Limits | AI Engine Help Center

The fixed limits in AI Engine, such as result sizes, export rows, context caps and request timeouts, plus the Salesforce limits that affect it.

This page lists the limits built into AI Engine and the Salesforce platform limits you are most likely to meet. Limits that you can change are marked as settings.

Chat and results#

What	Limit
Question length	4,000 characters. Longer text is cut off.
Conversation memory	The last 6 messages of the conversation, including the new question, are sent with each question, so follow-up questions work.
Records in a list answer	Up to 200, unless the question asks for fewer. When more match, the answer gives the total and the table offers Show all.
Show all	Up to 2,000 rows in the chat panel.
CSV and Excel export	Up to 10,000 rows. For more, use a Salesforce report or Data Loader.
Reloading a result	Show all, export and column changes work for 4 hours after the answer. After that, ask the question again.
Rows the AI reads for a list answer	The number of matching records and a sample of up to 10 rows. The full table comes from Salesforce directly.
Charts with one grouping	Up to 12 bars or slices: the 11 largest, with the rest combined as "Other".
Charts with two groupings	Up to 12 categories and 8 series. Further series are combined as "Other"; categories beyond the first 12 are not shown in the chart.
Activity Digest	Up to 6 objects, with up to 10 recent records listed per object.

Record context#

What	Limit
Activities in record context	Up to 10 recent tasks, 10 events and 10 Chatter posts. Long notes are shortened.
Child records	Up to 10 records per configured child object.
Meet Prep additional objects	1–20 records per object (Limit setting per object, default 5). Long field values are shortened.
Analyze Email	Up to 32,000 characters of email text per analysis.

Prompt templates#

What	Limit
Data sources per template	Up to 5 active data sources.
Rows per data source	1–200 (Row limit setting, default 50).
Total data-source text per prompt	40,000 characters by default. Longer results are truncated with a note. The cap is the Max Context Chars (Data Sources) field on the active AI Engine Profile record. It is not on the admin tab's Org Profile form, so to change it, an admin with `AI_Engine_Admin` edits the record with a data tool such as Data Loader.

AI Scoring#

What	Limit
Manual batch run	Up to 200 matching records per click. Records that already have a score are skipped unless Re-score already scored records is ticked, so clicking again picks up the next 200.
Won/lost sample size	10–100 (Sample Size setting, default 30).
Scoring context without Scoring Context Fields	Up to 25 fields. With fields selected in Scoring Context Fields, exactly those fields are used.
Verify Company On The Web	One extra web search per scored record. A 200-record batch then makes up to 400 requests to the provider.

Magic Snap#

What	Limit
Photo size	Photos are scaled down to 1,600 pixels on the longest side before upload. Very large images are refused.
Note	Up to 4,000 characters.

AI provider requests#

What	Limit
Request timeout	Each request to the provider waits up to 120 seconds.
Automatic retries	Up to 2 retries when the provider is rate-limited (HTTP 429) or has a temporary server error (HTTP 500, 502, 503).
Chat answer length	Up to 1,000 output tokens per answer.
Record action length	Summary, Next Steps, Draft Email, custom prompts, Meet Prep and PDF templates use Max Output Tokens from the Org Profile or 3,500 tokens, whichever is higher. Analyze Email uses at least 2,000.

Salesforce platform limits#

Concurrent long-running requests. Salesforce limits how many long-running requests an org processes at the same time. When many users start AI actions at the same moment, some may see "Unable to process request. Concurrent requests limit exceeded". Waiting a few seconds and trying again usually resolves it. Schedule scoring batches outside business hours to keep capacity for users.
Email limits. Send Email uses Salesforce email, so your org's daily email limits apply.
PDF fonts. PDFs use the built-in fonts Helvetica, Times and Courier, which cover Latin-1 characters only. Accented letters are converted to plain letters (for example ł becomes l and ü becomes ue), and characters outside Latin-1 are left out.

Trial#

AI Engine includes a free trial of 5 days for up to 3 users, with all features. The trial starts the first time someone in the org uses an AI feature, for example a chat question; opening the License tab does not start it. See License and trial.
