and inturn a instance of chat
session, which is what the UI will inturn work on.
* SimpleChat:JS: Move to dictionary of SimpleChat, instead of array
* SimpleChat: Move ui elements into MultiChatUI, Update el IDs
Move ui elements into MultiChatUI, so that current handleUserSubmit
doesnt need to take the element arguments. Also in future, when
user is allowed to switch between different chat sessions, the
UI can be updated as needed by using the elements in UI already
known to MultiChatUI instance.
Rename the element ids' so that they follow a common convention,
as well as one can identify what the element represents in a more
consistant manner.
* SimpleChat:MCUI:Show available chat sessions, try switch btw them
Previous commits brought in / consolidated existing logic into
MultiChatUI class.
Now start adding logic towards multichat support
* show buttons indicating available chat sessions
* on sessin button click, try switch to that session
* SimpleChat:MCUI: Store and use current chat session id
Also
allow to switch chat session optionally, wrt some of the related
helpers.
setup for two chat sessions by default.
* SimpleChat:MCUI: Delay enabling user-input to avoid race
Re-enable user-input, only after response to a user query has been
updated to the chat-div. This ensures that if user tries to switch
chat session, it wont be allowed till chat-request-response flow is
done.
* SimpleChat: Take care of system prompt
Helper to get the latest system prompt and inturn use same to
set the system prompt ui, when switching.
Ensure that system prompt is set if and when enter key is pressed.
* SimpleChat:GetSystemLatest, fix a oversight.
* SimpleChat:MCUI: Allow selected chat-session btn to be highlighted
Also have a general helper for setting class of children.
* SimpleChat:Cleanup corners
Show system prompt in chat space, when it is set by pressing enter,
as a feedback to user.
Alert user, if they try to switch chat session in the middle of
waiting for a response from the ai model.
* SimpleChat:MCUI: Ensure req-resp failure doesnt lock up things
* SimpleChat:MCUI: Support for new chat sessions
Also a general create button helper.
* SimpleChat:MCUI: CreateSessionBtn helper, use wrt NewChat
Also fix a oversight wrt using stale data wrt the list of chat
sessions.
* SimpleChat:MCUI: NewChat btn first before existing chat sessions
* SimpleChat:MCUI:CornerCases:Skip new chat, show only if current
Skip NewChat if user cancels or if one waiting for response from
the ai model.
Dont show a chat with newly got ai model response, if current chat
session has changed, some how. Chat session shouldnt be allowed to
change, if there is a pending response, but still as a additional
sanity check.
* SimpleChat: Update readme, title, show usage if no chat to show
* SimpleChat: Cleanup the log/dialog messages a bit
* phi3 : duplicate rope factors in each layer
phi3 : set phi-3 model type as 14B

The llama.cpp grammar parser had a bug where forgetting to add a closing
quotation mark to strings would cause parsing to crash. Anyone running a
server on a public endpoint is advised to upgrade. To reproduce this bug
./llamafile -m foo.gguf -p bar --grammar 'root::="'
Credit for discovering and reporting this issue goes to Eclypsium
Security Researcher Richard Johnson <Richard.johnson@eclypsium.com>.
* Revert "Revert "llava : add support for moondream vision language model (#6899)""
This reverts commit 9da243b36a.
* Fix num_positions and embeddings initialization
* convert-hf : begin refactoring write_tensor
* convert : upgrade to sentencepiece v0.2.0
* convert-hf : remove unused n_dims in extra_*_tensors
* convert-hf : simplify MoE weights stacking
* convert-hf : flake8 linter doesn't like semicolons
* convert-hf : allow unusual model part names
For example, loading `model-00001-of-00001.safetensors` now works.
* convert-hf : fix stacking MoE expert tensors
`torch.stack` and `torch.cat` don't do the same thing.
* convert-hf : fix Mamba conversion
Tested to work even with a SentencePiece-based tokenizer.
* convert : use a string for the SentencePiece tokenizer path
* convert-hf : display tensor shape
* convert-hf : convert norms to f32 by default
* convert-hf : sort model part names
`os.listdir` is said to list files in arbitrary order.
Sorting the file names should let "model-00009-of-00042.safetensors"
be loaded before "model-00010-of-00042.safetensors".
* convert-hf : use an ABC for Model again
It seems Protocol can't be used as a statically type-checked ABC,
because its subclasses also can't be instantiated. (why did it seem to work?)
At least there's still a way to throw an error when forgetting to define
the `model_arch` property of any registered Model subclasses.
* convert-hf : use a plain class for Model, and forbid direct instantiation
There are no abstract methods used anyway,
so using ABC isn't really necessary.
* convert-hf : more consistent formatting of cmdline args
* convert-hf : align the message logged for converted tensors
* convert-hf : fix Refact conversion
* convert-hf : save memory with lazy evaluation
* convert-hf : flake8 doesn't like lowercase L as a variable name
* convert-hf : remove einops requirement for InternLM2
* convert-hf : faster model parts loading
Instead of pre-loading them all into a dict, iterate on the tensors
in the model parts progressively as needed in Model.write_tensors
Conversion for some architectures relies on checking for the presence
of specific tensor names, so for multi-part models, the weight map is read
from the relevant json file to quickly get these names up-front.
* convert-hf : minor changes for consistency
* gguf-py : add tqdm as a dependency
It's small, and used for a progress bar
in GGUFWriter.write_tensors_to_file
* Added themes support with two sample themes and a favicon.

* Introduce bfloat16 support
Many models on Hugging Face (e.g. Mistral, TinyLLaMA) use bfloat16 as
their canonical floating point format.
┌sign
│
│ ┌exponent
│ │
│ │ ┌mantissa
│ │ │
│┌──┴───┐┌─┴───┐
0b0000000000000000 brain16
This encoding has the same number of exponent bits as float32. That
makes conversion relatively straightforward, even in the absence of
hardware support. For example, converting brain16 to binary32 means
simply shifting 16 bits to the left.
┌sign
│
│ ┌exponent
│ │
│ │ ┌mantissa
│ │ │
│┌──┴───┐┌─┴───────────────────┐
0b00000000000000000000000000000000 IEEE binary32
The issue is that converting bf16 to fp16 can result in information
loss. Only 13% of bf16 numbers can be precisely represented in fp16
which in practice ends up being 99.71% of Mistral 7b v0.2's weights
however there is currently no way other than fp32 to get the others
┌sign
│
│ ┌exponent
│ │
│ │ ┌mantissa
│ │ │
│┌─┴─┐┌─┴──────┐
0b0000000000000000 IEEE binary16
This change fixes that, by adding a bf16 data type to GGML. Support
for CPU inference has been implemented along with optimizations for
the AVX2, AVX512, and AVX512BF16 ISAs. Perplexity on Mistral 7b 0.2
improves somewhere around -0.0024 to -0.0046 compared to using fp16
* Remove GGML code that's not needed
* Minimize the GGML API surface area for BF16
* Remove bf16 luts
* Make the GGML header look nicer
* Fix documentation
* Apply ggerganov's fixes for test-backend-ops
* Add BF16 code for new ggml_validate_row_data() function
* Fixed save_imatrix to match old behaviour for MoE
This fix is simple and clear, but unnecessarily doubles the memory overhead..
* Fixed missing idx variable
* Unconditionally increment ncall

* Fixed 2 bugs in save_imatrix()
- Fixed segfault bug because the counts vector needed to be created.
- Fixed pre-existing bug didn't actually add to the counts for "--combine" option.
* ncall needs summing too
* Trailing whitespace

* Update log text (EOS to EOG)
The log text "found EOS" is no longer always correct, here, because there is now an is-EOG check that also returns true for EOT.
* Improve log msg. further by using "an" instead of "some".
As suggested, to avoid misunderstanding (no multiple EOG tokens found, just one).

This required making the following changes to the CLIP model:
1. Support for patch embedding bias.
2. Make class embedding and pre-layernorm optional.
3. Add support for post-layernorm.
* Update examples/llava/clip.cpp

This commit renamesthe lerp (linear interpolation) function in clip.cpp
to avoid a conflict with the lerp function in the <cmath> standard C++
library when using c++20.
The motivation for this change is to enable projects that use c++20 to
be able to compile clip.cpp without having to resort to patching it. The
lerp function was added to cmath in version C++20 (202002L) and is why
this is not causing any issue at the moment as C++11/C++17 is currently
used by llama.cpp.
I realize that llama.cpp uses either C++11 (or C++17 in the case for
SYCL) but wanted to ask if this would be an acceptable change just the
same.

* fix: revert showing control tokens by default
* feat: revert changes to default behavior of llama_token_to_piece; provide overridden declaration to receive "bool special" param to toggle showing control tokens
* feat: use the overridden declaration of llama_token_to_piece from common/common.cpp to specify "false" so that control tokens are not shown in chat completion responses"
* common : simplify
